현대에는 개인 연구자 대부분이 지식생산기관에 소속되어 지식생산기관의 유 형과 지식생산기관 간의 협력이 과학 지식생산에 미치는 영향이 높음에도 불구하고, 지식생 산기관이 정확히 식별되지 않아 과학 지식생산 과정을 실증적으로 파악하는 데는 한계가 있 다. 본 연구는 지식생산기관의 식별 정확도를 높이는 방법을 제안하였다. 구체적으로 디지털 헬스 분야의 PubMed 서지정보를 수집한 후 알고리즘을 적용하기 전 데이터 처리 단계에서 ‘맥락적 연결’을 활용하여 기관정보의 불완전성을 해소하고, 알고리즘 적용단계에서는 기관 명 모호성(IND)을 개선하는 방법을 제시하였다. 본 연구가 산출한 ‘지식생산기관 데이터셋’ 과 동일한 서지정보를 대상으로 하는 기존 공개 데이터셋인 ‘PKG datasets’을 비교했을 때, 본 연구가 제시한 방법은 지식생산기관 데이터셋에 포함된 대상 데이터 수를 2배로 증가시켰으며, 국가별 순위도 보다 정확하게 반영하였다. 또한 한국 지식생산기관의 디지털 헬스 분야 기여도가 과소 또는 과대 평가되고 있다는 사실도 발견하였다. 본 연구에서 제시한 방 법은 향후 과학지식을 생산하고 과학 혁신을 달성하는 데 있어 지식생신기관의 역할을 실증 적으로 연구하는 데 기여할 것으로 판단된다.

A number of studies have been conducted to confirm the preventive effect of xylitol on dental caries as a whole or partial alternative to dietary sugars. This study reviewed the oral health effects of xylitol on the prevention mechanism of dental caries, the prevention of dental caries, the inhibition of mother-to-child transmission, and the oral health effects in the elderly based on existing studies on the oral health of xylitol. Carbohydrates and dietary sugars in food are fermented by acid-producing microorganisms in the mouth and produce dental plaque and acid, which cause dental caries. However, most dental decay-causing bacteria cannot produce acids by metabolizing xylitol. Xylitol, stored in cells as a non-metabolizable metabolite by Streptococcus mutans (S. mutans), affects bacterial glucose metabolism and inhibits bacterial growth. Xylitol consumption also reduces the amount of plaque and the population of S. mutans in both plaque and saliva. In addition, xylitol acts in the remineralization process. Xylitol has been confirmed to effectively prevent dental caries, inhibit mother-to-child transmission of MS, prevent dental caries, and increase salivary flow in the elderly. In conclusion, xylitol is an adequate sugar substitute for dental health, from infants to the elderly. For future studies, the researchers recommend reviewing the effects of xylitol on the oral and intestinal microbial environment and the side effects of excessive intake.

Activities to prevent industrial accidents can be divided into management of disaster risk factors of production facilities, disaster prevention systems and procedures, and human factors management. Human factor management is the last and most effective means to minimize disaster incidence and loss costs. The key strategy for this is safety and health education. However, formal or fictitious education is still being carried out in the industrial field. In addition, it is true that the application of practical use is insufficient due to the simple theoretical education based on knowledge transfer. In order to change the safety consciousness of employers and workers, we think that the paradigm of education should be changed from the traditional text and video-oriented lecture education method to experience-oriented education. The purpose of this study is to measure and analyze the effectiveness of safety education through education contents using VR(Virtual Reality) and AR(Augmented Reality) technology in keeping with the changing times of the 4th Industrial Revolution, And to suggest the direction of future safety and health education and content development trend.

법무부는 정신장애자 범죄가 점진적으로 증가함에 따라 이들을 전문적으로 치료하고 사회적응능력을 향상시키고 이들의 재범을 방지하기 위해 정신질환 수용자들을 위한 정신보건센터를 2012년 이후 4개의 지방교정청관할하에 개원하였다. 이 연구의 목적은 정신질환수용자들이 정신보건센터에서 치료관련 프로그램, 교육프로그램, 훈련프로그램 등 각종 프로그램이 참가자들의 정신관련 치료와 사회적응능력 향상에 도움이 되는지를 알기 위해 각종 프로그램에 대한 분석이 필요하다. 또한 정신보건센터의 운영방식과 교도소 내의 정신보건센터와 지역보건센터와의 연계방안을 고려해야 할 필요성이 있다. 그리고 정신질환자를 위한 보건센터를 더욱 발전시키기 위해서는 외국주요국의 정신질환수형자에 대한 교정처우는 어떠한지를 살펴본 후 우리의 수형자를 위한 정신보건센터의 발전방안을 모색하고자 한다.

In the industrial accident that occurred in the recent contract type of business or establishment (including subcontractor) employers and contractors who demand among employers, would be liable to have a proper discussion on how to prevent industrial accidents. To resolve this issue, it introduced the discussion with the Japanese legal system, which has a system similar to the Occupational Safety and seeks to help us in our country's future institutional improvements.

최근 들어 산업현장 뿐만 아니라 농어촌에도 자동화가 가속화되면서 작업자의 안정성과 편리성을 높이기 위한 다양한 방안이 제시되고 있지만 여전히 농업현장에서 대부분의 작업들이 부적절한 자세로 수행할 수밖에 없는 경우가 자주 발생한다. 본 연구는 쪼그려 앉는 작업자세가 요구되는 각종 농작업에 있어서 적합한 높이의 작업용 좌대를 제공함으로써 부적절한 작업자세를 개선하여 노동 강도를 경감시킴과 동시에 작업능률 향상과 요통 등 근골격계질환을 감소시켜 작업자의 건강

Obesity affects various kinds of adult diseases and is a principal cause of injuring people's health. Physical activities are very important to solve the obesity problem and green spaces are good place to take physical activities. In order to examine the utilization of green spaces for physical activities to improve health, the survey was implemented in regards to recognition of health, forms of use of green spaces for physical activities. Only 8.1% of respondents didn't care about health, but 91.9% of them were interested in health more than ‘commonness’. 95.2% of respondents knew that obesity has an effect on various adult diseases, and 93.1% of respondents cognized that it's possible to prevent obesity by doing physical activities. More than half of respondents replied that the types of green spaces utilized for physical activities were small-scale neighborhood parks and mini parks around house. About 70% of respondents took walking as a type of physical activities. 53% of respondents utilized green spaces one or two times a week, while 25% of them utilized the places at least three times a week to take physical activities. 91.8% of respondents took exercise for more than 30 minutes. These results are expected to promote health because many experts encourage people to take physical activities at least three times a week because fats of human body begins to burn after 30 minutes from start of physical activities. In the utilizing time of green spaces, evening or after work(56.7%) was higher than morning or before work(35.1%). 71% of respondents usually visited green spaces by walking. This study shows green spaces are good places for physical activities and have boundless potentialities improving people's health.
