Authors: Thitiwuthikiat Piyanuch , Jongjitwimol Jirapas , Nuamchit Teonchit
Published: September 2018

Objective: Smoking is a leading risk factor for various diseases including peripheral arterial disease (PAD). PADis a form of cardiovascular disease that affects the blood vessels, resulting in vascular stiffness and occlusion. The ankle-brachial index (ABI) and cardio-ankle vascular index (CAVI) are non-invasive techniques for detection of vascularocclusion and stiffness, respectively. To determine the association between cigarette smoking and peripheral arterialconditions, the ABI and CAVI of smokers and non-smokers were investigated.Material and Method: One hundred and forty one middle-aged participants without underlying diseases wereenrolled, 49 smokers and 92 non-smokers. A questionnaire was developed to collect the demographic information,medical history, and smoking behaviours of the participants, and their ABI and CAVI were measured.Results: Our results showed that the CAVI values of smokers (7.88±1.26) were significantly differed from those ofnon-smokers (7.17±0.94) at p-value <0.001. In addition, age and cigarette smoking were independent factors significantlyrelated to the CAVI values by a multivariate analysis. Likewise, we found a positive relationship between the CAVIvalues and the number of cigarettes smoked per day (r=0.31) and the length of smoking duration (r=0.42) at p-value<0.001. However, the ABI values between smokers and non-smokers were not different.Conclusion: This study demonstrated that age and smoking were significantly related to CAVI, and a greater number ofcigarettes smoked per day and longer smoking duration had positive relationships to CAVI values.

Published: September 2018

Objectives: To compare the work performance of 2004-2013 Prince of Songkla University (PSU) pediatric residencytraining graduates as evaluated by their workplace directors and the graduates self-evaluation.Material and Method: All 78 pediatric graduates from PSU 2004-2013 were located: 52 (66.7%) were in the publicsector and 26 (33.3%) in the private sector. Ten-item performance evaluation questionnaires were sent to both thegraduates and their workplace directors. A rubric scale was used for rating each item from 1 to 10 (1=very poor, 10=excellent). The workplace director was asked to give an open answer for one “outstanding performance” item of the graduates and suggest one “performance that should be improved” item.Results: Forty-five directors (57.7%) and 63 graduates (80.8%) returned their questionnaires. The workplace directors rated the PSU graduates more favorably than the graduates’ self-evaluations in 8 of the 10 items, but without significant differences. The average overall scores for professional performance by both the directors and the graduates were over 8.00, with the highest ratings in ethics/morals in medical care (directors 9.11±0.88 and graduates 9.01±0.92), and the lowest ratings for “concerns in health economics” (directors 8.37±0.93 and graduates 8.04±0.97).Conclusion: Most of our pediatric graduates have achieved career success as most of them were rated by theirdirectors as showing very good performance in their workplaces. The workplace directors tended to rate the PSUgraduates slightly more favorably than the graduates’ own self-evaluations.

Published: September 2018

Objective: To test the effect of bed rest time reduction on back pain and vascular complication in patients with hepatocellular carcinoma after transcatheter arterial chemoembolization (TACE).Material and Method: This study was two-group randomized controlled trial. A total of 54 patients with hepatocellular carcinoma, receiving TACE enrolled from October 2015-November 2016, were purposively selected and randomly assigned equally to receive either 6 hours (the control group) or 3 hours (the experimental group) of bed rest after TACE was achieved. Patients in both groups were evaluated back pain by the pain Numerical Rating Scale and vascular complications by Hematoma Formation and Bleeding Scale. Data were analyzed by chi-square test and Mann-Whitney U-test.Results: The mean total score on back pain in the experimental group was significantly lower than that of the control group at 6 and 8 hours following TACE (p-value< 0.000). No vascular complications was found in both the groups.Conclusion: Reducing bed rest time from 6 hours to 3 hours of patients following TACE can decrease the severity of back pain and has no effect on the incidence of vascular complications.

Authors: Wongsuwan Kotchporn
Published: September 2018

Tuberculosis (TB) can infect any part of the body. Preauricular sinus is a congenital anomaly of the external ear. Infection of the preauricularsinus is mainly caused by bacteria. This is a case report of TB of preauricular abscess which presented with an unresponsive abscess to an antibiotic. TB of preauricular abscess is extremely rare, and assumed to have the same etiology as cutaneous tuberculosis. Treatments are standard anti-TB drugs with excision of preauricular sinus. This case emphasizes the consideration of TB in a preauricular abscess that does not respond toantibiotics, incision and drainage.

