The purpose of this study was to evaluate nutritional adequacy and microbiological quality of foods served in day-care centers, and to provide basic information and guidelines for the development of computerized standardized recipes and microbiological quality control program. Assessment was conducted for four day-care certers selected from each of the four groups categorized in the basic survey. Nutritional balance and amount of consumption of the food was calculated and microbiological analysis was conducted. The results of the study showed the followings: the nutritional assessment of food served in day-care centers indicated that energy and nutrients contents of foods were below the recommended level (RDA/3), except the case of a university day-care center; the percentage of leftovers for soups and vegetables was high, but that for a la carte was low; fecal coliform was not found in any of samples, however, the number of coliform in the salted Korean radish and salad was higher than guideline for microbial acceptability; the number of coliform checked from the surface of the cutting board was higher than acceptable level in most day-care centers.

The system of School Meal Service Support Centers was established to support the supply of high-quality food ingredients for school meal services when the School Meal Service Act was amended in 2006. A case study was conducted to examine the operating effects, success factors, and major obstacles of a School Meal Service Support Center which was highly evaluated for its operational efficiency and customer satisfaction. Qualitative data were collected from eight stakeholders (two individuals each from the center, farms, schools, and distributors) through in-depth interviews in July 2013 and analyzed by using the thematic analysis method. The successful operation of the center helped to stabilize income and price among the stakeholders, increase ingredient quality, increase school meal reliability, reduce costs, and promote the consumption of agricultural products. Success factors were identified as the center director's commitment and insights, and the competitive operating system including fair operations, rational pricing, liberal consumer choice, total quality management, and partnerships with distributors. Major obstacles included a lack of diversity in supplied ingredients and a lack of administrative and financial support form the local government. The results can be used as baseline information to vitalize the system of School Meal Service Support Centers and increase the quality of school meal services.

Purpose: The purpose of this study was to examine the effects of a mobile application on quality of life, wellness, and preventive behaviors against dementia among older adults who use senior citizen centers. Methods: Seventy-two older adults who used senior citizen centers were allocated to an intervention group (n = 36) and a control group (n = 36). The experimental treatment involved a cognitive enhancement program for preventing dementia using a mobile application for 12 sessions over 6 weeks. Data were analyzed using the t-test, chi-square test, Fisher's exact test, paired t-test, and independent t-test. Results: The cognitive enhancement program based on a mobile application was effective for wellness (t = -3.87, p < .001) and preventive behaviors against dementia (t = -3.98, p < .001) for older adults who used a senior center. Conclusion: The mobile application-based cognitive enhancement program developed in this study is recommended as an effective intervention for dementia prevention in older adults.

과학영재교육 관점에서 성공지능 이론은 영재교육과정이 과학영재의 특성에 맞게 제시되고 있는지를 파악할 수 있는 수단이 된다. 이 연구의 목적은 초등 과학영재교육 교재에 제시된 발문 특성을 Sternberg의 성공지능 관점을 적용하여 분석하기 위한 것이다. 이를 위하여 교육청 영재교육원 2곳과 대학부설 영재교육원 1곳의 초등 과학영재교육 교재에 제시된 발문 각각 143개와 134개를 추출한 후, 이렇게 추출된 발문들의 구조적 특성에 차이가 있는지를 비교하기 위해 언어네트워크분석 방법을 활용하여 분석하였다. 그 결과는 다음과 같다. 첫째, 교육청 및 대학부설 영재교육원의 교재는 분석적 능력, 창의적 능력, 실행적 능력 등과 같은 성공지능을 균형 있게 반영하지 못하고 있었다. 둘째, 교육청 및 대학부설 영재교육원의 교재는 학생들에게 '문제 확인하기', '정보 표상하고 조직하기', '분석적 사고 촉진하기' 등 분석적 능력 영역을 집중적으로 요구하고 있었다. 셋째, 교육청 및 대학부설 영재교육원의 교재는 성공지능의 각 프레임 요소를 서로 유기적으로 연결되지 못한 채 제시되고 있다는 한계를 보였다. 과학영재들은 일반학생과 달리 학습속도가 빠르고 보다 복합적인 사고를 선호하는 특성을 보이기 때문에, 앞으로 과학영재교육 교재를 개발할 때에는 과학영재의 수준에 맞게 다양한 영역의 능력을 경험하고 통합적 사고를 촉진할 수 있도록 개발할 필요가 있을 것이다. 이런 측면에서 이 연구는 과학영재들의 맞춤형 교육지원을 위한 교재 개발을 위해 유용한 정보로 활용될 수 있을 것으로 기대된다.

