This study identifies consumer needs and a pattern sensory evaluation of jacquard fabrics for raincoats using quick-drying-absorbing polyester. We investigate the consumer's consciousness and raincoat improvements. Twelve kinds of jacquard fabrics were developed for use in this study. Developed jacquard fabrics were assessed subjectively by 152 university students using a 7-point scale of 26 consumer needs and 31 pattern image sensory descriptors. Data were analyzed by SPSS. The major results were: There was a need for consumers to improve the front fastener type, cuff fastener, mesh patch position, and raincoat pocket position. The most important parameter to choose raincoat fabric was waterproof and the other parameters were vapor-porous/water repellent, design, color, fashionability, air-permeability and easy-put on/off. The pattern image sensibility of jacquard fabrics was explained by seven factors: gorgeous, simple, cute, futuristic, ethnic, feminine, and cool. A higher pattern preference was found in the jacquard fabrics of unique, sporty, natural, luxurious, and trendy images. The pattern preference was predicted at 45.3% with gorgeous, simple, pure, cute, futuristic factors. The correlation coefficient between the pattern image sensibility factor 1 (gorgeous) and pattern preference was 0.674 and with factor 3 (cute) was 0.416, and with factor 6 (cool) was 0.209. The 4 factors (gorgeous, simple, cute, futuristic) were selected as a significant pattern image sensibility that influenced preference.

BACKGROUND/OBJECTIVES: As the prevalence of chronic diseases has risen, the need for straightforward diagnostic tools for monitoring nutrition status to improve nutrition counseling and disease prevention has likewise increased. This study developed an easily usable dietary behavior pattern diagnosis checklist and investigated its correlation with dietary quality index. SUBJECTS/METHODS: A draft dietary pattern evaluation tool was generated by analyzing previous studies. The draft questionnaire comprised 61 questions for assessing dietary habits. A survey was administered to 320 adults (19 to 64 years old) using the dietary pattern evaluation tool and 24-hour-recall method between March and May of 2014 in Jeonbuk province and the metropolitan area. Principal component analysis with varimax rotation was performed to identify dietary behavior patterns. Nutritional analysis was conducted using CAN-Pro 4.0, and the Diet Quality Index-International (DQI-I) was calculated to assess dietary quality. The correlation between dietary pattern scores and DQI-I scores was also analyzed. RESULTS: The factor analysis resulted in a total of 34 questions mapped to four main dietary behavior patterns: "high fat and calorie" pattern (12 questions), "overeating/binge" pattern (nine questions), "dietary impulse" pattern (eight questions), and "unbalanced food intake" pattern (five questions). The four dietary behavior patterns were negatively correlated with DQI-I adequacy and total scores (P < 0.01). CONCLUSIONS: The dietary pattern evaluation tool developed in this study can be used to diagnose a client's dietary behavior problems and is available as a nutrition counseling tool in the field.

This study identifies the relation between recognition relatively deprivation and consumption patterns. The data used were the seventh Korea Welfare Panel Study (KOWEPS). The final sample of 1,597 households was selected based on several sampling steps standard weights suggested by KOWEPS were applied. The final sample was subdivided into household recognizing relatively deprivation (51.7%) and non-household recognizing relatively deprivation (48.3%) per level of subjective income and objective income. We derived six consumption patterns from the cluster analysis as per consumption ratio: transportation dominant consumption pattern, essential consumption pattern, other dominant consumption pattern, care attention consumption pattern, private transfer consumption pattern, and education dominant consumption pattern. The results of this study are as follows. The analysis of the determinants of recognizing relatively deprivation in regards to question one found that the household was likely to be relatively deprived when: the head of a household was older, a household had a dual income, children and more total assets then those assessed 1 year ago compared to household living conditions, result of comparing the consumption patterns difference between household recognizing relatively deprivation and non-household recognizing relatively deprivation indicated that household recognizing relatively deprivation was more likely to belong to the transportation dominant consumption pattern, other dominant consumption pattern, and private transfer consumption pattern. The multinomial logistic analysis conducted to understand the determinants affecting the consumption patterns of household recognizing relatively deprivation indicated differences in demographic characteristics, household-related variables, financial variables and perception of economic conditions.

