Many epidemiological and observational studies show that distorted body image of normal body weight is widespread among Korean young females. This study was performed to evaluate the prevalence of overweight and underweight of young females and, to compare nutrient intakes, body composition, serum indices (lipids, MDA: Malondialdehyde, TAS : Total Antioxidant Status) with different BMI groups. The subjects were 75 university students in Seoul. We divided the subjects into 3 groups according to their BMI by IOTF guideline (UW: underweight group, BMI < 18.5, NW: normal body weight group; 18.5 $\leq$ BMI < 23.0, OW: overweight group; BMI $\geq$ 23.0). Data on dietary intakes, body compositions and serum indices were obtained in 3 groups. Differences on all of the above variables were assessed by body weight groups. Using IOTF guidelines, the prevalence of overweight and underweight in young females were 23%, 61%, 16% respectively. $\beta$-carotene and vitamin A intake of UW were significantly higher than that of NW (p < 0.05). Fiber intakes of NW was significantly higher than that of W (p < 0.05). But intakes of energy and the other nutrients were not significantly different among BMI groups. Calcium and folate intakes were 75%, 61% of KDRIs. Serum TGs were significantly higher in OW than that of NW, UW (p < 0.05), but level of MDA and TAS were not significantly different. The association of overweight and low intake of $\beta$-carotene and vitamin A may be one of many factors predisposing obese females to a high risk of oxidative stress later in life. This requires urgent nutritional intervention programs involving enough intake of fruit and vegetables, with modification of inappropriate dietary habits.

The present study was carried out to investigate differentially expressed chicken muscle proteins using proteomics approach. More than 300 protein spots were investigated for the muscle samples in 2DE gels and the differentially expressed protein spots between pectoralis and peroneus longus muscles from Cornish and White Leghorn breeds were characterized by MALDI-TOF. In pectoralis muscles, PGAM1 protein was detected as differentially expressed between White Leghorn and Cornish breeds. On the other hand, 4 protein spots (SP22, nxf-2, SOD1, TNNI2) were differentially expressed between White Leghorn and Cornish breeds in peroneus longus muscles. These proteins assumed to be related with muscle development, growth, stress, and movements in chicken. In this experimental process, 2D reference map of the chicken muscle proteins was needed and 25 proteins, which were commonly expressed in both pectoralis and peroneus longus muscles in both breeds, were selected and characterized. Upon finishing the exact roles of the differentially expressed proteins, the identified 5 proteins will be used as valuable information for the fundamental mechanisms of muscle biology and underline genetics.

The purpose of this study was to quantitatively examine the physiological and psychological effects of a waterscape facility in an interior landscape space. Data were collected as participants under stress relaxed in either an interior space with greenery(Type G) or an interior space with a waterscape facility(Type W). The participants relaxing in the Type W space showed significantly decreased systolic and diastolic blood pressures, and an impression evaluation by the SD method indicated that their impressions were expressed in more positive terms, such as 'vigor', 'dynamism', 'pleasantness', and 'vitality'; when compared to participants relaxing in the Type G space. A POMS analysis showed waterscape elements influenced participants' psychological mood states by decreasing tension and fatigue, but increasing vitality. Introduction of waterscape facilities into interior landscape spaces could therefore provide stressed individuals with health benefits, including decreased blood pressure and positively changed psychological mood states.

Objectives: This study aimed to investigate North Korean refugees' knowledge of mental illnesses and treatments and analyze the factors affecting this knowledge. Methods: Subjects were selected via a snowball sampling method, and the survey outcomes of 152 North Korean refugee participants were analyzed. The factors affecting knowledge of mental illnesses were analyzed via a regression analysis by constructing a multivariate model with mental illness knowledge score as the dependent variable. Results: The North Korean refugees' mental illness scores ranged from 3 to 24 points, with an average score of 13.0. Regarding the factors that influence mental illness knowledge, the subjects with South Korean spouses and those who had spent more time in South Korea had higher knowledge scores. Furthermore, the subjects who considered the mental health of North Korean refugees to be a serious issue revealed lower knowledge scores than those who did not believe it was a serious issue. The subjects who visit psychiatric clinics showed higher knowledge scores than those who do not. The South Korean subjects who had at least a college education exhibited higher scores than did those without advanced education. The subjects who are satisfied with life in South Korea manifested a higher mental illness knowledge score than those who are not. Conclusions: This study is significant as being the first study to ever measure and evaluate the level of North Korean refugees' knowledge of mental illnesses. In addition, the evaluations of North Korean refugees' mental illness knowledge and influencing factors while residing in South Korea created basic data that formed the foundation of an effort to enhance mental health literacy and provide proper mental health services. The results of this study can be utilized to solve mental health problems that might frequently occur during the unification process of North and South Korea in the future.

