Состояние централизованных систем водоснабжения и водоотведения значительного числа городов и поселений России с точки зрения их износа и надежности вызывает тревогу. Проблемы, которые на сегодняшний день существуют в сфере жилищно-коммунального хозяйства, во многом обусловлены недостаточностью ресурсов, имеющихся у субъектов Российской Федерации и органов местного самоуправления, значительным сокращением фундаментальных и прикладных научных работ в этой сфере. Приведена информация о проблемах и возможных вариантах ее решения, о задачах научных исследований, обсуждаемых Научным советом Российской академии архитектуры и строительных наук «Инженерные системы водопользования», в новый состав которого вошли известные ученые – специалисты в области систем водоснабжения и водоотведения. Отмечено, что в последние годы из-за недофинансирования в сфере коммунального хозяйства происходит опережающий износ сооружений водоподготовки и трубопроводов систем водоотведения, подачи и распределения воды. Показано, что инновационные разработки российских ученых используются крайне незначительно. Этому способствовало то, что до настоящего времени организациям жилищно-коммунального хозяйства более выгодно приобретение готовой зарубежной продукции, нежели участие в развитии собственного производства.

The state of public water supply and wastewater disposal systems in a considerable number of cities and towns in Russia in terms of their wear and tear and reliability causes alarm. The problems that exist today in the field of housing and public utilities are largely due to the lack of resources available with the constituent entities of the Russian Federation and local governments, and significant reduction in fundamental and applied scientific work in this area. Information is provided on the problems and possible solutions, on the tasks of scientific research discussed by «Engineering Systems of Water Use», the Scientific Council of the Russian Academy of Architecture and Building Sciences, the new composition of which included well-known scientists – experts in the field of water supply and wastewater disposal systems. It is noted that in recent years, due to underfunding in the field of public utilities, an advanced wear of water treatment facilities and pipelines of wastewater disposal systems, water supply and distribution systems occurs. It is shown that the innovative developments of Russian scientists have been hardly used. This was facilitated by the fact that until now it is more profitable for housing and public utilities companies to purchase finished foreign products than to participate in the development of their own production.

Statistical modeling of V
th distribution in ovonic threshold switches based on physical switching models
Authors: Yokogawa Shinji
Published: January 2023

This paper discusses the statistical modeling of the V
th distribution of an ovonic threshold switch, an integral component of high-speed, high-capacity storage-class memory. A distribution function that explains the V
th variation and a method for estimating and judging it is proposed based on three representative switching mechanisms—thermal runaway model, physically based electrical model, and two-state defect model. We examined the relationship between the segment V
th distribution and V
th minimum distribution is examined by considering chip-level scaling in Monte Carlo simulations and analytical analysis of the distribution function. The latter distribution approaches the Weibull distribution; however, its convergence speed differs.
Influence of substrate impurity concentration on sub-threshold swing of Si n-channel MOSFETs at cryogenic temperatures down to 4 K
Authors: Kang Min-Soo , Sumita Kei , Oka Hiroshi , Mori Takahiro , Toprasertpong Kasidit , Takenaka Mitsuru , Takagi Shinichi
Published: January 2023

The sub-threshold swing (SS) of Si n-MOSFETs is experimentally and systematically evaluated in a temperature range of 4–300 K with varying the substrate impurity concentration (N
sub) from ~1016 to ~1018 cm−3, to obtain a physical understanding of SS at cryogenic temperatures. It is clarified that the temperature and drain current dependencies of SS in n-MOSFETs are well represented by a model composed of mobile tail states and localized interface states, irrespective of N
sub. The densities of these states are found to increase with increasing N
sub. A physical origin of band tail states is studied by experimentally examining the impact of substrate bias on these states, which can separate the effects of the N
sub and the surface electric field. It has been clarified, as a result, that the band tail states can be explained by the impurity-induced model.
A 24 V to 1 V integrated dual-charging path dual-inductor hybrid converter for improved step-up load transient response
Authors: Nishijima Kazuya , Umeki Toma , Miyaji Kousuke
Published: January 2023

