  • Two categories of cosmetic products, cosmetics and quasi-drugs, have been established by the Ministry of Health, Labor and Welfare (MHLW) in Japan. Japanese pharmaceutical law has defined that products categorized as cosmetics do not exhibit any effects on human skin. In fact, cosmetic products are not permitted to claim any efficacy. On the other hand, products in the quasi-drug category can claim several efficacies such as anti-inflammatory effects, whitening/lightning effects, hair growth effects and so on. Unfortunately, the Japanese MHLW has not yet approved the efficacy of anti-aging/anti-wrinkle effects as a claim point. However, the population is aging, and the demand for anti-aging/anti-wrinkle products is increasing year by year. Japanese cosmetic companies have proposed to the MHLW that anti-aging/anti-wrinkle agents be approved as a claim concept of a quasi-drug. However, unified evaluation methods for anti-aging/anti-wrinkle effects have not been established. Currently, each company evaluates the efficacy of products/materials using their own original methods. Thus, to request approval of the MHLW, the establishment of a unified evaluation method is needed. Consequently, the Japan Cosmetic Industry Association (JCIA) has established a task force to develop guidelines for evaluating anti-wrinkle effects in 1998. In conclusion, the JCIA would like to adopt visual and image analysis scales to evaluate the anti-wrinkle effects objectively. Generally, wrinkles are roughly classified into three groups as fine wrinkles, linear deep wrinkles and crow's feet. However, academic societies of dermatology or cosmetics have not yet established a definition of wrinkles in Japan. Thus, in advance of setting up an evaluation method, the definition of wrinkles f3r evaluation must be decided. Wrinkles are defined by the task force of the JCIA as follows; furrows that people can recognize visually and that appear on the forehead, the corners of the eyes and the backs of the neck with aging. In addition, furrows are emphasized by exposure to solar light and by dry conditions. Visual evaluation is the most sensitive method and can be applied to most types of wrinkles. However, visual evaluation is hard to express digitally as results. Besides, in the case of image analysis, comparisons of data obtained from distinct examinations can not be done, because data from image analysis are relative values. Thus, to enhance the reliability of the evaluations, the adoption of an objective scale was required. The principle of the evaluation method is to analyze images taken from silicone replicas of wrinkle areas using several parameters, such as the proportion of the wrinkle $area({\%})$, the mean depth of the wrinkles (mm), the mean depth of the deepest wrinkle (m) and the deepest point on the deepest wrinkle. Lights are shown on the skin replica from an orthogonal direction of the main orientation of the wrinkle, and the resulting shadow images are quantified by the image analysis method. To increase the precision of the data or to allow comparisons of independent examinations, a scale with furrows of several depths, 200, 400, 600, 800, and $1000{\mu}m$, is adapted in the evaluation system. I will explain the guidelines established by the JCIA in the presentation.

