The present study was designed to test the validity of the semen analysis(S/A) and the sperm penetration assay(SPA) as a prognostic indicator of male fertility in 123 patients undergoing in vitro fertilization(IVF). We attempted to correlate the traditional semen parameters or the extent of sperm penetration in SPA with the results of human IVF rate or cleavage rate. Poor correlation was found between the results of S/A and human IVF rate(sensitivity, 80.6% ;specificity, 46.7%; positive predictive value, 91.6%;negative predictive value, 25%). Conversely, good correlation was found between the results of SPA and human IVF rate(sensitivity, 100% ; specificity, 80% ;positive predictive value, 97.3% ;negative predictive value, 100%). Our results corroborate the conclusion that SPA can be a valuable tool as a prognostic indicator of male fertilizing ability.

This study conducted a online survey (URL), DM, , E-mail, etc. were used to sample 371 people using the standard convenience sampling method, and 320 valid samples excluding 51 unfaithful respondents were analyzed by applying causality (SEM). First, the hypothesis was adopted with the influence of positive (+) on the emotional response of the human brand's goods value. Second, the hypothesis was adopted that emotional response has a positive (+) effect on consumption behavior. Third, the human brand's goods value has a positive (+) effect on consumption behavior, and the hypothesis was partially adopted. Finally, the indirect effect of emotional response in the relationship between goods value and consumption behavior was found to be statistically significant.

The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent ＋ children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.

Human uses sight, tactile sense to evaluate Total Hand Value(FUUAI) of textile fabrics. Tactile sense is important factor which decided the Total Hand Value of a textile fabric. When human feels the FUUAI, physical and physiological phenomena are occurred in finger. We first found out physical variable that is happened in fingertip when human is feeling the FUUAI. Such physical variable means characteristic of action tactual motion of finger such as moving range, tactile time, moved distance, speed of finger and applied force by finger. We study the relationship between action tactual motion and the ability in which the human distinguishes the textile fabric. As a result, we could know the characteristics of the tactual motion of fingertip to get high distinguishable ability. The characteristics were different in men and women respectively. In the case of man, touched time and moving range influenced to distinguish, and moving range, and the moving speed of finger influenced, in woman's case.

This paper compares seat vibrations of a small passenger car and a SUV. The results also include the comparison of the human body accelerations and the ride values, such as the component ride values, and SEAT values of 12 axis accelerations obtained at the human body and seat track. The ride comfort evaluation is usually carried out by experiments of real cars which are expensive and sometimes may contain errors by passenger's postures. Simulations by computer, on the other hand, enable to solve these problems when the accuracy is proven. This paper, thus, also shows the correlation of human body vibration between experiments and computer simulations. For the computer simulation, korean dummy models are developed from the Hybrid III models by scaling the body data of Hybrid III to those of Korean men and women. From the comparison between the test data and simulation data, a nice correlation in trends was shown.

should be in This paper presents review on human comfort criteria in major codes and standards for tall buildings. In general, human comfort criteria of tall buildings have been used by magnitude of wind-induced acceleration response. Two different indexes in determination of the magnitude have been used: the peak value which occurs during a period of time and the rms value averaged over this same period. These distinctive acceleration indexes are discussed in detail and each criterium was reviewed and compared. The distinctions arisen because of the different wave forms, or acceleration signatures were addressed. It is described that which index of acceleration should be adopted in establishment of Korean human comfort criteria. In addition, some arguments from a technical standpoint that favor the use of each index are presented.

The effect of electric shock on human body is enormousness, which leads to warmth, tingling, and even death. The mean values of perception currents obtained on 91 men and 39 women are about 0.77(mA) for men and 0.57(mA) for women. The mean value for women is approximately seven tenths that of men. An individual can tolerate, with no adverse effects, repeated exposure to the reactions associated with currents of his let-go level, and the mean value of let-go currents obtained from 27 normal men is 6.29(mA). Lethal currents flowing human body is very dangerous even for a short time. So, it is necessary to have recourse to animal experiments ot determine lethal current for human. An analysis of experimental data indicates that body weight and shock duration are important factors in determining the lethal current. It is suggested that the relationship between current and shock duration is given by I=K/.root.T, and lethal current is proportional to body weight, where I is the current in milliampere, and T is the time in seconds.

In Laozi Tao(道) is not only the universal law of all existence but the eternal law of morality. In Laozi Tao as the eternal law of morality is the absolute criteria of value-judgement. In this respect in Laozi Tao is the perfect value or the absolute criteria of value-judgement. And so someone can evaluate Laozi's perspective on the theory of value is value-absolutism. Nonetheless, Laozi allows all theories of value in Laozi. Laozi's thought on the value is indifferent to what kind of value one has. But Laozi's ideal of the theory of value is value-universalism through Tao as the absolute criteria of value-judgement. So in Laozi the perspective on value is the universalization of value-absolutism. In Laozi, the medium of value-universalism is being of Sage(聖人) and all human's inpersonation of Teh(德). If this two conditions fulfilled, all human beings can reach the state of "subtle identification(玄同)" and can be sages, and value-universalism take the form of valuelessism.

This paper presents a study on the characteristics and safety criteria for human body in ELF (Extremely Low Frequency : 50-60Hz) electric and magnetic fields. Many researches for ELF electric and magnetic fields, which are developed in the past, are studied and analyzed In this paper. In order to estabilish the safety criteria for human body in the field, the field intensity, induced current and voltage are calculated by the electrostatic field approach which is far simpler than the electromagnetic field one based on Maxwell equation. The method is applied to the 345 KV transmission line system In operation and 765 KV system under consideration. According to the results, the maximum value of field intensity, 6.8627KV/m, is evaluated at the location which is 14m away from transmission line. As the safety criteria value by the abroad researches asserting that the human can detect the Induced current in 6KV/m and above, 5KV/m and 7KV/m are recommended at residence area and nonresidence area, respectively.

This study explores the value structure of experiential rental Hanbok companies using the means-end chain theory. For this, soft laddering was conducted for nine experiential rental Hanbok companies located in Jeonju Hanok Village. Next, the value structure was created. The results are as follows. First, the elicited values are in the following order: "creation of wealth," "promotion of Korean culture," "aesthetic value," "self-actualization," "community development," and "transmission of tradition." Second, most attributes are connected to "creation of wealth." Third, "promotion of Korean culture" and "community development" are similar to Holden's instrumental values. Fourth, some attributes linked to "aesthetic value" express what the experiential rental Hanbok companies consider to be beautiful. Fifth, the companies pursue "company satisfaction" through "consumer satisfaction" and "company differentiation," which leads to "self-actualization" and "aesthetic value." Sixth, it seems that "transmission of tradition" can be achieved through "expertise/expert training," indicating that some companies think expertise is necessary for the transmission of Hanbok and do it. This study is significant because it is a new attempt to understand the core values of experiential rental Hanbok companies and provides insights into their growth.
