Company strategy that considers market trend becomes a more important key to success in the new product development. Well-being as a present social trend has created a huge new product market. but with increasing number of camouflaged well-being products that are not fulfilled consumer needs. The purpose of this study is to understand the concept of well-being products from a consumer point of view an to find five consumer values based on the consumer value model of Sheth, Newman, and Gross(1991) through conducting content analysis from semi-structured individual In-depth Interviews. This study has a significance in identifying the detailed consumer value attributes and influence factors by collecting practical and reach qualitative data in the lack of systematic research of domestic well-being market and its products from a consumer point of view. The result of this study will be a foundation of future quantitative researches and provide a guideline to companys' well-being marketing strategy.

This qualitative nursing research used a hermeneutic phenomenological approach to discovery of meaning of the nursing students' clinical experience in junior colleges. Data collecting was utilized by in- depth face-to-face interviews of 10 sophomores who were participating in their first clinical experience. The following themes of the experience emerged. 1) The first step of fear (fear, being embarrassed) 2) Rhythmical patterning of theory and practice(disappointment of nurses, recognition of the gap between the theory and practice, the conflict between medical doctors and nurses, trouble with the students from other colleges, confusion from nurses' educational and noneducational attitudes, burden of responsibility for nurses' jobs, and the tiresome nature of repeated practice) 3) Discovery of changing self, awareness of self-expansion (awareness of professional nurses' roles, formation of self-confidence, changing of one's state of mind) From this study essential theme of clinical experience of nursing student's was identified, and continuous efforts to establish better adaptation of nursing students to clinical practice are required.

This Qualitative nursing research used a hermeneutic phenomenological approach to discover meaning in an self-transcendence experience. The ultimate aim of the inquiry was to discover the essence of self-transcendence experience and to promote understanding. The study used van Manen's Methodology of phenmonological research. Multiple strategies for data collecting were utilized : in depth face-to-face interview and analysis of elders' literature. The following themes of experience emerged : Accepting becoming older as a natural phenomenon, transferring to one's own sons' and daughters' oriented life. Maintaining harmonious relationship with neighbors and peer, observing real situations with silence, forming internal integrity with perseverance, compromising own's real situation, actualizing one's death, giving up roots of life, depending on God and conforming to human limitation. From this study essential themes for understanding self-transcendence experience and needs for continuing inquiry were identified.

This paper introduces a branch of qualitative method, called an in-depth interview method. By collecting data from the stories of Korean middle school students and a 9th grade American girl who used Geometer's Sketchpad and various software respectively for their mathematical problem solving, the qualitative analysis leads us to understand how such software affect their lives with mathematics subject. The unique characteristics and strands of each student's utterances reflect how software plays a role of learning aid for their mathematics learning. The arm of this study is both to get a good picture of each student's self-perceived relationship to mathematics as well as to explore external and objective parameters and factors in each student's internal situations. The qualitative descriptions of the collected data help us guide the students to the points where they could develop their interests and satisfaction with subject matter better. In this way, teachers may have more realistic understandings of how students become interested and motivated by mathematics, so that they are better able to find out ways of grasping the totalities of how the use of technology is interwoven into the school curricular.

Purpose: The purpose of this research was to explore the cyber world immersion experience of adolescents. Method: Multiple strategies for data collecting were used: an in depth face-to-face interview; analysis of adolescent' writings; and analysis of examples of phenomenon in the realistic world. The sample group consisted of 10 adolescents. Results: Although the experience was different for all adolescent interviewed, the essential themes of experience emerged: "fill up", "homoeologous feeling", "the older generation has a conflicting negative opinion", "change in social character", "become habitually skeptic", "have bad health", "mean of superiority and getting everything solved", "ease of access", "monetary benefit", "addiction to the computer", "forget real life solved stress", "do harm to society", "take comfort", or "new job". Conclusion: Accordingly this paper suggests that contact with various software is necessary in adolescents, and good quality contents function to prepare and activate adolescents to apply the internet for good use.

