A long life is the desire of many people. The purpose of this study was to describe long life factors for people aged one hundred and above on Chju island. The research was conducted using a phenomenological method to add understanding to this subject. The field work for this study was done from July, 1997 to February, 1998 on Cheju island. The sample consisted of 10 persons of one hundred or above and 12 families. They were audio-recorded and analyzed using Colaizzi's (1978) method. The results of the present study shows the following: The thoughts of the persons one hundred and above showed ten important concepts; 'dietary regimen', 'mental regimen', 'sleep regimen', 'residence regimen', 'health regimen', 'labor regimen', 'exercise regimen', 'being born', 'filial piety and posterity', 'attachment to life'. Concerning 'Dietary Regimen': Dietary regulation, Preferential food intake, Living on vegetables, Light eating, and concern for longevity in food intake were important. Concerning 'Mental Regimen' : Harmony, Clearheadedness, Mildness, Abstinence, Generosity, Relaxation, Gaiety, Inspiration and Strength were important. Concerning 'Sleep Regimen'; Enough sleeping hours, Sound sleep, Curved sleeping posture, and Comfortable bedding were important. Concerning 'Residence Regimen' ; Clean dwelling, Pleasant surroundings, Thatched house life, Living in the village with good-hearted people, and Regular life were important. Concerning 'Health Regimen'; Temperance of drug, use Proper temperature, Proper humidity, and a Clean body were important. Concerning 'Labor Regimen'; Agricultural labor, Diligence, and Domestic labor were important. Concerning Exercise Regimen': Proper exercise, and Sunbathing were important. Concerning 'Being Born' ; Strong physical constitution, Longevity lineage, and Destiny were important. Concerning 'Filial Piety and Posterity' : Showing respect to a long-lived elder and Reducing anxiety were important. Concerning 'Attachment to Life' ; The desire to live long was important. The following conclusion was made from the above results. Human beings cannot avoid death, but the span of life can be prolonged to the maximum span of human life by wisdom, health care, and proper environmental conditions. As a result, a health regimen must be imposed for longevity such as controling food intake, having positive thoughts, being relaxed, sleeping enough, clean dwelling, taking care of oneself which can improve immunity and resistance to decrease, as well as proper labor and exercise. In addition, when filial piety is served, the desire of longevity and retaining one's youthfulness for a long time can be achieved. These should be done to live long and lead a qualitative life. By the results of this research, the following is suggesed for nursing. To satisfy the basic nursing principle that nursing must be practiced to help people live long, education must be spread to people who are nursed and their family so that they can lead a healthy life. And in nursing elders, nurses must recognize that elders have a strong desire for life, even though they may have negative thoughts about life at times. Therefore nurses have to respect the elders' value of life, and help them improve their self-esteem and self -fulfilment.

장수인구의 공간적 분포 패턴과 지역적 장수요인을 파악하고자 하는 국내의 기존 연구들은 대부분 확증적(confirmatory) 접근 방식을 지향하고 있다. 또한 대다수의 연구자는 통계자료의 가용성에 의존하거나 임의적인 분석 공간 단위를 설정하고 있다. 이러한 연구 방식은 특히 장수 현상이 가지는 공간적인 특성을 충분히 반영하지 못하며 수정 가능한 공간 단위(MAUP) 문제에서도 자유롭지 못하다. 본 연구에서는 인구통계 자료를 이용한 탐색적 공간 데이터 분석(ESDA)을 통해 장수인구의 공간적 분포 패턴에 관한 공간적 자기상관의 발생여부를 파악 하고자 하였다. 이와 병행하여 상이한 분석 공간 단위 사이에서 발생할 수 있는 수정 가능한 공간단위문제(MAUP)에 대한 평가를 수행 하였다. 공간적 자기상관의 발생 여부 파악을 위해 시군구와 읍면동의 상이한 공간단위에 대한 장수 인덱스를 산출하여 전역적 공간적 자기상관 측도인 Moran'I 분석을 수행 하였다. 또한 Getis-Ord Gi*를 이용하여 공간적 Hot Spot 과 Cold Spot 을 파악하였다. 연구결과 시군구와 읍면동의 모든 공간단위에서 통계적으로 유의한 수준의 공간적 자기상관과 장수인구 군집 지역(Hot spot 과 Cold spot)이 존재 하는 것으로 나타났다. 또한 시군구와 읍면동의 상이한 공간 단위에서 산출된 전역적(Global) 공간적 자기상관 지수와 국지적(Local) 공간 클러스터의 값에 차이가 발생하였는데 이는 MAUP의 Scale Effect로 볼 수 있다. 본 연구의 결과는 고령화로 인해 필연적으로 증가하게 될 장수에 대한 연구 시 연구자는 현상이 포함하는 공간적 차원을 고려하여야 하며 MAUP으로 인해 심각한 정보의 오류를 범할 수 있다는 점을 시사한다.

