Construction while being an economic activity that provides facilities and infrastructure, it is beneficial to man in some aspects and detrimental in others. There have been environmental concerns related to construction activities globally which mainly focus on atmospheric emissions, depletion of natural resources and energy issues. This study was carried out to assess the impacts of construction activities on the environment in Iganga Municipality and to propose measures for their mitigation. The methodology included: review of relevant literature, observations of the general environmental effects of construction activities, focus groups and a survey conducted among construction industry role players to determine their perceptions and opinions regarding environmental impact of construction activities. The collected data was presented in tabular form and analysed by description of responses to questions. The study revealed that forests were the most greatly degraded due to high demand of timber for construction followed by wetlands degradation. The findings of this study will be useful to architects, designers and builders in order to carefully design buildings and other infrastructure that are environmentally friendly and sustainable. Construction materials and their mode of acquisition are harmful threats to the environment. There is need to reduce the consumption of these materials through recycling and reusing wastes to reduce on waste generation, use of virgin materials and the subsequent waste of energy used in new material production.
Objectives : The objective of this study was to examine the academic informationseeking behavior and demand of the oriental medical researcher and to create the base data for establishing a library environment providing a high-quality information service which would aid the activity of such researchers, Methods : We distributed a questionnaire to the one hundred professors of the college of oriental medicine on the method of acquisition of information data, the environment of the library belonging to the college, and the like. Results : $\circled1$ The main class using the academic information service of oriental medicine was revealed to be researchers having a career of 10 to 15 years who had a domestic doctorate in oriental medicine. $\circled2$ When accessing information, the primary information resource used was academic journals. $\circled3$ Of the data forms mentioned in the study, periodicals was used most in number of printed data; computer databases among non-printed data. $\circled4$ The purpose of using an information resource was for performing a research project. $\circled5$ The path of acquisition of information was usually through the materials in their possession. $\circled6$ The greatest difficulty in gathering information was first of all the lack of information owned by the library, and next a lack of time and insufficient knowledge of information search and use. $\circled7$ More than 90% of respondents on the necessity of an expert library answered as "necessary" or "certainly necessary", indicating that the foundation of an expert library is very urgent. Conclusions : This study is beneficial for researchers engaged in oriental medicine to activate the use of information and also it will form a base of data for researchers to establish an environment of expert library in oriental medicine.

In accordance with the KRR-1 & 2 decommissioning project, the decontamination and dismantling activities of the KRR-2 auxiliary facilities, radioisotope production facilities, were completed from Aug 2001 to Dec 2002. The auxiliary facilities were composed of the concrete hot-cell, lead hot-cells and several laboratories for the radioisotope production. The dismantling objects are home hoods, experimental desks, sinks, and contaminated inner facilities. For the purpose of the safe decommissioning activity, the method statements and working procedures were set up. The manpower of the total 20,933 man-hour was required and several dismantling equipments were also. The maximum surface contamination is: 9.24 Bq/$\textrm{cm}^2$ in removable contamination and 350,000 cpm in fixed contamination. The total amount of 62.146 Ton was raised as dismantled waste with kinds of the concretes, wood, steels, etc. The collective dose was evaluated as 0.33 mam-mSv during this period.
The transparisation technology for milk and milk products could be applied widely and very importantly to various determination because transparisation can economize the cost and increase with precision in the milk payment system. Component of butanone or Triton in transparisation solvent would inhibit the growth of bacteria and method. Enzymatic determination of leucocytes were proposed to evaluate milk quality as mastitis in the milk payment system, this can be easily applied to simplify automation of the determation with the lowest investment cost in milk pay system. The significance of this technique, it can be used in the quality control of raw milk and milk products, milk payment system, and programming of national dairy project. Transparisation technology is used in somatic cell counting by enzymic methods. The range of deviation for this method is 16% in 74 samples. But the deviation is increased to 20% when the Infoss method is used. It is affected by the percentage of epithelial cells and white blood cells in somatic cells from different animals and the stages of aging. NAgase activity has an obvious correlation with white-blood cells in milk. In the case of mastitis the white-blood cells is 90-95% in somatic cells in milk, it is showing greater precision in measuring the state of mastitis. In conclusion the enzymic method of somatic cell counting is a relatively simple and easy method of measurement and can be easily practiced. And the importance of this method is also worth utilizing for indirect counting of Somatic cells by use of synthetic substrates to NAgase. In the future, with the further development of the research in this field, it will b possible to automatize the measurement.
