To investigate the effect of polyethylene film packaging and $CO_2$ treatment on tomatoes during storage, the gas composition in film, weight loss, the changes of color, hardness and several components were measured. The concentrations of $CO_2$ and $O_2$ in film were changed rapidly in early stage, but it kept a constant level after 7 days of storage. In 0.06 mm polyethylene film, $CO_2$ and $O_2$ concentration was kept a level of $4{\sim}6%$ respectively. The increase in $C_2H_2$ concentration was delayed in thick and $CO_2$ treated film. The rate of weight loss was 4% in non-packed tomatoes, but it recorded about 1% in 0.06 mm polyethylene film. Titratable acidity, pH and soluble solids were changed slightly, but the obvious differents were not observed according to film thickness and $CO_2$ treatment. The value of tomatoes was increased but L and b values were not changed greatly during storage. These color changes were restricted by 0.06 mm film and $CO_2$ treatment. The firmness and content of ascorbic acid were reduced during storage but it restrained by $CO_2$ treatment and film packaging. Sugar of tomatoes were composed of glucose, fructose and a very small amount of sucrose, and they were changed little during storage.

This study conducted to find out the best way to prolong green period of Zoysiagrass and Cool-season grass from 1999 to 2001 in Korea. Treatments were control, vinyl, black shade net, green shade net, black shade net+vinyl, green shade net+vinyl, vinyl+black shade net, and vinyl+green shade net for Zoysiagrass. For cool-season grass, treatments were control, non-punched vinyl and punched vinyl. Data on temperature, light intensity, humidity, leaf color and chlorophyll were collected. Plot size was 2 by 2 and the experiment was conducted using completely randomized design with three replication. Zoysiagrass Green period of Zoysiagrass depended on temperature and light intensity than humidity. Effective method of prolongation of green period in Zoysiagrass was to covered it with vinyl during early October to early November, and then using vinyl+black shade net from end of November. Cool-season grass Effective method of prolongation of green period in Cool-season grass was by covering it with vinyl during mid-November to mid-December, and then using vinyl+black shade net from end of December.

At its thirty-second session in 1999, the UNCITRAL had before it the requested note entitled "Possible future work in the area of international commercial arbitration." After concluding the discussion on its future work in the area of international commercial arbitration, it was agreed that the priority items for the working group should be conciliation, requirement of written form for the arbitration and enforceability of interim measures of protection. the Commission entrusted the work to the Working Group on Arbitration which held its thirty-second session at Vienna from 20 to 31 March 2000. The Working Group discussed agenda item 3 on the basis of the report of Secretary General entitled "Possible uniform rules on certain issues concerning settlement of commercial disputes : conciliation, interim measures of protection, written form for arbitration agreement." At its thirty-three session in 2000, the UNCITRAL had before it the report of Secretary General on agenda item 3 discussed by the Working Group. The Working Group discussed the issues relating to certain aspects of conciliation proceedings ; (1) Admissibility of certain evidence in subsequent judicial or arbitral proceedings ; (2) Role of conciliatior in arbitration or court proceedings ; (3) Enforceability of settlement agreements reached in conciliation proceedings ; (4) Other possible items for harmonized treatment : a) Admissibility or desirability of conciliation by arbitrators b) Effect of an agreement to conciliate on judicial or arbitral proceedings c) Effect of conciliation on the running of limitation period d) Communication between the conciliator and parties ; disclosure of information e) Role of conciliator. It was generally considered that decisions as to the form of the text to be prepared should be made at a later stage when the substance of prepared solutions would become clearer. However, it was noted that model legislative provisions seemed to be appropriate form for a number of matters proposed to be discussed in the area conciliation. There was general support in the Working Group for the proposition to perpare a legislative regime governing the enforcement of interim measures of protection ordered by arbitral tribunals. It was generally considered that legislative regime should apply to enforcement of interim measures issued in arbitration taking place in State where enforcement was sought as well as outside that State. It was generally observed that there was a need for provisions which conformed to current practice in international trade with regard to requirements of written form for arbitration agreement. The view was adopted by the Working Group that the objective of ensuring a uniform interpretation of the form requirement that responded to the needs of international trade could be achieved by : preparing a model legislative provision clarifying, for avoidance of doubt, the scope of article 7(2) of the UNCITRAL Model Law on International Commercial Arbitration : and adopting a declaration, resolution or statement addressing the interpretation of the New York Convention that would reflect a broad understanding of the form requirement. There was general agreement in the Working Group that, in order to promote the use of electronic commerce for international trade and leave the parties free to agree to the use of arbitration in the electronic commerce sphere, article II(2) of the New York Convention should be interpreted to cover the use of electronic means of communication as defined un article 2 of the Model Law on Electronic Commerce and that it required no amendment to do that. The UNCITRAL may wish to consider to the desirability of preparing uniform provisions on any of those issues concerning conciliation and arbitration proceedings, possibly indicating whether future work should be towards a legislative text or non-legislative text.

