Published: March 2019

Objectives. To evaluate the association of state dense breast notification (DBN) laws with use of supplemental tests and cancer diagnosis after screening mammography.

Methods. We examined screening mammograms (n = 1 441 544) performed in 2014 and 2015 among privately insured women aged 40 to 59 years living in 9 US states that enacted DBN laws in 2014 to 2015 and 25 US states with no DBN law in effect. DBN status at screening mammography was categorized as no DBN, generic DBN, and DBN that mandates notification of possible benefits of supplemental screening (DBN+SS). We used logistic regression to examine the change in rate of supplemental ultrasound, magnetic resonance imaging, breast biopsy, and breast cancer detection.

Results. DBN+SS laws were associated with 10.5 more ultrasounds per 1000 mammograms (95% CI = 3.0, 17.6 per 1000; P = .006) and 0.37 more breast cancers detected per 1000 mammograms (95% CI = 0.05, 0.69 per 1000; P = .02) compared with no DBN law. No significant differences were found for generic DBN laws in either ultrasound or cancer detection.

Conclusions. DBN legislation is associated with increased use of ultrasound and cancer detection after implementation only when notification of the possible benefits of supplemental screening is required.
Texting-While-Driving Bans and Motor Vehicle Crash–Related Emergency Department Visits in 16 US States: 2007–2014
Authors: Ferdinand Alva O. , Aftab Ammar , Akinlotan Marvellous A.
Published: March 2019

Objectives. To examine the impact of state texting bans on motor vehicle crash (MVC)–related emergency department (ED) visits.

Methods. We used ED data from 16 US states between 2007 and 2014. We employed a difference-in-difference approach and conditional Poisson regressions to estimate changes in counts of MVC-related ED visits in states with and without texting bans. We also constructed age cohorts to explore whether texting bans have differential impacts by age group.

Results. On average, states with a texting ban saw a 4% reduction in MVC-related ED visits (incidence rate ratio = 0.96; 95% confidence interval = 0.96, 0.97). This equates to an average of 1632 traffic-related ED visits prevented per year in states with a ban. Both primary and secondary bans were associated with significant reductions in MVC-related visits to the ED regardless of whether they were on all drivers or young drivers only. Individuals aged 64 years and younger in states with a texting ban saw significantly fewer MVC-related ED visits following its implementation.

Conclusions. Our findings suggest that states’ efforts to curb distracted driving through texting bans and decrease its negative consequences are associated with significant decreases in the incidence of ED visits that follow an MVC.
In 2040, Will There Be Jobs for Petroleum Engineers?
Authors: Rassenfoss Stephen
Published: March 2019

BP’s detailed Energy Outlook 2019 can be reduced to a single question: Is petroleum engineering a good, long-term career choice for a college student?

The short answer from BP CEO Bob Dudley is yes. “I am not worried about young people coming into the industry,” he said.

The evidence for that was in the company’s latest annual outlook, which examined several possible scenarios of the energy future, all of which will require finding and producing a lot more oil.

The scenarios predict needed oil production ranging from 80–130 million B/D in 2040, depending on how energy demand grows, said Spencer Dale, group chief economist for BP (Fig. 1). While he said he does not know which scenario, if any, will prove accurate, all require trillions of dollars of exploration and production (E&P) spending to deliver that much oil.

Engineers will be busy meeting the growing demand from developing countries, particularly in Asia, where rising standards of living will drive more consumption. It is a trend often missed by those in Europe and the US, where energy demand is expected to continue to be flat, he said.

In countries with fast-growing energy needs, the allure of energy engineering jobs also tends to be higher. “Around the world it (an E&P company) is one of the most popular places to go to work. But not where we live,” Dudley said, referring to the United Kingdom, where the briefing on the new outlook was held.

Oil production will remain high, but could peak in 2030, and gas demand will rise over the next 20 years, according to the outlook. Renewable sources of energy will grow at a far faster rate, but wind and solar alone will not be able to meet demand from countries such as India and China where billions of people are moving from poverty into the middle class and spending money on appliances, cars, and air conditioners, among many other things.

“The growing middle class in the developing world, especially in Asia, is the major factor accounting for global economic growth over the next 20 years,” and that will make it a key driver of energy growth, Dale said.

Conflicting Priorities

The US and European view on the future of energy is a zero-sum game. Those concerned about carbon emissions causing climate change call for replacing fossil fuels with renewable energy sources. In a country with flat demand, new capacity must replace old facilities.

