Titin-cap (TCAP), one of the abundant transcripts in skeletal muscles, was nvestigated in this study in cattle because of its role in regulating the proliferation and differentiation of myoblasts by interacting with the myostatin gene. From the 5, and 3, RACE experiments, full-length TCAP coding sequence was identified, comprising 166 amino acids. The amino acid comparison showed high sequence similarities with previously identified human (95.8%) and mouse (95.2%) TCAP genes. The TCAP expression, addressed by northern blot, is limited in muscle tissues as indicated by Valle et al. (1997). The radiation hybrid analysis localized the gene on BTA19, where the comparative human and porcine counterparts are on HSA17 and SSC12. A few muscle-related genetic disorders were mapped on HSA17 and some growth-related QTLs were identified on SSC12. The bovine TCAP gene found in this study opens up new possibilities for the investigation of muscle-related genetic diseases as well as meat yield traits in cattle.

This study proposed a plan to seek a more practical way of life norm education of today's families on the basis of family rule in the traditional society by comparison between the older generation's family life rule education and college students. The study was made by analysing rules in Chosun Dynasty questionaire nair was drawn up on the basis of it. The subjects of this study were college students of one largest cities and their 800 parents. Collected data was processed by frequency analysis, ANOVA, interrelation and regression which are used through SPSS computer programs, Study results show that acceptance level is higher among the older generation but the necessity of family standare education is urgent beyond the generations. Also people who have lived with grand parents feel more necessity of education family norm. When the education could not be made in families because parents excessive protection examination-centered education, and bad effects of mass media then emphasis has to be made to create life culture which makes family norms to be kept continuously by the education at schools, education culture centers and public facilities.

Objective: This study was performed to compare fat content, reducing sugar contents, sensory traits, and fatty acid (FA) and volatile compound profiles in longissimus thoracis (LT) among Korean cattle (KC), Holstein (HO), and Angus (AN) steers. Methods: Twelve LT samples (about 500 g each) of KC with an average age of $31{\pm}0.42months$, an average carcass weight of $431{\pm}12.5kg$, and a quality grade (QG) of 1+ were obtained from the joint livestock products market. Twelve LT samples of HO cattle with an average age of $24{\pm}0.54months$, an average carcass weight of $402{\pm}7.81kg$, and a QG of 2 were also obtained from the same market. Twelve LT samples of AN steers with an average age of about 20 months and a QG of choice were purchased from a beef delivery company. After slaughter, samples were kept at $4^{\circ}C$ for 42 days and prepared for immediate analysis or stored at appropriate conditions. The chemical composition, color, pH, shear force, collagen content, reducing sugars, sensory evaluation, FA composition, and volatile compound content for each LT sample were analyzed. Results: The LT of KC had the highest (p<0.05) fat content, the highest reducing sugar content, and the highest scores in the sensory evaluation (flavor, tenderness, juiciness, and overall acceptance). All the sensory traits were positively correlated (p<0.001) with intramuscular fat and reducing sugar content. Several FAs and volatile compound profiles varied among the breeds. KC LT had the highest (p<0.05) concentrations of acetaldehyde, 3-methyl butanal, and 3-hydroxy-2-butanone, and these volatile compounds were positively correlated (p<0.05) with all the sensory traits. Conclusion: Variations in fat content and reducing sugar contents and FA and volatile compound profiles may contribute to differences in the sensory quality of LT among breeds.

Purpose: The aim of this study was to compare the factors of health-related quality of life in older adults according to the type of residency. Methods: A cross-sectional comparative study was conducted. The subjects were 114 institutionalized older adults and 99 community dwelling older adults. Data were collected through face-to-face interviews by nurses using structured questionnaires composed of SF-36 (ver.2) and CGA-SF. Results: The institutionalized older adults had more health problems and experienced lower quality of life compared to community dwelling older adults. Factors influencing health-related quality of life for institutionalized older adults were social support, educational level, and ADL, which explained about 25.7% of the total variance, while thoseof community dwelling older adults were IADL, experiencing fall, and weight loss, which had explanatory power of 31.8%. Conclusion: These results indicate that differentiated nursing strategies according to the type of residency are required to promote health-related quality of life for older adults.

Objectives This study aimed to evaluate the relationship between residential district of people, such as power plant, steel-mill and petrochemical industries, and health-related quality of life (HRQoL). Methods Using a cross-sectional study design, we randomly recruited participants for our study from industrial areas (thermoelectric power plant, steel-mill, petrochemical industry) and rural areas. Logistic regression analysis was used to identify the relationships between Euro quality of life-5 dimension (EQ-5D) scores and living region, while controlling for sociodemographic characteristics. Results In adjusted model, quality of life decreased with increasing category of age and were lower for females than males. EQ-5D scores of people living in the vicinity of thermoelectric power plant were significant lower than those of people living the vicinity of comparison region (odds ratio, 1.59; 95% confidence interval, 1.00 to 2.53). Conclusions Living region of thermoelectric power plant, was strongly associated with scores on the EQ-5D. More research is needed to elucidate the mechanisms which makes the relationship with the living regions and HRQoL.

For the purpose of the comparative environmental estimation of the incineration processes for domestic wastes, environmental impacts for several incineration processes for one ton of domestic wastes have been estimated by employing life cycle assessment as the environmental impact assessment method. The scheme of minimum production of environmental pollutants has been considered for three different incineration processes. The evaluation for latent influence on environment was carried out by using CML(Center of Environmental Science) method which was developed by University of Leyden in Netherlands based on the equivalency factor suggested by Korea Accreditation Board. The result of life cycle assessment has showed that the total cost analysis according to the amount of incinerating waste was dependent on the operating conditions of incineration process. In addition, the annual running cost for the incineration of one ton of wastes was estimated to be negatively dependent on the amount of wastes. The degree of environmental pollution was mainly due to the kinds of the wastes rather than by the amount of wastes.