Published: September 2018

Objective: The purpose of this study was to determine the effect of the arm-swing exercise on cardio-ankle vascular index (CAVI), ankle-brachial index (ABI), heart rate and blood pressure (BP) in older adults with abnormal CAVI values.Material and Method: Seventeen participants aged 50 or over were asked to do the arm-swing exercise at least 30 minutes a day, at least 3 times per week for 8 weeks. The vascular function parameters, CAVI and ABI, resting heart rate and blood pressure were measured before and after exercising. The comparison of these parameters was performed using statistical analysis.Results: It was shown that the arm-swing exercise could lower both left and right CAVI significantly (left CAVI, pre: 10.0±0.2 vs. post: 9.7±0.2, p-value=0.017 and right CAVI, pre: 10.0±0.2 vs. post: 9.7±0.2, p-value=0.034). Furthermore, the arm-swing exercise also reduced arterial blood pressure and pulse pressure significantly (systolic BP, pre: 141.9±4.3 mmHg vs. post: 130.5±4.8 mmHg, p-value=0.004, diastolic BP, pre: 82.1±1.6 mmHg vs. post: 76.5±1.7 mmHg, p-value=0.003, and pulse pressure, pre: 59.7±3.7 vs. post: 54.0±4.0 mmHg, p-value=0.031). However, the study demonstrated that ABI, resting heart rate and body mass index were not affected by the exercise.Conclusion: This study demonstrated that 8 weeks of the arm-swing exercise could lower systolic and diastolic blood pressure. This simple physical activity could also reduce CAVI values in older adults.

Authors: Youn Myung Soo , Shin Jong Ki , Goh Tae Sik , Son Seung Min , Lee Jung Sub
Published: September 2018

OBJECTIVE

Various minimally invasive techniques have been described for the decompression of lumbar spinal stenosis (LSS). However, few reports have described the results of endoscopic posterior decompression (EPD) with laminectomy performed under local anesthesia. This study aimed to evaluate the clinical and radiological outcomes of EPD performed under local anesthesia in patients with LSS and to compare the procedural outcomes in patients with and without preoperative spondylolisthesis.

METHODS

Fifty patients (28 female and 22 male) who underwent EPD under local anesthesia were included in this study. Patients were assessed before surgery and were followed up with regular outpatient visits (at 1, 3, 6, 12, and 24 months postoperatively). Clinical outcomes were evaluated using the visual analog scale (VAS), Oswestry Disability Index (ODI), and the 36-Item Short Form Survey (SF-36) outcome questionnaire. Radiological outcomes were assessed by measuring lumbar lordosis, disc-wedging angle, percentage of vertebral slippage, and disc height index on plain standing radiographs.

RESULTS

The VAS, ODI, and SF-36 scores were significantly improved at 1 month after surgery compared to the baseline mean values, and the improved scores were maintained over the 2-year follow-up period. Radiological progression was found in 2 patients during the follow-up period. Patients with and without preoperative spondylolisthesis had no significant differences in their clinical and radiological outcomes.

CONCLUSIONS

EPD performed under local anesthesia is effective for LSS treatment. Similar favorable outcomes can be obtained in patients with and without preoperative spondylolisthesis using this approach.
Factors for the acquisition of 10° angular change at the lumbar spine through posterior column osteotomy in adult spinal deformity surgery
Authors: Han Sanghyun , Hyun Seung-Jae , Kim Ki-Jeong , Jahng Tae-Ahn , Kim Hyun-Jib
Published: September 2018

OBJECTIVE

Posterior column osteotomy (PCO) has been known to provide an angular change (AC) of approximately 10° in sagittal plane deformity. However, whether PCO can actually obtain an AC of ≥ 10° depending on the particular level in the lumbar spine and which factors can effect a gain of ≥ 10° AC after PCO remain to be elucidated. The aim of this study was to identify the factors that effect a gain of ≥ 10° AC through PCO by comparing radiographic measurements between an AC group and a control group before and after adult spinal deformity (ASD) surgery.

