  • This study was carried out to investigate residual characteristics of insecticide acetamiprid in asparagus under greenhouse condition from July to August and consequentially to obtain basic data for guideline on safe use of this pesticide in asparagus. Residues of acetamiprid in young stem of asparagus before and after removing foliage were analyzed from samples harvested at 0, 1, 3, 5 and 7 days after single application before harvest. As a result, residues of acetamiprid in young stem of asparagus before and after removing foliage at 0 day were 0.27 mg/kg and 0.14 mg/kg, respectively, which were higher than tentative limit (0.1 mg/kg). However, 3 days later residues of acetamiprid were lower than the tentative limit, representing 0.08 mg/kg and 0.03 mg/kg in the asparagus before and after removing foliage, respectively. Acetamiprid was undetectable in both samples at 5 days since the concentrations were less than detection limit (0.02 mg/kg) in this study. In summary, the half-life of acetamiprid in asparagus regardless of removing foliage was quite short under greenhouse condition from July to August, in the range of 1-3 days, and single application of acetamiprid water dispersible granule in/on asparagus at 7 days before harvest would have no problem on safety issues about pesticide residue. This result might be basic information to construct guideline for safe use of acetamiprid in asparagus.

  • Character industry is not only knowledge-based industry chiefly with copyrights but also motive power for creative economy to take a role functionally over the fields of industries because it has industrial characteristic as complement product to promote sale value in manufacturing industry and service industry and increase profit on sales. Since 2003, the national policy related to character has aimed to maximize effect among connected industries, extend its business abroad, enforce copyrights through the improvement of marketing system, develop industrial infrastructure through raising quality of character products. With the result of this policy, the successful cases of connected contents have been crystallized and domestic character industry has stepped up methodically since 2007. It is needed to reset the scales of character industry and industrial stats because there are more know-how of self industry promotion and more related characters through strategy of market departmentalization starting with cartoon, animation, games, novels, movies and musicals. Especially, The Korea government set our target for 'Global Top Five Character Power' since 2009 and has started to carry out to find global star characters, support to establish network among connected industries, diversify promotion channels, and develop licensing business. Particularly, since 2013, There have been prospered the indoor character theme park with time management just like character experimental marketing or Kids cafes using characters, the demand market of digital character focusing on SNS emoticon, and the performance market for character musical consistently. Moreover, The domestic and foreign illegal black markets on off-line have been enlarged, so we need another policy alternative. To prepare for the era of exploding character demand market and diversifying platform, it is needed to set up a solid strategy that is required the elements of policy changes in character industry to vitalize character industry and support new character design and connected contents. the following shows that the elements of policy changes related to the existing policy, the current position of market. Nowadays, the elements of policy changes in domestic character industry are that variety of consumers in the digital character market according to platform diversification, Convergence contents of character goods for the Korean waves, legalization of the illegal black contents market, and controling the tendency of consumers in departmentalized market. This can help find the policy issue entirely deferent with the existing character powers like US, Japan or Europe. In its final analysis, the alternatives are the promotion of models with contract copyrights of domestic and foreign connected contents, the diversification of profit models of platform economy, the additive development of target market related to enlarging the Korean waves, and the strategy of character market for the age-specific tendency according to developing character demand market.