This study was conducted to determine the optimal collecting time and methods of utilization of forest topsoil as a seed-bank source for revegetation materials of slopes. From April to November of 1998, nursery seedbeds in the greenhouse of Seoul National University were seeded with mixtures of forest topsoil and seeds. The nursery seedbeds were treated to evaluate the effect of depths of forest topsoil and seeding amounts. Seasonal experiments with $3{\times}3$ factorial design were conducted in April, June and August. More than 40 seedlings/$m^2$ were observed as the naturally-emerged species in the plot, treated with the top-layer forest soil within the depth of 10cm. However, it was found, as seeding more seeds, the number of appearance of the naturally-emerged species reduced because of the heavy competition between the seeded and the naturally-emerged. According to the results of this research, it is recommended that seeding amount should be no more than 1,000 seeds/$m^2$ to avoid the severe competition. Also it was observed that the forest topsoil collected in spring(April) is better than that collected in summer. The more species of the naturally-emerged were found in the forest topsoil collected in spring. Forest-topsoil-mixed-materials as a seed-bank source could significantly increase the plant diversity and productivity. Effective use of forest topsoil as a seed-bank source may become a valuable tool in future restoration of disturbed slopes for promoting plant community diversity and recycling of spoiled-soils from the slopes.

This study was conducted to solve the problem of crawled spinach harvesting that had been mainly done by manpower on the outdoor fields during the winter season. Moreover, there are not enough workers available for farming at most of rural areas in Korea because farming is getting hard and the number of old-aged workers is increasing. In order to find appropriate methods of digging, picking and collecting of spinach, the tests were examined outdoors. A prototype was designed based on the results of the tests and then fabricated for digging, picking-up and then collecting in continuous operation for harvesting spinach planted in the outdoor fields. In the field test with the prototype, the vibration intensity transmitted to the driver by vibrating blade was low while the vibrating blade reduced digging power by $46\%$ compared to that of the fixed blade. The spinach loss was found to be as low as $0.7\%$ in the condition of digging depth of 40 mm, cam rotational velocity of 748 rpm, and blade amplitude of 16.5 m. The working performance of the prototype spinach harvester was found to be 3.8 hour/10a resulting in $96\%$ of labor saving and $85\%$ of operating cost compared to the conventional manual harvesting.

To determine the optimum operating conditions of the indented cylinder length grader based on varietal characteristics, broken rice removal capabilities were measured on the milled rice of 41 varieties at different conditions consisted of 3 types of indented cylinders with different indent-opening diameters and 3 different collecting-angles of broken rice. The broken rice removal capabilities were swayed by the indent's opening diameter and depth as well as the angle of the collecting trough of broken rice on the point of instrument, and by the kernel length and width as well as 1000 grain weight of milled rice on the point of rice variety. When the angle of broken rice collecting-trough reached to near the horizontal center line of the indented cylinder on the direction of upward turning side, which was referred $0^{\circ}$ in this paper, the amount of rice collected in trough increased, whereas the loss of head rice also increased. Considering the removal rate of broken rice as well as loss of head rice, it was thought that the suitable angle of trough for broken rice collecting was located $5^{\circ}$ to $15^{\circ}$ depending on varietal characteristic and indent opening diameter. It was thought that 4.2 mm or more of indent opening diameter was recommendable for the rice varieties having heavier 1000 grain weight than 22.3g, as well as larger sizes than 2.9 and 5.2 mm in width and length of rice kernel, respectively; 3.8 mm for the small-sized thin kernels, and a proper diameter between 3.8 and 4.2 mm for short to middle kernels. The varieties with relatively shorter length compared to width of kernel were more difficult to separate the broken rice than the opposite ones. For effective separation of that, it seems that some specific indent shapes such as wider opening and shallow depth etc. are required. When the broken rice content were excessively high, wider diameters of indent openings than specified sizes were thought to be the better.