Silage yield and nutritional values of a locally collected Korean corn line with high tillering and earing characteristics were investigated at plant densities from 2778 to 8333 plants/ l0a. This line and a non-tillering and nonprolific corn as a check were grown at four plant densities and at three planting dates. The Korean local line abbreviated as MET had the highest dry matter per l0a. The highest dry matter of the MET line compared with the check hybrid was due to the highest dry leaf weight of the MET line. The highest dry leaf weight of the MET line was due to the increased number of tillers of the MET line. Other plant parts such as ear weight, kernel weight and cob weight of the MET line were lower than those of the check hybrid. The dry husk weight per l0a of the MET line was higher than that of the check hybrid, probably due to the increased number of ears in the MET line. The total embryo production per 10 a of the MET line was significantly higher than that of the check hybrid. The increased portion of embryo of the MET line is probably responsible for the higher TON values of the MET line. No interaction between variety x planting dates or planting density was found, indicating that the MET line and check hybrid were both the same in effects of planting dates and densities. Both line and hybrid showed the highest dry matter production when the planting density was high and planting dates was early. When silage was made from either MET line or check hybrid the nutritional values in terms of crude protein, crude fat, fiber, and ash contents of the MET line were similar to those of the check hybrid. But the TON of the MET line was higher than that of the check hybrid, while the OCP of the MET line lower than that of the check hybrid. Amino acid contents of the MET line were also comparable to those of the check hybrid, while lysine content of the MET line was 10% higher than that of the check hybrid.

Purpose: To evaluate the prevalence and clinical manifestations of various glomerulonephritis (GN) in children, a clinicopathological anlysis of 310 biopsied cases were performed. Method: We conducted retrospective study with review of histopathologic findings and clinical manifestations of the 310 cases diagnosed as glomerulonephritis by percutaneous renal biopsy which were done between January 1986 and December 1996 at department of pediatrics, Pusan Paik hospital. Results: 1) Male to female ratio was 1.54:1 and the range of age was from 13 months to 15 years 10 months. 2) Among these, 217 (70.0%) patients were belong to primary GN and 93 (30.0%) patients were belong to secondary GN. As a whole, the most common pathologic diagnosis was minimal change lesion (MC, 32.6%), which was followed by IgA nephropathy (IgAN, 15.8%), $Henoch-Sch\"{o}nlein$ purpura nephritis (HSPN, 13.5%), Poststreptococcal glomerulonephritis (PSAGN, 8.1%). 3) Clinical manifestations of patients were asymptomatic urinary abnormality (43.2%), nephrotic syndrome (41.0%), acute glomerulonephritis (14.2%), chronic glomerulonephritis (1.0%), rapidly progressive glomerulonephritis (0.6%). 4) In primary GN, the most common pathologic diagnosis was MC (46.5%), IgAN (22.6%), thin glomerular basement membrane (GBM) disease (7.8%), membranoproliferative glomerulonephritis (MPGN, 5.5%), mesangial proliferative glomerulonephritis (MesPGN,4.6%), focal segmental glomerulosclerosis (FSGS, 4.6%), membranous nephropathy (MN, 0.9%), sclerosing glomerulonephritis (SCGN, 0.9%), crescentic glomerulonephritis (CreGN, 0.5%) and non-specific glomerulonephritis (NonspGN, 6.0%). 5) Major causes of secondary GN were HSPN (45.2%), PSAGN (26.9%), hepatitis B associated glomerulonephritis (HBGN, 17.2%), lupus nephritis (LN, 6.5%), Alport syndrome (2.2%), hemolytic uremic syndrome (1.0%), fibrillary glomerulonephritis (1.0%) in descending order. Conclusions: There are some differences of the results of clinicopathological stuidies of glomerulonephritis in children because of its different indications of renal biopsy, pathologic classification of renal disease and methods of analysis among investigators. In order to establish more reliable data of incidence and classification of childhood glomerulonephritis in Korea, multicenter cooperative study were necessary.