METHODS

Forty consecutive patients who underwent multilevel PCOs for ASD at a single institution between 2012 and 2016 were included in this study. PCO was performed in 142 disc space levels in the lumbar spine. The authors defined the disc space level that obtained ≥ 10° AC in the sagittal plane by PCO as the AC group and the remaining patients as controls. The modified Pfirrmann grade, surgical level, implementation of the transforaminal lumbar interbody fusion (TLIF), and radiographic measurements were compared between the groups.

RESULTS

There were 67 levels in the AC group and 75 in the control group. Multivariate analysis identified the surgical level at L4–5 (OR 3.802, 95% CI 1.127–12.827, p = 0.031), performing TLIF with PCO (OR 3.303, 95% CI 1.258–8.674, p = 0.015), and a preoperative kyphotic disc space angle (OR 1.397, 95% CI 1.231–1.585, p < 0.001) as the factors that significantly effected ≥ 10° AC in the sagittal plane after PCO.

CONCLUSIONS

In ASD surgery, PCO cannot always achieve ≥ 10° AC in the sagittal plane. The factors that effected ≥ 10° AC in PCO for ASD were surgical level at L4–5, performing TLIF with PCO, and the preoperative kyphotic disc space angle.
Significance of different conformity indices for evaluation of radiosurgery treatment plans for vestibular schwannomas
Authors: Surber Gunnar , Hamm Klaus , Kleinert Gabriele
Published: September 2018

Object. There are various kinds of conformity parameters currently in use, although several of them are limited and reflect only target volume coverage or normal tissue overdosage. Indices are reviewed with the goal of determining those that are most significant for the evaluation of radiosurgery treatment plans for patients with vestibular schwannoma, based on the authors' experience at the Novalis Shaped Beam Surgery Center.

Methods. Fifty-five radiosurgery plans for patients with vestibular schwannomas (VSs) have been evaluated. In this paper the conformation number (CN) and dose-related CN (dCN) are evaluated, and a penalty for underdosed target volumes and overdosed normal tissue is incorporated. A strategy is discussed to apply these indices (CN and dCN) to define the optimal prescription isodose (PI).

For a given radiosurgery treatment plan, permitting partial target underdosage may offer an improvement of the CN. Variations of different conformation indices have been calculated for varying prescription levels—for example, an isodose plan. The resulting graph for the CN is discussed in detail to illustrate its use in defining the optimal PI level. For the 55 cases of VSs reported on, the median CNmax result was 0.78.

Conclusions. It is possible to achieve highly conformal dose distributions with Novalis radiosurgical system. The CN is the parameter of choice when evaluating radiosurgery treatment plans and scoring possible treatment plans. It takes into account both target underdosage and normal tissue overdosage and offers a valuable scoring parameter while avoiding false-perfect scores.
Treatment of trigeminal neuralgia with linear accelerator radiosurgery: initial results
Authors: Chen Joseph C. T. , Girvigian Michael , Greathouse Hugh , Miller Michael , Rahimian Javad
Published: September 2018

Object. Radiosurgery has emerged as an important treatment of trigeminal neuralgia. Substantial advantages have been demonstrated in safety and comfort over other modalities. Radiosurgical treatment of trigeminal neuralgia has been well investigated with gamma knife devices involving fixed cobalt sources. Few reports exist concerning trigeminal neuralgia treated using linear accelerator (LINAC)—based devices. In recent years these devices have reached the level of mechanical precision that is required for such functional treatments. The authors describe their initial experience with radiosurgical treatment of trigeminal neuralgia when using a BrainLAB Novalis LINAC device equipped with the commercially available 4-mm collimator.

Methods. A total of 32 patients were treated in a 12-month period between November 2002 and November 2003. The median patient age was 67 years (range 38–84 years). Facial pain was graded using the Barrow Neurological Institute (BNI) scoring system. All patients' pain was BNI Grade IV or V prior to treatment. Of these patients, 22 were undergoing initial treatment, and 10 were undergoing retreatment for recurrent pain following various treatments including percutaneous procedures, gamma knife surgery (GKS), or microvascular decompression. Two patients had multiple sclerosis. In patients undergoing initial radiosurgery, the most proximal segment of the cisternal portion of the trigeminal nerve received 85 to 90 Gy administered in a 5— or 7—noncoplanar arc single-isocenter plan with a 4-mm circular collimator. In patients undergoing repeated radiosurgery, the target received 60 Gy.