The equation is more complicated in the growing economies of Asia and Africa. There, energy demand is growing so rapidly that more of all types of energy will be needed. That is good news for many petroleum engineers who are delivering a rising stream of oil and gas for export.

Dudley said the message he heard at a recent conference in Africa was “we need cooking fuel and reliable electricity.” With so many young workers entering the job market, they need “heavy energy to create manufacturing that puts people to work,” he said.
E&P Leaders Gather for Arctic Technology Conference
Authors: Pai Sudhir
Published: March 2019

More than 250 industry leaders involved in Arctic E&P gathered for the 2018 Arctic Technology Conference recently in Houston. Supported by the Offshore Technology Conference’s network of scientific and professional societies, the conference provided a platform for collaboration among colleagues, vendors, and academia to reveal innovations, solutions, ideas, and emerging technologies for both onshore and offshore activities in the Arctic basins.

The conference presented a highly specialized program that included more than 70 technical presentations, six panel discussions, and four topical breakfasts and luncheons.

The Distinguished Achievement Award ceremony recognized the major technological, humanitarian, environmental, and leadership contributions of an individual and an organization. Due to his contributions and accomplishments in the industry, Kenneth Bird was awarded the Distinguished Achievement Award for Individuals. As a petroleum geologist, Bird led assessment teams to produce a series of scientifically sound, methodologically rigorous, and policy-neutral products widely accepted in Alaska and the global Arctic regions. Since the 1980s, Bird has been at the forefront of resource-assessment projects that have been executed by the US Geological Survey. The National Research Council (NRC) of Canada was presented the Distinguished Achievement Award for their involvement in the development of Arctic tools and technologies. For more than 60 years, NRC Canada has provided regulatory, operational, and engineering design support to clients.

There is a Future in the Arctic

The current economic and business environment is challenging to conduct safe and environmentally friendly hydrocarbon exploration and development in the Arctic. However, the Arctic continues to be a region of close observation to use relevant technology, respecting local requirements, and be ready for a time when we see a step up and acceleration of activity.

In spite of a reduction of E&P activity in the Arctic, this conference continues to attract interest for several reasons:

It is by far the premier event focused on the Arctic, not just E&P but also mining, shipping, logistics, environment, and, most importantly, the local people and communities.

It is a platform for the passionate community to meet, network, and present quality technical papers. The 2018 event attracted 103 abstracts, which translated to 70 presentations split into 12 technical sessions. Six panel discussions, and four topical breakfasts and luncheons focused on current themes with specific regional focus from the Chukchi (US), through Beaufort, (Canada), through Barents (Finland and Norway) seas.

Exhibiting companies showcased their latest products and innovations to specialized decision makers focused on finding unique solutions for successful operations in this area.

Technology Focus: History Matching and Forecasting (April 2019)
Authors: Emerick Alexandre
Published: March 2019

Technology Focus

Machine-learning methods have gained tremendous attention in the last decade. These methods are tackling and solving complex problems with impressive results in many different areas. Buzzwords such as “big data” and “deep learning” are now part of our everyday vocabulary. The underlying idea behind machine learning is that computers can identify patterns and learn from data with minimal human intervention. This is not very different from the notion of automatic history matching. Actually, the similarities are more profound: Both machine learning and history-matching methods use the same mathematical tools, such as linear algebra, optimization, Bayesian inference, and Monte Carlo sampling. In fact, I believe that machine learning is a natural research direction to improve our current history-matching methods.

At this point, some readers must be thinking about the risks of automated processes. They may very well claim that there are no surrogates for experience, a thorough understanding of the reservoir production mechanisms, and attention to the practical aspects and limitations of the models. After all, if machines can learn, humans can think. I am not trying to say otherwise. My only point is that we cannot ignore the recent developments in machine learning and we must not turn a blind eye to what computer-aided strategies can offer. If used responsibly, they can help us achieve better results in less time.

To conclude, I would like to point out that machine-learning methods may also find very interesting applications in data-driven production forecasts. In fact, data-driven methods are not new in the petroleum literature; see, for example, decline-curve analysis. These methods are used currently as complements (and often alternatives) to model-driven approaches. Machine-learning methods have much to offer in this regard, especially in cases with an abundance of data.