This paper proposes a dual-charging-path dual-inductor hybrid converter that can charge two inductors simultaneously to improve the step-up load transient response. The proposed scheme only introduces one additional switch and capacitor to form a dual charging path during step-up load transient response. All power switches are integrated using 5 V transistors with 0.25 μm HV BCD process. Using type-3 PWM control combined with a fast load transient detector, simulation results show that the proposed circuit achieves 55.4% voltage drop and 23.6% recovery time reduction compared to the conventional DIH converter for load transient step from 20 mA to 4 A.
Power device breakdown mechanism and characterization: review and perspective
Authors: Zhang Ruizhe , Zhang Yuhao
Published: January 2023

Breakdown voltage (BV) is arguably one of the most critical parameters for power devices. While avalanche breakdown is prevailing in silicon and silicon carbide devices, it is lacking in many wide bandgap (WBG) and ultra-wide bandgap (UWBG) devices, such as the gallium nitride high electron mobility transistor and existing UWBG devices, due to the deployment of junction-less device structures or the inherent material challenges of forming p-n junctions. This paper starts with a survey of avalanche and non-avalanche breakdown mechanisms in WBG and UWBG devices, followed by the distinction between the static and dynamic BV. Various BV characterization methods, including the static and pulse I–V sweep, unclamped and clamped inductive switching, as well as continuous overvoltage switching, are comparatively introduced. The device physics behind the time- and frequency-dependent BV as well as the enabling device structures for avalanche breakdown are also discussed. The paper concludes by identifying research gaps for understanding the breakdown of WBG and UWBG power devices.

Published: January 2023

Aiming to understand the bending characteristics of a MgB2 thin-film wire and utilize the wire in the design of superconducting magnets, we examined the degradation of critical current density J
c due to bending. Six short MgB2 thin-film wires with a thickness of 1 μm were prepared under the same deposition conditions. They were bent in different radii, and their J
c were compared. The allowable bending radius at which J
c does not degrade was 25.0 mm. As for MgB2 thin-film wires, thickening the film effectively increases the engineering critical current density J
e. On the basis of material mechanics, the allowable bending radius was estimated to be 25.5 mm when the film thickness increased to 10 μm. The allowable bending radius of the MgB2 thin-film wire is sufficiently smaller than the radius of a typical superconducting coil, so it is not considered to be a barrier to fabricating a coil with the wire.
Estimation of electric field distribution of Hermstein’s glow corona discharge by spectral image processing
Authors: Sasamoto Ryo , Shirouzu Akihiro , Orii Hideaki , Hanai Masahiro , Shinohara Masanori
Published: January 2023

We present a spectral image processing method for estimating the distribution of the reduced electric field E/N for Hermstein’s glow corona discharge. This method analyzes spectral images of the discharge taken by an intensified charge-coupled device camera with ultra-narrow band pass filters at the pixel level. The method requires a shorter measurement time than optical emission spectroscopy and can reveal finer details of the spatial distribution. Experiments showed that the E/N of discharge at the tip of the electrode locally increases with an increase in the applied voltage. In particular, E/N at the tip of the electrode reaches a high value just before breakdown. Based on the maximum acquired values, the breakdown of discharge is estimated to occur when E/N ≥ 270 × 10−21–340 × 10−21 V m2. This study is expected to contribute to monitoring the discharge state of electrical equipment to prevent breakdown and ensure safety.
Evaluation of terpene-based hydrophobic deep eutectic solvents as skin permeation enhancers
Authors: Araki Yuta , Hamada Yuma , Imamura Norika , Yamasaka Koki , Sakuragi Mina
Published: January 2023

