The purpose of this study is to consider factors such as one's sight of viewing afar, expressional principles, and basic aesthetic category, which are treated importantly by the poets of the Joseon Dynasty era in appreciating nature. 'Afar' of the viewing afar is actual distance and aesthetic distance at the same time. Viewing afar is to find geographical features, depth, and details of a mountain, seeing the whole nature at a high place. Also, it can make possible escape from the external limitation of nature and get mental superiority and enhancement. Ultimately, viewing afar is to find out everlasting change of the nature and reason of natural creation. One's sight in viewing afar makes an appreciator's mind empty and calm, and it makes chance to harmonize human with nature. Viewing afar is to unite human nature to naturality beyond realistic value, idea, and artificiality. The mind from viewing afar has peacefulness and it is a state of serenity without any secular atmosphere. Viewing afar is an eye for beauty to leap toward an endless free state from narrow sight about objects. It rejects modification and technics in achieving an world of harmony. It means that objects should not be restrained by human's recognition. There are three expressions, which are high, horizontal, and transcendental viewing afar. The aesthetic category and beauty of peaceful mental state are realized by the expressions. The peaceful mental state makes peaceful mind from realistic conflicts and makes us experience a profound reason of nature.

The purpose of this study is to find biomechanical parameters for optimal shoes production through an ergonomic usability assessment of five existing types of shoes preferred by B-BOY. Ten experts and ten non-experts participated in the experiment, and 12 infrared cameras (Qualis, Oqus), force plate (Kistler, 9286AA) and foot pressure plate (Zebris Gmbh, Zebris PDM-System) were used to obtain the data. The results of the study are as follows. First, P shoes with a friction coefficient of 0.38 and a free moment of 0.32 N/m/kg are desirable in terms of traction capability and safety. Second, on the cushion, it was found that the N shoes 2.51 N, sec/kg and non-expert, and 2.86 N and sec/kg were suitable. Third, it is deemed appropriate for C shoes with a forefoot average pressure of 10.11 KPa (right), 10.05 KPa (left), and V shoes with a rearfoot average pressure of 8.4 KPa (right) and 8.36 KPa (left). In conclusion, the combination of the structure and material of V shoes should be developed for traction and stability, N shoes for cushion, and walking balance for C and V shoes.

This study attempted to discover the dimensions of Korean culture, with the presumption that the cross-cultural studies(Hofstede, 1980, 1997; Schwartz, 1992, 1994; Trompenaars and Hampden-Turner, 1997; House et al., 2004) have limitation to explain non-western culture including Korean culture. Even though there are some Korean cultural studies, they used heuristic approaches applying the authors' experiences and intuitions. This study applied the Cultural Consensus Theory to overcome the previous studies' shortcomings and to discover the dimensions that can be empirically proved by data. In specific this study conducted in-depth interview, used content analysis, did frequency analysis, and applied pilesort technique, multidimensional scaling and network analysis. As a result, this study obtained five categories: public self-consciousness, group-focused orientation, affective human relations, hierarchical culture, and result-orientation. It is expected that these dimensions can be used as important variables that may explain Korean social phenomena.

The aim of this thesis is to elucidate the meaning of play which constitutes the genuine happiness of human being in Plato's '$heort{\bar{e}}$' and Aristotle's '$schol{\bar{e}}$'. Until now '$heort{\bar{e}}$', a divine act which communicate with original divinity, was differentiated from paidia. And '$schol{\bar{e}}$' was understood as activities in spare time opposed to labour. Plato put '$heort{\bar{e}}$' at the center of their life as a means for gods' blessing. Aristotle understand '$schol{\bar{e}}$' as free activities and the completion of individual life. For Aristotle play is not only a freedom from labour but also a supreme activity. Play itself is an end and a completion. Play is the essence of human life so man can be happy with play. Play is the activity of joy. And play is the most intellectual and spontaneous activity. Now we can assert that '$heort{\bar{e}}$' is the original play which elucidate the existence of the human being in connection with world and is the holy mode of play which makes an affluent life of communities. And we can maintain that '$schol{\bar{e}}$' is a mode of play which freed from the burden of labour and elevate the life of human being to academic activities and contemplative life. By this interpretation we can expose that play is the center of life. We can see the two fold meaning of apollonian-dionysian play and the perfect harmony of communities in Plato's '$heort{\bar{e}}$'. We can see also the delight as splendidness of life in Aristotle's '$schol{\bar{e}}$'. The Plato's theory of play seems different from Aristotle's. But their theories are the same in the general, because they both put play at the center of life and they equally assert that we have to live with playing our life. The world in which play is in harmony with labour- this world is their utopia.

