컴퓨터 바둑에 있어서 형세 평가는 일반화되어 있지 않다. 정확한 평가를 위해서 국면의 변화에 따른 361 자리의 소유 여부를 분명히 할 필요가 있다. 본 논문에서는 바둑의 규칙과 특성을 분석하는 방법으로 그래프 표현을 적용하였으며, 돌의 세기, 영향력, 안정도, 자리값, PM 등의 요소를 정의하여 임의의 국면에 대한 형세를 평가하는 시스템(SES)을 제안하였다. 이는 혹, 백간의 영역 차이를 명백하게 표현하므로 바둑의 전반적인 형세를 평가하는데 매우 효과적이다. 결론적으로 SES는 초반의 형세 평가에 매우 우수하며, 프로기사에 대한 254개의 실전 기보에 대해서 70.9%의 적중률을 보였다. 정석 사례를 구축하여 사용하는 상용 프로그램, Nemesis와 비교 실험한 결과에 의하면, 프로기사에 대한 형세 평가 적중률에 있어서 SES는 Nemesis보다 전체적으로 10% 앞서는 것으로 나타났다.

Objectives: About for twenty years, immigrant women in South Korea have steadily increased due to economic growth and industrialization. According to previous studies in terms of immigrants, subjective socio-economic status(SES) as well as objective SES such as income, occupation and level of education predict health outcomes. The purpose of this study was to examine association between subjective social status and perceived health among immigrant women. Methods: We analyzed 12,531 participants from the 2012 National Survey of Multicultural Families. Study variables included subjective SES in Korea, subjective SES in community and perceived health. Control variables were age, household income, employment, education, marital status, ethnicity, language proficiency. For this study, descriptive analysis, Chi-square test, and multivariate logistic regression analysis were performed. Results: Among immigrant women, after adjusting for control variables, level of education in community was not associated with perceived health. Otherwise, subjective social status in Korea(low subjective social status reference group vs high subjective status : OR 2.056) was associated with perceived health. Conclusions: Immigrant women in Korea would be culturally affected by inherent characteristic rather than social economic status. Through this study, in order to improve health inequality among immigrant women, we should consider developing social supports and networks.

The current experiment was conducted to compare nutrient utilization in the aged laying hens with different eggshell strengths or different intensities of brown eggshell color. Two metabolic trials with 96-week-old Hy-Line Brown laying hens were conducted. Twelve hens with a strong eggshell strength (SES) and 12 hens with a weak eggshell strength (WES) were selected and used in the first experiment, whereas 12 hens with dark brown eggshells (DBE) and 12 hens with light brown eggshells (LBE) were selected and used in the second experiment. All hens were fed a common commercial layer diet. Diets included chromic oxide as an indigestible marker to determine the apparent total tract retention (ATTR) of the gross energy (GE), dry matter, acid-hydrolyzed ether extract, nitrogen, neutral detergent fiber, acid detergent fiber, ash, and minerals. The results indicate that the ATTR of Ca in the aged laying hens with SES (59.7%) was greater (p < 0.05) than in the aged laying hens with WES (48.6%). However, the ATTR of the GE and other nutrients was not different between the hens with SES or WES. There were no differences in the ATTR of GE and nutrients between the hens with DBE or LBE. In conclusion, aged laying hens with SES have a greater ability to utilize dietary Ca than those with WES, indicating that the extent of dietary Ca utilization determines the eggshell strength of aged laying hens. However, nutrient utilization in diets may have little impact on eggshell brown coloration in aged laying hens.

Objectives : This study aimed to investigate the relationship between the level of ego-resilience and depression, anxiety, conduct problems and self-esteem in a large sample of Korean adolescents. Methods : A total 4508(2036 males and 2472 females) middle and high school students in Gwang-ju metropolitan city were included in this study. Subjects were asked to complete a self-reported questionnaire, including Ego-Resilience(ER) scale, Beck Depression Inventory(BDI), Beck Anxiety Inventory(BAI), Self-Esteem Scale(SES), 15 items in Korean-Youth Self Report(K-YSR) to measure conduct problems and demographic variables. Subjects were classified into three high, intermediate and low ER group according to total ER scale scores. Results : Total ER scores was positively correlated with total SES scores and negatively correlated with total BDI, BAI, and conduct problem scores. Using analysis ANOVA(analysis and variance) and post hoc test, significant mean differences in BDI, BAI, SES and conduct problem scores were observed among the three groups. High ER group showed that SES scores were significantly higher and BDI, BAI and conduct problem scores were significantly lower than that observed in middle and lower ER group. Using multiple regression analysis, the results showed that depression, low self-esteem were significant factors affecting ego-resilience in adolescents. Conclusion : Our findings indicate that depression, anxiety, behavioral problem such as conduct problems and low self-esteem are associated with low ego-resilience.