We investigated whether carboxylic acid-terpene-based deep eutectic solvents (DESs) can be used as skin permeation enhancers. We performed transdermal experiments, and their results showed that DESs with longer hydrocarbon chains can enhance the skin permeability of hydrophilic fluorescein sodium and hydrophobic meloxicam. Additionally, all DESs could improve the skin permeability of poorly soluble resveratrol. Subsequently, we evaluated the stratum corneum’s structural transition after applying DESs. The results showed that the l-menthol-based DESs with longer hydrocarbon chains disrupt lipid layers more than those with shorter hydrocarbon chains. Thymol-based DES extracted the lipids in the stratum corneum and permeated the corneocytes. Transepidermal water loss measurements showed that l-menthol-based DESs with longer hydrocarbon chains and thymol-based DESs damage skin as they disturb the inner parts of stratum corneum lipids. Overall, we concluded that DESs with longer hydrocarbon chains can be used as skin permeation enhancers for various drugs by reducing skin irritation.

Published: January 2023

In recent years, softening a ferroelectric polymer for wearable tactile electronics has been challenging because of its high robustness and crystallinity. In this study, a functional piezoelectric material system was fabricated by optimizing the blend ratio of a copolymer of PMMA-PBA, which is an amorphous polymer, and a ferroelectric polymer P(VDF-TrFE). The stretchable film was able to extend it up to maximum 400%. By fabricating a capacitor-type device combined with a conductive polymer, we demonstrated the possibility of applying it to a stretchable sensor.

Authors: Lü Cheng , Tang Shuai , Wu Jin-Lei , Pei Yanbo , Jiang Yongyuan
Published: January 2023

By utilizing an array of cascaded Helmholtz resonators (HRs) with high transmittance and linear phase response, a broadband achromatic acoustic lens (AAL) is realized and verified in numerical simulations as well as experimental measurements. The focal length is independent of the incident frequencies from 2000 to 4500 Hz owing to the phase compensation provided by HR arrays. The FWHM of the focal point could remain approximately half of the wavelength within the operating band, showing an excellent performance of the lens. This work enriches the design of AAL, which may have potential applications in biomedical imaging and acoustic detection.

Authors: Faircloth Johnnie , Vasylyeva Tetyana L. , Cabanas Ma Cristine , Sankoorikkal Nikita
Published: January 2023

Multicystic dysplastic kidney (MCDK) is a common congenital condition in neonates caused by the abnormal formation of renal tissue into multiple fluid-filled cysts that are often dysplastic, affecting kidney function. [1] It has an incidence of 1:4300 live births and is more common in males than females, most often presenting unilaterally with a slightly higher percentage of cases affecting the left kidney. We present a case of a monochorionic diamniotic twin female, with twin A having multicystic dysplastic kidneys on the left and twin B having agenesis of the right kidney. Documented cases involving twins rarely involve both twins or, if so, infrequently in the contralateral kidneys of each twin, highlighting the complexity of renal development in utero.

The concept and methodology of performance assessment in sports dance
Authors: Varnacova Eleonora , Gutu Zoia
Published: January 2023

In the given article, a concept of performance evaluation in sports dance is founded. This concept focuses on two interconnected dimensions: the approach related to the evaluation theory and the approach related to specific indicators of choreography, in the given case, of sports dance: rhythm, posture, technical interpretation, presentation/ musicality. The article specifies the particularities of the evaluation of artistic performances, which differ from cognitive/ academic ones, first of all, by criteria and typology of artistic/choreographic products. At the same time, performance evaluation rules are formulated through the "Skating" system - a method of accumulating points that gives priority to the ”majority” and ”general performance”. Also in this article the advantages and disadvantages of this method are deduced.