ARE MUSLIMS PRACTISING MODERATION IN THEIR FINANCIAL DECISIONS?
Authors: Roslily Ramlee  , Sharifah Raihan Syed Mohd Zain  , Wan Rohaida Wan Husain
Published: March 2019

Statistics and a survey of the literature revealed the existence of a massive problem in the financial prudence of Malaysians, including Muslims. One glaringly prominent aspect is the absence of a spiritual/religious interventionist approach in exploring the lack of consumer awareness that led to the present situation. Instead of attempting to solve the problem through brute economic policies, a wasatiyyah-oriented approach is warranted for informing consumers of their religious obligation to avoid profligate spending and adopt moderation in financial matters. Hence, the objective of this study is to examine the practice of moderation (the concept of wasatiyyah) among Muslims consumers in their financial decision-making. Primary data were collected through a self-administrated survey on a selected group of Muslim consumers. A relevant statistical software was employed to perform exploratory-factor analysis (EFA) through principal-component analysis (PCA), confirmatory factor analysis (CFA), and structural equation modelling (SEM) on the collected data. The findings demonstrated that moderation (wasatiyyah) partially mediates the relationship between materialism and financial decisions. Consequently, Muslim consumers who practice moderation while making their financial decisions are more conscious of their credit management and thus spend according to their means.

ESPECULAÇÕES SOBRE A AUTOPOIESE DA NARRATIVA LITERÁRIA
Authors: Preger Guilherme
Published: March 2019

O trabalho propõe uma reflexão especulativa sobre a narrativa literária como subsistema autopoiético social, como extensão do conceito teórico de Niklas Luhmann de autopoiese (autopoiesis), aplicado nas ciências sociais.  Nossa hipótese especula como a narrativa literária pode ser descrita como uma forma de comunicação social  e de “observação de segunda ordem” (observação da observação). No entanto, a narrativa literária se distingue da narrativa social como uma “auto-observação” narrativa ou narrativa da narrativa. O que interessa à narrativa literária não é a descrição de fatos, ações ou personagens, mas as relações de níveis narrativos no momento de sua autorreprodução. Com isso, será proposto um cruzamento entre  a Teoria dos Sistemas Sociais de Luhmann com a Teoria da Narratologia, em particular como apresentada  na  obra de Gerard Genette.   Assim, a diferença entre o nível narrativo (diegesis) e o nível de focalização da história corresponde à diferença entre observação de segunda e de primeira ordens.  Será visto que a resolução dos paradoxos surgidos na circularidade da auto-observação do sistema literário é realizada pela formação de “cronotopos”, conceito da obra de Mikhail Bakhtin, isto é, como uma extensão no tempo e no espaço do domínio do imaginário.

Historicamente os estudos da informação se relacionam diretamente com os estudos da linguagem. Recentemente, entra nesse cruzamento, a tecnologia. Procurando identificar caminhos que possam servir aos estudos informacionais para refletir e construir suas estruturas de linguagem para mediação do conhecimento, é desenvolvido um ensaio sobre qual seria o lugar da linguagem na obra “Ensaio sobre a origem dos conhecimentos humanos” (1746), de Étienne Bonnot de Condillac (1715 – 1780). Procura-se, ao final, defender as perspectivas do filósofo como um dos pontos de partida prévios que poderiam também ser assumidos pela Ciência da Informação para distinguir aquilo que atualmente concebemos como linguagem, conhecimento e uso da informação.
Real-Time Access to Electronic Health Record via a Patient Portal in a Tertiary Hospital: Is it Harmful? A Retrospective Mixed Methods Observational Study (Preprint)
Authors: van Kuppenveld Savannah IR , van Os-Medendorp Harmieke , Tiemessen Nicole AM , van Delden Johannes JM
Published: March 2019

BACKGROUND

The rapid implementation of patient portals, through which patients can view their electronic health record, creates possibilities for information exchange and communication between patients and health care professionals. However, real-time disclosure of test results and clinical reports poses a source of concern.

OBJECTIVE

This study aimed to examine negative experiences resulting from real-time disclosure of medical information through a patient portal.

METHODS

Data were collected over a 2-year period in 4 datasets consisting of incidents reported by health care professionals, complaints of patients, patient issues at a portal helpdesk, and a survey among health care professionals. Incidents, complaints, issues, and answers on the survey were counted and analyzed through an iterative process of coding.

RESULTS

Within the chosen time frame of 2 years, on average, 7978 patients per month logged into the portal at least once. The amount of negative incidents and complaints was limited. A total of 6 incidents, 4 complaints, and 2506 issues at the helpdesk concerning the patient portal were reported, of which only 2, 1, and 3 cases of these respective databases concerned real-time disclosure of medical information through the patient portal. Moreover, 32 out of 216 health care professionals reported patients that had negative experiences with real-time disclosure. Most negative consequences concerned confused and anxious patients when confronted with unexpected or incomprehensible results.

