Purpose: This study intends to clarify the relative importance and character of the college student's attachment to their parents. We examined the effect that the father and mother attachments have en their self-efficacy and adjustment to their college life. Method: The subjects were 271 students who attendee a university. For this study, we used the inventory of the Parent Attachment-Revised version by Armsden and Greenberg, a self-efficacy test by Sherer et al. and the investigation far adjustment to college life by Barker & Siryk. The data were analyzed by t-test, ANOVA, Duncan test and simple multiple regression analysis on an SPSS WIN 10.0 program. Results: There was a significant differences in the attachment to the father according to their grades and in the attachment to the mother according to their type of residence. There was a significant difference in the adjustment to their college life according to their grades. Regression analysis on attachment and self-efficacy suggested that attachment has an influence on self-efficacy. Regression analysis on attachment and adjustment to college life suggested that attachment has influence on the adjustment to college life. Attachment also has an influence on academic adjustment, social adjustment, personal-emotional adjustment and institutional adjustment on the subscale of adjustment to college life. Regression analysis on self-efficacy and adjustment to college life suggested that self-efficacy has an influence on adjustment to college life. Further, self-efficacy has an influence on academic adjustment, social adjustment, personal-emotional adjustment and institutional adjustment on the subscale of adjustment to college life. Conclusion: This study shows that there are relationships among attachment, self-efficacy and adjustment to college life. Especially, self-efficacy is a very important factor influencing the adjustment to college life. So, a plan designed to increase students' self-efficacy should be created based on the results of this study.

Trust is an essential factor in human relations, as it enables man to accept and also disclose self. Today's health care demands nursing personnel with high level of trust . This study was designed and carried out in May through June, 1976 to measure the level of trust on nurses through the trust scale of Nurses (75- N) made by Kenneth et al. and the Parent Inventory made by Rake and to provide data for management of nursing personnel. 150 junior nursing students, 164 professional nurses from 5 universities and their medical centers and 55 nurse- educators from 8 baccalaureate nursing programs in Seoul were randomly sampled. Results are as follows : 1. The rank order of the level of trust revealed that nurse educators the highest and nursing students the lowest. 2. The level of trust revealed to be influenced by the relationship with parents at the early stages of life ; Group who appeared to have shared intimacy with their parents were the highest. 3. Factors such as ; number of siblings and birth order among them, religious affiliation, parental presence revealed to have had no influence on the level of trust in all three group. 4. No significant difference were revealed between the group who had put their names down on the questionnaire and the others. 5. Clinical specialities of practice revealed to have no signigicant influence on trust in nurses. 6. Marital status revealed to have significant influence : in nurses and nurse- educators, the mastered re vented to have significantly higher level of trust. (difference by Recommendations : 1. A study on trust level of patients and Nurses in Nurse- patient Relationship. 2. A longitudinal study to investigate the influence of Nursing education on the development of trust in Nurses are recommended. 3.

The commercially available Amberlite XAD-2 and XAD-4 resins were modified with macrocyclic protoporphyrin IX (PPIX) or tetrakis(p-carboxyphenyl) porphyrin (TCPP) to enhance the adsorption capacity for phenol and chlorophenols. The chemically modified polymeric adsorbents (XAD-2+PPIX, XAD-2+TCPP, XAD-4+PPIX, and XAD-4+TCPP) were applied to the solid phase extraction as an adsorbent material for the preconcentration of phenol and chlorophenols in environmental waters. Generally, the synthesized adsorbents showed higher recoveries than underivatized adsorbents, XAD-2 and XAD-4, without matrix interferences. Especially, XAD-4+PPIX showed more than 90% recoveries for all compounds used in this study including hydrophilic phenol. The major factor for the increase of the adsorption capacity was the increase of $\pi$-$\pi$ interaction between adsorbents and samples due to the introduction of the porphyrin molecule. However, the breakthrough volumes and recovery values of the XADs+TCPP columns were slightly decreased for the bulky chlorophenols such as TCP and PCP. Using molecular mechanics methods, the structures of TCPP and PPIX were compared with that of porphine, the parent molecule of porphyrin. Four bulky p-carboxyphenyl groups of TCPP were torsional each other, thus the molecular plane of TCPP were not on the same level. In conclusion, the decrease of breakthrough volumes and recovery values of XADs+TCPP columns for bulky phenols can be explained by the steric hindrance of the $\pi$-$\pi$ interaction between porphyrin plane and the phenols.

BACKGROUND/OBJECTIVES: Average intake of calcium among college students is below the recommended intake, and knowledge surrounding the attitudinal and behavioral factors that influence milk and dairy intake, a primary food source of calcium, is limited. The purpose of this study was to evaluate college students' attitudes and behaviors concerning milk and dairy consumption and their association with calcium intake. SUBJECTS/METHODS: Participants were 1,730 undergraduate students who completed an online survey (SurveyMonkey) as part of baseline data collection for a social marketing dairy campaign. The online survey assessed attitudes and behaviors concerning milk and dairy intake, and calcium intake. Questions about milk- and dairy-related attitudes and behaviors were grouped into 14 factors using factor analysis. Predictors of calcium intake were then evaluated. RESULTS: Median calcium intake across all participants was 928.6 mg/day, with males consuming higher calcium intakes than females (P < 0.001). Adjusted for gender, calcium intakes were most strongly (and positively) correlated with associating milk with specific eating occasions and availability (i.e., storing calcium-rich foods in one's dorm or apartment) (both P < 0.001). Other correlates of calcium intake included: positive-viewing milk as healthy (P = 0.039), having family members who drink milk) (P = 0.039), and taking calcium supplements (P = 0.056); and negative-parent rules concerning milk (P = 0.031) and viewing milk in dining halls negatively (P = 0.05). CONCLUSIONS: Calcium intakes among college students enrolled in the current study was below the recommended dietary allowance of 1,000 mg/day, reinforcing the need for dietary interventions in this target population, especially females. Practitioners and researchers should consider the factors found here to impact calcium intake, particularly associating milk with specific eating occasions (e.g., milk with breakfast) and having calcium-rich foods available in the dorm room or apartment, as intervention strategies in future efforts aimed at promoting milk and dairy foods and beverages for improved calcium intake in college students.