Published: January 2023

This study aims to describe the impact of learning loss on students at universities in Indonesia who are often overlooked in educational discourse during the COVID-19 pandemic. Learning loss is only considered to have an impact on students at school. Whereas learning loss is a global phenomenon, which threatens all students around the world, both in schools and universities. The research method used is descriptive research method with a case study approach. Data were collected through questionnaires, interviews, document analysis, literature study, and observation. Then the data was analyzed adopting interactive analysis from Miles and Huberman. The results of the study indicate that learning loss that occurs in students affects student readiness, not only in the process of achieving competence and learning objectives at university, but also students' readiness to enter the world of work. As many as 87% of students are worried about whether they can get a job after graduating during the COVID-19 period. This concern is reinforced by the phenomenon: around 88% or 9 out of 10 companies are affected by the pandemic in Indonesia. Unemployment is open as much as 3.5 million to 8.5 million people throughout 2020, while Indonesia's economic growth in 2020 is minus 2.07 %.

Introduction: Late pregnancies are a hot topic for both women and perinatal health workers because of their increasing increase. In the elderly primiparous pregnancy, pregnancy has always preoccupied birth attendants for a long time because high-risk pregnancy is the one that is associated with certain risk factors that can hinder its normal evolution. Objective: Study childbirth in the elderly primiparous at the Reference Health Center of Commune V of the District of Bamako. Materials and Methods: This was a retrospective and analytical case/control study (1 case for 2 controls), from 1January 2019 to 31 December 2021.It had covered all deliveries recorded in the ward. Results: The frequency of delivery in the elderly primiparous was 0.36%. The most educated elderly primiparous accounted for 73.3% (p=0,000; OR= 2.014; 95% CI = [0.006-0.31]). Dystocia was the most common obstetric complication (p=0.13; OR= 0.69; 95% CI = [0.42-1.12]). Caesarean delivery accounted for 77.1% in cases versus 49% in controls (p=0.000; OR= 0.28; 95% CI = [0.170.48]). Apgar's score was greater than or equal to 8 in 90.5% of cases versus 82.4% of controls. We have not recorded any maternal deaths. Conclusion: Pregnancy and childbirth in the elderly primiparous are risk situations in some cases. Childbirth in the elderly primipare requires a skill that can detect and prevent morbid situations and allow adequate care.

Published: January 2023

Introduction: Ankylosing spondylitis or rheumatic pelvispondylitis is a chronic inflammatory rheumatism characterized by an axial localization predominantly in the spine and sacroiliac joints, an involvement of the entheses and a tendency to bone ankylosis by ossification of these entheses. We report an observation of right lower limb lymphedema associated with ankylosing spondylitis. Observation: This was a 63-year-old patient with a history of inflammatory rheumatism (his older sister) and osteoporosis (his mother), He was diagnosed with ankylosing spondylitis based on enthesis involvement (bilateral tilted gluteal pain and low inflammatory back pain) with a positive HLA-B27 antigen by the 8-point Amor criteria for spondyloarthritis (right unilateral sacroiliitis, low inflammatory back pain, bilateral tilted gluteal pain, HLA-B27+ and NSAID sensitivity). The unilateral lymphedema with positive Stemmer's sign affected the lower 2/3 of the right lower limb. It occurred one year after the onset of ankylosing spondylitis. The echo-Doppler scan showed no signs of thrombosis or venous infiltration of the lower limbs, and diffuse infiltration of the subcutaneous tissue of the right leg without inflammatory character. Treatment of ankylosing spondylitis gradually improved the lymphedema. Conclusion: Lymphedema is a rare complication of ankylosing spondylitis. Dermatologists should be alert to early swelling of the extremities in patients with ankylosing spondylitis so as not to delay specific multidisciplinary treatment and measures to avoid irreversible lymphatic damage.

