A fur has emerged as one of fashion staples. there has been a rising interest in fur industry. Therefore, this study investigated how to estimate the amount of raw materials consumed at the production of fur clothes, and the scope of the study was limited to mink clothes. For an empirical study, in addition, Koreans' favorable mink design was chosen based on previous studies and sales of fur clothes, and its consumption was estimated. The consumption of mink clothes depends on the special feature of natural resources such as place of origin, gender and variety. Therefore the method of consumption for mink clothes is inevitably different from it of fiber clothes. Considering the procedure of mink clothe's production as collect same kind of a fur and process though pattern placement, first is outfut work for consumption. At estimation of the consumption of mink clothes, the number of minks was counted by matching the area of mink skin with that of the mink cloth patterns. Then, the usable area of the patterns was calculated after splitting them into diverse figures such as triangle, quadrangle and trapezoid. If we divide area by using the similar in shape of pattern and calculate, We can find high efficiency by reducing extra space. Specially we can expect more efficient work system when we use computers for efficient division of area.

Despite the abundance of research on alcoholic-beverage consumption in the food and beverage marketing literature, research directly assessing and comparing consumers' psychological motives for drinking different types of alcoholic beverages is relatively limited. There is also a paucity of research comparing drink-type specific consumption motivations in an Asian market. Paying attention to some recent new changes in the alcoholic-beverages market of South Korea, this study investigated South Korean young adult female consumers' alcoholic-beverage type-specific drinking motives. A self-administered online survey of 340 young adult female drinkers about their alcohol-consumption patterns, alcoholic-drink preferences, involvement with alcohol, and four types of drinking motives (coping, social, conformity, and enhancement motives) revealed differences in: (1) the association between the consumer's alcohol involvement level, alcohol consumption frequency/amount, and preferences for alcoholic beverages across different types of alcoholic drinks; (2) the underlying psychological motives for drinking different types of alcoholic beverages; (3) the association between consumption contexts and alcoholic drink types; and (4) the consumption patterns and drinking motives across different consumer groups that are segmented in terms of their most preferred type of alcoholic beverages. These findings point to the importance of investigating drink-type-specific consumption motivations in alcoholic-beverage consumption research. Limitations and implications for future research are also discussed.

Objectives: The purpose of this study was to investigate the association between suicidal behavior and patterns of alcohol consumption in Korean adults. Methods: This study was based on data provided by the Korea National Health and Nutritional Examination Survey from 2007 to 2011. A total of 42 347 subjects were included in the study, of whom 19 292 were male and 23 055 were female. Logistic regression analysis was performed to assess the association between patterns of alcohol consumption and suicidal behavior. Results: Among the study subjects, 1426 males (11.3%) and 3599 females (21.2%) had experienced suicidal ideation, and 106 males (0.8%) and 190 females (1.1%) had attempted suicide during the previous 12 months. Alcohol Use Disorders Identification Test (AU-DIT) scores were found to be associated with suicidal ideation in males and associated with both suicidal ideation and suicide attempts in females. Alcoholic blackouts were associated with suicidal ideation and suicide attempts in males, and were also associated with suicidal ideation in females. Conclusions: In this study, we found that certain patterns of alcohol consumption were associated with suicidal behaviors. In particular, only alcoholic blackouts and categorized AUDIT scores were found to be associated with suicidal behavior in males. We therefore suggest that further research is needed to examine this relationship prospectively and in other settings.

Unlike studies of Europeans and Americans, many epidemiological studies of the Korean population have indicated that their risk for cardiovascular disease does not decrease with a vegetable-rich diet. The different dietary practices of Koreans, who consume salted vegetables instead of fresh vegetables (common in the Western diet), has been suggested as a reason for this observation. Korea is in a period of rapid epidemiologic transition, which includes dietary and disease patterns; therefore, this study investigated differences in the food consumption pattern and blood lipid profiles of Koreans compared to Europeans and Americans. The identification of dietary patterns related to blood lipid abnormalities was carried out using the 2007~2009 Korean National Health and Nutrition Survey data from 14,056 subjects. Dietary patterns were analyzed according to food group and nutrient intake. Blood lipid abnormalities were classified into three groups: hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterolemia (hypo-HDL-cholesterolemia). The prevalence of hypercholesterolemia, hypertriglyceridemia, and hypo-HDL-cholesterolemia was 12.4%, 16.2%, and 27.7% respectively. In our analysis, the low consumption of all food groups was related to hypercholesterolemia. The high consumption of vegetable-containing foods, alcoholic beverages, and the low consumption of milk products were associated with hypertriglyceridemia and hypo-HDL-cholesterolemia. Thus, unlike Europeans and Americans, the low consumption of all food groups is related to hypercholesterolemia and a low consumption of milk products is related to hypertriglyceridemia and hypo-HDL-cholesterolemia. Dietary pattern might play a role in epidemiologic transition of Korean. Also, this study implies necessity of further research using longitudinal data.

This exploratory study examines the critical factors associated with news consumers' perception of information overload and news consumption patterns. An online survey was conducted with Qualtrics panels (N = 1001). The demographics and three antecedent factors of perceived information overload were considered including the frequency of news access through multiple media platforms, level of attention to news, and interest in news. Three news consumption patterns were investigated as possible consequences of perceived information overload: news avoidance, selective exposure, and willingness to pay for news. The results of hierarchical regression analyses revealed a meaningful distinction between general and news information overload. Overall, news consumers who paid more attention to news through newer media/platforms/devices perceived higher levels of information overload, were more willing to pay for the news, and often avoided news or selectively exposed themselves to certain sources of news to manage news information overload.

Robot engineering is developed mainly in the field of intelligibility such as a manipulation. Considering the popularization of robots in the future, however, a robot should be studied from a viewpoint of saving energy because a robot is a kind of machine with a energy conversion. This paper deals with minimizing an energy consumption of a manipulator which is driven in a point-to-point control method. When a manipulator carries a heavy payload toward gravitation or the links are de-accelerated for positioning, the motors at joints generate electric energy. Since this energy can be regenerated to the source by using a chopper, the energy consumption of a manipulator is only heat loss by an electric and a frictional resistance of the motors. The minimization of the sum of these losses is reduced Lo a two-points boundary-value problem of an non-linear differential equation. The solutions are obtained by the generalized Newton-Raphson method in this paper. The energy consumption due to the optimum angular velocity patterns of two joints of a two-links manipulator is compared with conventional velocity patterns such as quadratic and trapezoid.

The purpose of this study is to analyze consumption expenditure patterns over family life cycle. The data used in the study is the 1994 Survey data from Annual Report on the Family Income and Expenditure Survey. The study sample included 26,980 salary and wage earners’ households living in cities. The family life cycle was classified into six stages and items of expenditure were classified into 12 categories. Frequency distribution, mean, one-way ANOVA, Scheff test, and regression analysis were used to analyze the data. The major findings of this study are as follows : First, the average consumption propensity differs among family life cycle. Second, the amount and budget share of consumption expenditure for each expenditure category differ significantly among family life cycle in all expenditure categories. Third, family life cycle is found to be a significant factor on expenditure of food and education, and also on budget share of education.
