본 연구에서는 항만의 주요고객인 선사를 대상으로, 국외선사와 국내선사로 세분화하여 속성의 중요도와 항만 선호도 차이를 비교분석하였다. 컨조인트 분석 결과 국내선사와 국외선사 간의 항만선호도에서 분명한 차이를 보였으며, 이러한 차이는 기항지와 환적항에서 동시에 나타났다. 국외선사들은 환적항으로서 상하이항을 가장 높게 평가했지만, 국내선사들은 부산항을 상하이항보다 높게 평가했다. 또한, 기항지 선호도 비교에서도 비슷한 결과를 나타냈다. 이러한 연구결과는 국내외 선사에 따라 항만 선호도가 다르기 때문에 집단별로 구분하여 평가할 필요가 있음을 의미한다. 또한, 이를 바탕으로 타항만에 비해 경쟁위위에 있는 부산항의 선호도를 유지하기 위해서는 지속적인 목표(Target) 마케팅이 필요하며, 주요 목표(Target)는 항만의 주요 고객인 선사임을 암시한다.

Fifty-two wether lambs weighing 30 kg were randomly assigned to 5 treatment groups; 1) initial slaughter. 2) control-maintenance (CON-MT), 3) control-ad libitum (CON-AL), 4) cimaterol-maintenance (CIM-MT) and 5) cimaterol-ad libitum (CIM-AL). Ad libitum-fed animals had free access of a high-concentrate diet, whereas maintenance animals were restricted in feed intake to maintain the initial weight of 30 kg for 90 days. Cimaterol was administered in the feed at 10 mg/kg. Regardless of feeding level, the administration of CIM improved carcass weight (p < .05), dressing % (p < .01), longissimus muscle area (p < .01), leg conformation and muscling (p < .01), USDA yield and quality grades (p < .01) and protein concentration (p < .01) in carcass as well as in muscle. Cimaterol feeding decreased organ wt (p < .01), baekfat depth (p < .01), intramuscular fat and overall fatness. Cimaterol was effective for muscle accretion even under restricted feeding condition. The greater accretion of muscle was the result of the hypertrophy of both type I and type II muscle fibers but the hypertrophy of type II fiber (110%) was much greater than that of type I fiber (37%). Cimaterol feeding decreased muscle DNA concentrations but the number of nuclei per muscle fiber was not changed, indicating that the lower DNA concentration was due to the dilution effect caused by the hypertrophy of muscle fiber. As evidenced by lower flank streaking, lower marbling and darker muscle, CIM feeding adversely affected meat quality. Meat tenderness was also adversely affected, resulting in significantly (p H .01) tougher meat in CIM-fed animals.

Marine casualities in the high sea are mainly classified into the breakage of hull and capsize , of which the latter occurs frequently to a small craft and container vessels by extreme rolling. The aim of this study is to develop shiphandling techniques for the prevention of ship's large rolling by way of evaluating dangerous degree of rolling in heavy weather. In this study, rolling motion is analized by using statistical method as follow : (1) 8 sample ships is presented for calculation. (2) Analized sea state are Beaufort scale 7 and 10 (wind velocity 30kts and 50kts respectively) and significant wave height is put as 5.2m and 11.2m. (3) The formula recommended by International Towing Tank Conference (ITTC) is used to calculated the wave spectrum. The results of this study are as follow : The results of this study are as follow : (1) Most of the vessels with beam of 20 meters or less was found to be capized in the waves abeam under the sea condition of Bearfort scale7(30kts). (2) For the vessels range 20m to 30m was found safe under the sea conditions of Bearfort scale 7(30kts) and imminent danger under the sea condition of Beaufort scale 11(50kts). (3) It is proved that any vessel could be capsized by heavy rolling regardless of vessel's size whenever the motion is synchronized with waves abeam. This study concludes that the navigator, especially at night , must anticipate the exact wave direction, referring to the wether report and coastaline, not to lay the vessel in the serial wave abeam.

Three growing wethers were used to investigate the differences in nitrogen (N) retention, blood plasma metabolite concentration and energy-yielding nutrient supply to muscle and adipose tissue. The wethers were fed one of three diets: timothy hay with concentrate (THD), Italian ryegrass with concentrate (IRD), and rice straw with concentrate (RSD) for 11 days. The experimental diets were adjusted to the animals to provide 100 g of daily gain. The triglyceride (TG) concentration of blood plasma in arterial and portal veins was higher with THD and IRD than with RSD. Conversely, the available amount of TG in tissues was higher with IRD. The daily amount of glucose and non-esterified fatty acids (NEFA) supplied to muscle tissue and adipose tissue was numerically higher with THD than IRD or RSD. Although N retention did not differ among the diets, it was numerically higher with THD than with IRD or RSD. The results suggest that the difference in the amount of glucose and NEFA delivered to muscle tissue may reflect the N retention in response to forage based diets.

Korean High Speed Train(KHST) has been tested on the high speed test line in Osung site of Korea High Speed Rail Construction Authority (KHRC). since it was developed as G7 Project Plan In 2002. This paper introduces the dynamic test devices in KHST and shows the comparison between the results of test and theoretical computing results which derive from the new model for KHST dynamic behavior. Previous computer simulation model for KHST was developed to review wether the vehicle system was satisfied with the dynamic performance requirements during the design procedure. But It should be applied the results of the parts test for suspension elements in order to compare between the results of computation and real test. Using VAMPIRE Program made by AEA Technology in UK. the new model also was modified. This paper shows that the static wheel loads calculated from new model is similar to test results. For test on high speed line, we prepared the test devices for evaluating the dynamic performances. which was consisted of the accelerometers( based on Kisler Co.) and the data aquisition systems (based on National instrument Co.), and test program coded by LabView 6i program. These lest devices and programs are flexible to extension the channels for adding sensors and connect to the ethernet network. The acceleration of car bodies, bogie frames and axle boxes were compared between the results of computation and test at 150km/. This paper shows that the results of test were high in high frequency band range but similar frequency band range. It might be considered that these differences were caused by the test which did not performed at constant speed for comparison analysis. Also. It will be able to understand the differences and make better results through a lot of tests planed in future.

본 연구에서는 시설환경, 장서, 서비스, 도서관홈페이지 등에 대한 만족도를 한국사회과학데이터연구원에서 제공하는 KSDC 프로그램을 사용하여, P대학도서관을 이용하는 대학생을 대상으로 2017년 12월 회수한 설문지를 분석하였다. 학생들의 성별, 학년, 전공에 따라 어떤 차이를 보이는지 ANOVA 등의 방법을 사용하여 검정하였고, 설문문항 내 변인간 상관관계의 정도를 Pearson 상관계수를 통하여 검정하였다. 연구결과를 요약하면, (1) 남녀의 성별 분석에서 설문조사 참여율도 여학생이 높고, 만족도도 여학생이 높게 나타난 것을 볼 때 남자대학생들을 도서관으로 유인할 수 있는 정책개발이 필요하다. (2) 그룹별 만족도에서 자료이용 부분이 가장 높게 나타났고, 시설환경 부분이 가장 낮게 나타났다. 특히 평균분석에서도 지리적 접근성이 가장 낮게 나타났으므로 이용자 접근성을 높일 수 있는 특별 대책이 필요하다. (3) 또한 상관관계 분석에서 이용자서비스 그룹과 시설환경 그룹이 높은 상관관계가 있는 것으로 나타났으므로 이용자서비스를 계획할 때 반드시 시설환경 부분을 함께 고려할 필요가 있는 것으로 보인다. 이외에도 이용자가 건의한 의견을 분석한 발전방안도 제시되어있다.