Currently, many studies address the relationship between function and brain waves with medical diseases, psychological disorders, or human capacity to various subjects. One of them is by generating individual potentials using brainwaves. Alpha and theta waves in the learning process can be attributed to this brainwave therapy since these waves can improve brain performance to concentrate more on improving memory power and also intelligence. Alpha and theta waves can be listened to in everyday life, in the form of audio from the sound of music. This research is purely experimental (true experimental design) with a randomized pretest- posttest control group design research design. The subject of the study was a student of the Faculty of Medicine Class of 2019. The test method used is a method of measuring brain concentration power using alpha wave audio equipment and theta wave audio. The respondents in this study were 139 students. It was seen that there was an improvement in test results (brain concentration power) before and after exposure to alpha wave audio, where test scores of 9 (better category) increased from 18 students (12.95%) to 97 students (69.6%). The test results (Brain concentration) before and after exposure to theta wave audio showed an increase, from 20 students (14.38%) to 29 students (20.86%) on test scores of 10 (excellent category). From the T-test, significant results were found with a p-value of < 0.05, which is 0.000, which means that there is a difference before and after exposure to alpha waves and theta waves to brain concentration power. The conclusion obtained from this study is that there is an influence of alpha wave audio and theta wave audio on brain concentration power in students of the Faculty of Medicine, Sam Ratulangi University Class of 2019.

Background: The most common causes of prenatal morbidity and death in Bangladesh are eclampsia and severe preeclampsia or toxemia (PET). Obstetricians and anesthesiologists have complex challenges while dealing with this condition. Despite the improved result of spinal anesthesia over general anesthesia, general anesthesia is still routinely used for emergency LUCS in underdeveloped nations. More and more people in industrialized nations, such as the United Kingdom and the United States, recognize spinal anesthesia for its safety. Objective: In this study our main aim is to evaluate the efficacy of the Spinal Anesthesia during Emergency Cesarean Section for Severe Preeclampsia and Eclampsia Patients. Method: This cross-sectional study was carried out at tertiary medical hospital from January 2020 to January 2021. Total 200 cases of severe PET (n=110) and eclampsia (n=100) patients were selected by subarachnoid block for emergency LUCS. Each patient was given magsulph as prophylactic or maintenance dose and judiciously preloaded by crystalloid fluid. Results: Most of the patients belong to 31-40 years age group, 55% and 95.8% cases were multigravida. In severe PET group, intraoperative hypotension was observed in 32% cases and postoperative period hypotension was observed in 8% cases. Whereas preeclampsia group, intraoperative hypotension was observed in 31% cases and postoperative period hypotension was observed in 9% cases. In addition, maternal morbidity where acute renal failure seen in 5%, syndrome 7%, DIC 7%, abruptio placentae 12%, pulmonary edema 4%, septicemia 13%, PPH 10% and postpartum eclampsia 15%.In severe PET group, 21% cases transferred to eclampsia ward, followed by 9% shifted to ICU, 1% case was expired. Whereas, in preeclampsia group 20% cases transferred to eclampsia ward, followed by 8% shifted to ICU, 2% case was expired. In eclamptic group 7% cases were transferred to NCU, whereas 8% had PET. Neonatal mortality was observed in 3% cases. p value was found 0.000 which is very highly significant. Conclusion: With close monitoring of perioperative events, spinal anesthesia may be used as a safe alternative technique to GA or epidural in severe preeclampsia and eclampsia, even in cases of altered consciousness or restlessness in the presence of an expert and skilled anesthesiologist, reducing perioperative maternal and neonatal morbidity and mortality.

Bár már több kutató is foglalkozott az úgynevezett inquisitio malefactorum intézményével, a rendszerezett ismeretek hiánya és a kibontott források korlátozott száma miatt elkerülhetetlen egy olyan tanulmány, amely erre az intézményre összpontosít. Ebben a tanulmányban, miután felvázoltam magát az eljárást, megkísérlem, hogy megfelelő definíciót adjak, és kijelöljem az inquisitio malefactorum joghatóságának határait, valamint foglalkozom olyan vitás kérdésekkel, mint az eljárást végző személyek, valamint az eljárás helye és ideje. Összefoglalva megállapíthatjuk, hogy az inquisitio malefactorum valójában az inkvizítori büntetőeljárás egy formája, amely a 17. században a sedes iudiciariae-vel párhuzamosan működött, és nem vált azok előkészítő eljárásává, ahogyan azt a kutatók korábban feltételezték.
Az egyetemes katolicizmus és az anyanyelvű népi vallásosság szerepe(i) a moldvai magyarság történetében
Authors: Iancu Laura
Published: January 2023

