The purpose of this study was to carry out comparative analysis on the world major liner shipping companies' ship investment strategy using Fuzzy-AHP model. In this study, the ship investment factors were firstly selected by literature review and finally adopted them by in-depth interview with experts who had working experiences over 15 years in the field of shipping business. As suggested in the previous research, the liner shipping companies have been classified into four types such as 'ship investment irrelevant to market trend'(Type1), 'ship investment before market rise'(Type2), 'market decline after participation in excessive orders'(Type3), 'avoidance of ship investment during market rise'(Type4) and the comparative analysis were conducted among four ship investment types. According to the results of analysis, ship investment priority in Type1 was freight rates(0.132), price of used ship(0.121) and fleet(0.103). The priority in Type2 was freight rates(0.134), need for ship owner(0.113) and public funding(0.109). Type3 put its priority in freight rates(0.173), fleet(0.169) and the changes in international circumstances(0.121). Type4 considered freight rates(0.239), fleet(0.232) and oil price(0.150) as its priority.

This paper is intended to find out what kinds of fruits are mentioned in the Bible and how they were used in those days. It has also analyzed in what terms they are expressed in the Korean Version of the Bible and studied agricultural regulations involved in the religion, and allegorical uses of the fruits. Olives were the primary fruit in the economy of the ancient times, followed by figs and vines. In addition, there are mentioned in the Bible almonds, apples, dates. mulberries and pomegranates. Olive trees have been grown for more than six thousand years. The Hebrew word. Zayit is mentioned in the Bible more than fifty times. Olive trees are not so beautiful in themselves but as they give us humans abundant reap and a lot of oil, they have been thought to be beautiful. Olive trees grow well on the seaside in the salty air and fog. Vines began to grown as early as in the Bronze Age(the period of 3000 to 2000 B.C.). In Northern Greece, grape seeds were found to belong to the year 4500 B.C. or so. The vine gardens produced raisins and wine as well as vines. Figs are the fruit which are first mentioned in the Bible(Genesis 3:7) and they were the precious product of the Palestine people, which is described in Deuteronomy 8:8. Figs are sweet and watery and can easily quench thirst on hot summer days. They were used for cookies and wine in the raw or dried state. An apple, which is tappuah in Hebrew, is mentioned as 'Sagwa' six times in the Revised Korean Version, and in the Korean Joint Version it is twice mentioned as 'Sagwa' and as 'Neungum' four times. In ASV and KJV, 'apple' appears eleven times. which is because' the apple of eye' is translated in the 'Nun-dong-ja(the pupil of the eye)'In the Korean Version. 'Sagwa(apple)'of Proverb 25:11, the Song of Songs 2:3, 2:5, 7:8, 8:5 and Joel 1 :12 have been thought to be doubtful. because apple trees cannot be grown in the areas mentioned in the Bible. Some maintain that the apples in the Bible refer to apricots(Prunus armeniaca, Citrus medica L.) or golden oranges (Citrus sinensis L. Obsbeck) which is confusing. In the Revised Korean Version, 'Salgu(apricots)' appears eight times while ASV and KJV translate almond into 'Salgu'. So since translating a genuine apricot into 'Salgu' can be confusing, a great care should be taken in the translation into Korean. Some hold that as some papyri arround the year 1200 B.C. describes pomegranate, apple, olive and fig trees growing on the Nile delta, tappuah rightly refers to 'Sagwa(apple)' In the Korean Joint Version, Sagwa and Neungum are used together to refer to the same fruit, which should be avoided. It is desirable to use the same word for the same thing. Sagwa' showing up six times In the HeL.Ised Korean Version should all be replaced by 'Neungum' Dates symbolized peace and abundance were used for food in the raw or dried state, and were made into honey. Pomegranates can be eaten in the raw state and be used for sherbets and wine. Juice made of promegranates can be mixed with wine and drunk.

