This study was conducted to investigate ego resilience, cognitive emotion regulation strategies, academic stress on mental health of nursing students and provide data to increase mental health for nursing students based on the results. This research involved 299 nursing students in B city. The analyzed by the t-test, ANOVA, Pearson's correlation coefficient, multiple regression using SPSS/WIN 22.0. In results of the study, the average of mental health was 3.77±.98. Mental health were positively correlated with ego resilience (r=.450, p<.001), cognitive emotion regulation strategies (r=.408, p<.001), and was negatively correlated with academic stress (r=-.469, p<.001). Regression analysis showed 38.4% of variance in nursing student's the mental health can by experience of dating with age (β=-.171, p=.001), adjustment to college life (β=.223, p<.001), ego resilience (β=.203, p<.001), cognitive emotion regulation strategies (β=.179, p=.001), academic stress (β=-.193, p=.001). The fallow-up survey about various factors influencing nursing student's the mental health increasing program developing are required.
This study defines the substance and multi-dimension of emotional reactions which Koreans have toward foreigners to find the starting point of change in values which is an inevitable task in this multi-cultural society. The results indicate that the Bogardus scale which has been used to measure the social distance toward the minority race is found to have limitations in explaining the closed attitude of Koreans toward 'nation' and 'kinship through marriage'. To supplement such limitations, exploration on attitudes toward foreigners from different native places is performed based on the 'evaluation', 'power' and 'activity' dimensions of the Affective Control Theory. As a result, Americans are highly evaluated in all three dimensions while Japanese are evaluated low in the 'evaluation' dimension and high in the 'power' and 'activity' dimensions. North Korean defectors and ethnic Koreans from China (the Chosun race) are high in evaluation but low in other dimensions. West Asians are evaluated low in all three dimensions. By comprehending the influencing factors and the relative influence of social distance, it proves that the 'evaluation' dimension is the common denominator in all groups while 'power' dimension toward Japanese and 'activity' dimensions toward Chinese and West Asians influence social distance. All foreigners excluding Americans receive closer social distance when having higher education level. Moreover, American women and older North Korean defectors receive closer social distance.

Oral implants must fulfill certain criteria arising from special demands of function, which include biocompatibility, adequate mechanical strength, optimum soft and hard tissue integration, and transmission of functional forces to bone within physiological limits. And one of the critical elements influencing the long-term uncompromise functioning of oral implants is load distribution at the implant- bone interface, Factors that affect the load transfer at the bone-implant interface include the type of loading, material properties of the implant and prosthesis, implant geometry, surface structure, quality and quantity of the surrounding bone, and nature of the bone-implant interface. To understand the biomechanical behavior of dental implants, validation of stress and strain measurements is required. The finite element analysis (FEA) has been applied to the dental implant field to predict stress distribution patterns in the implant-bone interface by comparison of various implant designs. This method offers the advantage of solving complex structural problems by dividing them into smaller and simpler interrelated sections by using mathematical techniques. The purpose of this study was to evaluate the stresses induced around the implants in bone using FEA, A 3D FEA computer software (SOLIDWORKS 2004, DASSO SYSTEM, France) was used for the analysis of clinical simulations. Two types (external and internal) of implants of 4.1 mm diameter, 12.0 mm length were buried in 4 types of bone modeled. Vertical and oblique forces of lOON were applied on the center of the abutment, and the values of von Mises equivalent stress at the implant-bone interface were computed. The results showed that von Mises stresses at the marginal. bone were higher under oblique load than under vertical load, and the stresses were higher at the lingual marginal bone than at the buccal marginal bone under oblique load. Under vertical and oblique load, the stress in type I, II, III bone was found to be the highest at the marginal bone and the lowest at the bone around apical portions of implant. Higher stresses occurred at the top of the crestal region and lower stresses occurred near the tip of the implant with greater thickness of the cortical shell while high stresses surrounded the fixture apex for type N. The stresses in the crestal region were higher in Model 2 than in Model 1, the stresses near the tip of the implant were higher in Model 1 than Model 2, and Model 2 showed more effective stress distribution than Model.
