Currently, both Korea and Japan have cooperated to get a foothold in economic major countries in the Asia through the various economic cooperation and the overcoming of cultural difference in cultural interchanges between two countries. However, in the present age, two countries are on the other road in historical view and conception; the final report over 3 year studies by the two countries' history study partnership commission shows the above views; while Korea has been in base of Japan colonialization's unjustification, Japan has been in base of its facts. The aboves have proved that Japan has not taken an honest self examination and conscience over the history. Accordingly, Japan resistance volunteer memorial is proposed as the educational place to carry down the martyr's holy patriotism in later ages and practice its spirit by learning the resistance volunteer resistance volunteer movement, which focused on resisting the Japan invasion and fighting the independence.

Mitochondrial DNA (mtDNA), a multicopy genome found in mitochondria, is crucial for oxidative phosphorylation. Mutations in mtDNA can lead to severe mitochondrial dysfunction in tissues and organs with high energy demand. MtDNA mutations are closely associated with mitochondrial and age-related disease. To better understand the functional role of mtDNA and work toward developing therapeutics, it is essential to advance technology that is capable of manipulating the mitochondrial genome. This review discusses ongoing efforts in mitochondrial genome editing with mtDNA nucleases and base editors, including the tools, delivery strategies, and applications. Future advances in mitochondrial genome editing to address challenges regarding their efficiency and specificity can achieve the promise of therapeutic genome editing.

As the aging society is globally increasing, the guide for the aged-friendly city is suggested by WHO and many cities are preparing to meet with it. The base of this guide for an age-friendly city is an active aging. This study examined how degree the neighborhood environment is age-friendly from older persons' standpoints. The data were collected through the interview with old persons who aged more than 65 years, 117 persons in an urban area and 110 ones in a rural area. The age-friendly degree of neighborhood environment was examined from two aspects. One is how close 12 neighborhood facilities were from the elderly's houses. Another one is how degree the elderly were considered in 4 areas: pedestrian road, traffic, the amount of housing for the elderly, and space layouts of their houses. Findings were as follows. First, the elderly related neighborhood facilities in urban area were closer located to old persons' houses than in rural area, except the senior center. Second, in case of the age-friendly degree of their neighborhood environments, the space layout of house was the highest, and then traffic, pedestrian road, and the amount of housing for the elderly, in order. The consideration degree of wheelchair users was the lowest. Third, the age-friendly degree of pedestrian road, traffic, and room layout of house in rural area were higher than in urban area. However, the amount of housing for the elderly in urban area was higher than in rural area.

The research is focused on relationship between body fat percentage and physical characteristics of women in age group between 20s and 30s who experience great deal of physical change such as marriage, pregnancy, delivery, breast-feeding, and etc. The research used physical measurement of two hundreds women: 50 women in their early twenties, 50 women in their late twenties, 50 women in their early thirties, and 50 women in their late thirties. The research provides base data for women clothing industry by observing relationship between physical figure and body fat percentage rate based on obesity study on body fat percentage, physical BMI, R$\ddot{o}$hrer Index, and Vervaeck Index. Followings are conclusion of the research. The older the ages, the shorter the height and the heavier the weight. Recognizable differences in circumference, thickness, and width rather than in length are found. Also recognizable increases in average body fat percentage and average physical characteristics by age have found. By observing body fat percentage and physical measurements, it was revealed that weight has more effect on body fat percentage than height in all ages. Circumference, width, and thickness have more impact than length measurements among physical measurements. Main body or upper body has more impact than legs and arms or lower body. Body fat percentage increase rapidly by ages. 2.0% of age 20~24, 20.0% of age 25~29, 28.0% of age 30~34, and 54.0% of age 35~39 were sorted as obesity.

The Janggun magnetite deposits occur as the lens-shaped magnesian skarn, magnetite and base-metal sulfide orebodies developed in the Cambrian Janggun Limestone Formation. The K-Ar age of alteration sericite indicates that the mineralization took place during late Cretaceous age (107 to 70 Ma). The ore deposition is divided into two stages as a early skarn and late hydrothermal stage. Mineralogy of skara stage (107 Ma) consists of iron oxide, base-metal sulfides, Mg-Fe carbonates and some Mg- and Ca-skarn minerals, and those of the hydrothermal stage (70 Ma) is deposited base-metal sulfides, some Sb- and Sn-sulfosalts, and native bismuth. Based on mineral assemblages, chemical compositions and thermodynamic considerations, the formation temperature, $-logfs_2$, $-logfo_2$ and pH of ore fluids progressively decreased and/or increased with time from skarn stage (433 to $345^{\circ}C$, 8.8 to 9.9 atm, 29.4 to 31.6 atm, and 6.1 to 7.2) to hydrothermal stage (245 to $315^{\circ}C$, 11.2 to 12.3 atm, 33.6 to 35.4 atm, and 7.3 to 7.8). The ${\delta}^{34}S$ values of sulfides have a wide range between 3.2 to 11.6‰. The calculated ${\delta}^{34}S_{H_2S}$ values of ore fluids are relatively homo-geneous as 2.9 to 5.4‰ (skam stage) and 8.7 to 13.5‰ (hydrothermal stage), which are a deep-seated igneous source of sulfur indicates progressive increasing due to the mixing of oxidized sedimentary sulfur with increasing paragenetic time. The ${\delta}^{13}C$ values of carbonates in ores range from -4.6 to -2.5‰. Oxygen and hydrogen isotope data revealed that the ${\delta}^{38}O_{H_2O}$ and ${\delta}D$ values of ore fluids decreased gradually with time from 14.7 to 1.8‰ and -85 to -73‰ (skarn stage), and from 11.1 to -0.2‰ and -87 to -80‰ (hydrothermal stage), respectively. This indicates that magmatic water was dominant during the early skarn mineralization but was progressively replaced by meteoric water during the later hydrothermal replacement.