Libraries and information centers are no different from any other institutions in our society. Today, their managers have to make many more decisions which have certain legal implications than before. The ignorance of the law on their parts can not be an acceptable excuse anymore, since. the consequences sometimes maybe quite serious. This paper outlines some important legal issues involved in the services and management of libraries and information centers. They are: constitutional rights on human knowledge activities: library act and it's related laws; censorship and right to know; information access and the protection of privacy: library services and copyright law; labor relations; protections of the people and properties of the institutions, etc. The laws are not static: rather, they change with the social, political and technological environments. The managers, as well as the staff members of libraries and information centers should be constantly updated with the changes in the field, in order to give the maximum service to the clients and to prevent any infringement of the laws, which may discredit their services and the institutions.

This paper attempts to propose the decision support model, which can be employed for 22 mail centers to improve their operational efficiency and competitive. This model deals with both DEA method and system dynamics model. DEA is a management tool aimed to determine relative efficiency of independent decision making unit. We measured the relative efficiency between mail centers using CCR model and tried to find the reason for inefficiency mail centers. Also, we introduced the system dynamics model to present the strategic policy for mail center to strengthen their efficiency.

We propose a series of methodologies that can evaluate relative efficiency of logistics units(centers) in three categories; managerial, cost, and operational efficiency. Inputs and outputs of logistics systems are first defined. Appropriate quantitative and qualitative measures for the three categories are then selected. Employed also are Analytic Hierarchy Process, Weighted Scoring Method, Stochastic Frontier Model, and Data Envelopment Analysis for the development of a comprehensive assessment scheme. Our scheme not only assesses the degree of relative efficiency of logistics units but also identify the sources of inefficiency in each unit The methodologies are applied to a large telecommunications company which operates 12 distribution centers nation wide. Relative efficiencies of the centers are compared using 1995-1997 performance data. Summarized are the level of efficiency of each distribution center for each of the three categories. The degree and sources of inefficiency of each distribution center are also discussed.

This paper addresses a network design problem in a supply chain system that involves locating both plants and distribution centers, and determining the best strategy for distributing products from the suppliers to the plants, from the plants to the distribution centers and from the distribution centers to the customers. This paper suggests a cooperative coevolutionary algorithm (CCEA) approach to solve the model. First, the problem is decomposed into three subproblems for each of which the chromosome population is created correspondingly. Each chromosome in each population is represented as a permutation denoting the priority. Then an algorithm generating a solution from the combined set of chromosomes from each population is suggested. Also an algorithm evaluating the performance of a solution is suggested. An experimental study is carried out. The results show that our CCEA tends to generate better solutions than the previous CCEA as the problem size gets larger and that the permutation representation for chromosome used here is better than other representation.

Nitrogen-Vacancy (NV) center in diamond has been an emerging versatile tool for quantum sensing applications. Amongst various applications, nano-scale nuclear magnetic resonance (NMR) using a single or ensemble NV centers has demonstrated promising results, opening possibility of a single molecule NMR for its chemical structural studies or multi-nuclear spin spectroscopy for quantum information science. However, there is a key challenge, which limited the spectral resolution of NMR detection using NV centers; the interrogation duration for NV-NMR detection technique has been limited by the NV sensor spin lifetime (T₁ ~ 3ms), which is orders of magnitude shorter than the coherence times of nuclear spins in bulk liquid samples (T₂ ~ 1s) or intrinsic ¹³C nuclear spins in diamond. Recent studies have shown that quantum memory technique or synchronized readout detection technique can further narrow down the spectral linewidth of NMR signal. In this short review paper, we overview basic concepts of nanoscale NMR using NV centers, and introduce further developments in high spectral resolution NV NMR studies.
