This study investigates the temporal and spatial variations of marine meterological elements (air temperature (Temp), Sea Surface Temperature (SST), and Significant Wave Height (SWH)) in seven coastal waters of South Korea, using hourly data observed at marine meteorological buoys (10 sites), Automatic Weather System on lighthouse (lighthouse AWS) (9 sites), and AWS (20 sites) during 2013-2017. We also compared the characteristics of Temp, SST, and air-sea temperature difference (Temp-SST) between sea fog and non-sea-fog events. In general, annual mean values of Temp and SST in most of the coastal waters were highest (especially in the southern part of Jeju Island) in 2016, due to heat waves, and lowest (especially in the middle of the West Sea) in 2013 or 2014. The SWH did not vary significantly by year. Wind patterns varied according to coastal waters, but their yearly variations for each coastal water were similar. The maximum monthly/seasonal mean values of Temp and SST occurred in summer (especially in August), and the minimum values in winter (January for Temp and February for SST). Monthly/seasonal mean SWH was highest in winter (especially in December) and lowest in summer (June), while the monthly/seasonal variations in wind speed over most of the coastal waters (except for the southern part of Jeju Island) were similar to those of SWH. In addition, sea fog during spring and summer was likely to be in the form of advection fog, possibly because of the high Temp and low SST (especially clear SST cooling in the eastern part of South Sea in summer), while autumn sea fog varied between different coastal waters (either advection fog or steam fog). The SST (and Temp-SST) during sea fog events in all coastal waters was lower (and more variable) than during non-sea-fog events, and was up to -5.7℃ for SST (up to 5.8℃ for Temp-SST).

Objective : The purpose of this study was to investigate the longitudinal trajectories of life satisfaction, loneliness, and depression and to identify the factors that influence these trajectories in North Korean Defectors (NKD). Methods : NKD (n=300) who registered in the multi-regional adaptation center (Hana Center), within three years of settling in South Korea, were recruited into this study. Life satisfaction, loneliness, and depression were assessed with self-report questionnaires over a period of 4 years (7 waves of data). Latent growth modeling was conducted to assess the changes in life satisfaction, loneliness, and depression. Results : Findings from both unconditional and conditional models (with gender, South Korea settlement age, household income, marital status, and PTSD at wave 1) indicated a linear increase in loneliness and depression, and a linear decrease in life satisfaction over the 4-year period. In the conditional model, gender predicted the intercept of life satisfaction and depression. In addition, PTSD predicted the intercept of life satisfaction, loneliness, and depression and slope of depression. Conclusion : Our finding suggests that the mental health of NKD tends to deteriorate over time after settling in South Korea. Therefore, continuous support is necessary for their successful adaptation to the South Korean Society.

유전체 코호트 연구의 주요 통계학적 과제

박소희,Park, So-Hee 대한예방의학회 2007 예방의학회지 Vol.40 No.2

When conducting large-scale cohort studies, numerous statistical issues arise from the range of study design, data collection, data analysis and interpretation. In genomic cohort studies, these statistical problems become more complicated, which need to be carefully dealt with. Rapid technical advances in genomic studies produce enormous amount of data to be analyzed and traditional statistical methods are no longer sufficient to handle these data. In this paper, we reviewed several important statistical issues that occur frequently in large-scale genomic cohort studies, including measurement error and its relevant correction methods, cost-efficient design strategy for main cohort and validation studies, inflated Type I error, gene-gene and gene-environment interaction and time-varying hazard ratios. It is very important to employ appropriate statistical methods in order to make the best use of valuable cohort data and produce valid and reliable study results.

Purpose: The purpose of this study was to develop a valid tool for measuring the work environment of Korean nurses and test the validity and reliability of the instrument. Methods: This is a methodological study for developing and testing a measurement tool. The conceptual framework for the tool was formed through a literature review and in-depth interviews with clinical nurses. 260 meaningful statements were derived through this process, and 59 of the primary items were generated out of these statements. On the basis of the content validity test, 41 items were selected for the preliminary tool. A total of 350 nurses from 7 hospitals responded to the preliminary questionnaire in October 2011. Results: After the item analysis and the principal component analysis using varimax rotation methods, 11 items were deleted. Considering the conceptual framework and the scree plot, we extracted 4 factors from the final 30 items. These factors were organizational support, head nurse's leadership, support system, and relationship with coworkers, and their total variance was 54.4%. The value of Cronbach's ${\alpha}$ of the final tool was 0.92. Conclusion: The above findings revealed that the Korean Nursing Work Environment Scale (K-NWES) is an appropriate, valid, and reliable tool for evaluating the work environment of Korean nurses. Further research to perform a criterion validity test of the K-NWES is needed.

