In this paper, the maximum likelihood estimators and confidence intervals for parameters of Weibull distribution are derived under three level constant stress accelerated life tests and the assumption that a log quadratic relationship exits between stress and the scale parameter ${\theta}$. The compound linear plan proposed by Kim (2006) is used to allocate the test units at each stress level, which performed nearly as good as the optimum quadratic plan and had the advantage of simplicity. Some simulation studies are given.

Objectives : The aim of the present study was to propose more substantial data for evaluating the quality of life of adults in terms of oral health as well as provide the basic data necessary to develop an effective oral health care program that improves the quality of life of adults by age group. Methods : Raw data were used from the sixth Korea National Health and Nutrition Examination Survey for the first and second years which was conducted from January 2013 to December 2014. Multiple regression analysis was conducted with the collected data by gender and age group to determine the impact of oral functions on the quality of life of adults. Results : It turned out that oral function has an impact on the quality of life of adults by age group as follows: young people (${\beta}$=.077), middle-age people (${\beta}$=.101), young-old elderly people (${\beta}$=.140), and old-old elderly people (${\beta}$=.143). It was shown that as people grow older, they have better quality of life only when they have good oral function. Conclusions : It is necessary to develop a proper oral health care program that prevents oral diseases and improves oral function by age group, which eventually will lead to good oral health. Continuous oral healthcare is also considered necessary.

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms r-reliability (failure rate) and durability (product life) are explained. The conceptual analysis of failure mechanics explains that reliability technology pertains to design area. The desirable shape of hazard rate curve of electronic items, hockey-stick line, clarifies that Mean-Time-to-failure (MTTF) as the inverse of failure rate can be regarded a nominal life. And Bx life, different from MTTF, is explained. Reliability relationships between components and set products are explained. Reshaped definitions of r-reliability and durability are recommended. The procedure to improve reliability and the reasons for failing to identify failure mode are clarified in order to search right solutions. And generalized Life-Stress failure model is recommended for the calculation of acceleration factor.

Purpose: The purpose of this study was to describe and understand the meaning of cancer survivors' life experience after being discharged from the primary cancer treatment. Methods: Data were collected through a tape-recorded in-depth interview from six participants living in Gyeonggi province from September 2007 to January 2008. The analysis of the data was made through the phenomenological analytic method suggested by Colaizzi. Results: Thirteen themes regarding the survivors' life experience were found. From these thirteen themes, six major theme were emerged. The six major theme included 'keeping his/her mind comfortable', 'going ahead with new hope', 'accepting for his/her existing burden', 'maintaining a good health for a new life', 'improving the strength and relationship among the family member', and 'being faithful to his/her religion'. Conclusions: The results of this study would help oncology nurses to understand the cancer survivors' life and to develop a quality of life improvement program for physical, psychosocial, and spiritual aspects of nursing.

An experiment was conducted for extension of shelf-life of cooked squid (Todarodes pacificus) using modified atmosphere packaging. The products were packed in a Ny/PE/LLDPE (0.015/0.045/0.040 mm) laminated film with air, vacuum, CO2 gas, and N2 gas, respectively, and then stored at 5$^{\circ}C$ and 2$0^{\circ}C$. Keeping qualities of the products were investigated by measuring moisture content, H, volatile basic nitrogen (VBN), viable cell count, thiobarbituric acid (TBA) value, peroxide value (POV) and color value. Good qualities of the products stored at 5$^{\circ}C$were maintained at least 9 days, 11 days, more than 35 days and 24 days in air, vacuum, CO2 gas and N2 gas packaging products, respectively. In cases of 2$0^{\circ}C$ storage, however, the shelf-lives of all the products were only one day. The shelf-life extension of the products were observed in CO2 ga>N2 gas>vacuum>air packaging in order.

Edible coatings are one of the most innovative methods to preserve the quality and increase the shelf life of fresh fruits and vegetables. A successful edible coating should have a barrier against gases, especially oxygen and water vapor, and have good surface characteristics. Today, chitosan coating is widely used due to its properties, such as non-toxic, biodegradable, and biocompatibility. Is. Coating the surface of fruits and vegetables with chitosan increases shelf life due to reducing weight loss and reducing respiration rate and also reduces decay due to its antimicrobial and anti-fungal effect. This work discusses the effect of using chitosan coating containing chamomile extract to increase fresh vegetables'shelf life. In addition to increasing the shelf life of vegetables, this method can be used as a solution for the economic management of human resources. The results of this method confirm the successful synthesis of these nanoparticles, and the results of applying this food coating on vegetables have been successful. They have increased the shelf life of vegetables such as basil and spinach.

