In this paper we conduct comparative statics for optimal consumption and portfolio selection of an agent who has a utility function of Epstein and Zin type. We derive the Slutsky equations and decompose the total effects of changes into the substitution effects and the income effects. We identify the role of the elasticity of intertemporal substitution and the coefficient of relative risk aversion.

현 퇴직연금제도는 퇴직후 연금 지급방식에 대한 규정이 없다. 이에 대한 대안으로 연금 선진국에서 보편적으로 적용되고 있는 'Programmed Withdrawal'을 고려할 수 있다. 'Programmed Withdrawal'은 출금액의 산출방법에 따라 대표적으로 정액 방식, 정률 방식, 최종연령 방식 그리고 기대여명 방식으로 구분되며, 각 산출방식에 따라 인출할 수 있는 금액이 달라진다. 따라서 현행 자본시장통합법에 근거하여 가입자의 위험성향에 따른 투자성과를 반영하기 위하여 국내 금융자산의 기대수익률 그리고 제 6회 경험생명표을 적용한 실증분석을 실행하였다. 그 결과, 연령별, 성별로 적합한 자산투자비율이 다소 달랐으며 이로 인해 지급방식별 부족리스크와 상속재원이 달라질 수 있음을 확인할 수 있었다.

This study compares and contrasts the consumer decision-making styles (CDMS) of South Korean and American Generation Y females. A total of 117 American female and 206 Korean female consumers completed self-report survey questionnaires to assess their consumer decision making styles. Exploratory principal components factor analysis using varimax rotation was used to categorize the items into an underlying set of American and Korean decision-making characteristics. Two-tailed independent t-tests were conducted to examine the differences between the two groups when items appeared to have common factors. Factor analysis identified five common factors between the two samples (i.e., enjoyment, shopping aversion, price consciousness, brand consciousness, and quality consciousness). The t-test results report significant differences in the items reported in each factor between American and Korean females. Some of the factors are more indicative of American female Generation Y consumers than Korean female Generation Y consumers. For example, the American female sample seemed to enjoy shopping and prefer brand names more than the female Korean sample. Koreans females seem to have a higher aversion to shopping than Americans; in addition, Koreans females seem to be more accepting of discount and outlet stores, will wait until the price is low before buying a product, and prefer sales when shopping. Based on the findings, the instrument identified varying CDMS between the two samples used. Previous studies using the Sproles and Kendall (1986) instrument experienced the same issue (Bakewell & Mitchell, 2004, 2006; Bauer et al., 2006; Durvasula et al., 1996; Fan & Xiao, 1998; Hanzaee & Aghasibeig, 2008; Mitchell & Walsh, 2004; Siu et al., 2001; Walsh et al., 2001). The results support the idea that no single instrument can be used to examine CDMS in different cultures. This suggests that each country has a CDMS with internal characteristics. Limitations and research for future studies are also discusse.

I investigated the situation of self-realization for oral malodor and real occurrence of it and researched the situation of coincidence by self-administrated questionnaire and real oral malodor of dental hygiene students in Kyeonggi province and Kyeongbuk province to use as a reference data on prevention and treatment of oral malodor. The obtained results were as follows: 1. Concerning the grade of the subjective symptom of oral odor, a little bit oral malodor was the highest by reaching 77.6%, and no oral malodor was 20%. 2. The time when one feels the oral malodor highest was revealed immediately after awakening from the sleep by running up to 88.2%. 3. Concerning the extent of aversion during the occurrence of oral malodor from other people, 57.6% expressed as unpleasant, and 3.5% showed no aversion. 4. Concerning the intention to participate in the prevention program against the oral malodor, 51.8% had intention of it. 5. Hydrogen sulfide 7.61V19.30, methyl mercaptan 9.53V67.90, dimethyl sulfide 58.31V121.37(pF0.05) marked as causing factors in the 132 respondents who answered that they had a little bit oral malodor in comparison with the grade of subjective symptom and the measurement of actual oral malodor. As the above-mentioned results were obtained by limited subjects, the more diversified and precise comparative study is considered to be needed through the classification of various levels of research subjects.

