BACKGROUND: To investigate the dissipation patterns of 3 pesticides, azoxystrobin, difenoconazole and iprodione, on green garlic after field treatment pesticides were treated as foliar treatment by single application at recommended and double the recommended rates. METHODS AND RESULTS: Residue samples were harvested at 0, 1, 2, 5, 7 and 10 days post-treatment for azoxystrobin and 0, 1, 2, 5, 7, 10, 15 and 21 days post-treatment for difenoconazole and iprodione. After preparation the fortified samples were extracted and analyzed by gas chromotography-electron capture detector (GC-ECD) to determine the residue levels. Recoveries ranged from 87 to 109% for azoxystrobin, difenoconazole and iprodione at two different levels. The limit of Quantification (LOQ) values were 0.002 mg/kg for azoxystrobin and difenoconazole and 0.01 mg/kg for iprodione. CONCLUSION(S): Half-lives of azoxystrobin, difenoconazole and iprodione in green garlic after treatment were 1.2, 3.8 and 3.2 days at recommended and 1.4, 3.3 and 3.2 at double the recommended rate, respectively. Residue level of azoxystrobin, difenoconazole and iprodione in green garlic were below the maximum residue limits (MRLs) at 0 day, 0 day and 5 days, respectively. Therefore, these pesticide were considered that residues was satisfied to the requirement of domestic trade related to the consumer safety.

This paper examines the relationship between the locational patterns of global and domestic stores. Objective corporation for this research is the Daiei Inc., which is multinational retail corporation of general merchandise store industry. Used data are For the Customers and 1997 Annual Report published by the Daiei Inc. in 1997, and Worldwide Branch Location of Multinational Companies published by the Gale Researchy Inc. As a result it is recognized that the headquarters of supermarket companies are not necessarily established in the largest city of the store networks. In addition, the chani o stores does not always correspond to the economic territory area of a city or a regional urban system. Usually, supermarkets are established first one after another around the headquarter, so that the store network becomes intensive. Moreover, supermarket companies exhibit a tendence of expanding after having increased density of their stores in their indigenous regions. It seems that supermarket companies try to lay the foundation of their operation firmly on their indigenous regions, while they expand the store network into neighboring regions in order to enlarge their profits. This phenomenon appears more and less partly in the location of oversea purchasing offices. First oversea office location appears in neighboring countries whose headquarter is located in Japan. Another oversea office location is established in higher order city of another continent. Usally after the number of oversea offices increases in their headquarter's neighboring region, the oversea office network exhibits a tendency of expanding in another continents. in addition, network of oversea offices does not always correspond with world urban system. The location of oversea offices is formed, after internalization of supermarket stores was established in Japan. And when increasing rates of supermarket stores was low in Japan, number of oversea offices increased.

The purpose of weighting traffic management strategies is to reach strategic goal through intended and balanced implementations. The AHP is commonly used technique to derive perspective and strategic goals, and to give priorities to them in a organization. In this study, perspective and strategic goals are derived through surveys and interviews with staffs of a traffic management agency. And then, priority of perspective and strategic goals is performed through the AHP. In this study, three things were identified. Firstly, it was found weighting perspectives such as values for customers, future, activity, and performances were in sequence performed. The value for customers were ranked the first. Secondly, it was found increasing of customer- centric thinking and values of eco- friendly system are the highest weighting in strategic goal. Third, it was found increasing of customer-centric thinking is the most important in headquarters and regional headquarter. But, Values of eco-friendly system is ranked as the most important in opinion of branch office's staffs. It was also identified that depending on the working places, such as headquater and branch offices, the response differs.

This dissertation analyzed the satisfaction of corrective counseling programs for Korean domestic violence offenders. I conducted a survey of Korean domestic violence offenders scattered throughout the country. The survey period was between Mar Feb. 20, 2006 and Apr. 29, 2006. The specific objects of the survey are the 250 domestic violence offenders who got counseling in the Goyang branch office of the Justice Ministry-affiliated Uijeongbu Probation & Parole Center, Ansan Citizen Welfare Society's domestic violence counseling center, Korea Domestic Violence Counseling Center Association, Korea Women's Hot Line, Korea Family Law Counseling Center and its branch offices throughout the country, and the counseling centers commissioned by the court for domestic violence offenders. The study was based on a poll on 182 of the 250 offenders. The research result includes: First, the satisfaction of corrective counseling programs for offenders varies depending upon the age, educational background, location, job, income, and childhood abuse of offenders. In particular, the less experience of childhood abuse leads to greater effect of education. Second, of the types of corrective counseling programs for offenders, the satisfaction for those in couple counseling is the greatest. This is because couple counseling is more influential than individual in the professional education that helps to share and understand couple problems.