The purpose of the present study was to examine the relationship between the form of the clinical crowns in the maxillary anterior segment and the clinical feature of gingiva such as morphological characteristics and the gingival thickness. Fifty periodontally healthy subjects were clinically examined regarding the probing depth, the thickness of the free gingiva, and the width of the keratinized gingiva. From study models of the maxillary anterior region, the width at cervical third(CW) and the length(CL) of the clinical crown, the papillary height, and the gingival angle of the 6 anterior teeth were measured. Each tooth was classified into 4 groups (longnarrow, NL; narrow, N; wide, W; short-wide, WS) according to CW/CL ratio and all the data were compared between groups NL and WS using independent t-test. Stepwise multiple regression analysis was performed for each tooth region with the gingival thickness at the level of sulcus bottom, the width of keratinized gingiva, and gingival angle as the dependent variables. As the results, the NL group of the upper anterior teeth displayed, higher papilla height, and narrower keratinized gingiva, more acute gingival angle resulting in pronounced "scalloped" contour of the gingival margin, compared to the WS group. There was no significant difference between groups NL and WS with respect to probing depth and the gingival thickness. The regression analyses demonstrated that the gingival thickness in central incisors was significantly associated to the mesio-distal width and bucco-lingual width of the crown, and labial probing depth. The width of keratinized gingiva was significantly associated with labial probing depth in central incisors and with proximal probing depth and gingival angle in lateral incisors, and with labial and proximal probing depth, and gingival angle in canines. The gingival angle was significantly associated with papillary height and CW/CL ratio and additionally with proximal probing depth in central incisors, with the width of keratinized gingiva in lateral incisors, and with labial probing depth and the width of keratinized gingiva in canines. These results indicate that the form of clinical crown in upper anterior region could influence the clinical feature of gingiva and the influencing factors might be different according to the tooth region.
This study was conducted to examine the overall perception of importance and possibility of Korean food and globalization of Korean food.

(3) Students were very interested in globalization of Korean Food. (4) Perception of Korean food and its globalization were significantly different according to the levels of education. (5) As a result of analyzing the effect on globalization, quality and healthfulness of Korean food had a positive effect on globalization of Korean food.
Extended H ckel Theory and CNDO/2 MO calculation methods have been applied to $C_6H_5YCH_2Cl$(Y = None, -$CH_2$-, -O-, -S-, -CO-, -$SO_2$-). It has been shown that charge distributions in molecules are mainly controlled by the migration of valence inactive electron, giving the order of ${\sigma}$-acceptor and ${\pi}$-donor effects -O- > -S- > -$CH_2$- > -$SO_2$-. The -CO- group exceptionally acts as ${\sigma}$-donor and ${\pi}$-acceptor. It was also predicted that, $S_N2$ reactivities of C$C_6H_5YCH_2Cl$ would be in the order of -O-${\thickapprox}$-CO- >>-S-${\thickapprox}$None > -$CH_2$-, neglecting solvent effect. From the results of our studies, we conclude that the structural factors influencing 의 $S_N$ reactivities will be: (1) positive charge developments on reaction center carbon atom (2) energy level of ${\sigma}$-antibonding unoccupied MO with respect to C-Cl bond. (3) ${\sigma}$-antibonding strength of C-Cl bond at that level.

In this paper, we purpose to describe the relationship and influencing factors among self-esteem, loneliness on subjective well-being of middle-aged women. The subjects were 157 middle-aged women through convenience sampling residing in S city, C and three G provinces. The data were collected from June 15th to July 31st, 2019. The data were analyzed through t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 22.0. The result showed self-esteem, loneliness on subjective well-being averaged 31.39(out of 40), 35.37(out of 80), 5.03(out of 7). In term of correlations, subjective well-being of middle-aged women was significantly positively correlated with self-esteem (r=.581, p<.001), and significantly negatively related with loneliness (r =-.621, p<.001)). Variables affecting subjective well-being were self-esteem (β=.324 p<.001), loneliness(β=-.424, p<.001). These variables represented 44.5% of the subject's subjective well-being. These results suggest that development of a intervention program is needed to lowers loneliness and increases self-esteem in order to increase the subjective well-being of middle-aged women.