This report includes basic data on nutrition education for Chinese adolescents living in Korea. A total of 183 Chinese adolescents living in Incheon participated in the survey. Body composition was analyzed by the Inbody 4.0., and questionnaires on personal dietary behavior were administrated. When compared with the body measure indices of Korean adolescents, we found that height was similar, but weight greater ($5{\sim}12 kg$) among the participants. Regarding obesity, 30.0% of all students were obese (BMI>25), especially the high school boys (42.0%). But in the case of middle school boys, the rates of obesity and under weight (BMI<18.5) were the same (both of them at 22.9%). The average WHR (Waist Hip Ratio) of the female high school group (0.9) was over the normal range. The average percent body fat for each group was also over the normal range. The percentage of students having breakfast everyday was 52.2%, and the rate of skipping breakfast was 25.0%. In the obesity group, the rate of skipping breakfast was remarkably high (P<0.05). Because lunch service was not available at the schools, a lunch box from home was the most popular pattern (43.1 %), but eating out was also popular at 36.6%. For the male high school students, the eating out rate was 62.8%. Since many have-lived in Korea for a few generations, the students' eating practices were much closer to the Korean pattern. For their ordinary meal pattern, 96.0% of the students included Korean foods. however, for New Years Day, the rate of having Gyo-Ja was 75.2%, and having Wol-Byung at Choo-seok was 78.6%, showing that the Chinese tradition still remains. In the case of food preferences, the percentage having Kimchi everyday was 62.1 %, but those drinking green tea was 13.1 %. For cold drinks, the rate for drinking them more than twice per week was 71.6%. The most preferred cooking method was frying with oil (50.6%). Among the students who had visited China (or Taiwan), the rate for 'bad food familiarity' was 37.0%, and the rate for 'did not know Chinese traditional course menus' was 71.3%. As a result of combining eating practices from both China and Korea, and the absence of lunch service in Chinese schools, students are showing bad dietary behaviors. therefore, it is necessary to provide proper nutrition education and a system for lunch service in Chinese schools.

We investigated developmental stages of egg and early life history of the Korean indigenous fish, Korean Chub Zacco koreanus from the South Han River in 2011 for phylogenetic study and conservation of this species. Eggs of Zacco koreanus were artificially fertilized by the dry method in the laboratory. The fertilized eggs were demersal, almost spherical in shape, transparent and unpigmented, with a pale yellow yolk, and no oil globule and average $3.09{\pm}0.07$ mm (n=10) in diameter. The hatching of the embryo took place in about 68 hrs after fertilization under water temperature of $20.0{\sim}23.0^{\circ}C$ and the newly hatched larvae were average $10.30{\pm}0.40$ mm (n=10) in total length (TL). Six days after hatching, the larvae grew up to $16.12{\pm}0.42$ mm (n=8) in TL and york sac absorption, mouth and anus opening were shown postflexion larvae stage. 17 days after hatching, most of fin-rays appeared at $18.21{\pm}0.38$ mm (n=6) in TL and brown spot appeared on the abdomen. 27 days after hatching, the larvae were brought up to $20.01{\pm}1.12$ mm(n=5) in TL and all their fin-rays were formed. 120 days after hatching, the larvae (juvenile) were $23.29{\pm}3.12$ mm (n=10) in TL and their body shape and color pattern were similar to the adult fish.