이 논문은 주로 사서(四書)를 중심으로 유가에서 도덕(義)과 물질적 이재(利財)의 관계를 규명하고, 그 특징을 살펴보는 것을 목적으로 한다. 이를 위하여 우리는 의(義)와 리(利)의 원의를 살펴보고, 이 용어가 사서에서 어떻게 사용되고 규명되고 있는 지를 살피면서 도덕과 물질적 리재에 대한 유가의 입장의 특징을 제시하였다. 유가는 도덕적 행위자를 군자(君子)로 규정한다. 그리고 유가는 행위의 준거에서 옮음과 이익을 대립시키면서, 군자는 항상 '옳음'에 따라야 한다는 것을 주장한다. 이렇게 행위의 동기의 측면에서 대립되는 의와 리는 곧 의리지심(義理之心)과 이욕지심(利欲之心)의 대립이라고 할 수 있다. 그런데 '리(利)'에는 소리(小利, 이욕(利欲))와 대리(大利, 공리(公利), 복리(福利))의 구별 및 '수확물로 삶을 윤택하게 함'과 '순조롭게 조화를 이룸(의지화자(義之和者))'이라는 또 다른 의미가 있다. 그래서 유가는 소리(小利, 사욕(私欲))의 추구는 비판하지만, 모든 백성들에게 이익을 가져다주는 대리(大利)로서의 공리(公利, 복리(福利))를 지향하는 정책을 시행하고, 진정한 리(利)란 치자가 의(義)를 실천했을 때 공평하게 분배되어 조화로운 상태라고 주장한다. 그래서 유가는 치도(治道)의 방법을 제시할 때에는 '선부후교(先富後敎)' 즉 먼저 백성들의 의식주를 충족시켜 준 다음 학교를 통해 오륜(五倫)을 가르쳐 인간다운 삶과 도덕을 추구하도록 가르쳤다. 결론으로 우리는 도덕과 이재(利財)에 대한 유가의 입장을 정리하였다. 그것은 곧 유가는 1)인간적인 덕(德)과 이재를 본말관계(德本財末)로 파악하며, 2) 부의 편중을 비판하고, 신분에 따른 분업과 균등한 부의 분배를 강조하였으며, 3) 부당한 주군) 및 정부를 위해 일하지 말 것을 권고하고 있다는 것 등이다.

PURPOSES : Concrete pavement has been used in the construction of the Jungbu expressway in 1987. More than 60% of the pavement on the expressway is currently made of concrete, but most has been used far beyond their design life. Pavement life has been extended through routine maintenance or overlay. However, the structural capacity of the pavement has reached its limit, and extensive rehabilitation/reconstruction with long time traffic blocking should be considered. The three following issues on concrete rehabilitation/reconstruction will be discussed: (1) economic comparison of asphalt inlay and asphalt overlay, (2) economic comparison preventive overlay on a section which is currently good and routine overlay on the section which will be poor, and (3) economic analysis of early-strength concrete when it is used in concrete reconstruction. METHODS : First, various life cycle cost analysis tools were compared, and the proper tool for the extensive rehabilitation/reconstruction was selected. Second, a sensitivity analysis of the selected tool was performed to find the influential input variables, which should be carefully selected in the analysis. Third, three case studies, which can be issues in the rehabilitation/reconstruction of the expressway concrete pavement in Korea, were performed. RESULTS : Asphalt overlay without milling the deteriorated concrete showed 18~25% lower life cycle cost than the current asphalt inlay with milling. The good current preventive overlay on the section was economically justified within the scope of this study. The construction cost limit of the early strength concrete was suggested to be economical for 1, 3, and 7 days of construction alternative opening. CONCLUSIONS : CA4PRS was a viable tool for comparing various rehabilitation/reconstruction issue alternatives. Several concrete issues associated with the rehabilitation/reconstruction of the deteriorated concrete pavement were discussed as mentioned above.

The aim of this study is to analyze the meaning of Korean elders' reminiscences by analysing korean novel literature from 1930s to 1990s. The results of this study are as follows : The moaning of elders' reminiscences are the reflecting on their life, conquesting the excessive fondness the regrecting, the pursuiting of the powers, the pursuiting of the love(Jeong) and the conformation of their exsistence. Elders have tried to examine their life through reflection on their life tha? they did not live good life as son and daughter for parents and as parents for children and that they have foolishly lived, on dream that they did not come true, on their learning that they did not unsatisfied. But elders conquest the excessive fondness. They have felt their limitations of power in the conflict of human relation, the economic matter and the difficult predicament, and have finally accepted their life as it is by conquesting from their tenacity. It is dynamically found that both the reflecting on their life and conquesting of the excessive fondness. And they pursuit the powers. It means the pursuit of the vital powers, the vigorous powers and the competency, Elders have pursuited their vitality, vigor and competency through their reminiscences and have wanted to be recognized by others as a powerful being. These have dynamic and compounded aspects. Elders have pursuited the purely love (Jeong) through their reminiscence togather with their sisters and brothers. And the confirmation of their exsistence refer to through their own situation of health, condition, children, neighbourhood and doing their duty as a human. Elders have confirmed the present value of their being through the reflecting the present, past self, other men around themselves, children, neighborhood and the doing their human duty as a good men. Therefore the results of this study can offer new view on the elders' reminiscences that we have to understand them as a process as what they are, escaping from the simple logic that elders' reminiscence have a positive or a negative effects. Also, this study which have examined the natures of Korean elders' reminiscences can cast a new light on elders' nursing proper for Korean culture.
