It is possible to explain the design, the meaning, and the use of domestic space by comparing different cultures. The characteristics of Koreans' housing life living in western cultures has already been studied extensively. Because of political reasons, however, the characteristics of Koreans' housing life living in Chinese culture has hardly been studied at all. The purpose of this study was to find out the characteristics of succession and transformation of domestic housing culture. The data was collected by questionnaire methods from fifty Korean households and eleven Chinese households. Individual interviews and actual surveys, including taking pictures were also used for data collection. The results of this study were as follows (1)An analysis of heating system usage behaviors showed the importance of heated floors, known as Ondol, is one of the enduring characteristics of domestic habits. (2)In the sitting style, the traditional sitting on the floor was shown in living room. (3)Regarding room usage behavior, Korean households were centered around the living room in chinese houses. (4)An analysis of space organization preferences with respect to common spaces revealed that Korean households tend to prefer the open plan of common spaces.

Fish extracts were processed at high temperature (136.7 ~14$0^{\circ}C$) for possible use as functional food ingredients. Raw fish meats and those hydrothermal extracts were compared with respect to in vitro and in vivo protein qualities. 95% of fat inraw meats was reduced in extracts but there were not remarkable changes in other macronutrients in freeze-dried extracts. Most of essential amino acids were decreased significantly but two times more proline and glycine were detected in extracts. High temperature cooking resulted 2.1 ~3.7 times of higher total free amino acid content infish extracts compared iwth raw meat, and taurine and glutamic acid were increased especially. Severe protein damages were occurred when invitro protein quality indices such as availblae lysine, hydrophilic browing, trypsin inhibitor formation and in vitro protein digestibility were measured on fish extracts. In vivo protein qualities were also strongly influenced by high temperature ; however rat-body-weight gain was nearly zero during PER assay, and rat PER or NPR of fish extracts were significantly lower (p<0.001) than those of cotnrol (ANRC casein) and original raw fish meats.

Thirty populations of Chondrus crispus Stackhouse from Nova Scotia were collected during the years 1993 to 2011. Taken from estuaries, wave exposed open coasts, high intertidal rock pools and shallow subtidal habitats, the populations were evaluated for relative abundance of tetrasporophytic and gametophytic life history phases. Over 2,800 thalli were characterized using the resorcinol-acetal test to distinguish the kappa- and lambda-carrageenan containing fronds of gametophytes and tetrasporophytes, respectively. These populations had $77{\pm}5%$ gametophytes (mean ${\pm}95%$ confidence interval), with most populations having gametophyte : sporophyte ratios ranging from 2 : 1 to 9 : 1. No population had a dominance of tetrasporophytes, although two populations had 1 : 1 ratios. A meta-analysis of our data along with previously published accounts showed no significant changes in gametophyte dominance with respect to hypothesized gradients of wave exposure, salinity, or water depth. Significant changes occurred in ratios at five sites where replicate sampling occurred in different years. We conclude that C. crispus in Maritime Canada has a natural ratio of 3 : 1 or greater in stable conditions, and that lower ratios represent recovery from disturbance in which bare substratum is created that is subsequently colonized by carpospores from remaining gametophytic thalli.

Barley proteins are expected to have unique functional properties due to their high content of alcohol soluble protein, hordein. Since the barley proteins obtained by conventional isoelectric precipitation method cannot represent hordein fraction, barley proteins were fractionated to albumin, globulin, glutelin, and hordein with respect to extraction solvents. Functional properties and film-forming properties of solubility-fractionated barley proteins were investigated to explore their potential for human food ingredient and industrial usage. The 100 g of total barley protein comprised 5 g albumin, 23 g globulin, 45 g glutelin, and 27 g hordein. Water-binding capacities of barley protein isolates ranged from 140-183 mL water/100 g solid. Hordein showed the highest oil absorption capacity (136 mL oil/100 g), and glutelin showed the highest gelation property among the fractionated proteins. In general, the barley protein fractions formed brittle and weak films as indicated by low tensile strength (TS) and percent elongation at break (E) values. The salt-soluble globulin fraction produced film with the lowest TS value. Although films made from glutelin and hordein were dark-colored and had lower E values, they could be used as excellent barriers against water transmission.

The Supreme Court made a decision that the doctor cannot be punished for not taking a blood transfusion to the patient, depending on the patient's will to refuse the blood transfusion on June 24, 2014. The reason is that, in a special situation of conflict between the right of patients to self-determination and the duty of care, and when it was impossible to compare whether which has the superior value, if the doctor made a medical practice to respect either of those two values according to the professional sense, he cannot be punished. In principle, the doctor should make medical practices according to the patient's will. However, if the patient's life was at stake, I think, the doctor is obliged to try his best to save the life of patient. Yet to entrust the patient's life to the doctors professional sense, is to give up the obligation of the country to protect lives. In this regard, I think that the Supreme Court Decision should be reviewed, and that an ongoing research is needed.

