This is about an environmental study of groundwater interference by hydrodynamic dispersion between the well A and well C in Dongsam-dong, the Yeongdo Island, Pusan, Korea. The groundwater in the study wells come from the fracture zones deeply seated in welded lapilli rhyodacitic tuff of the Late Cretaceous Yucheon Group. The boring depth at the well A is 190 meters, and the optimal pumping rate of the well A is about 100 cubic meters per day therein. The fractured aquifers in impermeable welded tuff show the conjugate fracturing type and are of anisotropic. The aquifers along two fracture zones in the well A are 80 and 100 meters in depth, respectively. It is not suggested that those fractured aquifers are simply connected between the well A and C. The sea level fluctuation by ebb and high tides in a day is not effective to the groundwater table in the well A. The pumping for 15 days at the well A doesn't give rise to any changes of the groundwater levels in the neighbor well C. The radius of influence of the well A is measured as less than 200 meters. The measuring electric conductivity for the test of salt tracer doesn't testify any relationship between the well A and the well C. There is the main difference between the well A and the well C on the basis of the water analysis of those wells. the well A is located in the high content zone of salt much over the standard value for drinking, whereas the other wells B. C. D are in the low content area of salt below the standard value. It is elucidated for the high content zone of salt in Yeongdo around the well A to have been uplifted over 20 meters.

This study was a cross-sectional descriptive investigation study that analyzed the effects of spiritual well-being on stress coping in twenties. Data collection period was from May 1, 2019 to May 20, and 207 people voluntarily participated in the study. The sub-factors of spiritual well-being consisted of religious well-being and existential well-being. The types of stress coping consist of active coping, passive coping, aggressive coping, evasive coping, and social supportive coping. Data was analyzed using frequency analysis, t-test, Pearson correlation and multiple regression analysis using SPSS 18.0. As a result of the analysis, 90 (43.5%) were male and 117 (56.5%) were female. The 71.0% of the participants had no religion, the Buddhists were 14.5%, other religions were 5.8%, Protestants were 4.3%, Catholics were 2.9%, and Won Buddhists were 1.4%. Active coping in stress coping was correlated with religious well-being (r=-.357, p<0.01) and existential well-being (r=.301, p<0.01) under statistical significance. Religious well-being was significantly higher in males (Mean=2.87, SD=.753) than females (Mean=2.49, SD=.772, p<0.01). Existential well-being was also higher in males (Mean=4.25, SD=.841) than in females (Mean=3.95, SD=.694, p<0.01). The religious well-being was significantly higher than active coping (t=6.183, p<0.01), passive coping (t=-3.595, p<0.01), aggressive coping (t=1.991, p<0.05). Existential well-being was significantly higher than active coping (t=5.339, p<0.01), aggressive coping (t=1.659, p<0.05), evasive coping (t=-3.709, p<0.05) at the statistical significance level. Based on the results, it can be suggested that it was necessary to systematically plan spiritual well-being program as a way to cope with stress by knowing that spiritual well-being positively affects active, aggressive stress coping.

A graph G is called a well covered graph if every maximal independent set in G is maximum, and co-well covered graph if its complement is a well covered graph. We study some properties of a co-well covered graph and we characterize when the join, the corona product, and cartesian product are co-well covered graphs. Also we characterize when powers of trees and cycles are co-well covered graphs. The line graph of a graph which is co-well covered is also studied.

The purpose of this study was to examine the relationship between the attitude towards well-being and life satisfaction, to investigate the effect of healthy lifestyle and attitude towards well-being on life satisfaction, and to explore the differences in well-being lifestyle factors, well-being attitude, and life satisfaction against demographic variables. This study gave a questionnaire survey to adults between the ages of 10 and 60 who lived in the Seoul, Daegu and Kyungbuk regions of South Korea. Data collected from the 285 respondents was analyzed using descriptive statistics, correlation, t-tests, ANOVA, factor analyses, and regression analysis. The lifestyle for well-being was categorized into four areas, social welfare oriented activity, use of environmentally friendly products, self-esteem enhancement, and sports activity. Three of these factors were significantly correlated with the attitude towards wellbeing. The results of the regression analysis suggested that healthy lifestyle and attitude towards well-being affected people's life satisfaction.

This study describes how a properly calibrated simulation method could be used to investigate the latchup immunity characteristics among the various high energy ion implanted CMOS twin well (retro-grade/BILLI/BL) structures. To obtain the accurate quantitative simulation analysis of retrograde well, a global tuning procedure and a set of grid specifications for simulation accuracy and computational efficiency are carried out. The latchup characteristics of BILLI and BL structures are well predicted by applying a calibrated simulation method for retrograde well. By exploring the potential contour, current flow lines, and electron/hole current densities at the holding condition, we have observed that the holding voltage of BL structure is more sensitive to the well design rule (p+to well edge space /n +to well edge space) than to the retrograde well itself.

Objective : The aims of this study are to investigate the correlation between spiritual well-being and the pattern of stress coping strategies, as well as understand how they impact depression and psychological well-being. Methods : We analyzed 320 undergraduate students in a capital area (135 males, 170 females; 15 students who answered irrelevantly were excluded). Spiritual well-being (religious and existential), stress coping strategies (active and passive), psychological well-being and, depression were rated using the Spiritual Well-Being scale, Ways of Coping checklist, Psychological Well-Being measurement, and Depression Scale (CES-D), respectively. For the analysis, we utilized Pearson correlation analysis and simple regression analysis. Results : The analysis revealed a positive correlation between Spiritual well-being and active coping strategies, a negative correlation between existential well-being and depression, and a positive correlation between religious well-being and psychological well-being. By regression analysis, it showed spiritual-well being affected depression negatively. Existential well-being, but not religious well-being, affected depression negatively. Furthermore, the impact of existential well-being on depression remained a strong predictor in males better than females. Existential well-being affected psychological well-being positively through active coping strategies. Conclusion : In this study, we verified a correlation between existential well-Being and active coping strategies which affected depression and psychological well-being in undergraduate students.

A new Triple well structure is proposed for improved latch-up immunity at deep submicron CMOS device. Optimum latch-up immunity process condition is established and analyzed with varying ion implantation energy and amount of dose and also compared conventional twin well structure. Doping profile and structure are investigated using ATHENA which is process simulator, and then latch-up current is calculated using ATLAS which is device simulator. Two types of different process are affected by latch-up characteristics and shape of doping profiles. Finally, we obtained the best latch-up immunity with 2.5[mA/${\mu}{m}$] trigger current using 2.5 MeV implantation energy and 1$\times$10$^{14}$ [cm$^{-2}$ ] dose at p-well

Purpose: This study is conducted to contribute to the improvement of Green Standard for Energy and Environmental Design(G-SEED) from the existing energy physical efficiency-centric system to the well-being-centric green building certification system. Method: In order to modify existing G-SEED Certification, three phases of research have been conducted; 1) identification of needs of well-being-centric environment-friendly construction certification system, 2) comparison of domestic certification system with WELL Building standard(WELL) which focuses on human health and promotion of wellness and 3) AHP analysis to sort out the supplement items from WELL. Result: We proposed four alternatives which should be preferentially introduced to the existing domestic certification system; addition of independent 'well-being' section(field) in G-SEED, insertion of 'well-being' indicators in each relevant section of G-SEED, addition of 'well-being' indicators in 'Innovative Design(ID)' of G-SEED and independent score systems for 25 items in a high priority.