Based on the case study on the causes for the failure of cutting slope composed of weathered rock and soil, the factors influencing the design of a cutting slope have been examined, This type of rock and soil is widely distributed on the region whose parent rock is granite. To analyze the stability of the cutting slope, the following series of progress has been conducted: (1) ground characterization by geological survey and ground investigation, (2) the safety factor examination by limit equilibrium analysis and numerical analysis and (3) the comparison and analysis of rainfall and failure history. As a result, the main factors to cause the failure is determined to be the decrease of shear strength in the upper parts whose ground condition is weakened during localized heavy rain. Moreover, the analysis indicates the failure is also closely related to the groundwater inflow path. On the base of this investigation, a reinforcement method is proposed to ensure the stability of the cutting slope.

Various angiogenesis inhibitors target vascular endothelial cells and block tumor angiogenesis. Angiostatin is a specific endogenous angiogenesis inhibitor in clinical trials, which contains only the first four triple loop structures, known as kringle domains. Its generated by proteolytic cleavage of its parent molecule plasminogen, which itself does not exhibit antiangiogenic activity. Kringle domains from prothrombin, apolipoprotein, hepatocyte growth factor, urokinase and tissue-type plasminogen activator also elicit anti-angiogenic or antitumor activities in several model systems, albeit low amino acid sequence identity between angiostatin and each individual kringle. However, the differential effects of each kringle domain on endothelial cell proliferation, and migration observed in these kringle domains, suggest that the amino acid sequence of the primary structure is still important although kringle architecture is essential for anti-mlgiogenic activity. If it is further studied as to how amino acid sequence and kringle architecture contributes in anti-angiogenic activity, with studies on underlying mechanisms of anti-angiogenesis by kringle-based angiogenesis inhibitors, it will provide basis for the development of new potent anti-angiogenesis inhibitors and improvement of the efficacy of angiogenesis inhibitors.

(1'R, 2R)-, (1'R, 2S)-, (1'S, 2R)- and (1'S, 2S)-$\alpha$-hydroxymetoprolol; (2R)- and (2S)-O-des-methylmetoprolol; and (2R)- and (2S)-metoprolol acid are major metabolites of (2R)-and (2S)-metoprolol, $\beta$-adrenergic antagonist. The focus of most chiral separation methods until now has been on determination of the enantiomeric parent drug. However, it is just as important to be able to follow the metabolism of the enantiomers and their possible chiral metabolites. Therefore, for the study of stereoselective metabolism and pharmacokinetics of metoprolol, the chiral separation of the enantiomers of metoprolol and its metabolites has been investigated using four chiral stationary phases, i.e., Chiralcel OD, Chiral-AGP, Cyclobond I and Sumichiral OA-4900 columns. Metoprolol acid was resolved only by Sumichiral OA-4900. Chiralcel OD provided the highest separation factor and resolution value for metoprolol and O-desmethylmetoprolol and partially resolved the four stereoisomers of $\alpha$-hydroxymetoprolol. Diastereomeric $\alpha$-hydroxymetoprolols were resolved using the coupled column chromatographic system of two chiral stationary phases, Sumichiral OA-4900 column and Chiralcel OD column.

It is important to identify the contaminant sources and to evaluate the fate and transport of heavy metals to crops in agricultural lands. This study was conducted to evaluate metal sources and its transfer and accumulation to crop in agricultural soils. Pollution indices were calculated and multivariate analysis was performed to identify metal sources. To evaluate transfer and accumulation of metals to crops, the contents of phytoavailable metals were evaluated by using single extraction method and the correlation between metal content and soil properties was analyzed. Also the BCF was quantitatively evaluated for investigating the metal transition to each crop grown in the research area. As a result, Cr, Ni, and Co were expected to be mainly derived from geologic factors due to weathering of certain parent rocks. The content of nickel in soils of the research area was slightly higher than that of the concern level criteria based on total concentration, but the amount transferred and accumulated in the crops was actually low. Understanding the contamination characteristics by investigating the pollution sources of heavy metals and its transfer and accumulation to crops through various evaluation techniques could provide important information for proper management of the agricultural land.

This study aims to provide basic resources for the construction of the archives on the official family service history in Korea. The study collected records of family policies and official family service from 1948 to 2019 and thereafter attempted to classify the official family service. In addition, experts were consulted to diagnose compliance with research contents and directions, investigate priorities of the family policies, and provide opinions on the elements of each process of archiving. The results of this study were as follows. First, there were five areas of concern to be considered in the process of establishing an archive of official family services: concept, scope, collection, arrangement, preservation, and utilization. Second, the findings suggest which processes are critical to developing a sustainable and systematic archive system for the official family service history. The construction of the archives will provide a platform for understanding the contents of integrated family policies and inform the direction of future family policies in Korea. In addition, these archives will be an important factor in building a solid Korean national identity.
