The present review focuses on the effects of energy intake on performance, changes in body tissue during lactation, and metabolic parameters in dairy cows. Especially, pre-partum nutrition and its influence on lactation are emphasized. In recent decades the increase in genetic potential of dairy cows has increased milk yield. This fact sharpens the problem of a negative energy balance in early lactation because the amount of energy required for maintenance and milk production exceeds the amount of energy cows can consume. Around parturition, reduced feed intake reinforces the situation. Continuing negative energy balance causes decreasing milk yield, fertility problems, and incidence of metabolic diseases. Hence, the cow has to rely on body reserves that were stored in late lactation and the dry period. It is evident that the nutritional status pre-partum acts as the key factor for milk yield and fertility parameters in the following lactation. Cows overfed during the foregoing gestation and which have gained large quantities of body fat have lower dry matter intake along with the need to mobilize larger quantities of body reserves in lactation. The milk yield in the following lactation is lower than in cows fed according to their requirements. Cows restrictively fed in late gestation have a higher feed intake in lactation and a lower mobilization of body reserves. The effect of energy intake post-partum plays only a minor role for performance parameters in lactation. Lipid mobilized from body reserves makes a substantial contribution to the energetic cost of milk production in early lactation and adipose tissue undergoes specific metabolic alterations. Adipose tissue is degraded to free fatty acids, which are used in liver for energy purposes. High lipid mobilisation promotes the development of a fatty liver and therefore a reduced gluconeogenesis.

이 논문의 목적은 지각의 본성에 대한 알바 노에의 행화이론(enactive theory)의 내용과 의의 그리고 문제점을 검토하는 데 있다. 다음 세 가지 이슈들을 중심으로 논의를 진행한다. (i) 과연 몸이 마음의 형성에 아주 특별한 기여를 한다고 볼 수 있는가? (ii) 노에가 두뇌중심주의에 대한 유효한 반대 증거들을 제시하고 있는가? (iii) 노에의 이론이 외적 대상들의 지각을 만족스럽게 설명하는가? 논문의 2장과 3장에서는 각각 (i)과 (ii)에 초점을 두고 노에의 이론에 대해 제기될 수 있는 비판을 다룰 것이다. 그런데 이러한 비판들은 결국 체화된 인지 일반에 대해 제기될 수 있는 비판들이다. 즉, 딱히 노에 이론에 국한된 문제점이라고 할 수 없다. 노에 이론의 특징과 핵심적인 의의를 드러내기 위해서는 (iii)에서 제기된 "지각 현존의 문제(the problem of perceptual presence)"에 주목할 필요가 있다. 이 문제에 대한 노에의 설명이 정확히 어디에 문제점이 있는 지를 밝히는 것이 4장의 목적이다.

최근 의학계에서 건강을 위해 무엇보다 인간의 영성이 중요함을 알고, WHO에서 건강의 정의에서도 "몸과 마음과 사회적 관계적 건강에다 영성을 포함시켰다. 하지만 영성의 중요성은 잘 알아도 막상 영성이 무엇인지 규명하기가 어려운 것이고, 심리학계에서 조차 아직 마음의 문제에서 영성이 무엇인지 정확히 선을 긋지 못하고 있는 입장이다. 본 연구는 영성의 고전적 이론에서부터 최근의 이론을 생물학적 입장과 심리학적 입장의 문헌을 고찰하면서 영성의 특성을 밝혔다. 특히 영성은 오랜 세월동안 각 종교에서 특징적으로 발전되어 왔는데, 최근 의학계에서 실제적으로 불교의 영성으로 'MBSR'과 기독교의 영성으로 'Breakout Principle'을 의료에 접목시키고 있다. 그래서 이러한 영성이 어떻게 심리치료에 긍정적 기여를 하고 있는지 문헌고찰중심으로 밝혀보았다.

In this study, seven models with distinctly different body types were researched and explanatory variables were reviewed. Review was done by using body measurements and the measurements of the appropriate bodice patterns in 1D, 2D, and 3D measurement methods in order to review the pattern making system and the equations for calculating the dimensions of the sleeve caps, which are readily available. Data on human bodies, which can be the criteria for each body part required for the new system for making sleeve cap part, were selected considering conditions such as items with a significantly high contribution rate from the results of regression analysis and the easiness of measurement. As a result of research, an explanatory variable required for the system for making sleeve caps with high general use was extracted. All items with the exception of the waist circumference and upper arm circumference were about the measurement of the form of human bodies, which were newly set in this study. As a result of this study, the equations for calculating the dimensions of each part of the sleeve caps showed distinct differences in comparison to the conventional system of construction.