Objective: The study was conducted to investigate variations in the immunophysiological responses to exercise-induced stress in Jeju and Thoroughbred horses. Methods: Blood samples were collected from the jugular veins of adult Jeju (n = 5) and Thoroughbred (n = 5) horses before and after 30 min of exercise. The hematological, biochemical, and immunological profiles of the blood samples were analyzed. Blood smears were stained and observed under a microscope. The concentration of cell-free (cf) DNA in the plasma was determined using real time polymerase chain reaction (PCR). Peripheral blood mononuclear cells (PBMCs) and polymorphonuclear cells were separated using Polymorphprep, and the expression of various stress-related and chemokine receptor genes was measured using reverse transcriptase (RT) and real-time PCR. Results: After exercise, Jeju and Thoroughbred horses displayed stress responses with significantly increased rectal temperatures, cortisol levels, and muscle catabolism-associated metabolites. Red blood cell indices were significantly higher in Thoroughbred horses than in Jeju horses after exercise. In addition, exercise-induced stress triggered the formation of neutrophil extracellular traps (NETs) and reduced platelet counts in Jeju horses but not in Thoroughbred horses. Heat shock protein 72 and heat shock protein family A (Hsp70) member 6 expression is rapidly modulated in response to exercise-induced stress in the PBMCs of Jeju horses. The expression of CXC chemokine receptor 4 in PBMCs was higher in Thoroughbred horses than in Jeju horses after exercise. Conclusion: In summary, the different immunophysiological responses of Jeju and Thoroughbred horses explain the differences in the physiological and anatomical properties of the two breeds. The physiology of Thoroughbred horses makes them suitable for racing as they are less sensitive to exercise-induced stress compared to that of Jeju horses. This study provides a basis for investigating the link between exercise-induced stresses and the physiological alteration of horses. Hence, our findings show that some of assessed parameters could be used to determine the endurance performance of horses.

The well-conserved NBS domain of resistance (R) genes cloned from many plants allows the use of a PCR-based approach to isolate resistance gene analogs (RGAs). In this study, we isolated an RGA (CapRGC) from Capsicum annuum "CM334" using a PCR-based approach. This sequence encodes a protein with very high similarity to Rx genes, the Potato Virus X (PVX) R genes from potato. An evolutionary analysis of the CapRGC gene and its homologs retrieved by an extensive search of a Solanaceae database provided evidence that Rx-like genes (eight ESTs or genes that show very high similarity to Rx) appear to have diverged from R1 [an NBS-LRR R gene against late blight (Phytophthora infestans) from potato]-like genes. Structural comparison of the NBS domains of all the homologs in Solanaceae revealed that one novel motif, 14, is specific to the Rx-like genes, and also indicated that several other novel motifs are characteristic of the R1-like genes. Our results suggest that Rx-like genes are ancient but conserved. Furthermore, the novel conserved motifs can provide a basis for biochemical structural. function analysis and be used for degenerate primer design for the isolation of Rx-like sequences in other plant species. Comparative mapping study revealed that the position of CapRGC is syntenic to the locations of Rx and its homolog genes in the potato and tomato, but cosegregation analysis showed that CapRGC may not be the R gene against PVX in pepper. Our results confirm previous observations that the specificity of R genes is not conserved, while the structure and function of R genes are conserved. It appears that CapRGC may function as a resistance gene to another pathogen, such as the nematode to which the structure of CapRGC is most similar.

Objectives : This study compared the influencing factors on life satisfaction after retirement between public pension and specific corporate pension recipients. Methods : This study used the fifth year data of 2013 from the raw data of the Korean Retirement and Income Study collected by the National Pension Research Institute. The data analysis in this study was done with the chi-square test, t-test, and linear regression using SPSS ver. 22.0 to verify the relevance between the general characteristics of pension recipients. Results : This study shows that there was a difference in expenditures and health care costs between public pension and special corporate pension recipients. The influencing factors on life satisfaction for public pension recipients were the level of spending, whether there were limitations in daily life and social activity, whether recipients had financial assets and health care costs while for specific corporate pension recipients, they were education level, level of spending and chronic diseases. Conclusions : A health policy that maximizes life satisfaction and takes into account the type of pencion needs to be considered and implemented.

Objectives: The primary objective was to test the phenomenon known as the insight paradox, which refers to the association between higher levels of insight and lower self-esteem, higher hopelessness, and a higher perception of social prejudice among patients with schizophrenia. Methods: A total of 216 outpatients with schizophrenia according to the DSM-IV diagnostic criteria were recruited. All participants were receiving ongoing outpatient treatment and were in a stable phase of the disorder. The participants were divided into a good-insight (N=109) and a poor-insight (N=107) group by the direct interview and the mean score of questionnaire. The parameters used for analysis and comparison were demographic variables (age, gender, education), clinical variables (age at onset, number of hospitalizations), self-esteem, hopelessness, self-stigma, and quality of life. Results: Compared with the poor-insight group, the good-insight group was found to have a lower number of hospitalizations, lower self-esteem, higher hopelessness, lower quality of life, and a higher level of internalized stigma. Conclusion: The insight can cause the negative consequences in patients with schizophrenia. Therefore, clinicians should pay attention to the negative aspects of insight for improving the quality of life in the treatment of patients with schizophrenia.
