The aim of this study is to analyze tthe pattern of compacted area and the distribution characteristics in one-person household. Through ArcGis, we collect the basic data and classify the compact area in accordance with the pattern employing Ward method out of cluster analysis. The main results are found as follows; First, the station sphere type is located around Seomyun and Nampo-dong, which are the main CBD( Central Business District) This type must be essentially considered in residential plan for one-person household location. Second, the district oriented type is located around the subway and it has relatively better residential facilities and environments. Third, it is found that the younger worker including students resided in one room and villa in the type around university. Forth, the foreign workers and domestic workers in small and medium factory resided in the factory centered type which is far from the station sphere. Lastly, it is dormitory type which is isolated from the CBD, and insteadly amenable and well natural environment area, but students and workers in this area where there are lacking life-related facilities and aside from accessibilities feel uncomfortable.

The metamorphic rocks of Yongin-Anseong area in Gyeonggi massif are composed of high-grade gneisses and schists which are considered as Precambrian basement, and Jurassic granite which intruded the metamorphic rocks. In this paper, we discuss the geochemical characteristics of metamorphic rocks and granites in this area based on REE and Nd isotope geochemistry. And we also discuss the petrogenetic relationship between metamorphic rocks and granites in this area. Most of Nd model ages (T$\_$DM/$\^$Nd/) from the metamorphic rocks range ca. 2.6Ga～2.9Ga which are correspond to the main crustal formation stage in Gyeonggi massif by Lee et. al. (2003). And Nd model ages show that the source material of quartzofeldspathic gneiss is slightly older than that of biotite banded gneiss. In chondrite-normalized rare earth element pattern, the range of (La/Yb)$\_$N/ value from biotite banded gneiss is 37～136, which shows sharp gradient and suggests that biotite banded gneiss was originated from a strongly fractionated source material. However, that of amphibolite is 4.65～6.64, which shows nearly flattened pattern. Particularly, the chondrite normalized REE patterns from the high-grade metamorphic rocks show the REE geochemisoy of original source material before metamorphism. In addition, the values of (La/Yb)$\_$N/ and Nd model ages of granite are 32～40 and 1.69Ga～2.08Ga, respectively, which suggest that the source material of granite is different from that of Precambrian basement such as biotite banded gneiss and quartzofeldspthic gneiss in the area.

Korea Central Cancer Registry reported in 2011 that the prevalence rate of thyroid cancer was about 19.6% (the highest) in both men and women. The ratio of thyroid cancer, among cancers that women suffer from, was about 31.1%, the highest among female cancers and about five times more than men. Regarding the incidence of thyroid cancer by age group, the crude rate was highest in women and men aged 15~34. From these figures it can be inferred that there is a greater relationship between thyroid cancer and hormones compared with other cancers. Therefore, young women aged 20~25, even if they are in full health, should undergo a medical examination. This study is aimed at examining changes in thyroid gland detected through self evaluation tests and the analysis of ultrasound screening images in persons aged 20~25. According to the study, 213 persons (about 46.6%) out of 457 people who took part in the study had abnormal echo patterns. With regard to women's abnormal patterns, about 73.4% of them were found to have calcified cystic, 11.8% diffuse-type low-echo and 7.3% cystic echo. With regard to male participants, about 61.1% were found to have calcified cystic, followed by 19.4% with the size of the isthmus increased and 13.9% with diffuse-type low-echo. According to the outcomes of an analysis regarding self-testing for hyperthyroidism, the average points of participants who were found to have abnormal echo patterns in ultrasound tests were 6.85 and the figure was 5.88 in persons with normal patterns. The figure was about 15% higher in abnormal respondents.

The purpose of this study was to investigate the effect of different ramp inclination on the maximum plantar foot pressure and pathway of the center of pressure. Fifteen healthy adults who had no musculoskeletal disorders were participated with this study and descended the ramp with different inclination(level, $-5^{\circ}$, $-10^{\circ}$, $-15^{\circ}$). Plantar foot pressures were recorded by the Matscan system(Tekscan, Boston, USA) during level and descending ramp with barefoot. Plantar foot surface was defined as seven regions for pressure measurement; two toe regions, three forefoot regions, one midfoot region, one heel region. Repeated ANOVA was used to compare each region data of foot according to different ramp inclination. As descending ramp inclination became increased, the pressure of hallux region was significantly increased at $-15^{\circ}$ inclination and the pressure of 2-3 metatasal head region were significantly decreased at $-5^{\circ}$, $-10^{\circ}$, $-15^{\circ}$ inclination. The pathway of COP had a tendency to be shifted inside in forefoot and prolonged to great toe as the descending ramp inclination increased. The results indicated that plantar foot pressure could be changed at hallux and forefoot regions with $-5^{\circ}$ ramp inclination and these findings demonstrated that ramp inclination could affect the structure and function of foot.

