This study analyzed the Importance-Performance Analysis (IPA) of purchase behaviors and attributes for Hangwa. The data for this study were collected over 10 days from April 10 through April 19, 2013. For empirical research, married women over the age of 20 in Gwangju with buying experience of Hangwa were surveyed. A total of 172 questionnaires were completed and statistically analyzed by SPSS 18.0 package. Analysis rate was 96.6%. To review Hangwa purchase behaviors, most respondents bought Hangwa four or five times per year for memorial services or ancestral rites. Respondents bought Hangwa at big supermarkets and the types of Hangwa bought were Yukwa and Yakgwa. Their average expenses were 20,000 to 30,000 won per purchase. Among purchase attributes of Hangwa, respondents considered the importance of 'sanitation' (4.76 points) a top priority, followed by 'origin' (4.75 points), 'quality' (4.74 points), 'taste' (4.57 points) and 'appearance' (3.82 points). However in the case of satisfaction, 'sanitation' (3.85 points) was the most satisfying aspect, followed by 'package' (3.82 points), 'amount' (3.80 points), 'appearance' (3.51 points) and 'taste' (3.41 points). According to the IPA results, 'quality' and 'origin' purchase attributes, should be quickly improved. 'Sanitation' and 'taste' should be maintained. This survey found that satisfaction levels for Hangwa purchase attributes had a significant influence on overall satisfaction (F=29.11, p<.001), and especially 'taste' ($\beta$=.42, t=6.69, p<.001) had a meaningful effect on overall satisfaction. In addition, satisfaction levels for Hangwa purchase attributes affected repurchase intention (F=20.05, p<.001). From these results, Hangwa manufacturers should make efforts in product development to induce customers satisfaction and repurchase intention.

This study was conducted to analyze the characteristics of women's body somatotypes by direct measurements. Through the classification of degree of obesity and silhouette, women in their 20s who have a great interest in body somatotype can grasp their real somatotype and recognize their obesity rate and silhouette easily. The results are as follows: 1. Average sizes of subjects for this study were: height 160.3cm, weight 52.2kg, bust 83.7cm, waist 65.7cm, hips 91.1cm. And average values of each body mass index were: BMI 20.3, Rohrer Index 1.27, Vervaeck Index 84.8. 2. For the BMI value, the Average Numeric Index of normal somatotype was the highest, 76.9%. The Rohrer Index of underweight somatotype was 34.3% and the Average Numeric Index was 1.12. In the Vervaeck Index, underweight somatotype was 35.7%, and the average Numeric Index was 79.1, while the overweight somatotype was 7.4% of the Vervaeck Index and 100.8 of the Average Numeric Index. So the index which had the largest range of normal values from the same subjects, was the BMI, then the Rohrer Index, and finally, the Vervaeck Index in that order. 3. In the result of sorting bodies with silhouettes, when drop value were used to sort, N type (normal somatotype) was 69.4%, H type (one has similar sizes in waist size and hips) was 20.4% and A type (one has big hips) was 10.2% in that order. Among people in their early 20s, A type was 12.1%. H type was high, 22.8%, among women in their late 20s. When Sinozaki's method of classifying body types was used, ideal somatotype was 86.6%, A type was 7.4%, I type was 5.6% and X type was 0.5%. Women in their late 20s showed higher rates of ideal somatotype, the rates of A type and I type were lower than women in their early 20s.

In order to investigate the punch properties of some vegetables-cucumber, radish, garlic, ginger and potato-force, distance, and time were measured with a texturometer, and the correlations between compositions and cell characteristics of samples were characterized. Many reflection and rupture points on the force-distance and distance-time curve were observed, and these points appeared when the cells of sample were resisted and yielded against the applied force. They were big and clear at the slow crosshead speed. The regression analysis for force-time and distance-time to the rupture point showed $R^{2}>0.95$. The rupture time and rupure force were 5.63 sec, 4.88 N in ginger and 4.15 sec, 2.00 N in cucumber. The rupture forces become large values at the fast crosshead speed. As cell sizes were increased, the moisture content and rupture distance were increased, while the viscosity of juice, density, regularity of cell, and slope of force-time were decreased. Rupture force, time and distance were decreased at the large specific gravity of samples. The slopes of distance-time curve were inversely proportional to slope of force-time curve.