  • 최근 다양한 공공데이터가 개방되고 있으며, 적절한 데이터 마이닝과 시각화 알고리즘을 통해 일반 시민에게 서비스 되고 있다. 이를 통해 정부와 지방자치단체는 공공 정책의 투명성과 효율성을 널리 알릴 수 있을 뿐 아니라, 일반 사용자들이 개방된 공공데이터를 재가공하여 서비스함으로써 관련 산업의 성장을 이끌고 있다. 공공데이터의 최종 사용자는 일반 시민이기 때문에, 누구나 손쉽게 이해할 수 있도록 공공데이터를 적절히 시각화하는 것이 무엇보다 중요하다. 본 연구에서는 공공데이터 비주얼라이제이션의 중요성을 널리 알리기 위해, 일반 국민이 관심을 가질만한 공공데이터로 UN 회원국의 투표 데이터를 고려한다. 외교와 교육 목적으로 그 활용 가치가 높고 데이터를 쉽게 얻을 수 있는 장점이 있다. 또한 적절한 데이터 마이닝과 시각화 과정을 거친다면, 일반 사용자들이 유엔 회원국 간의 투표 성향에 대한 통찰력을 쉽게 얻을 수 있다. 유엔 투표 데이터를 시각화하기 위해서는, 회원국 간의 투표성향 유사도를 측정하고, 이를 바탕으로 소셜 그래프를 구현한다. 그리고 그래프 레이아웃 알고리즘을 적용하여 그래프를 화면에 렌더링 하게 된다. 기존 방법을 이용하여 소셜 그래프를 비주얼라이제이션 할 경우에 그래프의 복잡도가 증가하여 유엔 회원국 간의 투표성향을 파악하는데 큰 어려움이 있다. 이러한 문제를 개선하기 위해, 본 논문에서는 친구 매칭(Friend-Matching), 친구-라이벌 매칭(Friend-Rival Matching), 버블힙(Bubble Heap) 알고리즘들을 차례로 제안한 다. 제안된 알고리즘을 바탕으로, 기존 그래프 비주얼라이제이션을 개선하여 일반 사용자들이 손쉽게 유엔 회원국 간의 투표성향과 관련된 특정 패턴이나 통찰력을 얻는데 큰 도움을 줄 것이다. 또한 웹에서 동작하는 프로토타입을 구현하여, 누구나 방문하여 테스트를 할 수 있다. 웹 페이지 주소: http://datalab.kunsan.ac.kr/politiz/un/

  • The purpose of the study was to identify disease characteristics and behavior pattern of treatment for patients with Fibromyalgia. This study was carried out between May to Aug. in 1998 through direct interview in Rheumatism clinic at H. University Hospital and subject in this study were 125 outpatients diagnosed with Fibromyalgia. Collected data were analyzed by descriptive statistics and t-test, ANOVA using SPSS Window program. The results of this study are as follows. 1. General Characteristics : All of the persons with Fibromyalgia were female who were mostly in their forties(37.5%). A third of them(38.4%) were graduated from high school. The greatest part of them(54.4%) were christians but little part of them(16.8%) were employed 2. Disease Characteristics : They have struggled with Fibromyalgia for 10 years on an average. About half of them(56.9%) suffered from Fibromyalgia only but the others had another diseases which were in greatest part occupied by Osteoarthritis. The number of tender point which is a feature of Fibromyalgia differed according to measuring criteria. Yunus criteria. however, was proved to be the most proper measuring criteria than any other method as it showed high correlations between symptoms and physical activities. The most serious symptoms that complained the patients among subjective symptoms are pain, sleep disorder, and fatigue in sequence, and activities most hard to do among physical activities are washing by hand, scrubbing by hand, and shopping in sequence. 3. Behavior Pattern of Treatment : The largest part of them(42.4%) had received medical treatment after they were determined to have the disease and most of them were taking medicine as prescribed by physician(88.8%) or other medicines(16.8%), Of them, two thirds stated that the medicine they took were effective. Around a third of them took exercises mostly composed of swimming. The medical institution they visited in the past were orthopedic surgical department, Oriental hospital, physical therapy department in sequence and, in a slight percent(11.4%), psychiatric department. 4. Relations between Disease Characteristics and Behavior pattern of Treatment : It shows that number of tender point and level of symptom are significantly different according to duration of disease and medical intervention. As a results, it can be suggest that persons with Fibromyalgia need to take exercises and medicine continually regardless of medical treatment as it is a chronic disease whose symptoms are hardly mitigated.