CONCLUSIONS

Real-time access through a patient portal did not substantially result in negative consequences. The negative consequences that did occur can be mitigated by adequate preparation and instruction of patients concerning the various functionalities of the patient portal, real-time disclosure of test results in particular, and can also be managed through educating health care professionals about the patient portal and making adjustments in the daily practice of health care professionals.

Authors: Hirano Ryoma , Yamaguchi Satoko , Waki Kayo , Kimura Yoshihiko , Chin Keiichi , Nannya Yasuhito , Nangaku Masaomi , Kadowaki Takashi , Ohe Kazuhiko
Published: March 2019

BACKGROUND

Personal health record (PHR) systems let individuals utilize their own health information to maintain and improve quality of life. Using PHRs is expected to support self-management in patients with lifestyle-related diseases.

OBJECTIVE

The aim of this study was to identify predictors of the willingness to use PHRs among patients who are prescribed medications for lifestyle-related diseases.

METHODS

We recruited pharmacy patrons, aged 20 years or older, who had received at least one medication indicated for hypertension, dyslipidemia, or diabetes. Participants completed self-administered questionnaires regarding their previous diseases, awareness of health care, experience in using PHRs, willingness to use PHRs, and barriers to using PHRs. Data were analyzed using multivariate logistic regression models.

RESULTS

Of the 3708 subjects meeting eligibility criteria, 2307 replies (62.22%) were collected. While only 174 (7.54%) participants had previous PHR experience, 853 (36.97%) expressed willingness to use PHRs. In the multivariate analysis, considering exercise to be important for health management (odds ratio [OR] 1.57, 95% CI 1.12-2.21; P=.009), obtaining medical information from books or magazines (OR 1.23, 95% CI 0.96-1.59; P=.10), and obtaining medical information from the internet (OR 1.45, 95% CI 1.13-1.87; P=.004) were newly identified predictors. These were in addition to known predictors, such as being employed, owning information terminals, and previous PHR experience.

CONCLUSIONS

Patients who have an active and positive attitude toward health seem to be more willing to use PHRs. Investigating willingness should contribute to the development of more useful PHRs for self-management among patients prescribed medications for lifestyle-related diseases.

Authors: Taskiran Murat , Cimen Yetis Sibel
Published: March 2019

BACKGROUND

Various images and videos are uploaded every day or even every second on Instagram. These publicly available images are easily accessible as a result of uncontrolled Internet use by young people and children. Shared images include tobacco products and can be encouraging for young people and children when they are accessible.

OBJECTIVE

In this study, it is aimed to detect tobacco and tobacco products with various Convolutional Neural Networks (CNNs).

METHODS

A total of 1607 public images were collected from Instagram, and feature vectors were extracted with various CNNs, which proved to be successful in the competitions and CNN was determined to be proper for this problem.

RESULTS

MobileNet gave the highest results 99.1% as weighted average. The feature vector of the input images are extracted with CNNs and classified with the latest fully connected layer.

CONCLUSIONS

The classification of the tobacco products of 4 different classes was studied by using the networks and the classification performance rate was obtained as 100% for 322 test images via MobileNet. In this way, the content that is encouraging for children can be censored or filtered with a high accuracy rate and a secure Internet environment can be provided.
Understanding Health Behavior Technology Engagement: Pathway to Measuring Digital Behavior Change Interventions (DBCI) (Preprint)
Authors: Cole-Lewis Heather , Ezeanochie Nnamdi , Turgiss Jennifer
Published: March 2019