Purpose: The purpose of this review was to identify the current status of nursing studies on heart failure (HF) patients in South Korea and to suggest future study direction. Methods: A literature review of databases such as KoreaMed, KERIS and nursing and allied health journal were searched with key terms 'heart failure' and 'nursing' for the period from January 2000 to February 2017. A total of 35 studies including 28 articles and 7 theses met the inclusion criteria. Results: Twenty-seven out of 35 studies were observational studies on outpatients and most of the studies did not mention the ejection fraction and New York Heart Association functional classification class (NYHA class) in the inclusion criteria. Self-care and health-related quality of life as psychological factors, and physical activity as a biological factor, were used as main variables. However, we found it difficult to understand how much score indicates better quality of life because of an inconsistent and wide score. In quality assessment, 8 intervention studies had no serious flaws. Conclusion: Further studies should consider more biological and social factors influencing HF. The quality assessment with respect to nursing intervention studies in HF showed that randomized and double-blind trials are needed.

The effects of antimetabolite 6-AN (6-amino-nicotinamide) on viability and morphology of L6 myoblast cells have been investigated. 6-AN ($100{\mu}M$) induced a time-dependent decrease in cell viability with respect to the untreated control cells. Following 6-AN administration the viability rate started to decline sharply, reaching about 23% of the untreated control cells at 48 h. Inverted phase-contrast microscopy revealed that 6-AN caused characteristic morphological changes such as irregularly elongated and stellate shape of cells, round-shaped nucleus, cytoplasmic vacuolization, irregular cell arrangements and formation of large spaces among cell clusters. The concentrations of ATP and $NAD^{+}$ in the 6-AN treated cells were significantly lower (p < 0.01) than those of the untreated control cells. In contrast, the concentration of AMP was significantly increased by the 6-AN treatment. Activities of catalase, superoxide dismutase and glutathione peroxidase in 6-AN treated cells were significantly higher (p < 0.01) than those of the untreated control cells. The activities of glyceraldehyde-3-phosphate dehydrogenase in 6-AN treated cells were significantly lower (p < 0.01) than those of the untreated control cells. The results suggest that 6-AN caused marked reduction of cell viability and alterations of some important metabolites and enzymes.

Purpose: The aim of this study was to examine the correlation between school-life adjustment and suicidal ideation in adolescents by applying the latent growth curve models to the longitudinal data. Methods: This study analyzed three waves of data from the Korean Children & Youth Panel Survey (2014~2016). A total of 1,534 students were included in the analysis. In the application of the latent growth curve models to the longitudinal survey data, we analyzed the initial status and growth changes for each wave, identified individual differences in the general characteristics, and examined the direct relationship between the two latent constructs. Results: The analysis revealed that variations in the initial status and rate of school-life adjustment were significant with respect to parents' education level, household income and academic satisfaction. Variations in the initial status and growth rate of suicidal ideation were significantly associated with household income and family structure. The relationship between school-life adjustment and suicidal ideation showed a negative correlation in which the starting value of the former increased and that of the latter decreased and vice versa. Conclusion: The results confirmed that school-life adjustment and suicidal ideation varied according to students' general characteristics. In addition, school-life adjustment was negatively correlated with suicidal ideation, thereby highlighting students' ability to adjust as an important factor influencing their suicidal thinking.

This study aimed to examine Korean men's experiences of work-family balance in dual income families with children under six years of age. We focused on identifying the difficulty of balancing work and family considering their individual, social, and cultural conditions. The method was a qualitative study involving two in-depth interviews with each of 12 men, and analyzing the data through the grounded theory approach. From the results, a model of men's work-family experience was constructed. It demonstrates the central phenomena (difficulties of balancing), the causal conditions (lacking time for family, seeking support from the employer, and learning husband's roles insufficiently), the contextual conditions (remaining paternalism and changing husband's roles), the intervening conditions (workplace, childcare support, and wife characteristics), and strategies (help from relatives, utilizing daycare centers, controlling birth, managing work conditions, and using family polices). We clarify the overall picture of working and family life experiences, and also show how men deal with their problems in their circumstances by balancing working and family life. In conclusion, males have difficulty participating in family life autonomously because of having less decision-making power than the wife. Moreover, the great responsibilities of the breadwinner disturb the work-family balance. Men devote themselves to working to hold a job instead of spending time with their family. However, they ultimately value work-family balance with respect to 'keeping a peaceful family life'.

The purpose of this study was to examine the effects of Adlerian Community Feeling Program on the school life satisfaction and depression among elementary school students. Subjects were 38 students who were the fifth grader students and all participants were asked to complete the school life satisfaction scale and depression scale. The pretest and posttest were implemented in order to verify the effectiveness of the program. The program consisted of a total 9 sessions, focusing on building the relationship, self-acceptance, respect for others, cooperation and contribution. The employed statistical analysis was ANCOVA. The results of the study are as follows: First, the Community Feeling Program had an influence on significant improvement in school life satisfaction and its sub-factor, general classes, teacher-student relationships and the physical environment of a school. Second, the Community Feeling Program had an influence on significant effect in depression and its sub-factor, negative mood/physical symptom. Thus, the Community Feeling Program based on Adlerian Psychology has been found to be effective in improving overall school life satisfaction and reducing depression.
