The purpose of this study is to explore into the Korean Women's sexual life in terms of sexual behavior, sexual attitudes, and sexual experiences. In recent years, it has been generally recognized in both academic area and general publics that traditional norms, values, and patterns of behavior have been rapidly changing in Korea, thus being replaced by new ones. 1. The prevailing preconception that Korean women are sexwise traditional and conservative seems to be no longer true in the present days. 2. In this country, their sexual behaviors and attitudes at least within their marriage have been already westernized, being very similar to those of western women. 3. Knowledge and information of sexual matters held by Korean women prior to their marriage seems to be very limited, compared to those of western women. 4. It seems that Korean women have developed positive attitudes toward sex education practice in their family.

In this study, we tried to understand preschooler clothing trends and identify the purchase behaviors of various consumers, such as grandparents, aunts, uncles, and parents, who are the main consumers of the preschooler clothing market. We conducted in-depth interviews with consumers who were interested in preschooler clothing, purchased it frequently, and bought preschooler clothing within the last three months. Their purchase motivations and purchase behaviors were analyzed through exploratory and inductive analysis. The analysis was conducted by integrating categories into one process centered on core categories through open coding, axial coding, and selective coding. The results of this study included that 1) a variety of clothing purchase behaviors appeared as a central phenomenon, 2) the causal conditions that contributed to this phenomenon were the buyers' childcare experiences, purchase experiences, the personal consumption values of individuals, and income levels, 3) in response to the central phenomenon, the parents' action/interaction strategies were acceptance and rejection of purchased clothing, 4) contextual and Intervening conditions affecting action/interaction strategy were family environment changes, the VIB (Very Important Baby) phenomenon, parents' clothing involvement, and the relationship with the buyers, and acceptance by the users, and 5) as a result of the strategy expressed as acceptance and rejection, various clothing behaviors emerged. In this study, we identified that there are various influencers, apart from parents, involved in children's clothing consumption. Therefore, we need to keep in mind that various purchase behaviors and clothing trends that appear during one's childhood may affect the individual's clothing behavior in the future.

Objectives: The purpose of this study was to investigate the basic grounds for the policies of health promotion on the elderly by analyzing lifestyle. Methods: This study recruited 500 seniors aged over 65 years participating in exercise programs for the elderly provided by four branch offices of NHIC in Daegu. Results: 'Ideal type' was a group thinking that exercise programs for the elderly made their life healthy and energetic and living a happy life and 'social type' was a group answering that they helped to manage their health condition and to relieve stress and activated relationship with family members and friends to gain self-confidence. ‘Passive type’ and 'lethargic type’ said that the programs did not influence their life overall. Conclusion: Entrance into an aging society has changed values of the elderly. Their lifestyle becomes various and the effect of exercise programs for the elderly was also different according their lifestyle. Therefore, exercise programs considering lifestyles of the elderly will maximize their effect.

This paper reviews researches related with the elderly caregiving, which hale published during the 1990s. After analyzingthe 29 articles in this field, the major findings are as follows: First, the advantageous position in life chances which is consisted of socioeconomic status and resources tends to reduce th burden for the elderly care. The higher in social status, the more resources older adults have, the more advantageous in controlling their relationship with their children and caregivers. Second, values based on familism is more associated with providing caregiving services for their parents than those of filial piety. Third, the tendency that daughter-in-law takes the role of the primary caregiver suggests a possibility of diminishing her enthusiasm, and finally comes to recognize her role as an enforced one, as time goes by. Fourth, cargiving burden affects the diverse aspects of caregiver's way of life. When the lower class elderly has dementia, caregiving stress and hassle have reached at their peak level. For meeting the needs of reducing the burden for the elderly care, this study suggests community- based approach for the elderly care. This approach attempts to share the caregiving burden with local community. To share the burden means that the boundaries of caregivers does not limit family members, but to expand community. This attempt includes a plan that establishes multipurpose community center which provides comprehensive services and care for the aged. The theoretical rationale of this approach are also discussed.

Polycrystalline $Sr_2Nb_2O_7$ ceramics with very high Curie temperature were sintered using the powder derived by the chemical coprecipitation method (CCP). The phase evolution and grain-orientation of sintered samples were examined by XRD, while sintering behavior, dielectric properties and polarization were studied by SEM and ferroelectric tester. Extremely high degree of grain-orientation was observed along the (0k0) direction, which resulted in anisotropic dielectric properties of the sintered samples, with the dielectric constant values approaching those for single crystal. Thin film fabrication of $Sr_2Nb_2O_7$ in the pyroniobate family was also attempted on $SiO_2$/Si(100), Pt/$SiO_2$/Si(100), Pt/Ti/$SiO_2$/Si(100) and Pt/$ZrO_2/SiO_2/Si_2(100)$ substrates, using metalorganic decomposition (MOD) process. Neodecanoate precursor solution was prepared by mixing strontium neodecanoate with niobium neodecanoate synthesized from niobium ethoxide. It was found that $Sr_2Nb_2O_7$ single phase appeared in XRD patterns the samples annealed above $950^{\circ}C$. The effect of substrate type on film microstructure and dielectric properties was observed.

