The number of disabled person is increasing, and also the demand of welfare is increasing. In the developed country, the range of disabled person is broad, because the definition of disability is different among countries. On 10/Apr, 2007, the law to forbid discrimination against disabled person was announced and then it will be operated on 11/Apr, 2008, in Korea. It will need to evaluate conflict between this law and underwriting guideline. There is obvious difference between disabled and non-disabled on risk selection of medical and environmental aspect. More than 50% of disabilities are related to the diseases rather than accident. The role of underwriter is to evaluate the future risk of morbidity (admission and/or operation etc). The insurance company is required to make new product for disabled person and the underwriter has to examine the application of disabled without discrimination, and with respect for the disabled as a human right.

In order to improve the cutting ability of face mill, a model for optimal cutter shape was developed to minimize resultant cutting force by combing cutting force model and optimal technique. Wear test and surface roughness test for optimized and conventional cutter were performed. The new optimized cutter shows longer tool life of 2.29 times than conventional cutter in light cutting condition and 2.52 times in heavy cutting condition. The surface roughness of workpiece by optimized cutter is improved in heavy cutting condition, but deteriorated in light cutting condition in comparison with conventional cutter. The surface profiles of workpiece were analyzed by Fourier transformation. The distribution of cut lay left on workpiece by optimized cutter is more regular than that by the conventional cutter.

Haemocyte characterization in the surf clam, Mectra veneriformis was carried out based on morphological, cytochemical, and phagocytic characteristics. The haemocytes were classified into two cell types, granulocytes and agranulocytes on the basis of presence of cytoplasmic granules. Granulocytes were then classified again into 2 types, large eosinophilic granulocytes and small eosinophilic granulocytes after staining with May-Grünwald Giemsa. In electron microscopy, both types of granulocytes contained electron-dense and electron-lucent cytoplasmic granules. Agranulocytes (hyalinocytes) were also divided into two cell types, large agranulocytes and small agranulocytes based on their sizes. Both cell types did not have granules in cytoplasm. Granulocyte and agranulocyte were negative for the enzyme activities of alkaline phosphatase, peroxidase, and $\beta$-glucuronidase but positive for phenoloxidase and acid phosphatase activities. Both types of haemocytes have phagocytic activity, with the exception of small agranulocyte, and granulocytes seemed more active in this respect than agranulocytes. This present study is the first study to characterize haemocytes of M. veneriformis.

The enterprise life cycle derived from the product life cycle consists of introduction, growth, maturity and decline. The enterprise tries to reach the growth stage early and stay at the maturity stage stably through expanding its businesses and investing for the new technology. The public enterprise is not different but its life cycle is more prone to be affected by the national development and policy. A typical example can be found in the case of the quasi market SOC public enterprise which spends massive amount of fund to provide social infrastructure. After the fulfillment of its mandated mission it is exposed to the pressure of a merger or a closure usually because large portion of the debt is directly linked to the national financial stability and credit ratings. This research is focused on the variables that influence the life cycle of the quasi market SOC public Enterprise for its future competitiveness is in connection with its normalization, advancement and rationalization. In this respect, categorical variables system centering on public characteristics and profitability drew eight categorical variables such as policy outcomes, public benefit, finance and business values etc.

Until 1970's, mankind have not had definite perspectives on what life after the death was like, which is one of the most important problems for them. Their concepts of the 'life and death problem' has been distorted by the dogmas of the established religions such as Buddhism or Christianity on heaven and hell. But the mankind came to have wholly different views on the life after death thanks to the studies by Raymond Moody Jr. or Elizabeth Quebler-Ross in the mid-1970's. This is the studies on the so-called 'near-death experience(NDE)' which made humankind be able to have scientific approach to the life after death for the first time in their history. What attracts our attention at this point is, however, that the arguements of the NDErs on humman destiny accurately coincide with those of the established religions. In the NDE, most of the experiencers have an encounter with the personal being, symbolized by the Light, through whom they learnt that the devotion(or love) to the neighborhood and the gain of the wisdom are the sole meaning of life. With this result, we can recognize why essential virtues maintained by the established religions until now such as ultimate compassion, unconditional love, forgiveness, or insightful learning are so significant, and that our studies of the NDE are very important in this respect.

This study aims at the extraction of what is universally to be taught in modern Korean Families and its scalization. That is it attempts to provide the criterion by which we can determine what to teach children in the family not in society or school. For this purpose this study firstly reviews the preceeding studies on the subject. As a result of the review we postulate the hypothetical structure consisting of 12 domains. Secdndly we gather the parent's view on the topic by interviewing 192 parents of the students. On the basis of this study we can construct the questionnaire(Likert scale; 5 point) After we conduct an extensive empirical research(518 parents) in order to generalize 179 items of the worked-out questionnaire. We apply factor analsis(principal axis factoring oblique (promax) rotation) in the verfication of the validity. As the consequence we select 87 items consisting 15 factors which explain 71% of common variance. We name the 15 educational factors extracted in the scale as follows; Values & Sociality Training for basic living habits The maintenance of the culture life on the family Religious life Learning guide Economic life Patriotism Independent living Table manners The management of commodity The preservation of family unity Sex & a Frendship with the opposite sex Esteem for a traditional way of life Respect for the Old Filial piety. The reliabiliy of the scale is the cronbach a=.96 which turns out to be satisfactory.

