        KASI (Korea Astronomy and Space Science Institute) has developed an SLR (Satellite Laser Ranging) system since 2008. The name of the development program is ARGO (Accurate Ranging system for Geodetic Observation). ARGO has a wide range of applications in the satellite precise orbit determination and space geodesy research using SLR with mm-level accuracy. ARGO-M (Mobile, bistatic 10 cm transmitting/40 cm receiving telescopes) and ARGO-F (Fixed stationary, about 1 m transmitting/receiving integrated telescope) SLR systems development will be completed by 2014. In 2011, ARGO-M system integration was completed. At present ARGO-M is in the course of system calibration, functionality, and performance tests. It consists of six subsystems, OPS (Optics System), TMS (Tracking Mount System), OES (Opto-Electronic System), CDS (Container-Dome System), LAS (Laser System) and AOS (ARGO Operation System). In this paper, ARGO-M system structure and integration status are introduced and described.

        This study examined the understanding and use of information on nutrition labels based on one serving size among female consumers above the age of 20 in Seoul area. According to the survey, 69.9% of respondents were aware of the current system of nutrition labeling based on one serving size, and 51.8% of the respondents expressed their dissatisfaction with the system because the nutrition labels were difficult to understand or appeared unreliable. The nutrition label literacy of the consumers varied with respect to different packaging units. The respondents were likely to be less accurate in calculating the expected caloric intake when only portions of a multi-serving package were used. Initially 69.0% of respondents reported that they had read the nutrition label before purchasing a product but 91.9% of respondents said that they would check the label after learning how to read the label properly. It is very important to make consumers aware that the labels are very reliable sources of nutrition information. A public education campaign on the use of nutrition labels should focus on developing the consumers' ability and skills in using the label information when choosing foods.

        농약중심의 해충방제에서 벗어난 환경과 건강을 중시한 친환경농업의 실현 을 위해 새로운 우수 토착 천적의 발굴 필요성이 증대되고 있다. 따라서 본 연구에서는 딸기, 콩류 등 광범위한 농작물의 해충으로 알려진 담배거세미나 방(Spodoptera litura (Fabricius))의 유충을 공격하는 내부기생성 천적인 예쁜가 는배고치벌(Meteorus pulchricornis (Wesmael))을 발굴하여 실내에서 성충 산란 성, 수명 등을 조사하였다. 사육환경은 24L, 25℃, 50±10% RH 조건하에서 성충 수명과 산란성을 조사 하였다. 성충(암컷) 수명을 조사한 결과 25±3일이었다. 산란성은 성충 전 기간 중 초기에는 산란률이 낮았으며, 주로 중․후기로 접어들수록 산란된 개체수 가 증가되었다. 기생률에 대한 결과는 현재 자세히 검토 중이다.

        목적 : 본 연구는 일부 병원의 작업치료사를 대상으로 직무특성, 스트레스, 만족도를 파악하고, 직무만족도에 영향을 미치는 요인들을 분석하기 위한 것이다. 연구방법 : 2005년 11월 5일까지 대한작업치료사 협회에 등록된 임상작업치료사로서 일반적 특성, 직무특성, 직무스트레스, 직무만족도를 포함한 총 63문항의 구조화된 설문지를 가지고 자료 수집을 하였으며, SPSS 프로그램을 통해 일반적 특성과 업무에 따른 직무만족도 및 하부요인 만족도의 차이를 알아보기 위해 t-검정, 직무요인은 ANOVA검정, 직무만족도에 영향을 미치는 독립변수들을 평가하기 위하여 위계적 다중회귀분석(hierarchical multiple regression)을 실시하였다. 결과 : 업무만족도는 1일 치료 환자수가 적을수록, 환자치료에 더 많은 시간을 사용할수록, 직무자율성 요인의 스트레스가 낮을수록 높으며, 소아․청소년을 담당하는 치료사의 업무만족도가 높았다. 직업만족도는 1일 치료하는 환자의 수가 적을수록, 동료수가 2~4명인 경우는 높았지만, 연령이 낮고, 조직체계 요인의 스트레스가 높을수록 낮았다. 보상 및 기회만족도는 남자작업치료사, 연령대가 30~34세 이상, 기혼자, 1일근무시간이 8시간이하, 근무기간이 5년 이상, 급여가 월 200만원 이상의 경우 높았다. 전체만족도는 연령이 30~34세 이상인 경우, 1일 치료 환자수가 적을수록 높았고, 연령이 낮을수록 낮았다. 직무스트레스 요인과 직무만족도의 상관관계를 보면, 모든 직무스트레스 요인은 직무만족도와 역상관관계를 보이며, 특히 직무자율성 결여, 관계갈등, 조직체계 및 보상부적절 항목은 모든 만족도와 통계적으로 의미 있는 역상관관계를 보여주었다. 결론 : 직무만족도를 높이기 위하여 관계갈등과 조직체계의 스트레스 요인을 줄이고, 직무 자율성을 높이는 것이 중요하며, 이를 위하여 작업치료사들의 업무권한 및 자율성을 개선시키고, 조직 내 구성원들 간의 관계개선 및 의사소통을 원활하게 하고 복지후생 및 인사체계의 합리성과 관련된 조직문화 개발, 그리고 성과급이나 교육의 기회제공과 같은 보상과 관련된 제도적 장치가 필요하다고 하겠다.