A tanulmány alapvetése szerint a Vatikán keleti egyházpolitikája és a moldvai katolicizmus története szorosan összefonódik. Az ortodox Moldvában a katolikus egyház nem pusztán, mint vallási intézmény, hanem mint politikai és kulturális erő volt jelen és vett részt a nyugati, latin szellemiség moldvai meghonosításában. Minthogy a katolikus lakosság különféle etnikumokból (szászok, lengyelek, magyarok) állt, a Kelet–Nyugat (földrajzi) határán intézményesült, maga is idegen (nyugati) egyház az idegen etnikumok államalkotó nemzethez való asszimilálását is segítette, akarva-akaratlanul. Ebben a környezetben a moldvai katolikus magyarság etnikai megmaradása részben annak köszönhető, hogy a Vatikán figyelme nem elsősorban a hívekre irányult, hanem a misszió fenntartására, majd az egyház teljes értékű legalizálására. A vallásvezetői szerepet betöltő anyanyelvű kántorok működése, az anyanyelvű népi vallásosság és a vallásos folklór jelentősen hozzájárult ahhoz, hogy a hívek végül hűséget tanúsítottak az egyház iránt, és katolikus hitüket megőrizték. A tanulmány e mélyen összetett egyház- és vallástörténet néhány kérdését taglalja részletesebben.

Praktik dokter yang melakukan terapi kepada keluarga sendiri masih menjadi perdebatan hingga saat ini. Indonesia belum mengeluarkan hukum terkait hal ini dan belum ada tinjauan etika yang membahas terkait permasalahan tersebut. Mengobati keluarga sendiri dianggap tidak profesional dan bertentangan dengan KODEKI (Kode Etik Kedokteran Indonesia) 2012 Pasal 2, yaitu dokter dituntut untuk menjadi profesional secara independen. Berbagai alasan yang menyebabkan dokter tidak boleh mengobati anggota keluarganya yaitu objektivitas bisa terkompromi, pasien merasa sungkan mengemukakan informasi, otonomi pasien terkompromi, dan prinsip informed consent bisa terabaikan. Situasi khusus yang memperbolehkan dokter melakukan terapi kepada keluarga yaitu penyakit tergolong minor dan emergensi. Karena berbagai pergumulan muncul dari kalangan dokter akan praktik mengobati keluarganya sendiri, oleh karena itu tinjauan ini merangkum berbagai alasan apakah dokter diperbolehkan melakukan terapi terhadap keluarga sendiri dan situasi khusus yang memperbolehkannya.

Dermatosis neutrofilik adalah sebuah kelompok penyakit inflamasi kulit dengan predominasi infiltrat neutrofil yang steril dan memiliki manifestasi klinis yang berbeda-beda. Tertundanya diagnosis dan tatalaksana dapat menyebabkan morbiditas yang signifikan bahkan kematian. Tinjauan pustaka ini membahas manifestasi klinis, pemeriksaan penunjang, tata laksana, dan komplikasi dermatosis neutrofilik yang relatif umum ditemui, yaitu sindrom Sweet, pioderma gangrenosum, dermatosis pustular subkorneal, dan penyakit Behcet. Pilihan terapi umumnya bersifat imunosupresif dan perlu disesuaikan dengan diagnosis; pada kebanyakan kasus, kortikosteroid adalah terapi lini pertama diikuti agen imunosupresan lainnya seperti kolkisin dan siklosporin sampai agen biologik yang memiliki target spesifik. Pengenalan akan gambaran klinis dan tatalaksana yang adekuat wajib dimiliki oleh dokter spesialis dermatologi dan venereologi untuk menegakkan diagnosis sedini mungkin dan mencegah komplikasi.