We determined the morphologic characteristics (body weight and abdomen inflation degree) of the mother fish of sevenband grouper, Epinephelus septemfasciatus producing the healthy eggs. Experimental fish were chosen from the reared fish in the sea cage for 6 years. The fish were divided into four size groups by body weight: 4.0~5.0, 5.0~6.0, and 6.0~7.0 kg and four stages (I~IV) by the abdomen inflation degree. After hormone treatment, we observed the ovulation amount of induced eggs, rate of buoyant, fertilization, embryonic survival, and hatching. Egg and oil globule diameter was measured. In order to observe gonadal development, we calculated gonadosomatic index (GSI) and conducted its historical analysis. The ovulation occurred from all experimental fishes over 5.0 kg. The rate of buoyant, fertilization, and embryonic survival was the highest in 6.0~7.0 kg. Hatching rate was the highest in 5.0~6.0 kg. Stage I and II did not induce ovulation. GSI was $0.31{\pm}0.10%$ in stage I, $0.74{\pm}0.25%$ in stage II, $4.68{\pm}0.40%$ in stage III and $6.86{\pm}0.12%$ in stage IV. The rate of buoyant, fertilization, embryonic survival and hatching was the highest in stage III.

Most of the sulfur is obtained from desulfurization of natural gas and crude oil. In Korea, more than 120 tons of sulfur are produced by refinery, and about 50 % of the produced sulfur is used as a raw material for the production of fertilizer and sulfuric acid. Modified sulfur is manufactured from excessive sulfur that could be used to improve concrete properties, and this study evaluated concrete strength and durability that contains modified sulfur. Flexural and compressive strengths of concrete with sulfur modified polymer were comparable to those of OPC concrete with mixing water at similar temperatures, while the strengths increased a little as mixing water temperature increased. It was also confirmed that the resistance to freeze-thaw damage was more dependent on entrained air characteristics obtained by a proper use of air entraining agent than on the use of sulfur modified polymer. When concrete was immersed in 5 % sulfuric acid, the rate of reduction in compressive strength of OPC concrete was less than 1/4 of the strength reduction of concrete with sulfur modified polymer. Also, the resistance of concrete with sulfur modified polymer to scaling due to the use of de-icing salt was evaluated as Class 1, while that of OPC concrete was evaluated as Class 4, as aggregates were exposed. Accordingly, it is believed that sulfur modified polymer could be effectively used for bridge deck concrete since sulfur modified polymer improves the durability of concrete.

This study was designed to examine nutrition label use, self-efficacy, snacking and eating behaviors of middle school students, and to investigate if these characteristics were different by nutrition label use. A cross-sectional survey was conducted to 348 middle school students in Kyunggi, Korea. About a third of subjects read nutrition labels when they purchased snacks/packaged foods. Most nutrition label users were interested in reading information on calories, fat and trans-fat. Self-efficacy of eating/selecting snacks or general nutrition behavior was moderate (mean score: 44.4 out of 60), with significantly higher score in nutrition label users compared to nonusers (p < 0.001). Nutrition label users felt more confident in 9 items out of 15 items of self-efficacy, such as "taking fruits instead of cookies/candy for snack" (p < 0.001), "choosing milk instead of soft drink" (p < 0.01), "not having snacks after dinner" and "avoiding processed foods for snacks" (p < 0.05). Subjects had snacks 1.3 times a day, and nutrition label nonusers consumed snacks more frequently than the counterparts (p < 0.01). About 55% of nutrition label users and 64.7% of nonusers mainly purchased snacks for themselves (p < 0.05). Commonly purchased snacks by adolescents were ice cream, cookies/chips, breads and ramen. Major considerations in purchasing snacks were taste (46.9%) and price (34.6%). In selecting snacks, the influence of friends and parents was greater than the other sources. Based on eating frequency of snacks, nutrition label users were more likely to consume healthy snacks, such as fruit juices, vegetables, milk, yogurt, and potato/sweet potato than nonusers (p < 0.05). Eating behaviors measured by 15 items scored 33.6 out of 45. Nutrition label users showed better eating behaviors, such as "eating meals slowly", "eating foods cooked with plant oil", and "eating out less frequently" (p < 0.05). Study results showed that majority of adolescents did not read nutrition labels, selected snacks for themselves and had somewhat unhealthy foods for snacks. This study also showed the differences in self-efficacy, snacking and eating behaviors between nutrition label users and nonusers. In nutrition education, it is necessary to stress the importance and skills for reading nutrition labels. It is also needed to help adolescents to select healthy snacks and have desirable eating behaviors, as well as increasing self-efficacy.

