Acidic air pollutants were collected to characterize indoor air quality at a private house in Seoul during the spring period. All indoor and outdoor samples were measured simultaneously using an annular denuder system. The data set was collected on twelve different days with a 24-hr sampling period in April and May 1997. The chemical species measured were HN $O_3$, HN $O_2$, S $O_2$ and N $H_3$in the gas phase and P $M_{2.5}$ (dp 2.5 ${\mu}{\textrm}{m}$), S $O_4$$^{2-}$, N $O_3$$^{[-10]}$ and N $H_4$$^{+}$ in the particulate phase. Indoor concentrations of HN $O_2$, N $H_3$, and P $M_{2.5}$ were greater than outdoor levels. However, indoor concentrations of HN $O_3$, S $O_2$, N $O_3$$^{[-10]}$ and N $H_4$$^{+}$ were less than those found from outdoors. In the case of S $O_4$$^{2-}$, the indoor and outdoor concentrations were similar. Indoor concentrations of P $M_{2.5}$ , S $O_4$$^{2-}$ and N $O_3$$^{[-10]}$ were dependent upon the outdoor concentrations. A tracer-gas decay technique with sulfur hexafluoride (S $F_{6}$ ) as the tracer gas was used to estimate the air exchange rate of a private home in the spring. The average air exchange rate was computed to be 2.87 h $r^{-1}$ .X> .

This paper presents a robotic agent design and application in the ubiquitous intelligent space. We set up an experimental environment with Bluetooth host, Bluetooth client, furniture and home appliance, and robotic agents. First, the agents basically performed patrol guard to detect unexpected penetration, and to keep home safely from gas-leakage, electric leakage, and so on. They were out to patrol fur a robbery while navigating in a living room and a private room. In this task, we used an area-based action making and a hexagon-based Q-learning to control the agents. Second, the agents communicate with Bluetooth host device to access and control a home appliance. The Bluetooth host offers a manual control to person by inquiring a client robot when one would like to check some place especially. In this exercise, we organize asynchronous connection less (ACL) between the host and the client robots and control the robot maneuver by Bluetooth host controller interface (HCI).

The purpose of this research was to investigate the economic status and problems of the middle aged apartment-residents in Seoul as a part of collaborative study on family issues of them. The sampling households were divided into Kangnam and Kangbuk area according to their residential location and upper-middle and lower-middle groups according the size of the apartment unit. The analysis of this research was specially focused on the latter division. The data were collected from 307 fulltime housewives with at least one child in a middle or high school. This data were gathered from the structured questionnaire. The major findings of this research were as follows: 1. The significant differences between upper-middle and lower-middle groups were showed in such areas as household income, monthly living expenses, household assets and savings. 2. The most serious economic problem was the private education expenses in both groups. 3. The economic satisfaction of the group in the Kangbuk area was a little higher than the group in Kangnam area.

Though weight manufacturing has in national gross production is decreasing, it has still a decisive role in economic growth of Korea, and foreign competitiveness of manufacturing has a great influence on our whole economy. Therefore, as this study speculates export competitiveness of manufacturing item by item, the results can be used for selection of strategic export-oriented products. The results of the analysis are summarized as follows: first, products that are found as competitive through analysis of trade specialization indexes are plastic, rubber, fabric, home electronic appliances, computers, communication equipment, automobiles and their spare parts. Second, electronic-electric industry such as semi-conduits, communication equipment, home electronics, computers was decided as advantageous through analysis of comparative advantages at present, while paper, print and publishing, and leather industries were classified as comparatively disadvantageous. Its political implications are presented as follows: Private corporations should develop more advanced technology and government should give more support to secure export competitiveness of manufacturing toward America. Governmental policies should be prepared to induce consistent and daring investment to technology-intensive products for export products with high-added value.

The purpose of this survey was to find out the actual conditions of living and housing needs of three generation family in the sharing apartment houses in Sang-Gye area. 1. General family type was one which is living with single parent (female), middle-aged couple and their children togeter. 2. Their main mobility to move in this houses was because of the special design of sharing apartment houses. 3. Most of actual dwelling activities of old parents and middle aged couple were performed in condition of space-integration except a few activities. 4. The "Space-compromise type" was proved as the most ideal type of three generation sharing house in our country. In which, private spaces (such as bed rooms and bath rooms) are planned to be used seperately, public spaces (such as living room and dining room) together. 5. It would be better if massionette type was taken in the case of more than 30 pyung (net area).net area).

The purpose of this study was to investigate the relationship between the father's emotional expressiveness and verbal controls, and his children's social competency depending on gender. Subjects were 156 five-year-old children and their fathers in 4 private kindergarten in Gyeongi province. The data obtained were analyzed by frequencies, percentiles, means, standard deviations, Cronbach's alpha, t-test, and Pearson's correlations. The major findings of this study were as follows: 1) A significant difference was found between the children's gender in terms of children's external behavioral problems in social competency. 2) There was a negative correlation between the fathers' negative emotional expressiveness and their male children's social competency. 3) There was a negative correlation between the fathers' imperative control under verbal controls and their male children's social competency.

Multiple features of infant day-care are explored, including age of entry, quantity, quality and stability of day-care. And relative contribution of day-care and family factors on maternal behaviors are examined. Data were gathered from 299 mothers who have infants aged under 36 months using self-report questionnaires. Results show that more than 40% infants enter day-care before 6 months of their life and about 85% of infants have far more than 30 hours of care a week. Half of the infants experience different day-care arrangements more than once. Compared to the other types of day-care, frequency of day-care arrangement change and quality of care are highest in private child-care centers. A series of Hierarchical regression results reveal that quality of day care is negatively related to mothers' control behavior whereas positively related to mothers' responsive behavior. But in general, family and child characteristics play a greater role in mothers' parenting behaviors than infant day-care characteristics.

우리나라에 유통업체상표(Private Label)가 도입된 지 10년이 넘었음에도 불구하고 유통업체 상표에 대한 대부분의 연구는 소비자 관점에서 진행되어져 왔다. 본 연구는 유통업체상표를 소비자 관점이 아닌 제조업체의 관점에서 바라본 연구로, 제조업체의 유통업체상표 생산에 영향을 미치는 내외부적 요인들에 대해서 자원기반이론과 S-C-P Paradigm의 통합적인 연구모형인 전략적 시장관리 관점을 제시하였다. 연구결과를 보면, 제조업체의 마케팅 역량이 높을수록 전체 매출에서 유통업체상표가 차지하는 매출이 적은 것으로 나타났으며, 마케팅 역량에는 제조업체 브랜드명성, 마케팅 투자, 제품포트폴리오 등이 영향을 미치는 것으로 나타났다. 또한 제조업체의 마케팅 역량과 유통업체 상표 생산 간의 관계에는 제조업체의 경쟁강도가 조절효과를 미치는 것으로 나타났는데, 이는 일반적으로 마케팅 역량이 높은(낮은) 기업일수록 전체 매출에서 유통업체상표가 차지하는 비율이 낮지만(높지만), 이러한 기업들 중 경쟁강도를 낮게 지각하는 제조업체의 전체매출 중 유통업체상표가 차지하는 매출은 경쟁강도를 높게 지각하는 제조업체들에 비해 상대적으로 높게 나타났다. 이러한 연구결과를 바탕으로, 본 연구는 유통업체상표 생산에 대한 이론 및 실무적인 시사점을 제시하고 있다.