Published: January 2023

Prevalensi penyakit infeksi yang disebabkan oleh Soil Transmitted Helminths (STH) mencapai 60-80% dari penduduk Indonesia. Infeksi STH ditularkan melalui kotoran atau feses manusia yang telah terinfeksi telur cacing dan mengkontaminasi tanah. Telur yang terkontaminasi akan menempel pada sayuran yang tumbuhnya dekat dengan tanah seperti selada yang disajikan secara mentah. Sayur selada sering terkontaminasi oleh parasit usus seperti STH karena telur yang menempel pada daun selada. Studi ini bertujuan untuk mengetahui ada tidaknya kontaminasi telur cacing pada sayur selada selama 5 tahun terakhir ini. Metode yang digunakan pada studi ini dengan cara pencarian artikel dalam basis eletronik melalui internet dengan menggunakan Google scholar, Pubmed, dan Proquest. Hasil didapatkan bahwa masih ada kontaminasi STH pada sayur selada dan jenis cacing paling banyak mengkontaminasi adalah Ascaris lumbricoides. Faktor yang mempengaruhi kontaminasi pada selada adalah teknik pencucian yang kurang bersih, pemakaian pupuk organik yang berasal dari kotoran hewan, dan sistem irigasi untuk menyiram sayuran yang telah terkontaminasi.

Seiring dengan bertambahnya usia seseorang, kulit sebagai jaringan terluar dari tubuh manusia akan memberikan gambaran paling terlihat dari proses penuaan. Penuaan kulit dipengaruhi oleh dua faktor yaitu faktor intrinsik dan faktor ekstrinsik. Faktor intrinsik terjadi secara alamiah dan berkaitan dengan proses degenerasi seluler. Faktor ekstrinsik berkaitan dengan pajanan sinar matahari, rokok, dan polusi udara. Penyebab utama penuaan kulit akibat faktor ekstrinsik berupa pajanan kronik sinar ultraviolet dikenal sebagai photoaging. Tanda klinis photoaging dapat bervariasi, namun yang sering ditemukan berupa perubahan pigmentasi dan keriput. Saat ini telah tersedia lebih dari 100 instrumen penilaian penuaan kulit menggunakan fotografi, dermoskopi, dan alat diagnostik multifungsi namun masih belum ada yang dianggap sebagai baku emas. Tinjauan pustaka ini bertujuan untuk membahas berbagai instrumen penilaian photoaging yang sering digunakan dalam praktik klinis sehari-hari dan karakteristik dari masing-masing instrumen tersebut.

Nomophobia, yang disingkat dari “no mobile phone phobia”, merupakan rasa cemas ketika seseorang terpisah dari telepon genggamnya. Selama ini, salah satu hal yang dianggap sebagai faktor risiko nomophobia adalah kesepian, yaitu pengalaman emosional yang tidak menyenangkan ketika seseorang mengalami kekurangan kuantitas dan kualitas hubungan sosial. Penelitian ini bertujuan untuk mengetahui hubungan antara nomophobia dengan kesepian pada kelompok yang berusia dewasa muda (19-22 tahun) terutama dengan diberlakukannya sistem pembelajaran campuran (daring dan luring). Sebanyak 110 (39 laki-laki dan 71 perempuan) mahasiswa kedokteran Universitas Kristen Krida Wacana angkatan 2018 mengisi kuesioner daring menggunakan Nomophobia Questionnaire (NMP-Q) dan UCLA (University of California Los Angeles) Loneliness Scale version 3 yang sudah divalidasi ke dalam Bahasa Indonesia. Berbeda dengan penelitian-penelitian sebelumnya, hasil survey ini tidak menemukan korelasi  antara tingkat kesepian dengan tingkat nomophobia. Perlu dikaji lebih lanjut kemungkinan bahwa tatap muka pembelajaran secara terbatas mengubah pola penggunaan telepon genggam maupun interaksi sosial dibandingkan dengan kondisi sebelum masa pandemi maupun saat pembelajaran jarak jauh sepenuhnya.