본 연구에서는 소유효과(endowment effect)와 손실회피(loss aversion)성향에 기인한 판매자의 판매용의가격(willing-to-sell price: WTS)과 구매자의 지불용의가격(willing-to-pay price: WTP) 간의 차이에 관한 기존 연구를 최근 점점 더 소비자들이 경험하고 있는 새로운 유통경로인 온라인 경매라는 거래상황에서 재검증하였으며, 동시에 이러한 판매자와 구매자의 용의가격의 차이에 조절적 영향을 주는 요인으로, 이득(gain)과 손실(loss)에 대한 소비자들의 휴리스틱적인 성향과 관련된 기존 연구결과들을 바탕으로 하여, 제품 유형(product type)과 소비자가 가지고 있는 목적 지향성(goal orientation)이라는 추가적인 조절변수들의 효과를 살펴보았다. 실험결과, 기존연구와 마찬가지로 판매자들이 제시하는 용의가격(WTS)이 구매자들이 지불하고자 하는 용의가격(WTP)보다 높았으며, 이 두 가격의 차이는 거래되는 제품이 소비자의 입장에서 실용적인(utilitarian product) 가치를 갖는 제품일 때보다 쾌락적인(hedonic product) 가치를 갖는 제품일 때, 또한 거래에 참여한 소비자가 향상 목적(promotion goal)을 가지고 있을 때보다 예방 목적(prevention goal)을 가지고 있을 때 더욱 두드러지는 것으로 나타났다. 마지막으로, 본 연구결과의 이론적 및 실무적 시사점, 그리고 본 연구의 한계점 및 향후 연구방향에 대해서 논의하였다.

Recently, the u-IT applications for plants and livestock become larger and control of livestock farm environment has been used important in the field of industry. We implemented wireless sensor networks and farm environment automatic control system for applying to the breeding barn environment by calculating the THI index. First, we gathered environmental information like livestock object temperature, heart rate and momentum. And we also collected the farm environment data including temperature, humidity and illuminance for calculating the THI index. Then we provide accurate control action roof open and electric fan in of intelligent farm to keep the best state automatically by using collected data. We believed this technology can improve industrial competitiveness through the u-IT based smart integrated management system introduction for industry aversion and dairy industries labor shortages due to hard work and old ageing.

Feeding is an interaction between a child and caregiver, and feeding difficulty is an umbrella term encompassing all feeding problems, regardless of etiology, severity, or consequences, while feeding disorder refers to an inability or refusal to eat sufficient quantities or variety of food to maintain adequate nutritional status, leading to substantial consequences, including malnutrition, impaired growth, and possible neurocognitive dysfunction. There are 6 representative feeding disorder subtypes in young children: infantile anorexia, sensory food aversion, reciprocity, posttraumatic type, state regulation, and feeding disorders associated with concurrent medical conditions. Most feeding difficulties are nonorganic and without any underlying medical condition, but organic causes should also be excluded from the beginning, through thorough history taking and physical examination, based on red-flag symptoms and signs. Age-appropriate feeding principles may support effective treatment of feeding difficulties in practice, and systematic approaches for feeding difficulties in young children, based on each subtype, may be beneficial.

The purpose of this study was to segment the female college apparel market based on fashion lifestyle and to develop a profile of each segment regard to fashion information sources, clothing benefits sought, and store selection criteria. The data were collected through questionnaire by random sample of 522 female college students. By cluster analysis of lifestyle factors, three groups were identified. (fashion leaders, fashion followers and fashion aversion), Three groups were then compared through multivariate analysis of variance on 11 fashion sources, 10 clothing benefits sought and 90 store selective criteria. Significant difference were found among the three groups on all these variables which indicate that fashion lifestyle can be a useful base for segmenting female apparel market and these groups are unique in terms of fashion information sources, clothing benefits sought and store selective criterias.

해상교통관제사의 업무는 선박교통의 안전과 효율을 목적으로 하는 의사결정의 연속이다. 의사결정은 문제해결과정의 일종으로 가치 판단을 포함한다. 올바른 의사결정을 내리기 위해서는 해상교통상황을 정확히 파악하는 것이 우선되어야 하지만, 상황판단을 제대로 했다하더라도 의사결정을 그르칠 위험이 있다는 측면에서 관제사가 적극적으로 습득하여야 하는 인지과제다. 본고에서는 먼저 관제사에게 필요한 의사결정 이론에 대해서 기술한 뒤, 이를 구체적인 관제과제에 적용할 때 합리적인 의사결정 모델보다는 휴리스틱 또는 재인촉발의사결정 모델을 사용한다는 점을 밝혔다. 또한 관제사의 의사결정 과정에서 발생할 수 있는 실수를 사례 위주로 고찰하였다. 특히 관제사의 업무역량 향상을 위해서 의사결정방법을 어떻게 훈련할 것인가를 제안하였다.