  • Purpose - This study empirically investigates the effects of Official Development Assistance (ODA) on the economic activities of private actors in recipient countries. As a proxy for the economic activities of private actors, we utilize the job creation activities of foreign subsidiaries in recipient countries. The foreign subsidiaries provide a foundation for economic development by creating paying jobs. That is, if ODA has been successfully transferred to foreign subsidiaries, then these foreign subsidiaries should help economic growth and help create a boom in the local market by providing jobs. These jobs eventually lead to the achievement of the primary aims of foreign aid, including poverty reduction. Thus, this study empirically examines the relationship between ODA and the number of jobs created by foreign subsidiaries in recipient countries. Design/methodology - This is the first study to examine the effects of the ODA on the job creation of foreign subsidiaries because it has been hard to obtain internal information related to the employment status of foreign subsidiaries. Fortunately, we have a unique panel dataset provided by the Export-Import Bank of Korea (KEXIM) for 2006 to 2013. In terms of the empirical specification, we use the generalized least squares (GLS) method. The panel GLS estimator allows us to have an efficient estimation that overcomes the limitations of the panel data. It employs assumptions about the heteroscedasticity between the panels and makes an autocorrelation of the error term within each panel. Findings - We find that ODA influences job creation in foreign subsidiaries. In particular, we found that ODA creates more jobs in sales than in managerial or production positions. This study also shows that the effect of the ODA on the foreign subsidiaries' job creation activities depend on the purpose of the ODA. By examining ODA effects on the foreign subsidiaries' economic activities (e.g., job creation), this study fills a gap in the current literature. Originality/value - Existing studies that focus on the ODA effect have either a macroeconomic point or a microeconomic point of view. However, both approaches do not explain how well foreign aid has influenced private economic actors of recipient countries. In essence, previous researchers found it difficult to obtain the necessary data for internal employment status from foreign subsidiaries. However, thanks to the Korea Export-Import Bank, this study shows that ODA indeed influences the job creation activities of foreign subsidiaries even after controlling for other factors such as FDI, GDP growth rate, employment rate, household expenditure, mother firms' share, etc. By doing so, we can examine how ODA influences the job creation of foreign subsidiaries, which might help economic development and reduce the amount of poverty in recipient countries.

  • 기존의 운영체제에서 하드디스크의 성능을 향상시키기 위해서 사용해왔던 기술들이 SSD(Solid State Drive)에는 부정적 효과를 나타내는 경우가 많다. HDD의 기계적인 요소 때문에 접근 시간과 블록 주소의 순서가 성능에 매우 중요한 요인으로 작용하였지만, SSD는 불록 주소의 순서에 영향을 받지 않는 우수한 랜덤 읽기 성능을 제공한다. 실제 개인용 PC에서 SSD를 사용할 때에 선반입을 끄도록 권고되고 있다. 하지만 이 논문은 SSD의 내부 구조와 낸드 플래시 메모리의 특징을 고려한 선반입 및 메모리관리 정책를 결합한 방법을 제시한다. SSD에는 다수개의 낸드 플래시 메모리로 구성되어 있어 칩을 동시에 구동시키는 것이 중요하며, 낸드 플래시 메모리의 기본 입출력 단위가 계속 증가하는 방향으로 발전하고 있어서 SSD 내부의 동작 단위가 운영체제의 블록 크기보다 훨씬 커지게 되었다. 이 논문은 이러한 SSD의 특징과 경향을 수용하여, 제안하는 선반입 기법은 SSD의 동작 단위로 수행되며, 제안하는 메모리 관리 기법은 그 선반입 기법의 단점을 보완하여, 캐시 히트율과 선반입 히트율의 합이 최대가 되도록, 선반입되었지만 사용되지 않는 데이터를 적응적으로 퇴출한다. 본 기술은 리눅스 커널 모듈로 개발하였으며 실제 SSD를 사용하여 성능 평가를 실시하였다. 주어진 실험에서 제안하는 선반입 기법이 약 26%까지 성능을 향상시켰다.