Objectives : This study was conducted to investigate the prevalence of victims of bullying and the demographic characteristics of victims, and their related psychopathology, in a Korean nationwide sample of youths in middle and high school over a one month period. Methods : During the autumn of 2009, students in the 7th to 12th grades at 23 secondary schools participated in a nationwide, cross-sectional study. The study subjects completed the Adolescent Mental Health and Problem Behavior Screening Questionnaire-II (AMPQ-II) and Symptom Checklist-90-Revision (SCL-90-R). Based on the data acquired, descriptive statistics, correlation coefficients and multiple logistic regression analysis were performed. Results : Among the 3364 participants, 2272 (67.54%) completed the questionnaire. The prevalence of victimization was 28.9%. Male gender was positively associated with victimization, and grade level was negatively related to victimization. The AMPQ-II bullying score (Factor 4) was significantly (p<.001) and positively correlated to the AMPQ-II student total score (r= 0.50), Worry and thought (Factor 1 ; r=0.38), Mood and suicide (Factor 2 ; r=0.31), Academic and Internet-related problems (Factor 3 ; r=0.24), Rule violations (Factor 5 ; r=0.23), and AMPQ-II teacher total score (r=0.11). Somatization (r=0.23), Obsessive-compulsive behavior (r=0.24), Interpersonal sensitivity (r=0.30), Depression (r=0.33), Anxiety (r=0.26), Hostility (r=0.30), Phobic anxiety (r=0.22), Paranoid ideation (r=0.36), and Psychoticism (r=0.31) results from the SCL-90-R were also found to be positively related to the AMPQ-II bullying score, and remained significant after adjusting for age and gender. A total of 26% of the victims reported suicidal ideations as compared to 9% of non-victims over the month prior to the evaluation ($x^2$=119.595, df=1, p<.001). The multiple logistic regression analysis indicated that the AMPQ-II bullying score significantly increased the risk of suicidal ideation [Exp(b)=1.55, df=1, p<.001] after adjusting for age and gender. Conclusion : School bullying was highly prevalent among Korean middle and high school students. This study provided strong evidence that suicidal ideation and psychopathology were serious problems among the victims of bullying.

In the past twenty years, there has been a rapid increase in the volume of traffic in Korea due to the Korean great growth of the Korean economy. Since transformation provides an infrastructure vital to economic growth, it becomes more and more an integral part of the Korea economy. The importance of coastal shipping stands out in particular, not only because of the expansion limit on the road network, but also because of saturation in the capacity of rail transportation. In spite of this increase and its importance, coastal shipping is falling behind partly because it is givenless emphasis than ocean-going shipping and other inland transportation systems and partly because of overcompetition due to excessive ship tonnage. Therefore, estimating and planning optimum ship tonnage is the first take to develop Korean coastal shipping. This paper aims to estimate the optimum coastal ship tonnage by computer simulation and finally to draw up plans for the ship tonnage balance according to supply and demand. The estimation of the optimum ship tonnage is peformed by the method of Origin -Destimation and time series analysis. The result are as follows : (1) The optimum ship tonnage in 1987 was 358, 680 DWT, which is 54% of the current ship tonnage (481 ships, 662, 664DWT) that is equal to the optimum ship tonnage in 1998. this overcapacity result is in excessive competition and financial difficulties in Korea coastal shipping. (2) The excessive ship tonnage can be broken down into ship types as follows : oil carrier 250, 926 DWT(350%), cement carrier 9, 977 DWT(119%), iron material/machinery carrier 25, 665 DWT(117%), general cargo carrier 17, 416DWT(112%). (3) the current total ship crew of 5, 079 is more than the verified optimally efficient figure of 3, 808 by 1271. (4) From the viewpoint of management strategy, it is necessary that excessive ship tonnage be reduced and uneconomic outdated vessels be broken up. And its found that the diversion into economically efficient fleets is urgently required in order to meet increasing annual rate in the amounts of cargo(23, 877DWT). (5) The plans for the ship tonnage balance according to supply and demand are as follows 1) The establishment of a legislative system for the arrangement of ship tonnage. This would involve; (a) The announcement of an optimum tonnage which guides the licensing of cargo vessels and ship tonnage supply. (b) The establishment of an organization that substantially arrangement tonnage in Korea coastal shipping. 2) The announcement of an optimum ship tonnage both per year and short-term that guides current tonnage supply plans. 3) The settlement of elastic tariffs resulting in the protect6ion of coastal shipping's share from other tonnage supply plans. 4) The settlement of elastic tariffs resulting in the protection of coastal shipping's share from other transportation systems. 4) Restriction of ocean-going vessels from participating in coastal shipping routes. 5) Business rationalization of coastal shipping company which reduces uneconomic outdated vessels and boosts the national economy. If we are to achieve these ends, the followings are prerequisites; I) Because many non-licensed vessels are actually operating and threatening the safe voyage of the others in Korea coastal routes, it is necessary that those ind of vessels be controlled and punished by the authorities. II) The supply of ship tonnage in Korean coastal routes should be predently monitored because most of the coastal vessels are to small to be diverted into ocean-going routes in case of excessive supply. III) Every ship type which is engaged in coastal shipping should be specialized according to the characteristics of its routes as soon possible.