High-speed machining generates concenter thermal/frictional damage at the cutting ed rapidly decreases the tool life. This paper I at determining the effect of cutter orienter the cutting environment on tool life, tool mechanism when down milling. In this paper, experiments were carried out in various tool and cutting environments, such as dry, wet compressed chilled air, tool life were measu evaluate machinability in high-speed milli difficult-to-cut material and die steel, Tool measured in horizontal upwards, horiz downwards, vertical upwards and vert downwards. In addition, tool life was measur dry, wet and compressed chilled air. For this a compressed chi1led-air system was manufact The results show that a horizontal cutter ori provided a longer tool life than a vertical orientation. With respect to the cutting envi compressed chilled air increased tool life. H the wet condition decreased tool life due thermal shock caused by excessive cooling high-speed mill ins and the compressed chilled had little effect.

The purpose of this study is to ascertain the actual conditions of volunteering activities in respect to age-integrated leisure. This study is based on the 2010 Korea Leisure Life Survey. The participants in this study were 3015 people who reside in Korean cities, except for Jeju-do. Questionnaires from the 2010 Korea Leisure Life Survey were used for the final analysis. Data were analyzed through a descriptive analysis, Chi-Square test and ANOVA by SPSS WIN 17.0. The findings indicated that 18% of the participants participated in volunteer activities as leisure in the last one year. The major findings were as follows. First, demographic characteristics such as age, academic career, income, and marital status had a positive correlation with the degree of volunteer participation. Second, there were differences in duration and field of activities according to age. Third, though most of the non-volunteer reasons were 'lack of resources', there were different reasons based on age. In detail, the reason for 10-50 year-olds (economically active population) was 'lack of time', but the more than 60 year-olds was 'health concern'. Consequently, this access to the life cycle study shows the need to improve life satisfaction.

This study aims to analyze the elements to enhance and activate the quality of life by establishment of family-friendly environment through face-to-face interviews in family-friendly certified firms in UIsan. As a result, its activation is possible when each party of companies- employees-government tries to change, and its main elements and outcomes are as follows. First, 'management philosophy of the company representative' showed to directly affect development of flat organization culture and system activation, with respect to the companies. Second for employees, 'value changes to prioritize work-life balance' demonstrated to affect the utilizations and establishment of family-friendly systems within the organization as the critical element. Lastly, it is considered for government to be able to activate this if 'delivery system with professionality' is secured to help 'legalization of policy,' company productivity, and work-life balance of employees. On the other hand, further studies on the elements to be able to activate family-friendly certifications and analysis on its justification are required by expanding the number of companied in Ulsan.

Purpose: It is to survey old men's utilization status of dental clinic and temporary-binding dentures and then to provide basic data to make a program for manufacturing old men's dentures and their teeth health education. Methods: Random selection was made on old men living in Daejeon and Chungnam, and a survey was conducted from April 15 to May 20, 2011. 500 questionnaires were distributed and 420 questionnaires were collected. Using spss 18.0 program, final analysis was made on 363 questionnaires except for 57 questionnaires which had missing value or showed some doubts about the unreliability. Results: 1. With respect to number of natural teeth as per the age, the upper/lower jaws had meaningful differences (P<.001), which means that the older the person is, the smaller number of natural teeth is. In the meantime, there was no meaningful difference according to sex. 2. With respect to kind of prosthetics installed in a mouth as per the age, there was meaningful difference in the upper jaws (P<.05) but there was no meaningful difference in the lower jaws. It was found out that the older the persons are, the more they use removable dentures while the younger the persons are, the more they use fixed partial dentures. 3. With respect to mouth health condition recognized by oneself, it showed bad (44.4%) and good (10.3%),which means recognition as bad is greater, and the age when prosthetics were first used is dispersed variously from below 40 to over 70. 4. Dental care institutions which they mainly used are hospital and clinics (91.5%), and 66.4% of them visited dental clinics lately. Preferential treatment if they go to dentists is as follows in the order of prosthetics (33.9%), gum treatment (24.2%) and pain treatment (14.9%). 5. 68.4% of them revisited dentists after installation of dentures and the reason for revisit is as follows in the order of poorly fitted dentures (35.1%), painful gum 25.9%, regular check-up 25.4% and difficult chewing 9.6%. Conclusion: As our country enters into an aging society, mouth health problem of old men has come to a serious issue, and therefore, a survey was conducted on some old men with respect to their utilization status of dental clinic and removable dentures in order to provide basic data for improvement of quality of their life, maintenance and enhancement of their mouth health. The study result shows that the older they are, the higher the loss rate of teeth as well as needs for prosthetics are, and thus it is thought the study will help to develop mouth health education program which may improve quality of old men's life by recovery of mouth functions declined due to loss of teeth and by regular check-up, education for mouth health control and following-up control of dentures.
