One-person household is increasing by the growth of unemployment, divorce, aging in Korea. In particular, One-person households have rapidly increased around Farming & Fishing Regions. In this regard, this research aims to suggest the directions of housing supply for one-person households suitable for Farming & Fishing Regions by investigating the characteristics of one-person households in the social, economic, and physical aspects. This study found out that one-person households could be divided into two groups; one group lived in industrialized Farming & Fishing Regions and the other group lived in traditional Farming & Fishing Regions. For one-person households living in industrialized Farming & Fishing Regions, it is necessary to provide age-mixed residential sites where companies and manufacturers are condensed. On the other hand, for the one-person households living in traditional Farming & Fishing Regions, it in necessary to provide multi-person housing units for increasing the quality of life ofne-person households.

전국에 1인 전문가 체제의 박물관이 늘어나고 있다. 그러나 1인의 전문가가 박물관의 다양한 구성요소들을 콘텐츠화하여 운영하기 위해서는 시간과 자원이 부족하다. 본 논문은 1인 전문가 체제의 박물관이 운영되고 활성화되는 모델을 '공유'에서 찾고자 한다. '공유'는 박물관이 위치한 지역공동체의 요구를 수용하고 인적, 물적 자원을 확장하여 활용하는 방법이다. 기존의 박물관 협력망 사업은 재원 지원이 가능한 대규모 박물관이 주최가 되어 1인 체제 박물관을 지원해주는 방식으로 진행되었다. 기존의 체제가 박물관 지식의 전문성을 강조한 경쟁 원리를 기반으로 한다면, 지역과 박물관의 공유 방식은 소통을 기반으로 융 복합의 패러다임을 제시한다. 재원과 인력을 지역사회에서 충당하는 1인 체제 박물관은 자생(自生)이 가능하다.

유튜브에 대한 관심이 급증하면서 1인 방송시스템에 대한 수요가 증가하고 있다. 장비를 구축하는데 생기는 문제 중 가장 중요한 요소는 경제적인 부분이다. 따라서 본 논문에서는 스튜디오의 상용화와 경제성, 전문성의 상향평준화에 초점을 맞춘 스튜디오 구성을 제안해 누구나 손쉽게 1인 방송을 할 수 있도록 한다. 또한, 본 논문에서 제안한 새로운 1인 방송 시스템을 통해 '크로마키' 기능을 추가로 구현해봄으로서, 매번 같은 장소에서 촬영하는 1인 미디오 스튜디오의 특성을 보완해 1인 방송 제작자들이 더욱 다양한 컨텐츠를 만들어낼 수 있도록 한다.

The purpose of this study is to conduct research from qualitative aspects regarding the development of substantive design research for furniture brand and detailed development direction as single household has increased rapidly. In case of research method, the usability evaluation questionnaire was produced based on Honey Comb Model of Peter Morville. As a result, the single-person household including other household show preference for furniture for the one-man households and tend to purchase and use them. Nonetheless, it was found that places for sharing opinion and reselling the furniture are greatly lacking. Therefore, it is required to vitalize community market for the one-man household. And it is expected that this result of research provides useful implication concerning the single household as well as academic significance to offer primary information of furniture brand development-related research.

The number of one-person households in the modern society continues to increase, and is expected to increase steadily. In addition, one-person households had the largest number of detached house dwellings, while one-person households had the advantage of free living and free time. However, one-person households have concerns such as loneliness, health problems, safety, risk, and meal solutions, while detached house have problems such as living problems, maintenance, management, safety and risk, and lead to future concerns. This study was conducted in the following ways to improve the concerns of one-person households and the problems of detached house by applying smart home service to detached house. It was integrated through the investigation of concerns and grievances of one-person households and the case of preceding research on the problems of detached house. The latest technology trends of smart home services and the technologies currently developed and marketed were identified through prior research cases and literature surveys. Based on this, the smart home service list and application measures were derived to compensate for the concerns of one-person households and problems of detached house in applying them to smart home services.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Recently, the number of 'single-person household' is increasing rapidly. It brings about changes in the societal cultural aspect. Examples of television programs focused on their lifestyle provoked the societal attention as a important social agenda. This research investigated to figure out inherent ideologies in of tvN through Semiotic and Discourse analyses. As a result, predominant ideologies were revealed on the basis of representations of such single-person households. The authors also tried to find out how the media represent attitudes of single-person households and figure out how the media approach their ways of lives on bases of specific discourses and ideologies.

정렬 알고리즘에서 사용한 원소 간 비교횟수를 기준으로, 비교횟수가 많게 되는 순열을 최악의 인스턴스(worst-case instance)라 명명하고 이를 찾기 위해 유전 알고리즘(genetic algorithm)을 사용하였다. 잘 알려진 퀵 정렬(quick sort), 머지 정렬(merge sort), 힙 정렬(heap sort), 삽입 정렬(insertion sort), 쉘 정렬(shell sort), 개선된 퀵 정렬(advanced quick sort)에 대해서 실험하였다. 머지 정렬과 삽입 정렬에 대해 탐색한 인스턴스는 최악의 인스턴스에 거의 근접하였다. 퀵 정렬은 크기가 증가함에 따라 최악의 인스턴스 탐색이 어려웠다. 나머지 정렬에 대해서 찾은 인스턴스는 최악의 인스턴스인지 이론적으로 보장할 수 없지만, 임의의 1,000개 순열을 정렬해서 얻은 비교횟수들의 평균치보다는 훨씬 높았다. 본 논문의 최악의 인스턴스를 탐색하는 시도는 알고리즘의 성능 검증을 위한 테스트 데이터를 생성한다는 점에서 의미가 크다.

Excess application of paper mill sludge (PMS) in field can limit phosphorus uptake by crops because aluminum presented in the sludge can fix or adsorb available phosphorus which is necessary for crop growth. To investigate phosphorus (P) adsorption characteristics of PMS, we examined P adsorption maximum $(X_m)$ using Langmuir isotherm and P adsorption energy constant $(K_f)$ using Freundlich isotherm for PMS without alum, PMS with alum, and composted PMS with alum through a laboratory incubation test. The maximum P adsorption capacities were 800 ${\mu}g\;g^{-1}$ in soil, 47 $mg\;g^{-1}$ in PMS without alum and 61 $mg\;g^{-1}$ in PMS with alum. P adsorption capacity with alum treatment for PMS increased by 30%. That of PMS compost was 68 $mg\;g^{-1}$ and showed that composting increases 11% of P adsorption. Freundlich constant $K_f$ was 22 in check soil, while $K_f$ values in PMS without alum and in PMS with alum were 398 and 426, respectively. After composting, $K_f$ value of PMS compost significantly increased as 1,819. In conclusions, p adsorption capacity for PMS were increased by alum treatment or composting and therefore excess or continuous land application of alum-amended or composted PMS can limit P uptake for crops by reducing available P in sell.