Overall good and excellent results (BNI Grade I, II, or III) were achieved in 25 (78%) of 32 patients. The median time to pain relief was 6 weeks. Fair results (improvement in pain with BNI Grade IV) were achieved in three patients (9%), and poor results (no improvement in pain and BNI Grade IV or V) were seen in four (13%). Two patients demonstrated new trigeminal dysfunction following treatment. No other complications occurred.

Conclusions. High-precision imaging and LINAC instrumentation have allowed for treatment of trigeminal neuralgia with results and safety comparable to those achieved using GKS. Linear accelerator—based radiosurgery with the Novalis device is a safe and effective method of managing trigeminal neuralgia and may become the preferred means at centers where the technology is available.

Authors: Solberg Timothy D. , Goetsch Steven J. , Selch Michael T. , Melega William , Lacan Goran , DeSalles Antonio A. F.
Published: September 2018

Object. The purpose of this work was to investigate the targeting and dosimetric characteristics of a linear accelerator (LINAC) system dedicated for stereotactic radiosurgery compared with those of a commercial gamma knife (GK) unit.

Methods. A phantom was rigidly affixed within a Leksell stereotactic frame and axial computerized tomography scans were obtained using an appropriate stereotactic localization device. Treatment plans were performed, film was inserted into a recessed area, and the phantom was positioned and treated according to each treatment plan. In the case of the LINAC system, four 140° arcs, spanning ± 60° of couch rotation, were used. In the case of the GK unit, all 201 sources were left unplugged. Radiation was delivered using 3- and 8-mm LINAC collimators and 4- and 8-mm collimators of the GK unit. Targeting ability was investigated independently on the dedicated LINAC by using a primate model.

Measured 50% spot widths for multisource, single-shot radiation exceeded nominal values in all cases by 38 to 70% for the GK unit and 11 to 33% for the LINAC system. Measured offsets were indicative of submillimeter targeting precision on both devices. In primate studies, the appearance of an magnetic resonance imaging—enhancing lesion coincided with the intended target.

Conclusions. Radiosurgery performed using the 3-mm collimator of the dedicated LINAC exhibited characteristics that compared favorably with those of a dedicated GK unit. Overall targeting accuracy in the submillimeter range can be achieved, and dose distributions with sharp falloff can be expected for both devices.
Dose fractionation in stereotactic radiotherapy for parasellar meningiomas: radiobiological considerations of efficacy and optic nerve tolerance
Authors: Shrieve Dennis C. , Hazard Lisa , Boucher Kenneth , Jensen Randy L.
Published: September 2018

Object. Benign meningiomas have been shown to be equally well controlled with single-dose radiosurgery (15 Gy) and fractionated doses of 54 Gy in 30 fractions after adequate follow up. For a subset of patients with meningioma, the optic apparatus is dose limiting when considering single-dose stereotactic radiosurgery, with tolerance estimated to be 8 to 10 Gy. Recently, hypofractionated regimens have been used to treat benign meningiomas with a small number of fractions. An analysis of the expected efficacy of hypofractionation compared with the estimated optic tolerance to fractionated radiotherapy was undertaken.

Methods. Using the assumption that 15 Gy in one fraction and 54 Gy in 30 fractions are isoeffective for control of benign meningioma, an α/β for meningioma is calculated to be 3.28 Gy. Invoking a 10% error for these doses (15 Gy ± 10% is equivalent to 54 Gy ± 10%) results in upper and lower limits of the estimate for α/β of 3.85 Gy and 2.7 Gy. Using these estimates, isoeffect curves for control of meningioma were constructed for fraction numbers of one to 45. Best estimates of optic nerve/chiasm tolerance to single doses of radiation are 8 to 10 Gy, with the reported incidence of optic neuropathy increasing significantly at higher doses. This is consistent with the optic ret model, which also predicts for optic tolerance following fractionated radiotherapy. Comparison of optic tolerance and estimates of efficacious doses at fraction numbers between one and 30 were made. Statistical estimates of patient numbers and duration of follow up required to rule out optic neuropathy following radiotherapy were made. Single doses of radiation required to treat benign meningioma optimally (13.5–16.5 Gy) clearly exceed the estimated and reported clinical tolerance of the optic nerves and chiasm. The application of equivalent biological doses in a small number of fractions continues to exceed optic tolerance until at least 25 fractions are applied.

