이 연구는 대구광역시와 경상북도에 소재하는 각각 3곳의 노인복지관 및 노인대학의 65세 이상 노인 501명을 대상으로 구강보건진료 관리 항목이 자가인식구강상태에 미치는 영향력을 조사함으로써 효과적인 구강보건관리 방안을 모색하기 위해 연구를 실시하였다. 연령에 따른 구강보건진료 관리 항목의 선호도를 조사한 결과, 65~69세는 불소도포, 65~74세는 치석제거, 칫솔질 교습, 70~74세는 틀니 세정 및 관리, 75세 이상은 틀니 제작을 선호하였다. 구강보건진료 관리 항목이 노인의 자가인식구강상태에 미치는 영향력은 현 구강상태가 좋지 않고, 저작지장이 많으며, 구강건조가 있을수록 틀니 제작을 가장 선호하는 것으로 나타났다. 치아수가 적고, 틀니를 가지고 있을수록 틀니 세정 및 관리를 가장 선호하였으며, 흔들리는 치아가 있고, 치통이 자주 있을수록 발치를 가장 선호하는 것으로 나타났다. 연령과 구강상태에 따라 구강보건진료 관리 항목의 선호도에 차이가 있으므로 각 개인에게 맞는 구강보건관리를 적용해야 할 것이다.

피부상태의 진단과 관리는 뷰티산업종사자와 화장품산업종사자에게 그 역할을 수행함에 있어서 매우 기초적이며 중요한 기능이다. 정확한 피부상태 진단과 관리를 위해서는 고객의 피부상태와 요구사항을 잘 파악하는 것이 필요하다. 본 논문에서는 피부상태 진단 및 관리를 위해 소셜미디어의 빅데이터를 사용하여 피부상태 진단 및 관리를 지원하는 빅데이터기반 피부관리정보시스템 SCIS를 개발하였다. 개발된 시스템을 사용하여 텍스트 정보 중심의 피부상태 진단과 관리를 위한 핵심 정보를 분석하고 추출할 수 있다. 본 논문에서 개발된 피부관리정보시스템 SCIS는 빅데이터 수집단계, 텍스트전처리단계, 이미지전처리단계, 텍스트단어분석단계로 구성되어 있다. SCIS는 피부진단 및 관리에 필요한 빅데이터를 수집하고, 텍스트 정보를 대상으로 핵심단어의 단순빈도분석, 상대빈도분석, 동시출현분석, 상관성분석을 통해 핵심단어 및 주제를 추출하였다. 또한 추출된 핵심단어 및 정보를 분석하고 산포도, NetworkX, t-SNE 및 클러스터링 등의 다양한 시각화 처리를 함으로써 피부상태 진단 및 관리에 있어 이를 효율적으로 사용할 수 있도록 하였다.

시설물의 고령화로 인한 유지관리 비용을 줄이고 안전성을 확보하기 위해서는 시설물 유지관리 데이터를 활용하여 향후 시설물의 상태를 예측하고 이를 유지관리 의사결정에 활용하는 것이 중요하다. 이를 위해 본 연구는 XGBoost를 활용하여 다양한 유지관리 정보로부터 향후 시설물의 부재 상태를 추정하는 방법론을 제안함을 목표로 한다. 방법론의 유효성을 검증하기 위해 교량시설물을 대상으로 샘플 데이터를 구축하고, 차기 정밀안전점검 및 정밀안전진단 시 부재 상태등급 예측모델을 개발 및 평가했다. 예측모델의 성능 평가 결과, 주요 부재(바닥판, 주형, 교대/교각) 상태등급을 예측하는 데 준수한 성능을 보였다(평균 F1 score 0.869). 또한 개발된 예측모델의 실무적 활용 가능성을 실증하기 위해 FMS 유지관리 데이터 관리 기능과 주요부재 상태등급 예측 기능을 제공하는 테스트베드를 구축했다. 이를 통해 본 연구에서 구축한 샘플 데이터와 예측모델을 활용하여 시설물 관리자에게 유지관리 의사결정에 필요한 시설물 정보 및 시설물 상태 예측정보를 제공할 수 있음을 확인할 수 있었다. 향후에는 추가적으로 데이터를 수집하고 다량의 데이터가 축적된 경우 좋은 성능을 보인다고 알려진 딥러닝 알고리즘을 활용함으로써 예측 성능을 높일 수 있다. 또한 제안된 방법론을 터널, 항만 등 다양한 시설물에 적용하여 상태등급 예측모델을 개발할 수 있다.