The purpose of this study is to check effects on the awareness of parents supporting in their self retirement preparation of the baby boomer generations who have faced relatively bad situation in this era considering the reality of great changes brought in the parents supporting spirit which was regarded as family and individual responsibility due to the rapid industrialization and urbanization. In the result of this study, some points such as religious, living status and monthly average earning show meaningful result and also all of the colligation in the retirement preparation standard concerning economic living life, health life, leisure time, family life, dwelling life and leisure life shows most significance probability of .001(*p<0.05) and retirement preparation standard relative to economic life indicates significance probability of .005(*p<0.05). Eventually this result shows that the higher people have retirement standard, the higher parents supporting sprit they have. So I would like to suggest some policy advices on the basis of this study. First stable supporting policy on their dwelling life should be assisted by differential methods, secondly social programs aid for leisure life through social activities like volunteer work are required, further more national based policy supports for youngsters are considered in order to reduce economic daily life on their economic activities.

Summary. Most of American pop music, which are dominating the hegemony of the global pop music market, have been derived from the culture of African Americans, most of whom were slaves of European immigrants. The music of black slaves must be the one of the greatest undisputed achievements that have most influenced the American history. Indeed, All of the mainstream pop music works around the world, including those in America, are the descendants of the black music with the gene of the black people. We can say, therefore, the music born through the Afro-American culture has become the music that every person around the world enjoys in the present. Accordingly, K-Pop music culture, centered in idol group, is also based on the black music. This fact suggests that the K-Pop culture can be spread into people in different customs or traditions with little resistance. The success factor of Motown, at the very center of the black music, which integrated the whole global music, is not only their incredibly outstanding music works, but also the self-consciousness the musicians have that they are strongly reluctant to settle down to present reality. This shall lead to the necessity of self-reflection for the Korean music market, which are obsessed with present popularity and only taking advantage of teenager market, and for those engaged in music business in Korea, who are lack of the artistic value and the consciousness as artist.

Objective: Diurnal preference is an attribute reflecting whether people are alert and preferring to be active either early or late in the day. It also referred to as chronotype or morningness-eveningness trait. The PER3 genes have been known to influence diurnal preference. In this study, we have investigated the associations between the PER3 gene polymorphisms and diurnal preference in a healthy young population, controlling for the social and environmental confounding factors. Methods: The participants in this experiment included 299 unrelated medical college students (M=191, F=108), with a mean age of 22.9 years. Diurnal preference was measured by a single administration of the 13-item Composite Scale for Morningness (CSM). Genotyping of the PER3 VNTR (rs57875989) was performed using polymerase chain reaction. A two-tailed alpha of 0.05 was chosen. Results: The mean${\pm}$SD score on the CSM scale for all subjects was 31.90${\pm}$6.39. There was no significant difference in total CSM score between gender groups, although females showed a trend towards higher morningness score. Although PER3 5R/5R showed the tendency towards high CSM scores, there were no significant differences on CSM scores among genotypes and allele status of PER3 VNTR (rs57875989). Conclusions: We could not confirm that the PER3 VNTR is associated with diurnal preference in a Korean healthy young population. The future studies need to investigate the association between diurnal preference and other polymorphisms of PER3 gene in larger sample of Korean young healthy population.

The aim of this study was to investigate the eating behavior and nutritional status of subjects according to their purpose of exercise. A total of 214 subjects, 20 to 30 years of age, who visited fitness centers in Seoul were enrolled. Anthropometrics, exercise habits, nutritional knowledge, and eating behaviors were analyzed using a questionnaire. Nutritional status was assessed by serial 24 h recalls. The subjects were divided into two groups based on their purpose of exercise: increasing muscle (Muscle growth, n=107) or losing body weight (Weight loss, n=107). The Muscle growth group contained a higher percentage of men, whereas the Weight loss group contained a higher percentage of women. The Muscle growth group showed significantly higher scores of nutritional knowledge and eating behaviors compared to the Weight loss group. The Muscle growth group also had a significantly higher intake of energy and protein compared to the Weight loss group. In fact, the intake of energy in the Weight loss group was lower than the estimated energy requirement (EER) for both men and women subjects. The intake of protein in the Muscle growth group was twice as much as the recommended nutrient intake (RNI). The intake of calcium in both groups was less than the RNI. In conclusion, those who exercised with the aim of increasing muscle took excess dietary protein and those who exercised with the aim of weight loss had a lower energy intake than the EER.

Malignant hyperthermia is a hypermetabolic, fatal syndrome triggered by anesthetic drugs that occurs frequently in genetically susceptible persons. It is characterized by tachycardia, rapidly increasing temperature, skeletal muscle rigidity, respiratory and metabolic acidosis, cyanosis etc. It has been noted that the majority of cases of malignant hyperthermia are fatal unless early diagnosis and treatment are performed. Thus, the accurate prediction of preanesthetic susceptibility and early diagnosis of malignant hyperthermia is necessary to appropriate treatment. Dantrolene sodium has been shown to be effective in the prevention and treatment of malignant hyperthermia. We experienced a case of malignant hyperthermia, which is presented of a 32-year-old healthy male patient in whom a orthognatic surgery was performed under $O_2-N_2O$-enfl-rane anesthesia with induction by pentobarbital and succinylcholine. We discuss this case with reviewing the history, incidence, etiology, pathophysiology, clinical signs & biochemical changes, prevention & treatment.