The aim of this study was to categorize and analyze the patterns of the observation type in the experiential learning through the science museum for elementary gifted students in science. Ten science-gifted students were included and analyzed in this study and during experiential learning in the science museum, the participants freely expressed their observation of their own languages and all observations and dialogue were recorded. The results are listed below. The cognitive aspect, especially question and response activity without their personal opinion, was the most frequently used item. Among the affective aspects, item for 'recommendation' was often used. In accordance to observation type, most participants overall observed single object independently of time. Also, participants mostly observed objects visually using qualitative method without manipulation. Therefore verbal interaction through question might have a positive effect on frequency and diversity of observation. Project learning, such as particular exhibition hall, exploratory time of concentration by students, or study paper will be capable of creating a effective observation learning in order to induce a variety of observation of science gifted students in the experiential learning through the science museum.
In Scandinavian countries, where the society experienced change of typical nuclear family structure and higher vocational activity rates of married women earlier than East Asian countries, cohousing scheme has been evolved as an alternative housing to reduce housework for working women, and to reduce loneliness of elderly people who stay in their own homes. They can promote active mutual relationship among residents in the community. Korean family structure has been stemmed to more like extended family, but the tendency to live independently from their married children is getting more and more common in new cohort of senior citizens who are active, healthy, economically stable and higher educated. Korea has been industrialized rather rapidly since 1970's and faces to many societal phenomena about quality of life for senior citizens. Introduction of alternative housing solution for these senior citizens is necessary in Korea. In this paper, Danish senior cohousing scheme, particularly, self-work model project is described about its design feature in accordance to site planning, common facility, and dwelling unit. Aiming to mutual support and more frequent social contacts among residents, self-work model cohousing scheme has different design concept from the service mode scheme. Information about design feature of senior cohousing was collected from the published data with drawings and from field survey to 10 exiting projects in Denmark. Of those, 5 projects were described as a case study. It, hopefully, could provide practical information for architectural design when establishment of senior cohousing schemes start in Korea in the near future.

The first category of Affective Domain objectives in Bloom's Taxonomy is about "Receiving". In it, the first subdivision listed is "Awareness" (Krathwohl, Bloom & Masia, 1964). Since these categories are intended to be hierarchical in ascending order of internalization, it is important that young learners be given ample opportunities in their learning experiences in class to be aware of positive values and effective life skills. This paper reports a feasibility study on the adoption of an integrative cognitive-affective learning approach in a primary school science lesson. 37 primary six students in a Singapore primary school were taught the concept of centre of gravity, including a hands-on activity to find the centre of gravity of an irregularly shaped cardboard by using a plumbline. After reviewing how a plumbline works, their teacher then led them into a discussion on the question "Who is the plumbline in your life?" a reference to identifying positive role models in their lives. From the transcript of the students' in-class sharing and their written responses to the question, it is clear that the integrative cognitive-affective learning approach did enable students to present their ideas and learning experiences in the affective domain quite readily. This conclusion provides a valuable lead to a follow-up project on whether students who are exposed to such integrative learning approaches will be more capable and more aware of identifying important positive social habits or values. If so, then the teaching of values in schools could take on a whole new dimension, that of borrowing students' learning energy in the cognitive domain to learn values and life skills in the affective domain.
