This study was designed to estimate the improvement of Validity for food frequency questionnaire(FFQ) by offering multiple choice portion size in developing a questionnaire. Validity of the two methods(food frequency questionnaire I=FFQ I & Food frequency questionnaire II=FFQ II) was tested in comparison with reference method of the 7-day weighed record(7DWR). Dietary consumption data of the three methods(FFQ I, FFQ II & 7DWR) were collected from 101 female university students for the analysis. Validity was measured in two categories : One was the nutrient intake value from the three methods, the other was the identification of between individual variation within the group. Spearman's rank order correlation test and distribution graphs were used for the analysis. The result showed that individual intake value of the FFQII was closer to that of the 7DWR than that of the FFQ I.Spearman's rank order correlation between the FFQII and the 7DWR did not show any improved correlation. The distribution graphs of nutrient intake derived from both the FFQ I and the FFQII were different from that of the 7DWR. Therefore, it could be suggested that single one portion size food frequency questionnaire is an equally efficient method as a multiple choice food frequency questionnaire to be adopted in epidemiologic studies.

Currently, Korea is on the verge of entering into an ultra-aged society and the associated market size is growing. In this regard, customer-centered design that understands the consumer needs of the new silver generation, which is emerging as a new consumer group, and reflects them in products is the key to the success of the high-value-added fashion industry. Therefore, this study reviewed the changes in physical, biological, social, and psychological characteristics of the new silver generation, through a review of related books and previous studies, and secured the direction for clothing product development for the new silver generation. The literature review was supplemented by group interviews to accurately identify the needs of silver consumers. In addition, the study conducted case analysis through web searches of fashion magazines, newspaper articles, brand web sites, and trend information sites to investigate the market trends of one-mile wear products that have emerged due to the COVID-19 pandemic, the characteristics of one-mile wear brands, and products for new silver women, including size specification analysis and sewing techniques that minimize skin irritation while reflecting the consumer's characteristics. Based on the results of this study, a competitive design and product development were proposed from an economic and industrial perspective that can enhance the product value and maximize the marketing effect by developing consumer-oriented one-mile comfort wear products with aesthetic, practical, functional, and economic values that satisfy the characteristics and needs of new silver women.

In an early paper Skumanich suggested the existence of a scaling law relating the mean sunspot magnetic field with the square-root of the photospheric pressure. This was derived from an analysis of a variety of theoretical spot models including those by Yun (1968). These were based on the Schliiter-Temesvary (S- T) similarity assumption. To answer criticisms that such modeling may have unphysical (non-axial maxima) solutions, the S-T model was revisited, Moon et al. (1998), with an improved vector potential function. We consider here the consequences of this work for the scaling relation. We show that by dimensionalizing the lateral force balance equation for the S- T model one finds that a single parameter enters as a characteristic value of the solution. This parameter yields Skumanich's scaling directly. Using an observed universal flux-radius relation for dark solar magnetic features (spots and pores) for comparison, we find good to fair agreement with Yun's characteristic value, however the Moon et al. values deviate significantly.

According as the importance of brand value has increased, it's so significant that we analysis brand loyalty and buying-behavior types in the side of various consumption. Also, it will make it for us to presuppose consumer's buying-behaviors in modem society. As an analytical result of consumer's buying-behavior type, they were divided into four type; price value consciousness type, sale orientation type, price-quality schema type, convenience type. As a result of cluster analysis and one-way ANOVA on the three type of consumer's buying-behavior : Price-orientation type, high quality orientation, convience orientation. And it was found that there was relation between buying-behavior types and brand loyalty. Specially, it was high positive relationship between high quality orientation and brand loyalty, convience orientation and brand loyalty.

Convective heat transfer in a two-dimensional horizontal and vertical channel with isothermal rectangular beams attached to one adiabatic wall is investigated from the numerical solution of Navier-Stokes and energy equations. The solutions have been obtained for dimensionless beam spacings, S/L=1~4, aspect ratios of beam, H/B=0.25~4, Reynolds numbers, Re=50~1000 and Grashof numbers, $Gr=0{\sim}5{\times}10^4$. The total mean Nusselt number, Nu_T for horizontal and vertical channels shows same value at Gr=0. As Gr increases, Nu_T for horizontal channel increases, but Nu_T for vertical channel shows similar value at S/L=2, H/B=0.25, Re=100. The total mean Nusselt number for horizontal channel is higher than that for vertical channel. As H/B increases, $Nu_T$ for both channel decrease at $Gr=10^4$, Re=100.