The purpose of this study was to understand how vegetarian diets in Taiwanese hospitals are well established and provide suggestion for successful implementation in Korea. Micro-ethnographic case study with in-depth interviews, field observations, and paper reviews were used for this study. Experiences of doctors and nutritionists from Taiwanese hospitals where deliver vegetarian hospital diets were analyzed. This research found out Taiwanese life respect culture has influence on introducing vegetarian diets in hospital, besides most Participants agreed to use vegetarian diets for the medical purpose according to their clinic experiences and research results. Meanwhile there is no restriction to compel patients to keep vegetarian diets. All participants answered food has a large effect on the human body and further study on vegetarian diets' efficacy is required. The hospital chief's decision making is crucial to introduce vegetarian diets in hospitals. For the bigger picture, social supports, organizational supports and national policy supports are all important factors for it. The implications and recommendations for Korean hospitals were discussed. The public awareness for vegetarian diet for medical purpose along with research on its efficacy would be needed. In order to make good use of a vegetarian diet for medical purposes, we first need to build a vegetarian-friendly environment, go deep into the study of a diet's effects using diverse methodologies, and combine the diet with traditional medicine theory. Based on the results of this primary study, more related studies should be carried out in the future.

Here in this study, we investigated the lifespan-extending effect and underlying mechanism of methanolic extract of Moringa olelifa leaves (MML) using Caenorhabditis elegans (C. elegans) model system. To define the longevity properties of MML we conducted lifespan assay and MML showed significant increase in lifespan under normal culture condition. In addition, MML elevated stress tolerance of C. elegans to endure against thermal, oxidative and osmotic stress conditions. Our data also revealed that increased activities of antioxidant enzymes and expressions of stress resistance proteins were attributed to MML-mediated enhanced stress resistance. We further investigated the involvement of MML on the aging-related factors such as growth, food intake, fertility, and motility. Interestingly, MML significantly reduced growth and egg-laying, suggesting these factors were closely linked with MML-mediated longevity. We also observed the movement of aged worms to estimate the effects of MML on the health span. Herein, MML efficiently elevated motility of aged worms, indicating MML may affect health span as well as lifespan. Our genetic analysis using knockout mutants showed that lifespan-extension activity of MML was interconnected with several genes such as skn-1, sir-2.1, daf-2, age-1 and daf-16. Based on these results, we could conclude that MML prolongs the lifespan of worms via activation of SKN-1 and SIR-2.1 and inhibition of insulin/IGF pathway, followed by DAF-16 activation.