Objective : Liver cirrhosis is a disease of the liver in which normal cells are replated by scar tissue. Chronic liver disease and liver cirrhosis are the foutth ranked causes of death in Korea. However, clinical data on liver cirrhosis is not accumulated in oriental medicine. Therefore, clinical characteristics of 33 liver patients admitted to Hana Oriental Hospital from May 2004 to May 2005 were studied. Methods : Clinical characteristics of liver cirrhosis, such sex, age, causes, Child-Pugh class, chief complain, abdomen ultrasonography, disease duration, past history, blood test and urinalysis were reviewed. Results : The results of this study were as follows: 1 The distribution of sex and age in our study is similar to already reported statistics. 2. Hepatitis B and alcohol are the major factors to cause the liver cirrhosis. Diabetes and hypertention contribute more to cause than they have in previous histories. 3. Major symptoms are following: fatigue 87.9%, ascites 84.8%, jaundice 78.8%, leg edema 72.7%, dyspepsia 45.5%. 4. Most liver cirrhosis patients have pancytopenia. Standard Deviation accentuates the big differences between total bilirubin and serum amonia. 5. In urinalysis, Urobilinogen 19 patients (57.6%), bilirubin 12 patients (36.4%), blood 15 patients (45.5%) are positive. 11 cases of 15 in blood positive results scored $3{\sim}4+$. Contusions : In oriental medicine, it will be necessary to research and develop oriental medical therapies for liver disease including liver cirrhosis.

Plasma progesterone (P$_4$) concentrations were measured for confirming the estrus observation and for the early pregnancy diagnosis in 130 cows of small farmers. Ultrasonographic examinations were performed from day 30 after artificial insemination to establish the characteristic ultrasonographic appearances of gestational structures in each pregnant stages. Of the 130 cows inseminated, 111 cows (85.4%) were an ovulatory estrus, 12 cows (9.2%) were an unovulatory estrus, and 7 cows (5.4%) were the error of estrus detection, respectively. The accuracy for early pregnancy diagnosis in 111 ovulatory estrus cows achieved when the discriminatory concentration at day 21 after artificial insemination was placed at 3.0 ng-/ml in plasma, was 86.7 % for positive diagnosis and 100% for negative diagnosis, respectively. Pregnancy diagnosis by ultrasonography were performed to evaluate gestational structures from day 30 after artificial insemination in 83 cows. Pregnant cows were 72 of 83 cows. The characteristic ultrasonography of gestational structures in each gestational stages was as follows. The embryo proper was observed within anechoic fetal fluid between 28 and 40 days after insemination, and amnion and embryonic heartbeat was also detected in this period. Between days 41 and 50, embryo proper was detected as an discriminated from head and body, and forelimb buds and hindlimb buds were also observed in this period. Between days 51 and 60, an embryo proper was clearly discriminated from head and body, and fetal movement, forelimb buds and hindlimb buds were observed in this period. Between days 61 and 70, fetus was completely developed, and fetal skeleton, organs and cotyledon were observed. After day 71, each organs of fetus were rapidly developed and a fetus was partially observed in screen because fetus was too big and larger, These results indicate that plasma P$_4$ determination at days 0,6 and 21 after artificial insemination can be utilized for confirming the estrus observation and for early pregnancy diagnosis. Also, ultrasonography was reliable method for early pregnancy diagnosis at day 30 after artificial insemination.

In order to systematically apply major technologies of the 4th Industrial Revolution to aerospace power development, an aerospace technology model is needed. The Propeller Model, which is an existing aerospace model, is a concept that operates a combination of altitude, speed, and distance, which are basic characteristics of aerospace. However, in the era of the 4th Industrial Revolution, a new model is needed because numerous technologies are used in convergence. In this paper, a jet engine model is proposed as a new aerospace technology model. Also, we propose a procedure for creating future aerospace weapon systems based on aerospace technology modeling, not on operational capability. The utilization of future battlefields and the study of the concept of advanced weapon systems in developed countries can create a new concept of weapon systems.

Recently, wireless network has been playing an important role in communication system and the applications have become wider with its big technological leap. In defence sector, there are some attempts to use wireless networks to go beyond the wire system. Especially, most internal space of the warships have the wired communication system, which are complicated and inefficient. In this paper, we measure and make a channel model about the internal parts of the warship which contain compartments and corridors including many differences from general indoor environment for establishing wireless networks in warship's internal space. In the unique environment made of metal, we measure 2.4GHz signals using continuous wave(CW) and analysis the environment to present indoor path-loss model for comparing with results from the ray-tracing tool. Moreover, we draw the conclusion that the environment of warships has a wide difference from conventional environments and put the results to practical use in warship's internal space.