UNSTRUCTURED

Researchers and practitioners of Digital Behavior Change Interventions (DBCI) use varying and oftentimes incongruent definitions of the term “engagement;” thus, leading to lack of precision in DBCI measurement and evaluation. The objective of this paper is to propose discrete definitions for various types of user-engagement and explain why precision in the measurement of these engagement types is integral to ensuring intervention effectiveness. Additionally, this paper presents a framework and practical steps for how engagement can be measured in practice and used to inform DBCI design and evaluation.
The key purpose of a DBCI is to influence change in a target health behavior of a user, which may ultimately improve a health outcome. Using available literature and practice-based knowledge of DBCI, the framework conceptualizes two primary categories of engagement that must be measured in DBCI. The categories are health behavior engagement, referred to as “Big E” and digital behavior change intervention (DBCI) engagement, referred to as “Little e.” DBCI engagement is further bifurcated into two sub-classes: 1) user interactions with features of the intervention designed to encourage frequency of use (i.e., simple login, games, social interactions) and make the user experience appealing; and 2) user interactions with behavior change intervention components (i.e., behavior change techniques) which influence determinants of health behavior-- and subsequently, influence health behavior.
Achievement of Big E, health behavior engagement, in an intervention delivered via digital means, is contingent upon Little e, DBCI engagement. If users do not interact with DBCI features and enjoy the user experience, exposure to behavior change intervention components will be limited and less likely to influence the behavioral determinants that lead to Big E, health behavior engagement. Big E, health behavior engagement, is also dependent upon the quality and relevance of the behavior change intervention components within the solution. Therefore, the combination of user interactions and behavior change intervention components create Little e, DBCI engagement, which in turn is designed to improve Big E, health behavior engagement.
The proposed framework includes a model to support measurement of DBCI that describes categories of engagement, and details how features of Little e produce Big E. This framework can be applied to DBCI supporting various health behaviors and outcomes; and can be utilized to identify gaps in intervention efficacy and effectiveness.
New Literary Genres—An Insight in the Creativity Optimization
Authors: ACAR PhD student Coculiana
Published: March 2019

The theory of literary genres, developed from antiquity to the present day, has been differently approached, more or less convincingly. The philosophical insight of the genders definition appears at Hegel, A.W. Schlegel, Schelling, each of them trying to follow the particularities of each genre depending on the way to report consciousness to reality and to the issue of the time taken as a reference. In the following, we are going to refer to the value and utility of genres for the cultural and social history of humanity, by stopping to the genres characteristic to the postmodern era. In this regard, we intend to follow the impact of the digital epistolary in the context of the media globalization, the advantages and disadvantages of the technological progress, the changes in form and content suffered by the “letter” sequence to this evolution.

Another genre that comes to our attention is the comic magazine that can appear to some as an insignificant object, a part of a communist world, invoked in the news debates, only. The original mobility of the comics is situated in its very nature at the intersection of visual and narrative, which gives it the chance to weave bridges over the fields of the folk culture and literature. This may illustrate an alternative, from a cultural insight, where the aesthetic and sociological values coexist. The comics are intellectual challenges for different categories of readers through the new postmodern setting of the values expressed by text and image.

Correspondencias entre indicadores de ingreso a la universidad y los niveles de logro de la competencia diagnóstico en estudiantes de kinesiología
Authors: Escobar Máximo , Sánchez Iván
Published: March 2019

El propósito del presente estudio es asociar, a través del análisis de correspondencia múltiple, los indicadores de ingreso, el rendimiento académico y su vinculación con los niveles de logro de la competencia diagnóstico, que puedan contribuir al estudio de los procesos de enseñanza utilizados por los estudiantes de la carrera de Kinesiología. Para ello, se evaluaron los indicadores de ingreso de los estudiantes de Kinesiología de la Universidad Católica del Maule de la cohorte 2015, y se buscaron relaciones entre los niveles de logro de la competencia diagnóstico, nivel socioeconómico, notas de enseñanza media, prueba de selección universitaria, estudios universitarios, procedencia, autoestima y estilos de aprendizaje, que se asocian a los rendimientos académicos obtenidos, con el propósito de observar eventuales tendencias. Los resultados de los indicadores de ingreso categorizados tradicionalmente no garantizan logros correspondientes a ciclo básico de la carrera. Por su parte, durante el proceso formativo los criterios Bioética, Protocolo y Diagrama son etapas demostrativas para regular a los estudiantes en función de sus desempeños, en tanto aportan a la competencia diagnóstico.

