The present study was conducted as a part of the research on the investigation on daily life and consciousness of the longevous people in Korea. Surveys were carried out on their familial organization and the marriage life of longevous people in order to achieve the purpose of the research. The materials for 121 males and 258 females aged more than 80 were collected and analyzed from June to November 1985. The results are summarized as follows: 1. As for parents' mortality age of longevous people, 49.5% of them showed 'both above 70'(20.3%) and/or 'either father or mother above 70' (29.2%). Consequently, a significant difference was found between tile life span and inherent factor. 2. By the birth order of longevous people, '1st' had the highest figure of 41.2%. and decreased in the order of '2nd'(25.1%) and '3rd'(13.7%). It was observed that the more the birth order of longevous people preceded, the more life span of the aged increased. 3. Three to five persons in the number of brother3 and sisters comprised 57.6% of total longevous people surveyed. while 63.9% of them were revealed to have three to six in the number of offsprings.

This study examines the Korean Education Longitudinal Study 2005 7th-9th year data to analyze the university life of transfer students prior to their transferring by comparing them to that of non-transfer students. This study used two types of comparison groups: The first comparison group encompasses all who did not transfer and the second group was 1:1 matched sample of students who were enrolled in the same universities in the 7th year and were of the same gender. The 7th and 8th year experiences were compared, respectively. According to the result, transfer students in their previous universities compared to non-transfer students demonstrated higher grade point average, active class participation, and more interaction with faculty outside the class. On the other hand, these students demonstrated relatively lower satisfaction in university life, lower sense of belonging, and lower participation in student unions, campus events, and other student activities. They also tended to have less interaction with their colleagues. In other words, transfer students showed high competency and interests in academic activities like managing good grades and interacting with faculty but showed less interest in social activities such as interacting with peers and engaging in various campus activities. It is necessary to develope programs to help transfer students to adapt to school efficiently by utilizing the results of this study.

생산산업의 현대화저오ㄷ를 가름할 때 흔히 그 해당공정이 얼만큼의 비율로 자동제어장치가 되어 있느냐 하는것을 척도로 할 만큼 제어공학(Control Engineering)이 일반생산산업에 미치는 영향은 크다고 믿어진다. 이처럼 자동제어화의 인기가 높은것은 단순히 그렇게 함으로서 편리한 것 뿐만아니라, 그 기업의 수익을 증가시키기 때문일 것이다. 기업가의 입장에서 볼때, 자동제어의 결과로 (i)생산속도를 증가시키고, (ii) 규격치로부터의 오차를 줄임으로서 제품의 질을 향상시키고 (iii)생산원료를 절약하여 원가절감을 할 수 있는등의 이점이 있다. 이외에도 일상생활 환경에서 접하는 엘리베이터의 승강제어부터 우주선의 비행제어에 이르기까지 제어의 개념은 현대기술문명의 본질인 것이다. 본란을 통하여, 제어공학자들이 현재 사용하고 있는 설계방법과 앞으로의 발전경향에 대하여 간단히 소개하고, 아울러 학계 및 제어공학자들의 많은 관심을 모으고 있는 누연시스템(Tine-delay system)의 제어문제에 대하여 개략적으로 설명하기로 한다.

Secondary diseases that occur during the rehabilitation of breast cancer survivors are factors that can negatively change the physical and psychological state of the patient. The rehabilitation after treatment of breast cancer survivors is an important process to prevent cancer recurrence and increase the survival rate because a negative psychological state significantly impacts the long-term survival rate. This study identifies user requirements for the development of functional bras for mastectomy patients in Korea. Participants included 133 patients with one or more breasts removed due to breast cancer and an average age of 53.2 years (53.21 ± 7.57 years, minimum 33 years, maximum 69 years). Women in their 50s had the highest participation rate of 48.9%. Most maintained the same bra size before surgery; however, some experienced changes in bra size because they are not irritated by wounds caused by surgery. Therefore, it is important to pay attention to material when designing a functional bra because it can irritate the surgical site. Only about 41.4% of bras were worn by breast cancer patients because of price burden and lack of education, not complaints related to clothing design and wearability or body shape. Most purchases at hospitals or medical institutions require consultation with a specialist who provides information about a bra mainly at the hospital. The most important considerations when buying a breast cancer bra were size, fit and shape stability.

The recognition thresholds of sucrose, NaCl, citrate, caffeine, and MSG solution were determined and the effects of MSG on four basic tastes were also investigated by the sensory evaluation. The recognition threshold of sucrose was 0.451%, NaCl 0.01%, caffeine 0.005%, citrate 0.004%, and MSG 0.033%. When MSG was added to 10% sucrose solution, the intensity of sweetness significantly decreased by 0.8% MSG. The sweetness of sucrose indicated the decreasing tendency according to the addition of MSG. When MSG was mixed with NaCl solution, the intensity of saltiness significantly increased. With an addition of MSG to the citrate solution, sourness was suppressed. The bitterness increased slightly in a caffeine solution when mixed with MSG.