This study was carried out to investigate the effects of red yeast rice addition on the physical characteristics of sourdough starters ($SD1{\sim}4$) and the quality characteristics of sourdough bread (CSB, $SDB1{\sim}3$). Moisture contents of red yeast rice, wheat flour, and rye flour were 6.15, 12.53, and 8.56%; ash contents were 0.15, 0.44, and 1.64%; protein contents were 7.30, 12.57, and 11.18%; crude lipid contents were 0.97, 1.16, and 2.49%, respectively. The pH decreased with increasing red yeast rice addition. Reducing sugar and total sugar increased with increasing red yeast rice addition. Lactic acid bacteria were not detected from 0 day for all samples and was maximum on the 2nd day. The yeast counts of SD1 were not detected from $0{\sim}4th$ day, but $SD2{\sim}4$ increased until the 3rd day. Peak time, peak value, and width of tail of CSB were higher than $SDB1{\sim}3$, and they increased with increasing red yeast rice contents of sourdough. The fermentation expansive power of $SDB1{\sim}3$ was higher than that of CSB. Baking loss and specific volume of SDB1 were higher than other samples and when baking loss of CSB and SDB1${\sim}$3 increased, the specific volume increased. L values decreased with increasing red yeast rice contents of sourdough bread whereas, a and b values increased. Springiness and brittleness of CSB and gumminess of SCB1 were lower than other samples. Springiness, brittleness, and gumminess increased with increasing red yeast rice content of sourdough bread. The sensory evaluation indicated that color, hardness, springiness, sweetness, and sourness increased with increasing red yeast rice content of sourdough bread. Aircell non-uniformity of SDB1 was lower than other samples, whereas off-flavor was higher than other samples.

Purpose: This study analyzed the difference in survival time of patients with delirium according to sedative medication. Methods: From January 2012 through December 2013, a retrospective cohort study was performed using the electronic medical records (EMR) of Pusan National University Hospital. Among 900 patients who died from cancer, we selected 240 who suffered delirium based on the EMR. The Nu-DESC delirium screening test was used to diagnose delirium. Results: The median length of delirium period was five days. Delirium characteristics were dominated by inappropriate behaviors (35.0%). Sedatives were administered in 72.1% of the cases. The most frequently used sedative was haloperidol which was used in 59.6% of cases. The delirium period significantly differed by patients' age (F=3.96, P=0.021), cancer type (F=3.31, P=0.010), chemotherapy (t=-3.44 P=0.001). The average survival time was 16.85 days for the sedative medication group and 9.37 days for the non-medication group, which, however, was not significant (t=1.766, P=0.079). Conclusion: In this study, the use of sedatives did not affect patients' survival time. Thus, appropriate sedative medication can be positively recommended to comfort terminal cancer patients and their families.
