Objectives This study was conducted to investigate the possibility of neurological soft signs as an endophenotype for schizophrenia by examining neurological soft signs in patients, their unaffected siblings and normal comparison subjects. Methods The study sample consisted of 32 patients, 25 of their unaffected siblings and 30 normal comparison subjects. Neurological soft signs were evaluated using the Cambridge Neurological Inventory Part 2. soft sign assessment. Results The patients were significantly more impaired than normal comparison subjects (p = 0.047) on primitive reflex. The patients were significantly more impaired than siblings (p = 0.004) and normal comparison subjects (p = 0.021) on motor coordination. The siblings performed better on sensory integration than the patients (p = 0.020) and normal comparison subjects (p = 0.036). Conclusions This study suggests that neurological soft signs might be a potential biomarker for schizophrenia, but might not be an endophenotype for schizophrenia.

There is a growing need for technology transactions between the technology providers, who develop technologies, and the technology consumers, who purchase and commercialize technologies, to be smooth, when technologies, as intangible assets, are traded as items that can be purchased and sold. In response to these challenges, this study examines new approaches to assessing the fair market value of technologies. Because corporations are the main force behind technology development and commercialization in the existing business environment, applying one valuation method to technology assets is viable; however, as the subjects of technology development and technology commercialization are separate, the need for price negotiations between the subjects of technology transaction has grown. Moreover, as the investigations into and the application of transaction prices have been performed separately by technology providers, technology consumers, and technology assessment financial institutions, the research on technology valuation methods has shown that there are differences in perceived transaction prices between the subjects involved. This research presents a new method, appropriate to technology transactions; unlike existing methods, it grants option values to the technology provider and newly defined key variables to the technology consumer.

The purpose of this study was to identify the effects of continuous muscle strengthening applied to the antagonist of the sternocleidomatoid, upper trapezius, and pectoralis major, which are the shortened muscles of forward head posture(FHP) subjects, and Evjenth-Hamberg stretching(EHS) applied to the shortened muscles on changes in pressure pain threshold(PPT). Twenty subjects were divided into the continuous antagonist strengthening(CAS) group(n=10) and the EHS group(n=10), and each group performed its respective exercise three times a week for a six week period. The results were as follows: The comparison of changes in PPT within each group before and after the treatment showed a statistically significant difference(p<.05) according to the treatment period and a statistically significant difference according to the treatment period and method(p<.05). While the comparison of the tests of between subjects effects between the groups did not show a statistically significant difference, the CAS group exhibited better effects. The above results suggest that the combined application of CAS and EHS generates better effects on changes in PPT than the single application of EHS. Given that stretching and muscle strengthening exercises even for the short research period of six weeks could change the PPT, continuous exercises and a correct postural habit for a longer period of time are likely to help prevent chronic pain and correct FHP.

The purpose of this study was to examine and understand body image, appearance behaviors, and eating disturbances among females in the Diet Center. Subjects for this research were 40 females enrolled at the Diet Center in Seoul. They were interviewed for this study using an interview schedule at September in 2004. As a result, most of the subjects (87%) were dissatisfied with their bodies, especially their lower body such as hip, thighs, legs, stomach. Subjects tended to use dieting and fasting (46.3%) as the most common appearance management behaviors in relation to the body parts. Make-up (32.9%) was also used as routine appearance behaviors, while 37.5% of subjects have had cosmetic surgery on eyes, nose and liposuction. Sixty percent of subjects had participated in Diet center programs more than twice. This may mean that society pressures women to have a slim body, which then will result in more self-confidence. Subjects tend to engage in unhealthy eating behaviors, such as 'fasting', 'inducing vomit', 'using diet pills or laxatives', and 'after chewing, spit out'. Based on these results, socio-cultural body image regarding ideal beauty would be discussed.