지난 135년(1880~2014년) 동안 지구온난화에 따른 기후변화로 지구의 평균 기온은 $0.85^{\circ}C$ 상승하였으며, 이는 수문현상에 영향을 미쳐 강우량 및 강우강도가 증가하는 경향성을 보이고 있다. 이처럼 기후변화로 말미암아 수문 현상의 변화에 따른 불확실성이 커져 물 순환 과정의 정확한 파악이 더욱 어려워지고 있다. 따라서 미래 안정적인 물 공급을 위한 수자원계획 수립 및 관리를 위해 기후변화를 고려한 물 수요 예측이 필요하다고 하겠다. 본 연구에서는 도시화에 따라 물수요가 변화하고 있는 안성천을 대상유역으로 선정하여 기후변화를 고려한 미래 물 부족량을 산정하고자 하였다. 이를 위해, 기후변화 RCP 8.5 시나리오를 이용하여 미래 강수량을 모의하였고, 준 분포 강우-유출 모형인 SLURP 모형을 이용하여 미래 유출량을 분석하였다. 미래 유출량을 토대로 정확한 물 수요 예측을 위해 통합수자원평가계획 모형인 K-WEAP 모형을 이용하여 소유역별 물수지 분석을 위한 네트워크 및 시나리오를 구성하였다. 또한 용수이용량(생활, 공업, 농업용수)의 과거자료를 활용한 선형예측함수식을 통해 장래 물 수요 추정량을 산정하였다. 물 수지 분석 결과, 안성천 유역은 인구 증가, 급격한 도시화로 인해 용수 이용량이 증가하고 있었으나 농업용수는 점차적으로 감소하고 있었다. 따라서 생활 및 공업 용수에 대한 수요를 충족하지 못해 미래 물 부족량이 증가하고 있는 것으로 확인되었으며, 본 연구에서는 물부족 해소를 위한 방안으로 광역상수도 확충과 제한급수를 제시하여 분석을 수행하였다.

The posthumanism, as it is discussed in several areas of the humanities, calls the modern humanist concept of autonomous subject into question. The scientific psychology has been since its birth as independent discipline at the 19th century a 'posthuman psychology' in the sense that there has been always humanistic approaches to humans as autonomous beings on the one hand, and natural-scientific approaches to humans as determined beings on the other hand. I have argued that the concept of autonomous subject makes still sense as a regulating principle of everyday life of purposive agents and as a conceptual framework for interpreting causal knowledges about humans. And I have argued that culture and cultural education should play an important role in reflecting on the meaning and rationality of sciences and technologies.

암을 제외한 대부분의 성인병은 혈액순환과 관련된 혈관계 질환들로 이들에 의한 사망 비율의 합은 암의 비율과 비슷하게 나타나 혈관계 질환의 심각성을 나타내고 있다. 혈전에 의한 혈관계 질환은 혈전용해제와 트롬빈저해제를 이용하여 치료하고 예방할 수 있으며, a-glucosidase 저해제는 당뇨병 예방과 치료에 이용할 수 있다. 예로부터 민간요법에서 다양하게 이용되어 왔던 반하를 성인병 치료와 예방에 관련된 기능성식품의 자료로 사용하기 위해 반하 열수추출물을 유기 용매로 분획화하고 분획물의 혈전용해활성, 트롬빈저해활성, 혈당강하효과를 측정하였다. 혈전을 직접 용해하는 활성을 측정하기위해 100 mg/ml의 농도로 준비한 시료액을 fibrin plate 방법을 이용하여 혈전용해활성을 측정 결과 hexane 층, chloroform 층, ethyl acetate 층, butanol 층에서는 활성을 나타내지 않았지만 물 층에서 만 0.8 plasmin unit의 높은 혈전용해활성을 나타냈다. 혈전의 형성을 억제하기위해 혈전형성의 필수 효소인 트롬빈의 활성을 저해하는 트롬빈저해활성을 측정하기위해 10 배 희석한 (10 mg/ml) 시료 용액을 이용하여 트롬빈저해활성을 측정결과 hexane 층에서 75.3%의 높은 트롬빈저해활성을 나타냈으며, ethyl acetate 층과 chloroform에서도 각각 43.3%와 39.7%의 활성을 나타냈다. 또한 탄수화물의 소화를 지연시킴으로서 소장에서 포도당의 흡수를 억제하여 혈관내 당의 농도를 조절하는 혈당강하제의 개발을 위해 준비된 조효소액(10 mg/ml)을 이용하여 a-glucosidase 저해활성을 측정한 결과 ethyl acetate 층과 hexane 층에서 각각 24.9%와 23.4%의 저해활성을 확인하였다. 따라서 반하의 hexane 층과 ethyl acetate 층과 물층은 혈전관련 혈관계 질환과 당뇨병 관련 기능성 식품의 개발 소재로 이용할 수 있을 것으로 기대된다. 특히 최근 질병 치료에 효과는 크지만 부작용이 동반되는 화학약품들 대신 활성은 조금 뒤지지만 부작용이 없는 생약을 이용하려는 경향이 커지고 있다. 따라서 오랫동안 민간용법에서 사용되고 있는 반하는 안정성이 확인된 장점을 갖고 있어, 식품재료나 기능성 음료에 이용할 경우 장기간 섭취가 가능해 혈관계 질환의 치료와 예방에 큰 효과를 가져 올 수 있을 것으로 기대된다.
