넙치(Paralichthys olivaceus)는 1980년대 초부터 일본으로부터 수정란을 도입하여 양식되기 시작하였으며, 현재 우리 나라의 주요 해산 양식 대상종이다. 그러나 우리 나라에서 양식되고 있는 넙치는 대부분 일본산일 것으로 추정되고 있으며, 남해안의 경우 자연집단에 심각한 유전자 오염이 이루어져 남해안 고유계통은 찾아보기 어려운 실정이다(박 등, 1996a&b). (중략)

Objective : The purpose of this study is to provide basic information for professional education by investigating to learning styles and achievement goal of the first year students in the department of occupational therapy and physical therapy. Methods : 123 first year students of the department of occupational therapy and physical therapy filled out a questionnaire in Gyeongbuk and Kangwon Province. In this study, Kolb's Learning Styles and Elliot & Church's Achievement Goal were used, and to analyze, Pearson correlation, chi-square were used. Results : The results of the study were as follows. 'Accommodator' was the preferred learning type for students, while 'diverger' was not. Collage students differed from university students in learning styles. A mastery level was the preference in the academic goal types of the students. Male students received higher grades on performance approach goals than female and student of department of physical therapy received higher grades on performance avoidance goals than students in the department of occupational therapy. There is a coefficient of correlation between performance avoidance goal and converger learning type. Therefore, first year students in the department of occupational therapy were not differed from the department of physical therapy in academic achievement but collage students differed from university students in learning styles. Conclusion : From these results, we suggested some effective teaching/learning methods based on the mastery achievement goal. An educational approach is necessary for understanding of the students' individual learning styles and achievement goal characteristics are account for students' individual negative/positive characteristics.

The cultivation of akoya pearls was carried out with bio bead nucleus prepared using the hydroxyapatite. The akoya pearls cultured with bio bead nucleus were shown the color of cream. The luster and orient effect created by an action of the light from nacre were magnificent. The result of XRD is found that the nacre is a calcium carbonate of aragonite form. From the result of SEM, it is found that layers of calcium carbonate and conchiolin are stratified. The properties of akoya pearls cultured with bio bead nucleus are same those of akoya pearl cultivated with bead nucleus made from washboard shell. Because of the bio bead nucleus developed in this study has such a high capacity in producing various sizes and shapes, it is very advantageous for the cultivation of akoya pearls.

Analyses of UV-Vis spectrum and reflectance are useful tools to identify pearls of which color was naturally made or chemically changed. Contents of some trace elements of pearls by using ED-XRF may give us the information that the pearls were originated from marine shells or freshwater shells, and may give us whether the pearls were chemically treated or not. Three types of chemically untreated pearls, freshwater cultured, Akoya cultured and Tahitian cultured, were treated with silver nitrate. UV-Vis absorbance spectrum of Ag was changed after treatment, and reflectance of pearls was decreased. Absorbance of natural black colored Tahitian cultured pearls at 400, 500 and 700 nm was observed. Natural black colored freshwater cultured pearls showed two characteristic absorption patterns in UV-Vis spectra at 380-400, 480-500 nm. Unlike naturally black colored Tahitian cultured pearls, the absorption spectrum at 700 nm could not be found from black freshwater cultured pearls. Manganese was not detected in the pearls from marine shells, and strontium content of the pearls from marine cultured shells was higher than that from freshwater cultured shells. According to ED-XRF analysis, Ag contents of silver nitrate treated pearls increased as more time passed, because silver ion invaded to nacre layer of the pearls. Since Ag content of the black pearls known as untreated ranged under 0.1%, analysis of Ag content may used to distinguish the black pearls are treated or not in marketplace.