        The general composition like moisture content, and the physical and sensory characteristics of the steamed rice cake added with powder of roots of balloonflowers were as follows. The moisture content in the roots was 4.13±0.01%, crude protein 9.24±0.11%, crude fat 3.07±0.04%, crude fiber 33.82±0.01%, and crude ash 8.16±0.02%. The moisture content of the cake was decreased with increase of the root’s powder added. In physical characteristic, the hardness of the cake was increased with increase of the powder. The control cake was the highest in the cohesiveness. The springiness tended to be increased with increase of the powder. The gumminess was higher with increase of the powder, being 530.33% in the control and 284.44% in the sample with 12.0% powder added. The adhesiveness was decreased with increase of the powder. The color change was significantly decreased with increase of the powder. With increase of the powder, the value a was decreased, while the value b showed to be increased. In a sensory test, the favorite degree to color, flavor, bitter taste, moistness, soft-ness and overall acceptability was measured to get the follow result. To color, the lot with 6% of the balloonflower powder added showed the highest accept-ability with the same highest result also to flavor and bitter taste. The moistness and the softness were revealed as the highest at the control, and the chewiness was also highest at the lot with 3% of the powder added. The overall acceptability was highest as 5.75 at the lot with 6% of the powder added, coming out to be higher in order of the 3% added-lot, the control, the 9%-lot and the 12%-lot.

        This research was performed with the subject of 111 offices in a chemical plant of Korea. Airborne concentration level of carbon dioxide, carbon monoxide, formaldehyde and total suspended particulates in the office rooms were measured along with temperature and relative humidity. Simultaneously, general characteristics and subjective health symptoms of 500 office workers were investigated through a questionnaire consisting of the five point weighting method : 0 = not at all, 1 = a little bit, 2 = moderately, 3 = quite a bit and 4 = extremely. Results showed that the mean values for temperature and relative humidity in investigated office rooms were 22.2℃ and 34.3%, respectively. The concentrations of formaldehyde, PM10, carbon dioxide and carbon monoxide were 0.17 ppb, 28.8 ㎍/㎥, 0.95 ppm and 424 ppm, respectively. 56.4% of all the workers investigated replied with a sense of fatigue or weariness (mean=2.23), drowsiness or languidness (mean=2.22), sneezing (mean=2.11) and ophthalmia oreye fatigue (mean=2.07). Female workers, non-smokers, non-drinkers, workers who do shift more than nine hours a day, and workers in poor health experienced more subjective symptoms than other workers (p<0.05). Subjective symptoms of office workers were significantly associated with the following items of office characteristics: the purchase date of office equipment, the change of office furniture, the use of paint, smoking in the office, ventilation condition, the use of an individual air-conditioner, the use of a fax machine, the degree of office repair, the proportion of workers per office, the degree of satisfaction in office environment, and the operation hours of the air-conditioner. Also, subjective symptoms were positively correlated with indoor environmental factors such as relative humidity, carbon dioxide level, level of PM10, and formaldehyde (p<0.05). In conclusion, office characteristics and air quality in a chemical plant affected subjective health symptoms of office workers. Thus, in order to improve the health of workers, to enhance work efficiency, and to establish a better office environment, air quality control in office rooms by optimal ventilation, adequately occupied number of workers in one office, and maintenance of office equipment should be fulfilled thoroughly. keywords:Air quality, Subjective health symptom, Formaldehyde, PM10, Carbon monoxide, Carbon dioxide