엔터테인먼트산업의 OSMU(One Source Multi Use)의 중심에 있는 영화와 게임, 두 매체간의 OSMU 방법은 스토리공유에서 가장 두드러진다. 특히 게임의 스토리텔링은 서사학적 관점(소설, 영화 등 전통적인 스토리 구조)에서 게임에 활용될 수 있는 요소들과, 게임의 특성인 상호작용성을 반영하는 요소들의 조화에 중점을 두고 있다. 영화의 게임화, 게임의 영화화에 있어 성공적 스토리텔링의 중심요소는 스토리 밸류(Story Value)라 할 수 있을 것이다. 본 논문에서는 조셉 캠벨의 '영웅의 여정' 단계와 그레마스의 행위소 모델이론을 바탕으로 스토리밸류의 대표적인 요소인 스토리 이벤트, 캐릭터유형 및 관계, 캐릭터의 갈등유형의 관점에서 영화의 게임화와 게임의 영화화를 대표하는 사례분석을 통해 두 매체간의 호환 가능한 스토리텔링 및 캐릭터 설정방식을 모색해 보고자 한다.

The hydrochemistry of groundwater from 47 wells in the Chungwon area, Korea was analyzed to examine the occurrence of natural radionuclides like uranium and radon. The range of Electrical Conductivity (EC) value in the study area was $67{\sim}1,404{\mu}S/cm$. In addition to the high EC value, the content of cations and anions also tends to increase. Uranium concentrations ranged from $ND{\sim}178{\mu}g/L$ (median value, $0.8{\mu}g/L$) and radon concentrations ranged from 80~12,900 pCi/L (median value, 1,250 pCi/L). Uranium concentrations in one well, that is 2.8% of the samples, exceeded $30{\mu}g/L$, which is the Maximum Contaminant Level (MCL) proposed by the US Environmental Protection Agency (EPA), based on the chemical toxicity of uranium. Radon concentrations in three wells, that is 6% of the samples, and one well, that is 2.8% of the samples, exceeded 4,000 pCi/L (AMCL of the US EPA) and 8,100 pCi/L (Finland's guideline level), respectively. Concentrations of uranium and radon related to geology of the study area show the highest values in the groundwater of the granite area. The uranium and radon contents in the groundwater were found to be low compared to those of other countries with similar geological settings. It is likely that the measured value was lower than the actual content due to the inflow of shallow groundwater by the lack of casing and grouting.

One of the most important research works in modern business enterpise is the relation between the purpose of business enterprise and decision making behavior of manager. It is because the coincidence of the former and the latter is considered an ideal type in evaluating the result of business management. Here I have set up assumptions in order to solve the above statements: (1) What purpose does the modern business enterprise set up and what kind of economic background does it have? (2) What is the theory of maximization of stock value among the purposes of business enterprise? (3) What kind of decision making do we do in the maximization of stock value in busiess administration? (4) How is the behavior of business financial manager's intention and decision made? The result pursued under the above assumptions shows that business manager's behavior of decision making is affected according to the degree that he gets some information, but basically is determined in consideration of his autonomous standpoint, namely the stability of business enterprise and the stability of manager himself while he faithfully performs his duty which is entrusted by stockholders. Therefore we come to the conclusion that there is a little gap between a manager's behavior of decision-making and the purpose of stock value maximization.

Since the mid 1980s, the concept of logistics has become more important to the enterprises in strategic sense because it had aggrandized itself to more comprehensive and integrative concept. Therefore study on the service organization of the logistics system for customer’s satisfaction from the management’s point has been focused as one of the major subject in order to improve the logistics quality which would ultimately increase the value of logistics service. This study has been focused on what the port logistics functions and the factors of the port logistics quality are those Korean port managers acknowledge as important factor. And examins these port logistics quality levels and the port logistics value (port productivity, service results) obtained by the results of these activities while reviewing the relation of the custom value which the port managers evaluate in order to evaluate and promote the competitiveness of the Korean port. According to the study results the port logistics function which the Pusan Container Terminal managers recognized as important were customer service management the flexibility of the port facilities and curtailment of the original operation cost of the port. It also indicated that the managers recognized the importance of the customer-oriented terminal management as it showed a close relationship with the port quality level.