This paper presents an optimal design process using beads on a body panel to improve interior noise of a passenger vehicle. Except modification of structural members, it is difficult to find effective countermeasures that can work for the intermediate frequency range from 100 Hz to 300 Hz which lies between the booming and low medium frequency. In this study, it is a major goal to find additional counter-measures for this intermediate frequency range by performing optimal design of beads on body panels. The proposed method for design optimization consists of 4 sub-steps, that is, a) problem definition, b) cause analysis, c) countermeasure development and d) validation. The objective function is minimization of interior noise level. The major design variables are the geometrical shape of a bead and combination of beads on the critical panels. Sensitivity analysis and optimization are performed according to the predefined process for an optimal design. It is verified that the proposed design decreases the level of noise transfer function above 5 dB.

Despite the rapid expansion of social security coverage in the 1990s, many wage earners in Korea, especially the majority of the nonstandard workforce are excluded in the social insurance programs. In this regards, the purpose of this paper is to analyze causes of the exclusion of nonstandard workers to the social insurance scheme and to suggest the feasible policy options. Through this paper, four arguments are addressed as follows. First, the main issue for exclusion from coverage of those workers is that they have no entitlement to social insurance. This is not an issue of that they fall below hours or income thresholds for the entitlement Second, the top-down process of the extension in the Korean social insurances have divided the wage earners into two groups, the insider (the included) and the outsider (the excluded). Many nonstandard workers belong to the latter category. Third, the social insurance systems have been designed for the regular workers who were characterized by a full-time with some degree of stability. Reform designed to cope with the growth of nonstandard workers must build on the existing structure of social insurance. Finally, the governance capacity by social security administration body must be improved in order to provide a basic social protection for those workers. For that, four separated social insurance administration bodies could be unified to one administrative body, or tax and contribution of social insurance could be collected by one integrated administration body, the National Tax Service.

This study stems from the work of Lehman et al. (Ergonomics, 2001) which concluded that standing yields better work performance, and from the growing health trend of recommending the reduction of the amount of time spent in sitting (Owen et al., Exercise and Sport Science Reviews, 2010). Lajoie et al. (Experimental Brain Research, 1993) provided an initial significant contribution to a theory that standing requires a person to control balance, equating to demand higher productive output from the cognitive system than when a person is sitting. An assumption was formulated that standing position during class is feasible and can be adopted on the belief that it might contribute positive results to students' performance. The purpose of this study is to identify whether a body position during exams tested along with exposure durations has a significant effect on college students' performance. Mathematical analysis and reading comprehension exam was used to measure the cognitive performance of the students. Two factors, position and duration, were tested for significance with two levels each subjected to six replicates. Twenty-four students from the College of Engineering and Agro-Industrial Technology, University of the Philippines Los Ba$\tilde{n}$os were randomly selected. The experiment showed that the body position during exams is a significant factor for the Math exam, but insignificant for the Reading Comprehension exam.

The aim of this study was to determine the extent to which sociodemographic and health related life-style variables explain body weight distribution and to understand weight contol behavior. To study this study 298 students were selected, it was consisted of obesity group(101) and control group(197). The average age of subjects was 14.2 and the prevalence of obesity was 2-3 per class as 5.6% among 1,793. 71% among same subject was showed higher weight pattern than last one year, ovesity group which was obesity both in 93 and 94 was 34%. Correlation between body weight(under weight/obesity) and independent variables including sociodemographic factor and health- related life style tested through Multiple Classification Analysis was very significant, explained 36% of the total variance. Sociodemografic and hereditary factors such as education level, age of father and physical features of parents, life style factors as exercise preference and perceived health status showed highly contribution to body weight. Concretely, there were showed a higher obesity prevalence tendency when education level and age of father was high, physical features of parents was obesity. In otherwise, there were showed a higher underweight prevalence tendency when education level and age of father was low. Experience rates of weight control was 53% generally, 84% in obesity group, and 11% in underweight group. There were utilized weight control behaviors through diet method mainly in obesity group, diet and exercise methods in underweight group. There were showed that underweight group are prefer exercise to obesity group. Conclusionally, These findings suggest that education, age, physical features of parents, exercise preference and perceived health status is important factors related to body weight among middle school girls. Therefore, there will be considered as valuable factors when we practice health education and consultation related to body weight. Furthermore it is necessary to provide of various informations about weight control and to develop systematic weight control program.