The purpose of this study is to analyze the factors of the main selection criteria of the contract form used to conclude the sales contracts of used ships and to assist parties in selecting the most suitable contract form for trading situations. The methods of the study are based on identifying the factors from the questionnaires using analytic hierarchy process analysis, following the selection of typical details through interviews with the S&P Broker Group and finding the solutions that match each detail. The analysis shows that ship traders prefer the Norwegian Sales Form (NSF) to NIPPONSALE for various reasons. Considering the sellers' situations, NFS is the more reasonable option for major countries, except Japan. NIPPONSALE is relatively more focused on the advantages of the buyer's conditions, including for Japan. It is important to select the appropriate clauses from these types of contract, according to the trading conditions, including the main and additional terms, in order to create a mutual agreement between the shipper and the consignee that leads to more cooperation and balances the purposes of both parties in adjusting the time for securing and disposing of the vessels.

This study was conducted to determine how analytic-holistic thinking style, one of the cultural characteristics, affects intentionality judgment and what role the crime typicality plays in the process. To this end, the psychological mechanism of intentionality judgment was confirmed in cases where the criminal typicality was manipulated by the moral characteristics of the crime perpetrator and victim. As a result, higher the criminal typicality lead to higher intentionality judgement. In addition, it was found that people with relatively holistic thinking style (with high causality and perception of change) judge less of the perpetrator intentionality. In particular, it was confirmed that the analytic-holistic thinking style interacts with criminal typicality and affects the intentionality judgment. Specifically, people with a holistic thinking style (high causality) judged the perpetrator to have high intentionality in typical cases, but judged in a reverse way in atypical cases. It means that, holistic thinkers, compared to analytic thinkers, strongly judge intentionality based on criminal typicality considering the moral characteristics of not only the perpetrators but also the victims. Along with the significance of this study, the relationships among analytic-holistic thinking style, criminal typicality and intentionality judgment were discussed.

Mathematical modeling can be described as a series of processes in which real-world problem situations are understood, interpreted using mathematical methods, and solved based on mathematical models. The effectiveness of mathematics instruction using mathematical modeling has been demonstrated through prior research. This study aims to explore insights for mathematical modeling instruction by analyzing the metacognitive characteristics shown in the mathematical modeling cycle, according to the mathematical thinking styles of elementary math gifted students. To achieve this, a mathematical thinking style assessment was conducted with 39 elementary math gifted students from University-affiliated Science Gifted Education Center, and based on the assessment results, they were classified into visual, analytical, and mixed groups. The metacognition manifested during the process of mathematical modeling for each group was analyzed. The analysis results revealed that metacognitive elements varied depending on the phases of modeling cycle and their mathematical thinking styles. Based on these findings, didactical implications for mathematical modeling instruction were derived.

Individual consumer characteristics change as the individual lifestyle changes. Each individual's unique lifestyle influences substantially the individual consumer behavior. Individual consumer's behavioral pattern varies significantly depending on the individual consumer's use of credit cards. Each individual's lifestyle or individual's perception of credit cards' brands and perceptual difference in qualities of credit cards' brands influence the individual's credit card selection. Credit card companies have been doing several researches in analyzing credit card users' lifestyle characteristics and consumer behavioral characteristics. However, researches on the relation of model structure among variables such as individual lifestyle, credit cards brand, quality perception of credit cards and credit card selection are not quite noticeable. Therefore, in this research we aim at providing a theoretical foundation with credit card companies by analyzing the relation of model structure among these factors.

Lifestyle has the largest influence on purchasing intention. Currently, consumers have to be adjusted to dynamic environmental change, therefore they are demanding more and more on bakery items and functional food products. It is important to understand the trend of customers' eating habits and the effect of this trend on purchasing intention as well as the development of special characteristics in purchase, viewpoints, and behaviors. Based on this fact, this study was conducted to classify the types of lifestyle according to the consumer's behavior and to examine how the variety and quality of bakery products affect consumer's purchasing pattern. The subjects of this survey were housewives in thirties and forties at the national capital region. AIO(activities, interests, opinions) analysis was used to classify lifestyle and to investigate the effect or relationship between lifestyle, variety and quality of bakery products. Lifestyle was classified into the pursuit of rationality, the pursuit of utility and the pursuit of convenience. The information was the most concerning area in the pursuit of rationality, the taste in the pursuit of utility, and convenience in the pursuit of convenience. The purchasing intention was not affected by the quality of the bakery product itself but by the satisfaction with the service of the bakery.