Conclusions. The use of small numbers of fractions to treat patients with meningioma when portions of optic nerve or chiasm receive full dose may result in undertreatment of the tumor and/or exceeding optic nerve tolerance. In such cases standard fractionation is recommended. Ruling out a low, yet unacceptable, risk of optic neuropathy may require the close study of many patients with long-term follow-up evaluation.

The objectives of the village planning arranged for the village development plan can be discussed in the village development consultation forum. In this Forum the village development plan is matured, so it becomes the Village Development Plan. The preparation of village development planning can not be carried out properly, without complete data and information either in the implementation of village government, organization and governance of village administration, village finance, village profile and other information related to governance and community empowerment. The three villages that were used as research mapping object in Kampar sub-district Tambang were Tarai build village, Rimbo Panjang village and Tambang village. Village development planning in the three sample villages appears to be underdeveloped by complete data and information, and this has a major impact on the Village Mid Term Development Plan (RPJMDesa) and the Government-Village Action Plan (RKP -Desa) which guides development implementation in the countryside

Prototype of Batam as an industrial city in Indonesia with a variety of large factories has impacts on the environment. For example, waste and air pollution. AMDAL (Environmental Impact Assessment) issue becomes an urgent issue for Batam government which involves the role of Bapedalda Batam. The data of Batam Bapedalda from 2011 to 2015 showed the improvement of AMDAL. This study aims atanalyzing the policies and programs of Batam Environmental Impact Management Agency (Bapedalda) to the increase of AMDAL percentage. Method of collecting datawas done by interview, observation and documentation. Technique of selecting informant was purposive sampling, data analysis technique was done by data reduction, data presentation and conclusion. For large-scale industrial areas such as Batamindo, Kabil, Panbil the implementation of AMDAL have been effective but for the coastal area is still less effective because of investor low awareness. There are three things to increasethe percentage of AMDAL: (1) increasing the investor requirement of voluntary from company, (2) effort in socialization context, door to door service, (3) public awarenessby applying law enforcement.

Analisis January Effect Pada Saham Astra Internasional (ASII) Di Bursa Efek Indonesia Pada Periode 2005 - 2015
Authors: Kiky Andreas
Published: September 2018

In Stock Market our goal is pursue optimum wealth by appreciation of our Stocks. Stock price fluctuate over time as nobody can predict. In this research our aim is to observe the market anomaly that might be happened as the investor behave. We will examine January Effect as Keim observe in 1986 in Indonesia Stock Exchange. Also we can also examine Efficient Market Hypothesis as the result from anomaly and abnormal return that founded in this research. If we can find the market anomaly perhaps we can map the market seasonal trend as the past data recorded. If this anomaly exists we could suggest investor to invest their money as the anomaly data shown. Then investor could gain optimum wealth base on this information. Purpose of this paper is to examine market anomaly and does it exist in Indonesia market? Our main objective is to predict the market movement base on seasonal or anomaly pattern that has been found in previous research. We use CAPM to measure Expected Return of Asset and we use ASII stock price to measure the return of the stock. Our finding is far from our expectation. We expect to find January Effect here but unfortunately we found another anomaly that happen in May and October. Our research suggest that we should cautious for this investor behavior because they seem react as the new information or news appear

Published: September 2018

In this project, we demonstrated how to improve transfer rate when transfering data from a notebook installed FreeBSD operating system to another notebook installed Windows 8 operating system. The method which we used was with customizing the kernel on FreeBSD. Before we customized the kernel, we calculated the average time of the transfer speed with its default kernel. After we got the average time, then we customized its kernel and calculated the average time after we installed the custom kernel. At the end we got faster average time with the customized kernel and the performance better.