본 연구의 목적은 소셜미디어 정서전염척도(Social Media Emotional Contagion Scale, SECS)를 개발하고 타당화를 하는 것이다. 전국의 20대 성인을 대상으로 결측을 제외한 총 326명을 대상으로 진행되었으며, SECS의 높은 신뢰도를 확보하였다. EFA와 CFA를 통해 SECS가 2요인 구조임을 확인하였고 한국판 정서전염 척도(K-ECS), 성인 공감척도(BES-A), Rosenberg 자아존중감척도(SES)와의 준거관련타당도를 확인하였다. SECS는 K-ECS와 BES-A의 정서적 전염과 관련된 하위요인과는 수렴하였지만, K-ECS와 BES-A 전체 척도와는 변별되었다. 이는 오프라인상에서 나타나는 정서전염과 소셜미디어상에서 나타나는 정서전염을 구별할 필요성을 시사한다. SES와는 변별되었으나 SES의 하위요인과는 일부 수렴하고 일부 변별되었다. 더 나아가, IRT를 시행하여 SECS가 높은 변별도와 적절한 심각도 문항으로 구성된 타당한 척도임을 확인하였다. 마지막으로, SECS 척도의 기준점을 제시하였고 본 연구의 의의와 제한점 및 추후 연구에 대해 논의하였다.

Objectives: Economic hardship has a serious impact on adolescents' mental health. The financial impact of the coronavirus disease 2019 (COVID-19) pandemic was more severe for low-income families, and this also impacted adolescents. This study aimed to examine the associations of economic deterioration (ED) caused by the COVID-19 pandemic and low socioeconomic status (SES) with adolescents' suicidal behaviors. Methods: This study analyzed data from the 2020 Korea Youth Risk Behavior Web-based Survey, which included 54 948 middle and high school students. Odds ratios (ORs) of suicidal ideation, suicidal planning, and suicide attempts related to ED and SES were calculated using multivariable logistic regression. We calculated relative excess risks due to interaction to assess additive interactions. Results: The ORs for suicidal ideation, suicidal planning, and suicide attempts related to combined severe ED and low SES were 3.64 (95% confidence interval [CI], 3.13 to 4.23), 3.88 (95% CI, 3.09 to 4.88), and 4.27 (95% CI, 3.21 to 5.69), respectively. Conclusions: ED and low SES were significantly associated with suicidal behaviors in adolescents. Although no significant additive interaction was found, the ORs related to suicidal ideation, suicidal planning, and suicide attempts were highest among adolescents from low-income families with severe ED. Special attention is needed for this group, considering the increased impact of economic inequality due to the COVID-19 pandemic.

Objectives: Socioeconomic inequality in metabolic syndrome (MetS) remains poorly understood in Iran. The present study examined the extent of the socioeconomic inequalities in MetS and quantified the contribution of its determinants to explain the observed inequality, with a focus on middle-aged adults in Iran. Methods: This cross-sectional study used data from the Ravansar Non-Communicable Disease cohort study. A sample of 9975 middleaged adults aged 35-65 years was analyzed. MetS was assessed based on the International Diabetes Federation definition. Principal component analysis was used to construct socioeconomic status (SES). The Wagstaff normalized concentration index (CI_n) was employed to measure the magnitude of socioeconomic inequalities in MetS. Decomposition analysis was performed to identify and calculate the contribution of the MetS inequality determinants. Results: The proportion of MetS in the sample was 41.1%. The CI_n of having MetS was 0.043 (95% confidence interval, 0.020 to 0.066), indicating that MetS was more concentrated among individuals with high SES. The main contributors to the observed inequality in MetS were SES (72.0%), residence (rural or urban, 46.9%), and physical activity (31.5%). Conclusions: Our findings indicated a pro-poor inequality in MetS among Iranian middle-aged adults. These results highlight the importance of persuading middle-aged adults to be physically active, particularly those in an urban setting. In addition to targeting physically inactive individuals and those with low levels of education, policy interventions aimed at mitigating socioeconomic inequality in MetS should increase the focus on high-SES individuals and the urban population.

CCSDS Standard is widely used in the international space telecommunication area. But standard recommendation of CCSDS is not restrictive, so, we can select an appropriate encryption protocol among the layer. For synchronization, encryption sync is attached in the beginning of the encrypted data. In the exceptional environmental condition, although the receiver can not decrypt the normal data, the sender have no conception of that situation. In this paper, we propose a two-stage SES alarmed link encryption synchronization method having optimized threshold value necessary to decide whether the receiver has a correct decryption or not. first, through the experiment of mutual relations between error rate and encryption synchronization detection error, we can predict worst communication environment for the selected encryption synchronization pattern. second, through the experiment for finding what number of consecutive frame synchronization error is an appropriate reference value and analysis of that experiment, we suggest an optimized threshold value for resynchronization request. lastly, through the output images we can predict the probability error that should be guaranteed by channel coder.