Purpose: The arterial base deficit and the serum lactate level are widely recognized indicators of injury severity, adequacy of resuscitation and outcome. The purpose of this study is to evaluate the usefulness of the arterial base deficit as an injury-severity indicator in multiple-trauma patients with head injuries. Methods: Data were retrospectively collected from trauma patients over 18 years of age who had been admitted at the emergency center between October 2005 and July 2006. The patients were divided into head-injury and non-head-injury groups. These patients were then sub-divided into minor ($$ISS{\leq_-}15$$)-injury and major ($$ISS{\geq_-}16$$)-injury groups according to their injury severity scores (ISS). We analyzed the differences in the base deficits and the serum lactate levels between the major- and the minor-injury sub-groups in both the head-injury and the non-head-injury groups. Results: In the non-head-injury group, we found statistically significant differences in the arterial base deficit between the major-injury and the minor-injury sub-groups($-6.86{\pm}2.40mmol/L$ vs. $-1.37{\pm}0.73mmol/L$, p=0.010). In the head-injury group, no significant differences were noted between the two sub-groups($-2.50{\pm}1.28mmol/L$ vs. $-1.51{\pm}0.74mmol/L$, p=0.897). Moreover, the differences in arterial base deficit between the major-injury and the minor-injury sub-groups were not significant both for either single-head-trauma or multiple-head-trauma patients (p=0.643 vs. p=0.832). Conclusion: We conclude that neither the arterial base deficit nor the serum lactate level can be used to predict injury severity in multiple-trauma patients with head injuries.

Objective: The objective of the study is to analyze adult men's somatotype characteristics, age range from 20s to 50s comparing the direct anthropometric measurement values and to provide the basis information for developing clothing patterns. Background: The comparative study among the age groups is very fundamental to understand the body characteristics of each subjects group. Therefore, comparison of body measurements in age groups was applied in this study. Method: The anthropometric data from the $5^{th}$ Anthropometry of Size Korea(2004) and $6^{th}$ Anthropometry of Size Korea(2010) were applied for the data analysis. Results: As a result, the chest depth/chest width index(the value of chest depth divided by chest width) was increased and the waist depth/waist width index was decreased in all age groups. In addition, the hip depth/hip width index was decreased in age of 20's and 50's. This means that the chest width and hip width were decreased and the waist width were increased. From the data of the 5th Size Korea, the obese men(BMI: 25~30) in the 50s showed the highest percentage of 47.1%, and 44.8% of obese men(BMI: 25~30) in the 40s recorded the highest rate base on the data of the 6th Size Korea. Conclusion: It is concluded that the some differences were showed between the 5th anthropometric data and the 6th data. In particular, obesity tendencies of men in their 20's and 30's were observed significantly compared to other age groups. Application: These findings from the study can be utilized men's wear design and construction that reflect body characteristics.

The purpose of this study was to analyze the dietary habits and food intake by age, based on the nutrition counseling data of medical health examination. The subjects were 5,511 adults(3,139 males and 2,372 females) who took comprehensive medical test in Gyeonggi area, and they were evaluated from January 1, 2007 to December 31, 2007. Survey samples were divided by age groups : 30>, 30~39, 40~49, 50~59, 60~69, 70{$\leq}$ years. The subjects were composed of 57% male and 43% female. The results showed that the dietary habits of ${\geq}$50 group were relatively good. On the other hand, in 30> yrs group had more dietary habit problems, they had irregular meals and the ratio of skipping breakfast was high. And they frequently had meals out. regularity of meals, eating breakfast was higher in ${\geq}$70 yrs groups than in other groups(p<0.001). frequency of overeating was higher in 30>, 30~39${\geq}$yrs groups than in other groups(p<0.001) and speed of eating meal were fast in 50~59 yrs groups than in other groups(p<0.01). For foods with high cholesterol and fat, it was shown that the older the subject, the fewer the frequency of consumption(p<0.001). For kimchi and salty foods, food intake showed a negative relationship with age(p<0.001), whereas for fresh vegetables and high-calcium fish, it showed a positive relationship(p<0.001). All in all, it was shown that as the people get older, their dietary habits tend to get more appropriate. In conclusion nutrition education based on their dietary habit by age should be taught, so that people have a healthy dietary habit and food intake for the rest of their life.

This study was conducted in order to obtain the information of the histological changes in each of six segments of the epididymal ducts in Korean native goats. Thirty-two Korean native male goats were examined, dividing into seven groups, at 4 weeks intervals from 8 to 32 weeks of age. The results obtained were as follows. 1. The epididymal ducts showed histologically an abrupt growth at the age of 16 weeks being followed by almost full maturation at the age of 24 weeks. Diameter of the cauda was steadily larger than that of the caput and corpus of the epididymal ducts. 2. Spermatozoa in the lumen of epididymal ducts were first observable at the age of 16 weeks, thereafter showing sparse in the lumen of caput, whereas most dense in the lumen of cauda in the density of spermatozoa. 3. Ducts in the caput and corpus were lined by ciliated columnar epithelium until the age of 12 weeks, and later by pseudostratified ciliated columnar epithelium which was composed of ciliated columnar cells, clear cells and basal cells. Ducts of cauda epididymis were lined by simple ciliated columnar epithelia until 12 weeks of age and later by simple or pseudostratified ciliated columnar epithelium, and two types of ducts (small ducts with high epithelium and large ducts with lower epithelium) were noted. Nucleus of the epithelial cells in the caput were located in the base of cells but in the corpus and cauda, those were located in the mid part of cells. cilia were most developed in the epithelia of the corpus.