  • Purpose: The aim of this study was to develop an automated software to extract tooth and pulpal area from sectional cone-beam computed tomography (CBCT) images, which can guarantee more reproducible, objective and time-saving way to measure pulp/tooth volume ratio. Methods: The software program was developed using MATLAB (MathWorks). To determine the optimal threshold for the region of interest (ROI) extraction, user interface to adjust the threshold for extraction algorithm was added. Default threshold was determined after several trials to make the outline of extracted ROI fitting to the tooth and pulpal outlines. To test the effect of starting point location selected initially in the pulpal area on the final result, pulp/tooth volume ratio was calculated 5 times with different 5 starting points. Results: Navigation interface is composed of image loading, zoom-in, zoom-out, and move tool. ROI extraction process can be shown by check in the option box. Default threshold is adjusted for the extracted tooth area to cover whole tooth including dentin, cementum, and enamel. Of course, the result can be corrected, if necessary, by the examiner as well as by changing the threshold of density of hard tissue. Extracted tooth and pulp area are reconstructed three-dimensional (3D) and pulp/tooth volume ratio is calculated by voxel counting on reconstructed model. The difference between the pulp/tooth volume ratio results from the 5 different extraction starting points was not significant. Conclusions: In further studies based on a large-scale sample, the most proper threshold to present the most significant relationship between age and pulp/tooth volume ratio and the tooth correlated with age the most will be explored. If the software can be improved to use whole CBCT data set rather than just sectional images and to detect pulp canal in the original 3D images generated by CBCT software itself, it will be more promising in practical uses.

  • Adverse side-effects and lack of scientific validation of some chemotherapeutic agents prevent the use of many traditional medicines claimed to have anti-cancer effects. Ethanolic extract of Conium maculatum has long been used in traditional and alternative systems of medicine including homeopathy for the treatment of glandular enlargements, cancerous tumours or hard lumps of testicles, prostate, ovaries, breasts and/ or uterus, particularly in the breast. However, if and how it acts still remains scientifically unknown. This study aims to test if Conium extract (CE), used as mother tincture of Conium in homeopathy, has demonstrable anti-cancer potentials without having much cytotoxicity in normal cells. Cytotoxicity of the drug was tested by conducting MTT assay on both normal (peripheral blood mononuclear cells) and HeLa cells. We also evaluated DNA fragmentation and DNA damage by DAPI and diphenylamine assay. The LDH activity assay was done to evaluate the percentages of apoptosis and necrosis. ROS accumulation also was evaluated to pin-point the actual events of apoptosis. Administration of drug clearly demonstrated its anti-cancer potentials as evidenced by the DNA damage analysis. The ROS activity also increased in case of the CE treated cells. LDH data revealed that the mode of cell death was mainly apoptotic and not necrotic. CE appears to induce apoptosis of cancer cells through ROS mediated pathway, and has negligible cytotoxicity against normal cells.

  • This research was to identify the relationships between sex role attitude and the preference of fashion advertising formatted by sex role expression, and to examine the relationships among sex role attitude and sociographic variables. This research has been done for 618 university students and working group who are living in Cheongju and Seoul. For data analysis, descriptive analysis, ANOVA, and t-test were used. The results are the following: 1. In the view of the preference of fashion advertising, the stereotypical fashion advertising has more point than the androgynous fashion advertising. 2. The advertising formation preference showed a little difference significantly by sex role attitude. The group with conservative sex role preferred the stereotypical fashion advertising. The group with open-minded sex role preferred the androgynous fashion advertising. 3. Women preferred the androgynous advertising. As the aged, they preferred the stereotypical fashion advertising and have the conservative sex role. University students have more intention to buy with an androgynous fashion commercial than working group have and they have the open-minded about sex. The group subscribed the fashion magazine has more preference for androgynous fashion advertising, as they have more open-minded sex role than other group not subscribed the fashion magazine. This results imply that the androgynous formatted advertizing is still hard to get the influence of a general market promotion because most consumers have a low androgynous fashion advertizing preference. The preference of the fashion advertizing which expressed a sex role showed significant differences as social demographics, and a sex-role attitude. Therefore, the market segment and advertising strategies which are based on sex role and consumer characteristics would be very effective.