Published: March 2019

Atendiendo la importancia del fenómeno evaluativo y la relevancia de las percepciones estudiantiles, este trabajo explora las valoraciones de estudiantes en Formación Pedagógica respecto del proceso evaluativo del que son objeto. Para tal efecto se confeccionó una escala de actitudes reducida mediante análisis factorial exploratorio. El análisis de los resultados da cuenta de sentimientos de disconformidad y algunas debilidades métricas que, a juicio de los futuros profesores, ponen en cuestión el rol de la evaluación como proveedora de insumos e información de calidad para la toma de decisiones pedagógicas.
La relación familia-institución educativa en enseñanza media: perspectivas de docentes de secundaria
Authors: Vaccotti Rodrigo
Published: March 2019

Las dificultades asociadas a la relación familia-institución educativa aparecen cada vez en mayor medida como objeto de discusión en la bibliografía internacional. El presente estudio se propone indagar acerca de las perspectivas de los docentes de educación secundaria acerca de la relación familia-institución educativa. Para esto se contó con un diseño metodológico de corte cualitativo que incluyó dos focus group entre docentes de secundaria que, al momento del estudio, trabajaban en primer año de ciclo básico. Los datos generados fueron luego estudiados mediante la técnica de análisis de contenido. Entre los principales resultados de la investigación, que supone un primer acercamiento a la temática, se destaca que los docentes consideran fundamental la participación de las familias, pero esta no se da de modo adecuado debido a que las familias muestran muchas dificultades, las instituciones no tienen lineamientos claros para facilitar su acercamiento y la formación de los docentes en este rubro es deficitaria.

Penelitian ini bertujuan untuk mengetahui sifat fisis dan bandgap dari hasil sintesis karbon nanodots (c-dots) kulit bawang merah menggunakan teknik microwave yang kemudian diuji menggunakan alat spektrometer uv-vis. Penelitian ini dilakukan di Laboratorium Fisika-IPB Babakan Dramaga, Bogor, Jawa Barat. Sintesis c-dots dilakukan dengan mengekstrasi kulit bawang merah dan aquades dengan blender, kemudian dimasukan dalam microwave dengan variasi waktu pemanasan selama 5 menit, 10 menit, 15 menit, dan 20 menit. Setelah itu, dilakukan penyaringan agar mendapatkan c-dots yang  homogen. Selanjutnya pengujian bandgap dilakukan dengan alat spektrometer uv-vis dengan rentang panjang gelombang 190-800 nm. Hasil yang diperoleh dari alat spektrometer uv-vis berupa grafik yang menggambarkan hubungan antara nilai absorbansi dan panjang gelombang. Dari percobaan yang telah dilakukan selama 5 kali pengulangan dan perhitungan yang telah dilakukan diperoleh nilai rata-rata bandgap secara berturut-turut sebesar 3,5826 eV, 2,6888 eV, 2,4222 eV, dan 1,11378 eV. Lamanya waktu pemanasan dalam microwave berpengaruh terhadap nilai absorbansi. Dimana nilai absorbansi rata-ratanya adalah 0,76806, 1,21406, 1,3186, 1,74068. Hal Ini menunjukan bahwa semakin besar nilai absorbansi, maka bandgap yang dihasilkannya semakin kecil. Rendahnya bandgap karena energi yang diperlukan untuk eksitasi elektron dari pita valensi ke pita konduksi semakin rendah pula.

Bimbingan dan Konseling (BK) adalah proses interaksi antara konselor dengan konseli baik secara langsung maupun tidak langsung guna membantu konseli agar dapat mengembangkan potensi dirinya atau memecahkan permasalahan yang sedang dihadapi. Proses ini terjadi sangat intesif dan selalu berkembang sesuai dengan keadaan dan kebutuhan konseli. Banyaknya kasus dan jumlah penanganan dirasakan perlu adanya media untuk menyimpan hasil konseling agar dapat digunakan kembali sebagai rujukan konselor dalam menangani kasus yang sama atau memiliki kemiripan. Media yang diperlukan bukan sekedar menyimpan namun dapat digunakan untuk mengambil kembali secara cepat sekaligus mencatatsebagaisebuah basis pengetahuan (Knowledge Base). Berdasarkan kebutuhan tersebut perlu dibuatkan sistem yang dapat menyimpan dan mengambil hasil konseling dengan pendekatan Knowledge Management (KM). Kegiatan BK yang diawali dengan diskusi, memberikan saran atau solusi kepada konseli, merencanakan pemecahan masalah sampai dengan implementasi pemecahan masalah memiliki karakteristik KM dan dikenalsebagai proses SECI (Sosialisation, Externalisation, Combination, Internalization) (Nonaka –Tekeuchi, 1995). Proses inilah yang perlu disimpan dalam bentuk Explicit Knowledge agar dapat dimanfaatkan sebagai rujukan pengetahuan. Hasil penelitian ini adalah pengembangkan sistem informasi Bimbingan dan Konseling yang mengimplementasikan pendekatan Knowledge Management System yang menyelesaikan kebutuhan penyimpanan dan penyajian kembali hasil konseling.
