Heritability and genetic correlation for growth traits in Duroc pig breed were estimated using Bayesian method via Gibbs sampling. The data set consisted of 3,526 performance records at National Institute of Animal Science. For estimating those parameters using Gibbs sampling, 5,000 cycles of ‘burn-in’ period were discarded among a total of 55,000 samples. Out of the remaining 50,000 samples, 5,000 estimates by each parameter were retained and used for analyses to avoid any correlation among adjacent samples. The growth traits considered in this study were average daily gain at 30kg(ADG1), average daily gain at 90kg(ADG2), backfat thickness(BF), days to 90kg(D90) and feed conversion ratio(FC). The estimated heritabilities and their standard deviation using Gibbs sampler were 0.43±0.04, 0.49±0.038, 0.31±0.040, 0.48±0.039 and 0.62±0.086, respectively. Genetic correlations were －0.02, －0.13, －0.55 and －0.15 between ADG1 with ADG2, BF, D90 and FC, respectively, 0.16, －0.73, －0.32 between ADG2 with BF, D90 and FC respectively, 0.01, －0.08 between BF with D90, FC, respectively, and 0.23 between D90 with FC.

The purpose of this study is to summarize tropical cyclone activity in 2007. 24 tropical cyclones of tropical storm (TS) intensity or higher formed in the western North Pacific and the South China Sea in 2007. The total number is less than the thirty-year (1971~2000) average frequency of 26.7. Out of twenty four tropical cyclones, 14 TCs reached typhoon (TY) intensity, while the rest 10 only reached severe tropical storm (STS) and tropical storm (TS) intensity - four STS and six TS storms. The tropical cyclone season in 2007 began in April with the formation of KONG-REY (0701). From April to May, two TCs formed in the western North Pacific in response to enhanced convective activity there. From June to July, convective activity turned inactive over the sea around the Philippines and in the South China Sea, and the subtropical high was weak over the south of Japan. MAN-YI (0704) and USAGI (0705) moved northwestward and hit Japan, bringing serious damage to the country. After August, convective activity became enhanced over the sea east of the Philippines, and the subtropical high turned strong over the sea south of Japan. Many TCs, which formed over the sea east of the Philippines and in the South China Sea, moved westward and hit China and Vietnam. PABUK (0706), WUTIP (0707), SEPAT (0708), WIPHA (0712), LEKIMA (0714) and KROSA (0715) brought serious damage to some countries including China, the Philippines and Vietnam. On the other hand, FITOW (0709) and NARI (0711) moved northward, bringing serious damage to Japan and Korea. After HAIYAN (0716), all four TCs except FAXAI (0720) formed over the sea east of $140^{\circ}E$. Three typhoons among them affected Republic of Korea, MAN-YI (0704), USAGI (0705) and NARI (0711). Particularly, NARI (0711) moved northward and made landfall at Goheng Peninsula ($34.5^{\circ}N$, $127.4^{\circ}E$) in 1815 KST 16 September. Due to $11^{th}$ typhoon NARI, strong wind and record-breaking rainfall amount was observed in Jeju Island. It was reported that the daily precipitation was 420.0 mm at Jeju city, Jeju Island on 16 September the highest daily rainfall since Jeju began keeping records in 1927. This typhoon hit the southern part of the Korean peninsula and Jeju Island. 18 people lost their lives, 14,170 people were evacuated and US$ 1.6 billion property damage was occurred.