Traditionally, the Sozialdemokratitische Partei Deutschlands(SPD) guards strictly radical welfare conception and intends to support the disabled with universal welfare-political instruments. After the oil-shock in 1973, European welfare states including Germany had experienced stark financial crisis because of economic unstability and increasing social expenditure. The political direction of SPD has been gradually changed. This transformation has been reflected automatically on the welfare policy for the disabled. In Germany, Gerhard Schroeder who leads the SPD governs since 1998. The Schroeder's new conception of welfare policy is known as the Third Way("neue Mitte") that the social economic structure intends to neo-liberalistic trend. The concern on the employment policy for the disabled has grown recently in neo-liberalistic age, but research on German employment policy for the disabled is very limited in quantity and depth. The main purpose of this study is to examine how the employment policy for the disabled of Schroeder-government has been developing in Germany. And this paper evaluates the effect of transforming policy. Based on this evaluation, this paper attempts to manifest the problem of Korean employment policy for the disabled and to find the implications of German model.

Background: Nucleolar organizer regions(NORs) are chromosomal segments encoding for ribosomal RNA and associated with argyrophilic nonhistone protein. Ribosomal RNA genes ultimately direct ribosome and protein synthesis, and it has been suggested the numbers of NORs detected in the cell may reflect nuclear and cellular activity. This study was performed to evaluate the applicability of AgNORs to the diagnosis of squamous cell carcinoma of the lung. Method: The one step silver methods(AgNORs) was used to stain NORs in the routinely processed, formalin fixed, paraffin embedded sections of 36 cases of squamous cell carcinoma of the lung obtained by surgical resection of primary tumor. In each specimen, 100 tumor cells and 100 normal cells adjacent to the tumor chosen at random were examined under an oil immersion lens at a magnification of ${\times}1000$. The mean number of AgNORs per nucleus was calculated for each specimen. Results: The mean number of AgNORs per nucleus(mAgNORs) of normal bronchial epithelium and squamous cell carcinoma of the lung was $1.74{\pm}0.25$ and $4.05{\pm}0.80$, respectively. The difference of mAgNOR between normal and tumor tissue was statistically significant(p<0.001). There was no statistical difference among tumors of different stages. The difference of mAgNOR between normal and tumor tissue was statistically significant in each TNM stage(p<0.05). Conclusion: Mean AgNOR count may be used as a useful marker for the differential diagnosis of benignancy and malignancy, and proliferative activity of the cell in squamous cell carcinoma of the lung. But there was no statistical difference in mean AgNOR count among tumors of different surgical stages. Further studies for the application of mAgNORs to the diagnosis of other histologic types and cytologic specimens of the lung cancer are needed.

Floating and hatching rates, size and survival activity index(SAI) of spawned eggs of red spotted grouper, Epinephelus akaara were studied to understand egg qualities during the spawning periods in 1992, 1993 and 1995. The fish spawned from mid-July to mid-August when temperature ranged 23~$28^\circC$. Floating, fertilization and hatching rates were higher in the eggs from early to middle than those from late during the spawning period. SAI ranged 1.8~9.6, and it was closely related to survival rate until mouth operning time (SMOT). Egg diameter decreased gradually with the time of spawning, while diameter of oil globule was constant during the spawning periods. Induced spawnings were carried out with one injection of HCG over 5, 000 IU/kg body weight. Floating, fertilization and hatching rates of the induced spawning eggs were higher than those of untreated ones. Thus, induced spawning method with HCG was recommended for collecting fertilized eggs in bulk. Optimal time for the collection of high quality eggs was supposed to be from early to middle during the spawning periods. Considering that egg qualities were vulnerable within the period, hatchability, incidence of malformed larvae, SMOT and SAI were factors to be considered together to get good quality of eggs.