The monthly water quality data measured at 19 stations located in the Sapkyo reservoir watershed were clustered into 2 to 7 clusters and factor analysis was conducted to characterize the water quality, using the information obtained from cluster analysis. The result of cluster analysis shows that Sapkyo reservoir and each stream (Sapkyo stream, Muhan stream and Kokkyo stream) in Sapkyo reservoir watershed hove their own water quality characteristics. The result of water quality analysis indicates that the concentration of suspended solids from Sapkyo reservoir is much higher than those of other streams, and which is probably because of increment of phytoplankton biomass with rich nutrient flowing Into Sapkyo reservoir from the upper stream of watershed. Furthermore, the concentrations of biochemical oxygen demand and chemical oxygen demand were 3.5 to 4.8 times and 1.7 to 2.5 times those of other streams, respectively. The overall water quality of Sapkyo reservoir watershed was considered to exceed eutrophic condition. Based on factor analysis, the water quality characteristics of Sapkyo stream and Muhan stream were closely related with farm land and residence. The water quality of Kokkyo stream was influenced by superabundant organic matter flowing from Chonan city and district wastewater treatment plant located in the upper stream of Kokkyo stream. The water quality factor influencing Sapkyo reservoir was closely related with water quality factors of other three streams.
To establish the mass propagation methods of Weigela subsessilis,, a promising native plant species for horticultural use, several factors influencing rooting from stem cuttings were evaluated. Softwood cuttings showed best rooting rate, 70~77%, in all the cutting media tested, 2.8 times more than hardwood cuttings in which perlite was best medium. The rooting from hardwood cuttings was promoted by higher concentration of all growth regulators used,500 mg.L$^{-1}$ NAA being the best with 80%. More than 80% of softwood cuttings treated by growth regulators produced roots, especially 100, 500, and 1000mg.L$^{-1}$ NAA producing 97%. Roofings from semi-wood cuttings was enhanced by all the growth regulators, except 1000 mg.L$^{-1}$ concentration in which rooting was reduce. Higher rooting rate was obtained by higher concentration and longer soaking duration of NAA in case of hardwood cutting. Softwood cutting showed 100 % rooting by soaking treatment with 500 mg.L$^{-1}$ NAA for 3 min. Rooting rate of semi-hardwood cuttings was promoted by higher concentration and longer soaking with growth regulators, However, the degree of improvement was lower than soft and hardwood cutting.
Purpose: This study investigated the Korean nurses' international migration to provide the basic data for establishing plans of supply and demand for nurses and the status of Korean nurses' application for foreign nurse licenses and overseas employment. Method: The subjects were 5.447 nurses who requested English written nurse license to the Ministry of Health and Welfare for the application of foreign nurse license examinations and overseas employment. Human Resources Development of Korea provided documents of nurses migrated to Saudi Arabia. Data were collected from December, 2002 to July, 2003 and analyzed by using descriptive statistics. Result: The total applicants for foreign nurse license were 3,149 for 2 years. In the year 2001, 1.129 nurses applied, 2,020 nurses in the year 2002. Out of 3,149 total subjects, 2,705(85.9%)nurses applied for U. S. A. nurse license. Eighty percent of the applicants of the U. S. A. nurse license examination applied for the New York states. The number of applicants for Canada was 215(6.8%), followed by Australia 88(2.8%), U. K. 86(2.7%), and New Zealand 45(1.4%). Average age of the applicants was 31, 49.0% of them were in their twenties. Three year college graduates accounted for 64.1% B.S.N. 33.9%. Applicants graduated from universities or colleges of Seoul area were 37.3%, followed by Daegu. The total number of nurses employed overseas were 1,291 during 2001 and 2002. Seven hundred thirty eight nurses(57.2%) were employed in the U. S. A.. Average age was 34, 60.9% were 3year college graduates, nurses graduated from Seoul area were 44.9%. No one applied for Saudi Arabian nurse license, 172 nurses were employed during 1999 and 2002, 39.5% of them were in their thirties. Conclusion: The results of this study shows relatively young and experienced nurses have intention to migrate internationally and they actually migrate to other countries. Comparing the number of nurses migrating to other country with the number of newly issued nurse licenses in Korea every year. the percentage of overseas employment was relatively high. To cope with Korean nurses international migration. new policy to monitor the status of nurse's international migration and an institution to deal with the affairs should be established. And the further study is needed to measure nurse's competence and influencing factors of Korean nurses employed in the U. S. A.