This study was conducted to reproduce the Leg of Mutton Sleeve pattern of the ladies' costume of the 1890's for Korean women of the twenties who have the standard body type and the average size. Nineteen Leg of Mutton Sleeve patterns of the ladies' costume of the 1890's were collected and drawn to actual size. Nineteen Leg of Mutton Sleeve patterns of the ladies' costume of the 1890's were classified into three groups(S1~S3) by the pattern pieces and the bend of the lower part of the elbow line. The S1 was one-piece sleeve pattern and the lower part of the elbow line of S1 was not bent. The gathers volume of sleeve cap of S1 was smaller than S2 and S3. The S2 was one-piece sleeve pattern and the lower part of the elbow line of S2 was bent. The S2 pattern had typical characteristics of the Leg of Mutton Sleeve that the gathers volume of sleeve cap was large and the lower part of elbow line was tight. The S3 was two-piece sleeve pattern and the lower part of the elbow line of S3 was bent. The gathers volume of sleeve cap of S3 was similar with S2. The study patterns of three groups of the Leg of Mutton Sleeve which had the characteristics and the silhouette of the Leg of Mutton Sleeve pattern of the ladies' costume of the 1890's were designed like for Korean women of the twenties who have the standard body type and the average size through modifications based on the evaluation of dressing on two occasions. The study pattern of three groups of the Leg of Mutton Sleeve were evaluated to have the silhouette of the Leg of Mutton Sleeve of the 1890's and to fit Korean women of the twenties who have the standard body type and the average size with the sensory test.

마이크로 그리드 환경에는 변압기, 스위치, 에너지저장장치 등 많은 종류의 전력 설비가 존재하지만, IoT 기술의 발달에 따라 온도, 압력, 습도와 같은 센서 정보를 취득할 수 있는 기회를 제공하고 있다. 기존의 마이크로 그리드 환경에서는 IEC 61850 표준에서 정의하고 있는 MMS 등의 통신 프로토콜을 준용하여 전력 설비와 플랫폼 간 통합 운용되고 있다. 그렇기 때문에 IoT 데이터를 수용하기 위해서는 IEC61850 기반으로 구성된 데이터 수집 장치(FEP)에 IoT 데이터를 연계해 줄 수 있는 게이트웨이 기술이 필요하다. 본 논문에서는 마이크로그리드 운영 시스템 연계를 위한 IEC61850기반 IoT 게이트웨이 플랫폼 프로토타입을 제안하고자 한다. 게이트웨이 플랫폼은 IoT 프로토콜(MQTT, CoAP, AMQP) 인터페이스 모듈과 데이터베이스, IEC61850서버로 구성되어 있다. 데이터베이스의 경우, JSON 데이터를 저장하기 위해 오픈소스 기반의 NoSQL 데이터베이스인 Hbase와 MongoDB를 이용하였다. IoT 프로토콜을 검증하기 위해 라즈베리파이 아두이노 인텔 에디슨 SoC 기반 전력 IoT 디바이스 시뮬레이터를 이용하였고, IEC61850은 Sisco's MMS EASY Lite를 이용하여 IoT 프로토콜과 IEC 61850 프로토콜간의 상호호환성을 검증하였다.

본 연구는 사회복지학과 4학년생이 인식하는 사회복지사직에 관한 인식유형 연구이다. 본 연구의 목적은 사회복지사직을 준비하는 학생들의 교육에 필요한 기초 자료를 제공하고자 하였다. 이를 위해, 본 연구에서는 Q방법을 적용하여, 경상남도와 경상북도 4년제 대학교 사회복지학과 학생 30명을 대상으로 사회복지사직에 대한 주관적인 반응을 객관적으로 분석하였다. 연구결과, 사회복지학과 4학년 학생들의 사회복지사직에 대한 직업관 인식유형은 세 가지로 유형화될 수 있었다. 제 1 유형은 '직무비관적 현실회피형'으로 사회복지사직을 직무소진이 많고 업무량이 높다고 인식하며, 사회복지사직의 의미나 소명에 대해 비관적이다. 제 2유형은 '실천중심적 전문직추구형'으로 사회복지사직의 실천적인 측면을 중요시 여기며 전문직으로서의 사회복지사직을 추구하는 동시에 이를 위한 정책이나 제도에 의존하는 입장이다. 제 3 유형은 '가치지향적 자아실현형'으로 사회복지실천에 있어서 가치나 윤리의 필요성을 중시하며, 사회복지사직을 통한 자아실현을 중요하게 인식한다. 전체적으로 보아 사회복지학과 4학년 학생들의 사회복지사직에 대한 인식이 긍정적이지 못하며, 자아실현이나 전문직으로서의 자부심이 약한 것으로 나타났다. 이상의 결과를 통하여 볼 때 사회복지사직의 가치에 대한 교육이 더 필요하다고 본다.
