  • The purpose of this study is to determine the effects of the aerobic exercise type on macronutrient self-selection. Male Sprague-Dawley rats were placed on a macronutrient self-selection diet for 4 weeks. For this purpose, mixed feeds were prescribed for the rats while they were forced to swim and run for 4 weeks. Animals were either swimming exercise or treadmill running exercised at 20m/min(60min/day). Cumulative daily energy and macronutrient intake were determined during this period. The running exercise group gained weight much more than the control group, while the swimming exercise group lost weight less than the control group. Such findings suggests that the former group took more feed. On the other hand, the dietary efficiency of the control group was higher, which implies that no physical exercise would result in a higher dietary efficiency. And there was significant difference of total dietary and calorie intakes among the three groups, Although insignificant in statistical means, it was found that the running group took feed most, which is attributable to the homeostasis requiring the supplementation of the calorie lost by exercise. Also, the running exercise group took the protein and carbohydrate most. while the control group took fat most. The decrease of fat intake by the running exercise group suggests the possibility that the in-body enzymes should adapt themselves to the changing in-body condition caused by the endurance exercise. In contrast, it is conceived that the more intake of the carbohydrate may be attributable to the need of supplementing the nutrient lost by the endurance exercise. As discussed above, the endurance exercise group took carbohydrate and protein and less fat than control group. In particular, it was found that the amount of feed intakes was affected much by types, intensity and duration of the exercises. All in all, such findings would apply to human beings. Now can increase the intakes of carbohydrate and decrease the intake of fat through an effective running exercise program and thereby, change our dietary patterns to the benefit of our body and simultaneously, prevent and adult\\`s diseases by decreasing the in % body fat level.(Korean J Nutrition 33(8) : 794-801, 2000)

  • This study was conducted to investigate the effects of health lifestyle on high protein snack selection attributes and purchase behaviors among individuals aged 20-30 with high protein snack intake. In addition, the relationship between perception, attitude, satisfaction and recommendation of high protein snacks was invested. Finally, this study aims to provide basic information for marketing high-protein snacks and customized high protein snacks. Analysis of the selection attributes most important for healthy lifestyle, revealed significant differences among all groups excluding the external seeking group (p<0.001). The free living group regarded trust as one of the most important attributes of high protein snack selection, and both the tempered control group and the low-interest group found sensation and price factor to be important. Therefore, when developing high-protein snacks, it is important to determine which attributes of the snack will be highlighted by segmenting the consumer into health lifestyles. Focusing on what ingredients are used to develop high-protein snacks and nutritional ingredients is also important when targeting a free lifestyle group as the main customer. In addition, developing snacks that do not offer depending on the protein content is important when targeting a temperate management group or a low-interest group.

  • 본 연구는 주로 의사결정과제를 통해 검증되어왔던 무작위적 리더 선출 방법의 우수성을 실제 수행과제로 확장시켰고, 리더 선출 방법과 집단 효능감의 집단수행에 대한 상호작용효과를 살펴보았다. 2(리더 선출 방법: 공식적/무작위적) × 2(집단 효능감: 저/고) 피험자간 실험설계를 통해 집단수행에 대한 영향을 검증했다. 연구 결과, 리더 선출 방법의 주효과가 유의하여 공식적으로 리더가 선출된 집단보다 리더가 무작위적으로 선출된 집단의 수행이 유의하게 높았다. 또한, 두 변인 간의 상호작용이 유의하였는데, 집단 효능감이 낮을 때는 리더가 공식적으로 선출된 집단과 무작위적으로 선출된 집단 간의 수행차이가 유의하지 않았으나, 집단 효능감이 높을 때는 리더가 공식적으로 선출된 집단보다 무작위적으로 선출된 집단의 수행이 유의하게 높았다. 본 연구의 결과는 높은 집단 효능감이 집단의 수행에 긍정적인 영향을 주기 위해서는 리더가 집단의 사회정체성을 손상시키지 않는 방법(예. 리더와 구성원의 차이점을 부각시키기 보다는 동질성에 대한 지각을 높이는 방식)으로 선출되어야 한다는 점을 제안함으로써 조직과 작업 현장에 기여할 수 있다. 향후에 본 연구를 작업 팀으로 확장하여 연구할 필요성을 논의하였다.

  • This study aimed to analyze beverage usage motives according to selection attributes of beverage shops. Questionnaires were completed by 509 persons living in the Seoul, Gyeonggido area. The results show significant differences by gender, age, and monthly income. Female customers stayed longer and spent more money than males. Younger customers (20's, 30's) stayed longer and visited beverage shops to meet friends. Those with higher incomes stayed shorter and visited beverage shop with company staff. In the factor analysis of selection attributes of beverage shops, there were four factors: 'physical environment', 'economic benefit', 'specialized service', and 'approach convenience'. Two clusters, derived from selected attributes of beverage shops, were 'highly involved group' and 'low involved group'. The 'highly involved group' was high income and highly educated, whereas the 'low involved group' was low income and low educated. 'The highly involved group' drank beverages in the office and school while the 'low involved group' drank beverages at home. The 'highly involved group' cited safety, comfort, pleasure, and happiness more than the 'low involved group' at beverage shops. Beverage shops should develop health beverages such as caffeine or sugar-controlled beverage for 'the highly involved group'. Discounts for take-out beverages and promotional coupons should be used for the 'low involved group'.

  • The location selection of virtual machines in distributed cloud is difficult because of the physical resource distribution, allocation of multi-dimensional resources, and resource unit cost. In this study, we propose a multi-object virtual machine location selection algorithm (MOVMLSA) based on group information, doubly linked list structure and genetic algorithm. On the basis of the collaboration of multi-dimensional resources, a fitness function is designed using fuzzy logic control parameters, which can be used to optimize search space solutions. In the location selection process, an orderly information code based on group and resource information can be generated by adopting the memory mechanism of biological immune systems. This approach, along with the dominant elite strategy, enables the updating of the population. The tournament selection method is used to optimize the operator mechanisms of the single-point crossover and X-point mutation during the population selection. Such a method can be used to obtain an optimal solution for the rapid location selection of virtual machines. Experimental results show that the proposed algorithm is effective in reducing the number of used physical machines and in improving the resource utilization of physical machines. The algorithm improves the utilization degree of multi-dimensional resource synergy and reduces the comprehensive unit cost of resources.

  • Identifying the selection criteria of wedding planners, who are the main human resource that contribute to the overall satisfaction level of a wedding's preparation, can produce important data for the wedding industry as it faces a transition period. To develop a scale for wedding planner selection criteria, preliminary items were prepared based on in-depth interviews with an experienced wedding planner group and a comprehensive review of previous studies, such as studies on selection criteria in the wedding industry and service work similar to wedding planners and wedding planner selection criteria. The preliminary items were tested for content validity using a focus group interview, comprising people in the wedding industry, and were refined accordingly. Then, the definitive quantitative questionnaire items were developed after conducting a preliminary survey. The main survey for this study was conducted using the responses of 295 consumers taking an Internet questionnaire. Exploratory factor analysis, Cronbach's alpha, and confirmatory factor analysis were adopted to develop the scale, which was tested for convergent validity and discriminant validity. This study is academically significant in that it developed a selection criteria scale tailored to wedding planners to address an area that has not been covered in previous studies. It is recommended that future studies conduct empirical analyses using the selection criteria developed in this study to compare influential variables that could affect behavior intention.