Implementasi Probability Impact Matriks (PIM) Untuk Mengidentifikasi Kemungkinan dan Dampak Risiko Proyek
Authors: Sufa'atin Sufa'atin
Published: September 2018

One of the obstacles in project construction is that the project is experiencing delays. The delay is influenced by several factors including the absence of risk recording, the unavoidability of the opportunities and the impact of risks that arise in the project and its handling, and the neglected risks that may disrupt the project. Project risk is the cumulative effect of an uncertain event opportunity, which affects the project objectives. Several methods can be used to handle the occurrence of project risk, one of the methods used to perform a risk assessment is the Probability Impact Matrix (PIM). PIM is a method that can be used to analyze risk qualitatively based on probability and its impact. By using the PIM method, some of the opportunities and impacts of risks that may arise in the project can be identified. In addition, the PIM method can minimize the risks that arise in the project and quickly resolve the risks.

Authors: Tambunan Bosman , Raharjo Willy Sudiarto , Purwadi Joko
Published: September 2018

Teknologi Internet saat ini tidak lepas dari banyak masalah ataupun celah keamanan. Banyaknya celah keamanan ini dimanfaatkan oleh orang yang tidak berhak untuk mencuri data-data penting. Kasus serangan terjadi karena pihak yang diserang juga tidak menyadari pentingnya keamanan jaringan untuk diterapkan pada sistem yang dimiliki. Honeypot yang dipadu dengan IPS menggunakan PSAD dan Fwsnort memberikan solusi untuk masalah tersebut. IPS berfungsi sebagai sistem yang bekerja memantau aktivitas jaringan yang melalui sistem IPS pada mode inline dan memblokir alamat IP yang mencurigakan setelah data stream dicocokan dengan signature yang ada, sedangkan Honeypot bekerja untuk mengetahui aktivitas penyerang dan semua aktivitas yang menuju pada honeypot dianggap mencurigakan. Hasil penelitian menunjukkan bahwa kemampuan Honeypot yang dipadu dengan IPS PSAD dan Fwsnort dapat saling melengkapi dalam mendeteksi serangan yang tidak diketahui oleh sistem IPS. Sistem ini juga menghasilkan log data yang dapat digunakan oleh administrator dalam menanggulangi serangan yang terjadi.

Pengukuran Beban Komputasi Algoritma Dijkstra, A*, dan Floyd-Warshall pada Perangkat Android
Authors: Djojo Michael Alexander , Karyono Karyono
Published: September 2018

Perkembangan teknologi di bidang komunikasi menciptakan berbagai kemudahan bagi pengguna untuk melakukan pertukaran informasi tanpa mengenal jarak secara geografis. Pada jaringan komunikasi, pertukaran informasi memerlukan pengaturan rute sehingga dicapai jalur terpendek untuk mengoptimalkan proses pengiriman data. Penelitian untuk mencari algoritma jalur terpendek masih terus dilakukan. Penelitian ini membandingkan algoritma Dijkstra, A*, dan Floyd-Warshall dari sisi waktu, beban komputasi dan penggunaan memori. Topologi yang digunakan dalam penelitian adalah topologi jaringan mesh karena dapat mewakili kondisi nyata. Aplikasi berbasis Android dapat digunakan sebagai simulator untuk memetakan vertice dan edge ke dalam kumpulan node dan channel yang saling berhubungan. Kompleksitas komputasi dalam pencarian jalur terpendek menjadi hal yang penting karena terdapat keterbatasan prosesor dan memori. Kompleksitas rute akan sebanding dengan skala jaringan mesh. Dari simulasi diperoleh nilai beban komputasi dan waktu simulasi yang sebanding dengan fungsi kuadrat jumlah simpul untuk ketiga algoritma tersebut. Hasil pengujian menunjukkan algoritma A* memiliki beban komputasi dan waktu simulasi yang paling kecil dibandingkan algoritma Dijkstra dan Floyd-Warshall tanpa mempengaruhi hasil pencarian rute terpendek. Hal ini disebabkan algoritma A* melakukan operasi pencarian dengan memanfaatkan nilai heuristik terhadap simpul tujuan, sehingga tidak semua simpul dilakukan pengecekan. Namun algoritma Dijkstra paling unggul dalam penggunaan memori. Floyd-Warshall menghasilkan nilai kompleksitas yang buruk pada proses pancarian jalur, semua data bobot kanal akan ditampung ke dalam matriks dua dimensi lalu diproses menggunakan operasi perulangan yang bertingkat.
