Purpose: We performed a randomized, double-blind, placebo-controlled trial in mild to moderate myopia patients to evaluate the benefit of taking a nutrient supplement containing anthocyanoside oligomers for improving nocturnal visiual function and/or clinical symptoms. Methods: The subjects included have refractive error between -lD(Diopters) $\~$-8D in both eyes, symptoms of decreased night vision and asthenopia based on the scoring result of a pre-structured questionnaire, and abnormal results of mesopic contrast sensitivity(MCS) screening test showing abnormal curve of contrast sensitivity in the middle and high frequency level, between 6.0 and 30.0 CPD(Cycles per degree) at mesopic condition(-2$\~$0 log cd/$m^2$). Total 60 people who qualified the criteria above were enrolled and the subjects were instructed to take the investigational product (anthocyanoside or placebo) twice daily for a 4 week period. The enrolled subjects were investigated for nocturnal vision performance by MCS and clinical symptoms at their first visit and re-evaluated at post-intervention (4 weeks later). MCS was measured and improvement of contrast threshold level according to each CPD was calculated by subtracting initial values from final values. Age, refractive error, and MCS were compared between the placebo and anthocyanoside. Results: After 4 weeks of drug administration 22 of the anthocyanoside group showed symptom improvement compared to 1 of the placebo group (p=0.000). Contrast sensitivity levels according to each CPD before and after drug treatment showed significant improvement in the anthocyanoside group but not in the placebo group. Mean MCS change of anthocyanoside group is 2.41$\pm$1.91 which showed significant improvement compared to -0.40$\pm$2.47 of the placebo group(p=0.000). MCS changes of anthocyanoside group showed significant improvement compared to placebo group in all levels of CPD(p<0.05). During our investigation none of the subjects complained of specific side effects related to anthocyanoside use. Conclusion: Our results show that under careful selection of people with significant symptoms and definite MCS abnormalities, anthocyanoside oligomers may improve the subjective symptoms and objective MCS results.

Narcotic drugs generally refer to serious and habitual hidden rash such as opium, heroin, methyphetamin, nabinol, cocaine, and so forth. At present, narcotic drugs are spread unchecked and are causing a big social problem. So many countries and narcotists are making every effort to set up a barricade against narcotic drugs. And there is a limit suitable treatment for them. Thus Tuo Yin Tang hang is developed. As indicated by Chinese letters, Tuo yin Tang Jiang(TYTJ) is a crude drug. It is a traditional chinese medicine developed by the study done from lune in 1998 to lune in 1999 that Hubeisheng was entrusted with by People's Republic of China. This study is a treatise on etiology and syntomatology or narcotism. TYTJ is a medicine which is in accord with Pharmacopeia of the People's Republic of China in order to remove from the body the toxic materials resulting from narcotic drugs such as opium and heroin. According to the standard diagnosis on narcotism, 105 cases are studied and treated at the Rehabilitation Center attached to Enshi Autonomous Region Hospital in Hubeisheng. 105 cases are divided into 2 groups by double-blind method. One is the experimental group which has 56 cases. The other is the control group which has 49 ones. 13 cases among 105 cases are addicted by intravenously injections. 9 cases are by oral takings. It took 10 days for this experiment to be performed. Two groups didn't show a striking individual variation based on the age, gender, period of taking drugs, withdrawal symptoms, complication, and state of health. The experimental group had a higher effect of treatment than the control group had. TYTJ treats diseases effectively and has no side effect, irrespective of the serious or slight addiction to opium and morphine.