레이저로 가공된 평면산란패턴을 가지는 도광판은 도광판 상부로 방출되는 광이 광원과 가까운 부분에 편중되는 문제로 인해서 전체적인 휘도 분포가 균일하지 않은 문제점을 가지고 있었다. 이를 해결하기 위해 도광판 후면에 레이저를 이용하여 도광판 내부에서 특징적인 기울기를 가지는 산란패턴을 만듬으로써 도광판 상부로 방출되는 광의 균일도를 향상시키고자 하였다. 본 논문에서는 도광판 후면의 산란패턴을 간격과 가공 깊이를 다르게 조절하여 설계하고 이에 따른 도광판의 성능의 차이점을 가공전에 분석하고자 전산모사를 수행하였다. 본 논문에서 제안한 산란패턴을 가지는 도광판은 기존의 도광판의 휘도와 균일도에 비해 높은 향상을 가질 것으로 예상되는 바이다. Laser-induced scatterer patterns in a light guide panel(LGP) have provided partially concentrated light distribution, especially near the light entrance of the LGP. Additional treatments for enhancing performance of the LGP, such as gradually increased processing depth, were also developed, but minor improvement was observed in the fabricated LGP. To solve this problem, we designed a revised scatterer pattern to be inscribed into the LGP using different laser processing depths and different separation distances between patterns. Performance feasibility of the proposed pattern was analyzed with simulation before laser inscription in the LGP. The LGP inscribed with the proposed scatterer patterns contributes improvements in luminance and uniformity of the LGP.

병렬프로그램의 경합조건을 수행 중에 효율적으로 탐지하기 위한 레이블링 기법

박소희,우종정,배종민,전용기,Park, So-Hee,Woo, Jong-Jung,Bae, Jong-Min,Jun, Yong-Kee 한국정보처리학회 2002 정보처리학회논문지 A Vol.9 No.4

병렬프로그램에서 경합 조건은 비결정적인 수행 결과를 초래하므로 디버깅을 위해 반드시 탐지되어야 한다. 이러한 경합을 수행 중에 탐지하는 기존의 기법들은 병행성 정보 생성 시에 공유 자료구조를 사용하여 심각한 병목현상을 발생시키거나, 병행성 정보 비교 시에 내포병렬성의 정도에 의존하는 비효율적인 시간 복잡도를 가진다. 본 논문에서는 개별 자료구조를 사용함으로써 병목현상을 제거하여 병행성 정보를 확장적으로 생성하며, 생성된 병행성 정보의 비교 시간을 상수적인 복잡도로 개선한 새로운 레이블링 기법을 제안한다. 그러므로 제안된 레이블링 기법의 확장성 및 효율성은 공유메모리와 메시지전달 프로그램뿐만 아니라 이를 혼합하여 사용하는 병렬프로그램에서도 효율적인 수행중 경합탐지를 가능하게 한다. Race conditions, races in short, need to be detected for debugging parallel programs, because the races result in unintended non-deterministic executions. To detect the races in an execution of program, previous techniques use a centralized data structure which may incur serious bottleneck in generating concurrency information, or show inefficient time complexity which depends on the degree of nested parallelism in comparing any two of them. We propose a new labeling scheme in this paper, which is scalable in generating the concurrency information without bottleneck by using private data structure, and improves time complexity into constant in checking concurrency. The scalability and time efficiency therfore makes on-the-fly race detection efficient not only for programs with either shared-memory or message-passing, but also for programs with mixed model of the two.

This study focused on service blueprints, which are being utilized in the final stage of the domestic 4D design process. The purpose of the study is to increase usability so that it can be applied and modified according to the topic. The method of the study investigated the data through prior papers and books, followed by case development analysis and interviews by three teams. The construction of the study is first investigated on design scenarios, scenario description swim lanes, and service blueprints for theoretical backgrounds, and studied on concepts, structures, and components. Second, we examine the current status and limitations of service blueprints for rearrangement and application of components and summarize the modifiable and complementary components presented by leading researchers. This allows us to rearrange the components of scenario description swim lanes and service blueprints so that they can be added, modified and utilized. Third, the case development analysis of the three teams showed that the use of the deliverables could be more specific and that the process of ‘user experience’ could be highlighted depending on the topic. It also added business lanes to assess the feasibility of the developed output. After the case development, the pros and cons and improvements were summarized through interviews. This study conducted development examples of three teams, and later on, the same topic will be selected, and research on combination with other leading methodologies will also be needed.