To assess the reliability of chronobiological models of sleep/wake regulation, it is necerssary that the models predict the data which has been studied in sleep research, and they should be generalized across all ages. To date, many adult human data on such models have accumulated, yet it is evident that a comprehensive theory of the biorhythmic aspects of sleep/wake states has not established. Circadian rhythms such as the time going to bed, sleep onset, slow wave sleep pressure, periodicity of REM sleep, daytime performance, and early evening alertness are resumed everyday. Even in adult humans, sleep is inherently polyphasic. In both the disentrained and entrained states, naps when allowed tend to recur in a temporally lawful manner. The monophasic sleep pattern of most industrial societies therefore appears to be purely of social origin. The endogenous biorhythmic nature of circasemidian sleep tendency is supported by the ubiquity of the phenomenon across all ages. The NREM/REM sleep cycle within sleep with its inherent physiological, endocrine, and neurochemical fluctuations represents the best-documented ultradian sleep rhythms. Also, a daytime ultradian variation in sleepiness with a periodicity similar to nocturnal NREM/REM cycle(BRAC hypothesis) is suggested. This review article provides a brief synoptic review of the evidences for circadian, circasemidian, and ultradian sleep/wake rhythms, and then the authour will suggest the issues which expedite fuller modeling of sleep/wake system, to be further discussed.

A service involves a human interaction between a consumer (customer) and a provider (service worker). In particular, services in today's intangible economy are understood as creative activities that exercise human capital as related goods. Since most service activities are human activities, not objects, they depend on direct interaction between users and service workers, and funeral services are understood as human activities provided by service providers to service targets (deceased, families, condolences). In other words, the funeral service is a service for the deceased, survivors, and condolences in a special situation of death, and can be viewed as a human activity that is exerted by the integration of the interactions between service workers, survivors, and condolences. Functions of funeral services expand for convenience of consumers through the smooth provision of funeral supplies and a variety of complex interpersonal services so that the deceased can perform solemn funeral ceremonies. In this study, the concept and role of funeral services were studied in order to find the direction of funeral services centering for next of kin(families) and condolences, who are the subjects of services from a service-oriented logic perspective. In order to derive meaningful results of people-centered funeral services, funeral services and funeral supplies are classified from the perspective of dynamic resources, guarantees consumers a wide range of funeral choice, and customer dissatisfaction and improvement requests are handled transparently. It suggested a possible plan. Now, in order to improve the quality of life, it is necessary to make efforts to improve the quality of funeral services that improve the quality of death.

The main purpose of this study is to present a map for setting a new direction for future North Korean ministry by applying Russell's theory on Christian education as a mission. As is well known, Russell was the first Christian educator who interpreted Christian education from a mission's perspective. According to her, Christian education is not a mere instrument for church to maintain and nurture new believers, but it is part of 'Missio Dei' in a broader sense. In other words, it is a way for everyone to accept Christ's invitation, and join in 'Missio Dei' that restores true humanity through reconciling with God and our neighbors. Based on the understanding of Russell's Christian education theory, the study examined up-to-date North Korean mission's situation, analysis, and limitations in the introduction. In chapter 2, the researcher reviewed approaching methods for understanding North Korea as well as prior studies on North Korean mission and unification within the field of Christian education. In chapter 3, Russell's theory on Christian education for humanization was briefly introduced. In chapter 4, the study attempted to apply Russell's theory in North Korean mission in the following areas: what is the true meaning of restoring humanity for North Koreans (including the refugees) and what are some of the specific ministry ideas; what is a realistic and sustainable humanization ministry; what environment can foster North Koreans to reconcile with both God and their neighbors; what are the ways to explain that such ministry is an invitation from Christ; what should the people involved in the ministry prepare; in what areas can Russell's theory be more effective in North Korean mission compared to other methods in terms of Christian education for humanization. Finally, a conclusion was drawn in chapter 5.

The purpose of this study was to explore the meaning and essence of experience of family members as care-givers of terminally ill cancer patients at hospice wards. This study was based on the Giorgi phenomenological method, which describes the experiences about the family caregivers. We had in-depth interview with spouses and orthogonal families of nine terminally ill cancer patients. Results were drawn into 13 essential themes, 45 sub themes, and 122 main points. The essential themes are as follows: "cling of life", "bed-keeper", "sacrifice of care", "physical and mental exhaustion during care process","feeling of love and hatred", "avenge on a patient", "self-condemnation", "futility after exhaustion", "consolation of other caregivers", "utmost efforts in resignation", "freedom from suffering", "paradoxical blessing of cancer", "introspected revolution", and "preparation of a dignified death". Implications and limitations are discussed based on study results.

This paper presents a system which recognizes dynamic hand gestures on-line for controlling motion of numan avatar in virtual environment(VF). A dynamic hand gesture is a method of communication between a computer and a human being who uses gestures, especially both hands and fingers. A human avatar consists of 32 degree of freedom(DOF) for natural motion in VE and navigates by 8 pre-defined dynamic hand gestures. Inverse kinematics and dynamic kinematics are applied for real-time motion control of human avatar. In this paper, we apply a fuzzy min-max neural network and feature analysis method using fuzzy logic for on-line dynamic hand gesture recognition.