This study was aimed at examining the pattern of dietary fat intake of 120 university female students living in Kongju city in order to provide baseic data for establishing the dietary grideline of desirable fat intake. The subjects were divided into three groups according to living arrangenment ; family home(FH), or dormitory(DM), or self-boarding house(SB). Fat consumption of subjects was surveyed by two-day food records, and profiles of fatty acid and cholesterol taken were calculated based upon the data reported their contents of foods. The result was that mean daily fat intake was 42$\pm$2g for FH, 48$\pm$4g for DM and 41$\pm$3g for SB. The calorie intake by fat was 20.8, 21.5, and 20.4% respectively. The ratio of P/M/S was 1.3/1.7/1 for FH, 1.3/1.6/1 for DM and 1, .5/1.5/1 for SB. And the ratio of n-6/n-3 fatty acid was 5.2/1 for FH, 8.3/1 for DM and 7.2/1 for SB. Daily cholesterol intake was 208$\pm$20mg for FH, 223$\pm$29mg for DM and 251$\pm$27mg for SB. In addition, intake of n-3 fatty acid was 1.2$\pm$0.2g for FH, 0.9$\pm$0.1g for DM and 1.2$\pm$0.2g for DB. Considering the food source of fatty acids, saturated fatty acid and monounsaturated fatty acid were taken primarily from animal foods, especially milk and milk products, and n-6 polyunsaturated fatty acid was taken from vegetable oils and fats. As a major source of n-3 fatty acid, linolenic acid was obtained through vegetable oils and fats, and eicosapentaenoic acid and docosahexaenoic acid were provided by fishes and their products. There patterns of fatty acid intakes did not differ according to living arrangement. The above results showed that intakes of fat and cholesterol, and ratios of P/M/S and n-6/n-3 fatty acid were overall desirable in all groups. However, intake of n-3 fatty acid was low in all groups. Therefore, consumption of perilla oil, legumes and fishes as a source of n-3 fatty acid should be increased by substituting other food source which provide fats and oils because calorie intake by fat was enough in these subject.

The primary purpose of this research paper is to study the nutrition intake status of high school students and their physical growth and development. Further, it made an attempt to find and define nutritional problems and assist in their growth and development through proper nutritional management. One hundred students in both sexes, first year grade in senior high school were provided with questionnaires. For six days the respondents filled out the questionnaires. They were asked to keep record of what they ate each meal. Their nutritional intake were analyzed in accordance with what they ate. Findings, conducted on percentage, CR test, t test, and F test, were as follows: 1. For the living circumstance a) Average numbers of brother and sister in sampled family were four. b) Seventy to eighty percent of the students were brought up by mother's milk at their infants and approximately 40% of students were weaned at the age of 7 to 18 months. c) Fifty percent of the respondents revealed irregulity in their meal time. d) Monthly average expenditure for daily food reached $20{\sim}40%$ out of total income. e) The most favorite foods reflect as follows: The most favorite main dish is boiled rice and side dish beaf. Fruits. juice, milk, ice cream are more popular snack among whole students. 2. Nutrition survey a) Calory sad nutrients were found to be below the recommended level, especially in calcium, vitamins A, $B_2$ and C. b) The total calory intake were composed of 73% from carbohydrate, 14% from protein and 13% from fat in the case of boys. The girls were 65%, 14%, 21% respectively. c) Both boys and girls in their animal protein intake averaged about 33% out of total protein intake. d) Meat consumption of the majority respondents were proportionate in $10{\sim}20%$ in their total food consumption. 3. The result of statistical analysis were as follows: a) Statistical significant differences in the relationship between the calory intake and physical growth index were observed at the level of p<0.05. b) Statistical significant differences in the relationship between the protein intake and physical growth index were observed at the level of p<0.05. c) Statistical significant differences in the relationship between meal time and physical growth index were observed at the level of 0.02<0.05. d) No statistical significant differences in the relationship among calory, protein intake and school records as well as intelligence were found. The experiment indicated that there is a direct relationship between nutrition and the physical growth and development, whereas There seems to be an indirect relationship between nutrition and intelligence.

This study investigated the relationship between total sugar intake and obesity indices in 362 female university students. This study was conducted using an anthropometric checkup and 3-day dietary records. Subjects were categorized according to the total sugar intake as < 33.3 g (group I, n = 90), 33.3-56.1 g (group II, n = 91), 56.1-83.8 g (group III, n = 91), ${\geq}$ 83.8 g (group IV, n = 90). No significant differences in age, weight, height, body mass index (BMI), or the percentage of body fat were observed among the four groups. Based on BMI, 20.2% were overweight, and the percentage of body fat was > 30% in 67.1% of all students sampled. Energy intake in each groups was 1,164.7 kcal, 1,488.6 kcal, 1,590.0 kcal, and 1795.8 kcal, respectively (p < 0.001). Total sugar intake in the groups was 20.5 g, 44.6 g, 68.3 g, and 111.8 g, respectively (p < 0.001). Carbonated beverages were identified as the most significant food source for total sugar intake in female university students. The next major foods were ice cream, milk, coffee, fruit, sugar, cookies, bread, chocolate, corn syrup, rice, onion, maple syrup, pickle, and sweet potato. As intake of total sugar increased, intake of energy also increased significantly. Mean daily intakes of fat and calcium/1,000 kcal were significantly higher in group IV than those in the other groups. Mean daily intakes of vitamin C and vitamin E/1,000 kcal were significantly higher in group III than those in the other groups. The percentage of subjects who consumed nutrients below the estimated average requirement was less in the higher total sugar intake group than that in the lower intake group. The obesity indices (weight, BMI, % body fat) were not associated with total sugar intake in the subjects. We conclude that total sugar intake does not seem to influence obesity indices in female university students.