Spirulina is a microscopic and filamentous cyanobacterium that contains essential amino acids, essential fatty acids, vitamins, minerals and anti-oxidative components. The purpose of this study was to examine effects of spirulina intervention in Korean patients with type 2 diabetes. The subjects were 37 type 2 diabetic patients who visited a diabetic clinic in Seoul and randomly assigned into spirulina (8 g/day) or control group. During the intervention period of 12 weeks, subjects were asked to keep usual diet and prohibited to take any functional foods or dietary supplements. Spirulina supplementation for 12 weeks did not affect anthropometric parameters, however, lowered plasma triglycerides level significantly (p<0.05). Spirulina supplementation also resulted in a significant reduction in plasma malondialdehyde level (p<0.05) and an increase in plasma adiponectin level (p<0.1). The lipid lowering effect of spirulina supplementation was different according to serum lipid levels of the subjects before entering the intervention. The subjects with higher initial triglyceride level showed higher reduction in plasma triglyceride and blood pressure. The subjects with higher initial total cholesterol and LDL-cholesterol level showed higher reduction in plasma concentrations of total cholesterol, LDL-cholesterol, IL-6, and blood pressure. It seems that spirulina supplementation is more effective in subjects with dyslipidemia. This study provides the evidence for beneficial effects of spirulina supplementation on blood lipid profiles, inflammatory variables, and antioxidant capacity in Korean patients with type 2 diabetes. The results suggest that spirulina is a promising agent as a functional food for diabetes management.

BACKGROUND/OBJECTIVES: International students face dissimilar food environments, which could lead to changes in dietary behaviors and anthropometric characteristics between before and after migration. We sought to examine the risk factors, including dietary behaviors, acculturation, and demographic characteristics, related to overweight subjects residing in South Korea. SUBJECTS/METHODS: We conducted a cross-sectional study, collecting data from 142 Chinese international students (63 males, 79 females) in 2013. RESULTS: The mean age of the subjects was 25.4 years, and almost half of them immigrated to South Korea to earn a master's degree or doctoral degree (n = 70, 49.3%). Chinese international students showed an increase in skipping meals and eating speed, but a decrease in the frequency of fruit and vegetable consumption in South Korea compared to when they lived in China. We found a statistically significant increase in weight (69.4 ${\rightarrow}$ 73.9 kg) and BMI (22.4 ${\rightarrow}$ $23.8kg/m^2$) for male subjects (P < 0.001) but no change for female subjects. We also found that overweight subjects were more likely to be highly acculturated and male compared with normal-weight subjects. CONCLUSION: Among Chinese international students living in South Korea, male and more highly acculturated subjects are more vulnerable to weight gain. This study provides useful information to design tailored nutrition intervention programs for Chinese international students.

The purpose of this study was to describe the way of life (such as smoking habits, alcohol consumption, exercise, duration of sleep, eating habits etc.), physical. psychological and overall health complaints and to identify the relationship between the way of life and health complaints of the nursing students. Data was collected with the self-administered OMI( Okayama Medical Index Health Questionnaire, devised Cornell Medical Index) from 766 nursing students and was analyzed. For data analysis, descriptive statistics and an ANOVA with an SPSS/PC+ program were used. The results were as follows: 1. The mean age of subjects was 21.0557(2.7618) years old in their 1st, 2nd, 3rd and 4th year-classes of nursing departments and college students in 4 regions of Korea. 62.1% of subjects were of the proper body weight, 2.0% were overweight, and 28.3% were underweight. Most subjects did not have a past history of disease, but 1.8% of subjects had experienced a blood transfusion. 2. 28.3% of the subjects had averaged 7 hours of sleep, 98.5% were nonsmokers, 91.2% were nondrinkers, 74.7% of subjects had milk intake sometimes, 53.7% of the subjects had an average salt intake, 49.6% of the subjects usually had a green vegetable intake, 45.4% of the subjects sometimes had fatty food intake, 64.8% of the subjects had good taste, 29.5% of the subjects enjoyed physical exercise. 3. The highest percentages of 'yes' among physical. psychological and overall health complaints were observed in the question 'Do you have gastric pain?'(60.2%), 'Are you confused of disorderly?' (37.2%), 'Physical body was burdensome and fatigued.'(57.3%). 4. The total O.M.I. score ranged from 1 to 89 with an average of 22.91(SD=12.10). A statistically significant difference was observed for the physical. psychological complaints for alcohol consumption. and for the psychological complaints for salt and fatty food intake. These conclusions should provide grounds for future studies of strategies for health promoting lifestyle for nursing students and their health concerns. Further research is required to investigate the life environmental and psychological factors affecting the way of life for nursing students and their health status, to analyze the health behavior of nursing students related with their culture and consciousness. Also epidemiologic research methodology, such as prospective cohort study should be considered to explore the performing process of nursing student's health behavior related with the occurrence of diseases.