The physicochemical properties of solid wastes generated from seven highway service areas, four branch offices, and one construction site were analyzed in concert with air pollutants including heavy metals emitted from near-by small-scale incinerators. The amount of solid wastes generated from highway areas has been increasing with recent increases in the number of highways and passengers. Twelve incinerators examined in this study generally had capacity smaller than 100 kg/hr, most of which were equipped with cyclone for dust removal. It was seen that the concentrations of the gas-phase air pollutants (e.g., SO$_2$, NO$_{x}$, HCl and H$_2$S) were above the acceptable emission standards except one or two sites. CO concentrations at all incinerators were also higher due to incomplete combustion. In addition, particulate matters showed concentration six times higher at their maximum. The results of heavy metal analysis showed that the concentrations of Cu, Cd, and Ni satisfied the emission standards. whereas Pb at one site and Zn at five sites exceeded the standards. Cr measurement results indicated that 9 of 12 incinerators had higher values than the standard; especially one branch office showed nine times higher than normal concentration. In order to satisfy more stringent emission standards in the near future, it is necessary to install air pollution control system and to develop an intensified management plan.n.

Head louse infestation is a significant public health problem across the world, particularly among preschool and primary schoolchildren. This study investigated the trends of head louse infestation in the Republic of Korea over a 9-year period (2011-2019), targeting primary schoolchildren in 3 areas of Seoul, 4 other large cities, and 9 provinces. A survey was administered annually by the health staff of each regional office (n= 16) of the Korea Association of Health Promotion (KAHP). The branch offices of KAHP examined a total of 51,508 primary schoolchildren, comprising 26,532 boys and 24,976 girls. Over the 9-year survey, a total of 1,107 (2.1%) schoolchildren tested positive for adults and/or nits of Pediculus humanus capitis. The prevalence was 2.8% (133/4,727) in 2011-2012 and gradually decreased to 0.8% (49/6,461) in 2019 (P< 0.05). Head lice were found more frequently in girls (3.0%; 746/24,976) than in boys (1.4%; 361/26,532) (P< 0.05). In terms of geographic localities, the highest infestation rate, 4.7% (average prevalence over 9 years), was observed in southern Seoul (Gangnam branch of KAHP), whereas the lowest infestation rate, 0.7%, was seen in Gyeongsang (north and south provinces) and western Seoul. Although the prevalence decreased significantly during the 9-year period, head louse infestation remains a health and hygiene issue among primary schoolchildren in the Republic of Korea. Regular surveys along with health education are needed to further improve children's hair hygiene.

The mulberry variety, Jeonweon No. 1, has been cultivated in some parts of Ho-Nam District since the variety was selected at the Jeonbuk Provincial Silkworm Egg Production Station in the latter half of 1920s. However, the characteristics of the ariety have not been reported. Therefore, the cultivation experiment on the variety was carried out to investigate the characteristics of the variety at Jeonju and Suweon for four years from 1979 to 1982. 1. The mulberry variety, Jeonweon No. 1, belongs to the Morus alba L. and the sprouting stage is medium. 2. The branch growth of the variety was rather slow, however the number of branches was more and the posture of branches opened wide. 3. The rate of cold injury of shoot tips was a little high, but resistance to disease and the lodging of branches was weaker, compared with the Gaeryangbbong variety. 4. The annual yield of leaves of the variety per 10a was 1,474kg, 14% less than that of the Gaeryangbbong variety.

Experiments were conducted to know the ecology of injurious paddy field weeds, Scirpus hotarui and aneilema japonica in 1982-1983. Almost all emergences of the both species were on the soil surface in emergence depth. The vigorous growth stage was before Aug. 18, and the plant height and branch numbers were decreased and the days to flower were diminished by the shortday length treatment. A. japonica was not renewed by once cutting, but cutting S. hotarui on vigourous tillering stage was the most effective renew the growth and all of overwintered plants were renewed in emergence. The more these weeds emergence, the less rice yields.

Antibacterial activities of 33 antibiotics against Pseudomonas tolaasii causing the brown blotch disease on the edible mushroom Pleurotus ostreatus, were tested in vitro for the control of the disease. Tetracyclin, kanamycin, kasugamycin, and streptomycin showed strong antibacterial activity against P. tolaasii, having the minimal inhibitory concentration of 10, 10, 100 and 200ppm, respectively. These antibiotics showed similar control value of 72.9, 71.2, 68.1 and 62.7%, respectively when applied on the artificially infected mushroom beds. Mushroom yields in the tetracycline treated boxes were increased about 31.8% comparing to the control ones. Mycelial growth of P. ostreatus on the PDA supplemented with streptomycin and kanamycin were not affected, but were inhibited 10~20% and 40% with tetracyclin and kasugamycin treatment, respectively.