A surface plasmon resonance (SPR) sensing system, which belonged to a family of thin film refractometry-based sensors, was fabricated to measure the alcohol contents in alcoholic beverages. In this study, a SPR owe was obtained by a photodiode array with 128 pixels and transformed into a refractive index which was calculated by means of the first moment of values below a baseline of 0.85. When the sensing system was applied to Soju, Cheonju, Igwaduju and Tacju highly linear relationships between the refractive index by SPR and the contents of alcohol were obtained. That is, the coefficients of determination in their linear models were 0.992, 0.933, 0.918 and 0.954, respectively. Meanwhile, the effect of sample preparations on the accuracy of measurement was analyzed. As for Soju and Tacju, the best calibration equations were obtained when no sample preparation was applied. The best calibration models for measurement of Cheonju and Igwaduju were obtained through the samples filtered by $C_{18}$ disks.

The two dimensional quantitative structure-activity relationships (2D-QSARs) models concerning the binding affinity constants ($p[Od.]_{50}$) between 2-cyclohexyltetrahydropyrane and 2-cyclohexyltetrahydrofurane analogues as substrates, and bovine odorant binding protein (bOBP) as receptor were derived by multiple regression analyses method and discussed. The statistical quality of the optimized 2D-QSAR model (5) was good (r=0.907). From the model, the binding affinity constants ($p[Od.]_{50}$) were dependent upon the optimal value ($(TL)_{opt.}$=2.737) of total lipole (TL) of substrate molecules. Based on these findings, the high active compounds predicted by optimized 2D-QSAR model (5) were 2-(dimethylcyclohexyl)tetrahydropyrane molecule and their isomer molecules. The binding affinity constants regarding bOBP of the tetrahydrofuryl-2-yl family compounds were dependent upon the hydrophobicity (logP) of whole substrate molecules. In any case of porcine odorant-binding proteins (pOBP), the constants were dependent upon the hydrophobicity (${\pi}x={\log}P_X-{\log}P_H$) of substituents (R) in substrate molecules. Also, from the optimal values of hydrophobic constant, the hydrophobicity for bOBP influenced ca. twice time bigger (bOBP>pOBP) than that for pOBP.

Cupin-superfamily proteins represent the most functionally diverse groups of proteins and include a huge number of functionally uncharacterized proteins. Recently, YaiE, a cupin protein from Escherichia coli has been suggested to be involved in a novel activity of pyrimidine/purine nucleoside phosphorylase (PPNP). In the present study, we achieved a complete backbone NMR assignments of YaiE, by a series of heteronuclear multidimensional NMR experiments on its [$^{13}C/^{15}N$]-enriched sample. Subsequently, secondary structure analysis using the assigned chemical shift values identified 10 obvious ${\beta}-strands$ and a tentative $3_{10}-helix$. Taken all together, the results constitute the first structural characterization of a putative PPNP cupin protein.

In recent years, there is remarkable tendency of overconsumption and high calorie intake which may come from a high availability of foods, the increase of food production, processed food, and imported food. This cause chronic diseases such as obesity. high blood pressure inducing heart disease, and diabetics etc. Traditional Korean eating pattern and habit make too much waste of foods and wasting time for the food preparation. The dietary guideline used for the guidance of Korean diet pattern is composed of 'nutrients-ingredient-cooking-meal which is not visualized pattern. Therefore we made up menus in the pattern of meal-cooking-ingredient-nutrient, which is more brief, compact and more visualized pattern. We set 27,000 menus with 600 kcal/meal which is combined with staple meal-main dish-side dish (30 menus of rife meal, 5 menus of bread meal, noodle meal and one serving dish meal). 600 kcal menu is basically for volume of serving per one person according to the experimental cooking and reference. This has several advantages of simple procedure of cooking, easy practice to use menus, and good source of nutritional values. In addition to these, it also provides a new menu to decrease the calorie consumption reducing the risk of chronic disease, to prevent wasting foods, and to help single person.

Purpose: The purpose of this study was to identify university students' willingness to write advance directives and factors related to this willingness. Method: A cross-sectional survey design was used and 400 nursing students and 287 non-nursing students participated in the study. Data were collected by convenience sampling using self-report questionnaires. Data were analyzed with descriptive statistics, t-test, ANOVA, correlation, and multiple regression. Results: The mean score for willingness to write advance directives was 4.09. From the multiple regression analysis, predictors of willingness to write advance directives were found to be majoring in nursing, awareness of advance directives, preference for autonomous decision making related to the end of life care, family preference related to the end of life care, and self esteem. Conclusion: The study results indicate that various factors are related to willingness to write advance directives and nurses need to consider client characteristics, knowledge, and own values when taking care of issues on advance directives.