Background: Utilizing geriatric screening tools for the identification of vulnerable older patients with cancer is important. The aim of this study is to evaluate the hospitalization risk of elderly hematologic cancer patients based on geriatric assessment and laboratory parameters. Materials and Methods: In this cross sectional study 61 patients with hematologic malignancies, age 65 years and older, were assessed at a hematology outpatient clinic. Standard geriatric screening tests; activities of daily living (ADL), instrumental activities of daily living (IADL), Mini Nutritional Assessment (MNA), Mini Mental State Examination (MMSE), timed up and go test (TUG), geriatrics depression scale (GDS) were administered. Demographic and medical data were obtained from patient medical records. The number of hospitalizations in the following six months was then recorded to allow analysis of associations with geriatric assessment tools and laboratory parameters. Results: The median age of the patients, 37 being males, was 66 years. Positive TUG test and declined ADL was found as significant risk factors for hospitalization (p=0.028 and p=0.015 respectively). Correlations of hospitalization with thrombocytopenia, vitamin B12 and folic acid deficiency were statistically significant (p=0.004, p=0.011 and p=0.05 respectively). Conclusions: In this study, geriatric conditions which are usually unrecognized in a regular oncology office visit were identified. Our study indicates TUG and ADL might be use as predictive tests for hospitalization in elderly oncology populations. Also thrombocytopenia, and vitamin B12 and folic acid deficiencies are among the risk factors for hospitalization. The importance of vitamin B12 and folic acid vitamin replacement should not be underestimated in this population.

The Chugugi and Wootaek data of Gyeongsang-do (Dagu, Jinju, Goseong) were restored from "Gaksadeungnok", the governmental documents reported by the local government to the central during the Joseon Dynasty, and analyzed. The duration of the restored data represents 6 years for Daegu (1863, 1872, 1890, 1897, 1898, and 1902), 3 years for Jinju (1897, 1898, and 1900), and 2 years for Goseong (1871 and 1873). Total number of the restored data was 134, including 83 in Daegu, 25 in Jinju, and 26 in Goseong with the period ranging from March to September. The summer data from June to August accounts for approximately 50% (73 data), while the April data also shows relatively high number of 22, followed by September and March. Most data was collected from March to October, while this time winter data was not found even in October. The rainfall patterns using Chugugi data were investigated. First, the number of days with rainfall by annual mean showed 41 days in Daegu, 39 in Jinju, 33 in Goseong, respectively. In terms of the time series distribution of daily rainfall, the ratio between the number of occurrences with over 40 mm of heavy rainfall and the number of rainy days showed 14 times (8%) in Daegu, 24 (39%) in Jinju, and 4 (6%) in Goseong, respectively. The maximum daily rainfall during the period was recorded with 80mm in Jinju on August 24, 1900. The result of analyzing monthly amount of rainfall clearly indicated more precipitation in summer (June, July and August) with the relatively high records of 284 mm and 422 mm in April, 1872 and July, 1902, respectively, in Daegu, while Jinju recorded the highest value of 506 mm in June, 1898. When comparing the data with those observed by Chugugi in Seoul during the same period from "Seungjeongwonilgi", the monthly rainfall patterns in Daegu and Seoul were quite similar except for the year of 1890 and 1897 in which many data were missing. In particular, in June 1898 the rainfall amount of Jinju recorded as much as 506 mm, almost 4 times of that of Seoul (134 mm). Based on this, it is possible to presume that there was a large amount of the precipitation in the southern region during 1898. According to the calculated result of Wootaek data based on Chugugi observations, the unit of 1 'Ri' and 1 'Seo' in Daegu can be interpreted into 18.6 mm and 7.8 mm. When taking into consideration with the previous result found in Gyeonggi-do (Cho et al., 2013), 1 'Ri' and 1 'Seo' may be close to 20.5 mm and 8.1 mm, however, more future investigations and studies will be essential to verify the exact values.

