Purpose: The purpose of this study was to identify differences in Health Locus of Control (HLOC), depression, wellbeing, and Health Promoting Lifestyle Profile II (HPLP) between middle aged Korean and Korean-American women. Methods: Data from 80 Korean-American women living in Los Angeles, USA and 82 Korean women living in W-city, Korea, were collected using a self administered questionnaire including items on HLOC, HPLP, a Wellbeing Index and Major Depression Inventory. Results: There were statistically significant differences between the middle aged Koreans and Korean-Americans on mean age, education, religion, and current health insurance. Significant differences were found on HLOC (F= 2.504, p=.033) and Wellbeing (F=2.451, p=.036). The results also showed significant differences on HPLP (total HPLP, F=4.655, p=.001; physical activity, F=2.967, p=.014; nutrition, F=4.250, p=.001; spiritual growth, F=4.398, p=.001; interpersonal relations, F=2.648, p=.025; and stress management, F=5.201, p<.001) using ANCOVA. However, there were no significant differences on depression, or health responsibility in HPLP between the groups. Conclusion: Understanding middle aged women's health adjustments based on their culture will enhance the ability of health professionals to provide culturally congruent care and enable middle aged women to develop healthy lifestyles.

Since the enactment of the "Framework Act on the Korean Language (herein after "Act ), researchers have focused their studies on measuring whether the Act played a huge role in providing Korean education. This can be confirmed by many, that the Act has indeed played a huge part in providing Korean language education. However, little attention was given to the validity of the education curriculum for prospective Korean language teachers as provided by the Act. Therefore, this survey has been conducted to provide an insight to teachers' perception of the Korean language curriculum for prospective teachers and will test whether such perception meets the standards in which the Act has been enacted. In this survey, we have received response on the importance of each domain and subject in the areas of Korean language education as viewed by the Korean language teachers. The results revealed the importance in the following order: Teaching Practice, Korean Linguistics, Korean Educational Linguistics, General Linguistics, and Korean Culture. These results strongly suggest that there is a need for the current curriculum, laid out by the Act, to be reconsidered to stress different levels of importance and time assignment for each category. The survey analysis shows the disparity in importance within the curriculum between the Act and the views in which the Korean language teachers perceive Korean language education. While further research is needed to confirm the analysis of this survey, this area of research will be instrumental in determining the suggestive shapes of the curriculum governed by the Act in the years to come.

GABA (γ-aminobutyric acid) has various beneficial effects on human health such as anti-hypertension, diuretic, tranquilizer, sleep induction and anti-stress functions. In this study, the properties and the antioxidizing effects of a fermented solution was investigated by applying GABA producing lactic acid bacteria (LAB) from kimchi to corn silk extract. Lactobacillus plantarum LAB459 was identified by physiological properties, carbohydrate fermentation pattern and 16s rRNA sequence analysis. Also, the GABA production ability of the separated L. plantarum LAB459 was confirmed through TLC and HPLC analysis. Moreover, from the fermentation of corn silk extract with skim milk, it was revealed that approximately 1 ㎍/mg of GABA produced by lyophilized ferments was yielded. Lastly, the flavonoid content and DPPH radical scavenging activity were found to be high in the lyophilized ferments than in the aqueous extracts. Therefore, L. plantarum LAB459 is considered to be used as a starter culture for various fermented foods or in food and medicinal materials.

OCT4, also known as POU5F1 (POU domain class 5 transcription factor 1), is a transcription factor that acts as a master regulator of pluripotency in embryonic stem cells and is one of the reprogramming factors required for generating induced pluripotent stem cells. The human OCT4 encodes three isoforms, OCT4A, OCT4B, and OCT4B1, which are generated by alternative splicing. Currently, the functions and expression patterns of OCT4B remain largely unknown in malignancies, especially in human glioblastomas. Here, we demonstrated the function of OCT4B in human glioblastomas. Among the isoform of OCT4B, OCT4B-190 ($OCT4B^{19kDa}$) was highly expressed in human glioblastoma stem cells and glioblastoma cells and was mainly detected in the cytoplasm rather than the nucleus. Overexpression of $OCT4B^{19kDa}$ promoted colony formation of glioblastoma cells when grown in soft agar culture conditions. Clinical data analysis revealed that patients with gliomas that expressed OCT4B at high levels had a poorer prognosis than patients with gliomas that expressed OCT4B at low levels. Thus, $OCT4B^{19kDa}$ may play a crucial role in regulating cancer cell survival and adaption in a rigid environment.

The purpose of this study was to investigate the effect of alcohol drinking motivation on the drinking behaviors of female college students. It is necessary to examine the drinking behavior of female college students not only for their academic performance and health status but also for future reproduction concerns. The subjects of this study included 296 college students in their 20s. Research data was analyzed using SPSS 24.0 and AMOS 22 statistical programs. Results of this study found academic and human relationships had the greatest effect on the stress level of female college students. In addition, the perception of drinking was more influential on the drinking problem, and female college students who perceived anxiety through the drinking problem tried to change the behavior of drinking. Also, the perception of drinking by the influence of alcohol was more significant than that of drinking by college students who perceived anxiety through drinking problem. Second, if drinking is beneficial in the internal or external motivation of the individual, it maintains drinking behaviors and changes the behavior of drinking when experiencing the problem of drinking. Through these results, we aim to contribute to the reduction of the negative risk of alcohol by understanding the drinking preference of female college students and examining the drinking culture according to drinking motives.

This study investigated the effects of ozone-produced oxidants (OPO) on the growth, hematology, and histology of olive flounder Paralichthys olivaceus (average weight 500 g), raised in an ozonated semi-recirculating aquaculture system. The system was ozonated to maintained OPO concentrations of 0.004 (Control), 0.014 (OPO15), and 0.025 (OPO25) mg $Cl_2/L$ in culture tanksfor 26 days. The specific growth rate, feed conversion ratio, and survival rate did not significantly differ among the groups (P>0.05), while the daily feeding rate decreased OPO-dose-dependently (P<0.05). OPO appeared to affect the gill, hepatopancreas, and kidney tissues of fish from ozonated tanks. Hematologically, OPO affected some blood indices. The levels of chloride, glucose, glutamic oxaloacetic transaminase, and glutamic pyruvic transaminase were significantly increased in the ozonated groups, while the total cholesterol and cortisol decreased dose-dependently. These results imply that long-term exposure of olive flounder to an OPO concentration ${\geq}0.014mg\;Cl_2/L$ might result in damage to the gill, hepatopancreas, and kidney tissues and cause physiological stress, albeit with no apparent short-term effects on growth or survival.