대부분의 사람은 오래 살기를 원한다. 고대 중국과 한국의 신화에 동방삭이라는 인물이 일만 팔천 년을 살았다고 전해진다. 현실 세계에서는 WHO의 보고에 따르면 사람의 평균수명이 1960년대에 50세에서 2016년에는 75-85세로 25~35세가 늘었다. 두 마리의 실험 동물을 외과적 수술을 통해 병렬로 결합하여 두 동물의 순환계(혈액)이 서로 연결되게 하는 개체병렬결합(parabiosis) 실험모델이 1860년도에 개발된 이래 이 방법은 in vivo에서 한 개체가 다른 개체에게 어떤 영향을 미칠 수 있는가에 대한 연구를 위한 강력한 실험 모델이 되어 왔다. 여러 가지 실험조건의 연구 중에서도 개체병렬결합모델은 노화의 진행을 역행하는 현상을 조사하는 연구에서 필수적인 모델이 되고 있다. 본 총설에서는 개체병렬결합모델의 탄생과 이로 인한 중요한 발견을 시간대에 따라 소개하며, 아직은 확정적이지는 않지만 젊은 쥐와 늙은 쥐의 순환계를 연결시킨 이 모델을 사용하여 노화의 진행을 역행시킬 수 있는 "젊음의 인자"인 growth differentiation factor 11 (GDF11)을 발견한 연구 결과에 대해 서술하고자 한다. 지금까지 밝혀지고 있는 여러 조건에서의 연구결과가 증명하였듯이 개체병렬결합모델은 향후 다양한 생리적 현상을 규명하는데 더욱 중요한 실험모델이 될 것으로 예상된다.

Purpose: The aim of this study was to evaluate clinical factors affecting the longevity of fixed retainers and the influence of fixed retainers on periodontal health in periodontitis patients. Methods: In total, 52 patients with at least 2 years of follow-up after periodontal and orthodontic treatment were included in this study. After scaling and root planing, orthodontic treatment with fixed appliances or clear aligners was performed. Fixed retainers with twist-flex stainless steel wires were bonded to the palatal or lingual sides of anterior teeth. Changes in clinical parameters, including the plaque index, gingival index, calculus index (CI), probing pocket depth, and radiographic bone levels, were evaluated before bonding of fixed retainers and at a 12-month follow-up. Cumulative survival rates (CSRs) for retainer failure were evaluated according to sex, site, CI, stage of periodontitis, and the severity of the irregularity with the log-rank test and hazard ratios (HRs). Results: Twelve months after bonding of fixed retainers, improvements were observed in all clinical parameters except CI and radiographic bone gain. The overall CSR of the retainers with a CI <1 at the 12-month follow-up after bonding of fixed retainers was significantly higher than that of the retainers with a CI ≥1 at the 12-month follow-up (log-rank test; P<0.001). Patients with stage III (grade B or C) periodontitis had a higher multivariate HR for retainer failure (5.4; 95% confidence interval, 1.22-23.91; P=0.026) than patients with stage I (grade A or B) periodontitis. Conclusions: Although fixed retainers were bonded in periodontitis patients, periodontal health was well maintained if supportive periodontal treatment with repeated oral hygiene education was provided. Nonetheless, fixed retainer failure occurred more frequently in patients who had stage III (grade B or C) periodontitis or a CI ≥1 at 12-month follow-up after bonding of fixed retainers.

This paper proposes an empirical evidence about contextual factors which determine perceived business performances of small firms resulted from IT investment. In this paper, small firms are defined as firms of which total employees are below fifty. These small firms account for 95% of total number of private companies in Korea. We used a perceived IT performance model based on Balanced Scorecard framework to evaluate IT performance of small firms. And data were collected by Web and e-mail survey method with multiple screening. Statistical results show that business performance of small firms are differentiated in terms of firm size, location, longevity, age of owner, education level of owner, while industry sector, profitability, sex of owner don't make significant differences.

The storing ability of information of optical disks directly depends on the physical property of recording unit cells. It means that the degradation of optical disks ultimately causes the loss of the physical and chemical properties of recording unit cells and leads also information, too. We investigated the degradation and life time of optical disks which tell us the longevity of the preservation of information. Optical disks were aged using the accelerated aging system and studied by optical reflectivity spectroscopy and atomic force microscopy(AFM), and the preservation environment of electronic media in National central library of Korea also were analysed. Results show that the double reflective coated optical disks have good preservation of recording information but revealed some deformation of dye area in the AFM images. It means that we should include the mechanical and chemical degradation of the optical disks in the life time expectation evaluation.