Purpose : This study examined the relationship between oral health management behavior and subjective health perception by using a tool that measures health-related quality of life named EQ-5D. The findings are expected to provide fundamental data for developing diverse programs, including health- and oral-health-related educational media, to ultimately enhance people's health-related quality of life. Methods : Adults over the age of 20 were extracted from the raw materials of the 8th national health and nutrition examination survey conducted in 2019. Among them, 4034 were finally chosen as the study subjects after checking the response distribution of relevant questions and excluding inadequate samples. Variables included general characteristics, health management behavior, oral health management behavior, subjective health perception, and EQ-5D level. Cross-tabulation test, independent t-test, one-way analysis of variance, and linear regression analysis were conducted using SPSS 25.0. Results : EQ-5D, which measures the level of health-related quality of life, was high when the subjects had a medical check-up experience, no experience of unsatisfactory medical service, and did not get an influenza vaccination (p<.001). The quality of life was higher when the subjects received dental inspections, did not require treatment, and used oral care goods (p<.005). Health-related quality of life was also higher when the subjective health level and subjective oral health level were high. Conclusion : Results indicate that subjective health, oral health perception level, and quality of life together were high when people had a regular check-up, did not neglect treatment, and used oral care goods. Considering the findings of this study, check-up programs that are customized for each age group are necessary. Health-related quality of life could be enhanced through the provision of diverse medical services and active efforts to prevent any medical blind spot.

This study was conducted to find ways to utilize human-centered IT in caring for elderly people who live alone. Through focus group interviews with experts, this study investigated the problems with delivery system, and ethical issues. Problems such as lack of trust, supplier-centered care, and uniform service provision were derived as major problems in the delivery system. These findings indicate that IT should be used as an auxiliary means of face-to-face services and to be controllable and convenient. Issues such as "guaranteeing the right to self-determination," "protecting privacy," "sufficiently guaranteeing the right to know," and "encompassing blind spots" were raised as important ethical issues related to human-centered IT utilization. Based on the research results, this study presented the necessity of designing user-centered information technology and the necessity of developing ethical indicators for the use of human-centered technology.

Purpose: Compared to cities, rural areas are in a medical blind spot and face difficulties in accessing medical services due to inconvenient transportation facilities, lack of medical facilities, and the heavy burden of medical expenses. This study was carried out to identify the problems relating to the musculoskeletal system of the elderly in rural and fishing villages, which are medically vulnerable areas, and sought to present a regionally differentiated healthcare model. Methods: The study was conducted in 80 elderly people in two rural villages and two fishing villages after seeking inputs regarding medically vulnerable groups in the Gyeongnam Province. Postural balance and muscle flexibility were assessed and postural evaluation was conducted to identify musculoskeletal problems and gait stability. Strength and range of motion for each body segment were assessed for evaluating functional motion. Results: The elderly in both rural areas showed forward head posture characteristics. The strength level of the elderly in both rural areas was higher than the average, but their flexibility and balance ability were lower than the average. Conclusion: The musculoskeletal problems of the elderly in rural and fishing villages in this study did not show regional characteristics according to the area of residence. However, overall flexibility and balance ability appeared to be reduced. Therefore, a new management model connecting the region and the university is necessary in preparation for the coming era of community care.

Advances in information and communication technology have introduced self-service technologies (SSTs) to service companies, changing the way they serve. In addition, as SSTs are expanding for low cost and high efficiency, opportunities for technology to interact with consumers have increased. Restaurant managers have the advantage of the SSTs win-win strategy, which allows consumers to freely receive the products or services they want, but some consumers have low satisfaction of the SSTs, especially elder people and the blind. This study examines the effect of unmanned order payment technology on service quality evaluation. For this, we interviewed a total of 12 consumers in their 10s to 50s with the experiences of using unmanned order payment technology, applying the Grounded Theory Method(GTM). Through a review of the research participant interview materials, totally 84 concepts were derived and the concepts were analyzed to derive 15 subcategories and 10 upper categories. Finally, a paradigm model of the effect of unmanned order payment technology on service quality assessment was derived. It also found the importance of consumers' sense of obligation to use unmanned order payment technology, recognition of advantages (e.g., time savings), recognition of shadow labor, and recognition of whether the technology usage process is in the service quality assessment stage.