Process Safety Management (PSM) system was introduced since 1996 and it makes voluntarily organizing and managing chemical accident prevention system by company itself that contributes to reduce the chemical accidents. However, large or small scaled chemical accidents had occurred frequently in these days. This trend is brought up the necessity to analyze and improve PSM system. In this study, it was conducted by the questionnaire survey and workshop for prevention of major industrial accidents in PSM sites in order to collect extensive opinions from all walks of life and identify overall operation condition. It was proposed to establish improvement plan of implementing condition assessment in PSM system. By results of the study, company's voluntary safety management will be induced by improved PSM system and management plan and it expects to prevent the major industrial accidents.

Purpose: This study aimed to identify the effects of the mother-medical staff partnership on mothers' condition management ability for children with chronic allergic diseases. Methods: A total of 109 Korean mothers caring for a child with a chronic allergic diseases, identified according to the allergic march, such as food allergy, atopic dermatitis, allergic rhinitis, and allergic asthma, were recruited from the pediatric department of a general hospital in Seoul through convenience sampling. Data were collected using structured self-reported questionnaires from August 1, 2017 to October 31, 2017. and analyzed by descriptive statistics and multiple regression using SPSS version 22.0. Results: The Mother-medical staff partnership had a statistically significant effect on mothers' condition management ability for children with chronic allergic diseases (p<.05). Among the general characteristics, satisfaction with nursing services had a statistically significant effect on mothers' condition management ability (p<.05). Conclusion: In conclusion, strategies to support children with chronic allergic diseases, as well as their caregivers, should consider the mother-medical staff partnership as part of a family-centered approach.

Indoor environments are usually less than optimal for the growth of ferns, especially in regards to the water condition. These studies were performed to investigate responses involved in causing growth of ferns and presume management plan against the water deficit under indoor conditions. The effect of air humidity and soil moisture on the ferns was examined in Adiantume raddianum and Selaginella kraussiana. Results of experiments are as follows; 1. Under a low humidity condition, having a 25-50% RH. ornamental value of ferns decreased much more than under a 90% RH. Under a low soil moisture, such as sand treatment, ornamental value of ferns also decreased. 2. Leaf chlorophyll content, water content and stomata situations increased as air humidity and soil moisture went up. 3. Even if air humidity and soil water were not enough for ferns growth, the extending of irrigation cycle was helpful. 4. Under extremely low air humidity conditions, some water management, namely, using water holding soil or extending of irrigation cycle was desirable. Other methods of increasing air humidity, including water instruments such as ornamental pools, waterfalls, or fountains, grouping plants together were also helpful. But spraying water on leaves increased injury to ferns growth because of excess evaporation from the leaves. Though these studies, we learn that ferns are susceptible to water condition such as air humidity, soil water and water management. If other environmental factos are maintained with optimal conditions, water condition plays an important role in ferns growth in indoor environments.

An outline of an Artificial Neural Network (ANN) model for bridge condition rating and the results of a pilot study are presented in this paper. Most BMS implementation systems involve an extensive range of data collection to operate accurately. It takes many years to effectively implement a BMS using existing methodologies. This is due to unmatched data requirements. Such problems can be overcome by adopting the ANN model presented in this paper. The objective of the proposed model is to predict bridge condition ratings using historical bridge inspection data for effective BMS operation.

The purpose of this study was to examine dimensions related to effective managerial actions in association with effects of resourcefulness personal and managerial communications and condition s for effective home management on the basis of managerial process. Including elements of managerial process conditions for effective home management were divided into the four factors performance-condition dichotomy timing high level and middle range. In conclusion first the managerial process for effective management can be classified into the four conditions related to each other. That was termed as 'conditions for effective home management' Second the most influential variables on conditions for effective home management were personal and managerial communication. The four conditions for effective home management need to include communicaion. Third resuorcefulness was a crucial factor in relation to home management resources division. It is recommedned that resuorcefulness needs to de elop managerial actions of housewives.