We investigate the solar cycle variation of microwave and extreme ultraviolet (EUV) intensity in latitude to compare microwave polar brightening (MPB) with the EUV polar coronal hole (CH). For this study, we used the full-sun images observed in 17 GHz of the Nobeyama Radioheliograph from 1992 July to 2016 November and in two EUV channels of the Atmospheric Imaging Assembly (AIA) $193{\AA}$ and $171{\AA}$ on the Solar Dynamics Observatory (SDO) from 2011 January to 2016 November. As a result, we found that the polar intensity in EUV is anti-correlated with the polar intensity in microwave. Since the depression of EUV intensity in the pole is mostly owing to the CH appearance and continuation there, the anti-correlation in the intensity implies the intimate association between the polar CH and the MPB. Considering the report of Gopalswamy et al. (1999) that the enhanced microwave brightness in the CH is seen above the enhanced photospheric magnetic field, we suggest that the pole area during the solar minimum has a stronger magnetic field than the quiet sun level and such a strong field in the pole results in the formation of the polar CH. The emission mechanism of the MPB and the physical link with the polar CH are not still fully understood. It is necessary to investigate the MPB using high resolution microwave imaging data, which can be obtained by the high performance large-array radio observatories such as the ALMA project.

The molecular modification of antiepileptic drugs and direct synthesis of new drugs with the predetermined antiepileptic properties are perspective. New neurochemical attacking to solve the problem including prevention and inhibition of seizures seems to be related to ginsenosides and ginseng polypeptides. The main study based on the severity of febrile convulsions of rat pups has been done from the earlier investigations of antiepileptical action of ginsenosides between KGTRI and MSU (Chepurnov, Park et al., 1995) with different kinds of experimental models of epilepsy. From the cultured cell line DAN25 of ginseng root, the extracts of ginsenosides made in "BIOKHIMMASH" were studied by the project of preclinical anticonvulsant screening (Stables, Kupferberg, 1997). The inhibition of severity of convulsions, decrease of seizures threshold, decrease of audiogenic seizures in rats of different strains and normalization of cerebral blood flow (measured by hydrogen test) were demonstrated in rats after i.c.v., intraperitoneally and orally administration, respectively. The antiepileptical effects by the combination of compounds from ginseng; were compared with the iuluence of Rg1, Rb1, Rc and with the well known antiepileptical drugs such as carbamazepine, valproic acid. The base for the research is obtained by using the WAG/Rij strain (Luijtelaar, Coenen, Kuznetcova), an excellent genetic model for human generalized absence epilepsy. The improving action of gensinosides was effectively demonstrated on the model of electrical kindling of amygdala of WAG/Rij rats with genetically determined absences, and the influences of ginsenosides on the slow wave discharges have also been being investigated. The different characteristics of a kindling process exerted in the sex-different region of the amygdala and demonstrated that the level of sex steroids and content of neurosteroids in amygdaloid tissue can modify the development of seizures. The chemical structures of ginsenosides not only have some principal differences from well-known antiepileptical drugs but the Plant Pharmacology gives us unique possibility to develop new class of antiepileptic drugs and to improve its biological activity.
The purpose of this study was to explore the development of oriental health promotion project in korea. The study was performed from June 10, 1998 though June 30, 1998 by using questionnaires and the subjects were 208 in Taegu and Kyung-san city. The analysis methods were frequency, percentage, $x^2-test$ and ANOVA. The SAS/pc Program was used for the statistic analysis. The major findings are as followings; 1. The self-confidence of health was higher among male(2.59) than female(2.94). On the whole, the subjects studied have good health. Activity of daily life was medium. 2. As the subjects grow old, satisfaction level on health counselling with oriental doctors was high. Hospital and clinic covered 60-80% of the health assessment institutes and oriental hospital & clinic covered 10-18% of them. 3. As the subjects grow old was high the level of health promotion practice. On the whole, the level of health promotion practice was low. The physical exercise was highest covering 40% in the types of health promotion. 4. On the whole, the demand of oriental health promotion program was considerably high (male 2.06, female 2.49). The reason why the health promotion programs were necessary was necessary was the effectiveness of health promotion and the difficulty of self-practice. In the effectiveness of health promotion programs, the subjects were higher in oriental medicine than medicine. 5. In the validity level of physical constitution in the oriental medicine. the subject were high(3.48-3.80). But the necessity of the physical constitution change was medium.