The effect of Protox expression site on herbicidal resistance was investigated in wild-type and transgenic rice plants imposed by peroxidizing herbicide oxyfluorfen. The transgenic rice systems involved the plastidal expression of Arabidopsis protoporphyrinogen oxidase (Protox; AP line) and the dual expression of Myxococcus xanthus Protox in chloroplasts and mitochondria (TTS line). The oxyfluorfen-treated TTS4 line showed the lower levels of cellular leakage and malonyldialdehyde and the sustained capacity of 5-aminolevulinic acid synthesis, compared to the oxyfluorfen-treated AP and wild-type lines. During oxyfluorfen action, the TTS4 line had greater herbicide resistance than the AP1 line, indicating that the dual expression of M. xanthus Protox in chloroplasts and mitochondria prevented the accumulation of photodynamic protoporphyrin IX more effectively than the expression of Arabidopsis Protox only in chloroplasts. These results suggest that the ectopic expression of Protox in mitochondria greatly contributes to the herbicidal resistance in rice plants.

This study considers how the fatigue behavior and probabilistic properties of SAE1055 steel are related to its hardness level. SAE1055 steel was heat-treated using induction hardening. Five types of specimens were prepared (A: base material, B: through hardened material with HV390, C: through hardened material with HV510, D: through hardened material with HV700, and E: surface hardened material with HV700). Fatigue tests were performed under a stress ratio of R = -1 using a 4-point rotary bending fatigue tester. The fatigue behaviors were greatly influenced by the hardness, but the fatigue limit did not increase over a hardness of HV510. In addition, the effect of the hardness level on the failure mechanism was evaluated using a scanning electron microscope. The probabilistic properties of the fatigue life were investigated using a probabilistic S-N approach, and the effect of the hardness level on these properties was evaluated using a residue analysis.

Objectives: The nutritional status of cancer patients undergoing chemotherapy is closely related to the compliance of nutrition education. However, as chemotherapy is conducted repeatedly, compliance with nutrition management is lowered, leading to malnutrition. Malnutrition is related directly to the quality of life after surgery in cancer patients. Therefore, this study examined the factors related to compliance with nutrition management during chemotherapy. Methods: In this study, five subjects with colorectal cancer undergoing adjuvant chemotherapy were interviewed in-depth using the Giorgi study method. The contents of the nutrition education visits and in-depth interviews were transcribed in the language of the subject after recording, and the appropriateness of the data was improved by reflecting the subject's actions and facial expressions. Results: After conducting the in-depth interviews for each subject, the experience of the subject's diet and adjuvant chemotherapy was drawn into two domains, six elements, and 26 sub-elements. In the cognitive domain, the patients experienced physical and psychological changes, and the need for nutrition management was recognized by analyzing the dietary causes of the diseases. In the domain of practice, a knowing-doing gap was formed, unlike the patient's will. Factors that inhibited compliance with nutritional management included digestive problems, sensory changes, loss of appetite, and social interaction stress. Conclusions: Dietary management is very important for patients receiving periodic anticancer therapy, and step-by-step training and personal monitoring based on the chemotherapy order is necessary to maintain the patient's will and social and environmental support.

Korean medicated diet (KMD) is not a simple combination of food and Chinese drugs, but a special carefully constructed diet made from Sasang constitutional medicines, food and condiments under the theoretical guidance of diet preparation based on differentiation of symptoms and signs of traditional Sasang medicine (TSM). It combines the functional efficacy of medicine with the delicacy of food, and can be used to prevent and cure diseases, build up one's health and prolong one's life. Korean traditional medicated diet has a long history of development. Although influenced by Chinese medicine, Korean traditional medicine has been developed into a unique system of traditional medicine that has surpassed the continental medical practice, sublimating itself into a native medical practice suitable to Korean lifestyles and physical constitutions. In the 19th century, Lee Jema's Sasang medicine (medicine of four types of energy determining the physical constitution) was introduced. It is an integration of mind and body according to the individual's physical constitution that is categorized allowing a customized method of treatment ideal for each category-making the content of Korean traditional medicated diet even richer. The characteristics of Korean medicated diet are as follows: (1) Laying stress on the wole, selecting medicated diet on the basis of differential diagnosis. (2) Suitable for prevention and treatment, outstanding in effect. (3) Good in taste, convenient for taking. KMD refers to drink and food according to certain prescriptions, by processing and cooking that can be used either for prevention and cure of diseases, or for health care and recovery. The purpose of this review is to introduce TSM and KMD based on Sasang constitutional medicines.