Objectives : A protocol called "critical pathway" was developed to standardize the management of hospital patients the day after they underwent gamma knife radiosurgery. The quality of improvement in patient outcomes was evaluated. Methods : Critical pathway was developed, according to the regulations of the I hospital, by analyzing the medical records of 22 inpatients who underwent gamma knife surgery within the period from January to April 2011 on the day of the surgery. The study included a group of 22 patients admitted to the hospital the day after they underwent gamma knife radiosurgery, between July and September 2011. The control group included 22 patients who had surgery employing the same method within the period from May to June 2011. To measure the effects on quality improvement, the average length of stay, the execution rate of the hospital discharge notice system, daily hospital revenue, and the satisfaction of the patients and the medical team were assessed. The patient questionnaire employed a four-point Likert scale while the medical-staff questionnaire employed a five-point Likert scale. Result : The average length of stay was significantly shorter in the study group compared to the control group (2.3 days vs. 3.8 days, P<0.05). The execution rate of the hospital discharge notice system was higher in the study group (100% vs. 72%) than in the control group. Daily hospital revenues were higher by 264,178 Korean won in the study group when compared to the control group. The study group showed greater satisfaction of patients compared to the control group based on a four-point Likert scale (P<0.05). The study group showed greater satisfaction in medical team compared to the control group based on a five-point Likert scale (P<0.05). Conclusion : The development and implementation of a critical pathway protocol for hospital admission the day after gamma knife radiosurgery is an effective care process that improves the clinical quality.

Warming trends during winter seasons in East Asian regions are expected to accelerate in the future according to the climate projection by the Inter-governmental Panel on Climate Change (IPCC). Warmer winters may affect short-term cold hardiness of deciduous fruit trees, and yet phenological observations are scant compared to long-term climate records in the regions. Dormancy depth, which can be estimated by daily temperature, is expected to serve as a reasonable proxy for physiological tolerance of flowering buds to low temperature in winter. In order to delineate the geographical pattern of short-term cold hardiness in grapevines, a selected dormancy depth model was parameterized for "Campbell Early", the major cultivar in South Korea. Gridded data sets of daily maximum and minimum temperature with a 270m cell spacing ("High Definition Digital Temperature Map", HDDTM) were prepared for the current climatological normal year (1971-2000) based on observations at the 56 Korea Meteorological Administration (KMA) stations and a geospatial interpolation scheme for correcting land surface effects (e.g., land use, topography, and site elevation). To generate relevant datasets for climatological normal years in the future, we combined a 25km-resolution, 2011-2100 temperature projection dataset covering South Korea (under the auspices of the IPCC-SRES A2 scenario) with the 1971-2000 HD-DTM. The dormancy depth model was run with the gridded datasets to estimate geographical pattern of change in the cold-hardiness period (the number of days between endo- and forced dormancy release) across South Korea for the normal years (1971-2000, 2011-2040, 2041-2070, and 2071-2100). Results showed that the cold-hardiness zone with 60 days or longer cold-tolerant period would diminish from 58% of the total land area of South Korea in 1971-2000 to 40% in 2011-2040, 14% in 2041-2070, and less than 3% in 2071-2100. This method can be applied to other deciduous fruit trees for delineating geographical shift of cold-hardiness zone under the projected climate change in the future, thereby providing valuable information for adaptation strategy in fruit industry.

Photography has been a way of recording a range of images throughout the previous 160 years since its birth in 1839. It has also included the observations and records on the subjects, which is almost same as reality in its outward appearance, various looks of a city and architecture in the daily lives at these places. These pictures provide archaeological and geographical information beyond time and space as well as expressing cultural and artistic images using the creative senses. This thesis analyzes the images of a city and architecture as various angles along with development process of the photograph. The purpose is to examine what viewpoints, methods and concepts have been used to observe the city and architecture. The study will show that photography is a means of artistic expression and a means of indirect understanding of a city and its architecture by early modern photography of the 19th Century.