  • The general objective of this research is to study behavioral pattern of health care utilization and to measure the level of utilization of the traditional medicine. The specific objective is to study utilization pattern and content of folk medicine which is the indegenous medical technology recognized part of traditional medicine. This research was under taken to generate valid information that will provide basis data for formulating general direction for health education activities and for designing service package for general population. A social survey method was employed to obtain required information for the research activities, The survey field team consisted of 20 surveyors who all participated is an intensive 2 day training course. A total of 3091 households were visited and interviewed by the field team during the period 7 September to 6 October 1987. The major findings obtained from the information collected by the field survey are as follows ; 1) General characteristics of the study households 2562 households out of 3091 households visited were selected for final data process, 80.2 of the selected households were nuclear families ; 17.4%, extended families ; others 2.4%. Only 4.3 percent of the study population in the urban households indicated "no schooling" whereas 14.2% of the rural household members falls within this category. Study population in the urban areas are more protected against diseases by the national medical insurance system than those in rural areas. In their self appraisal of living standard, those who responded with low group are 39.6% and 50.3% respectively by urban and rural households. 2) Morbidity status Period prevalence rate for all diseases during the preceding 15 days before the date of the household interview v as 243,0 per 1,000 study population. For cases with the illness duration of within 15 days, the initial points of medical entry were diversied ; 56.9%, drug stores ; 30.9%, clinics and hospitals ; 4.6% folk medicine ; 1.7% clinics of Korean oriental medicine. Among the chronic case; with illness duration of over 90 days, 34.6% of these people utilized clinics and hospitals of modern medicine ; 31.6%, drug stores ; 18.6% clinics of Korean oriental medicine ; 6.8% folk medical techniques. Noticeable is the almost ten fold increase from the mere 0.9% in the utilization of Korean oriental medicine, whereas in the utilization of folk medicine, it is short of two-fold increase. 3) Folk medicine and its utilization Households that use folk medicine for relief and care of signs and symptoms commonly encountered in daily life, number 1969 households, which accounts for 76.9% of all the study households. This rather high level use of folk medicine is not different from rural to urban areas. The order of frequency of utilizing folk medicine among the study people are : the highest 14.3% for the relief of indigestion ; 8.6% for burns ; 5.1% for common cold ; 4.7% for hiccough ; and 4.2% for hordeolum. A present various procedures of folk medicine is being used to relieve all kinds of symptoms. 192 symptoms are identified at present. The most frequently used procedures of folk medicine appear to be based either on principles of the Korean oriental medicine or of scientific knowledge. Based on these survey findings, proposals for utilizing folk medicine are as follows First, this survey's findings will be feed back to both on the job training and on the spot guidance of community health practitioners, public health nurses and other peripheral work force in the health field, who are in daily contacts with community. This feed back will assure that the health personnel carry out their health education and information activities that are based on the utilization pattern of folk medicine as found in the survey result. Second, studies will be soon implemented that are designed to measure the efficiency and potency of these procedures and to improve these procedures of folk medicine were most frequently used by the community. Third, studies will continue to systematize medicinal plants and skills of Korean oriental medicine that are easily available at minimal cost in daily life for the prevention of diseases and management of emergency cases.

  • The private security industry in Korea has rapidly proliferated. While the industry has grown quickly, though, private security officers have recently been implicated in incidents involving violence, demonstrating an urgent need for systematic reform and regulation of private security practices in Korea. Due to its quasi-public service character, the industry also risks losing the public's favor if it is not quickly disciplined and brought under legitimate government regulation: the industry needs professional standards for conduct and qualification for employment of security officers. This paper shares insights for the reform of the Korean private security industry through a study of the licensing and training requirements for private security businesses in the United States, mainly focusing on the Private Security Officer Employment Authorization Act (hereinafter the PSOEAA) and the California system. According to the PSOEAA, aspiring security officers shall submit to a criminal background check (a check of the applicants' criminal records). Applicants' criminal records should include not only felony convictions but also any other moral turpitude offenses (involving dishonesty, false statement, and information on pending cases). The PSOEAA also allows businesses to do background checks of their employees every twelve months, enabling the employers to make sure that their employees remain qualified for their security jobs during their employment. It also must be mentioned that the state of California, for effective management of its private security sector, has established a professional government authority, the Bureau of Security and Investigative Services, a tacit recognition that the private security industry needs to be thoroughly, professionally, and actively managed by a professional government authority. The American system provides a workable model for the Korean private security industry. First, this paper argues that the Korean private security industry should implement a more strict criminal background check system similar to that required by the PSOEAA. Second, it recommends that an independent professional government authority be established to oversee and enforce regulation of Korea's private security industry. Finally, this article suggests that education and training course be implemented to provide both diverse training as well as specialization and phasing.

  • The aim of this study is to investigate the microbial contamination assessment of raw Jinmichae to cook and to establish its control. Three kinds of Korean Jinmichae products(K1, K2, K3) and three kinds of imported Jinmichae products(Chile: F1, Peru: F2, Mexico: F3) were collected from markets and department stores in Seoul and Gyeonggi-do. The results were as follows; Aerobic mesophilic bacteria in raw Jinmichae(F2) was detected $7.20{\times}10^7$ CFU/g, which exceeded the acceptable standard level, $1.0{\times}10^6$ CFU/g. The rest of raw groups fell up to $1.0{\times}10^3{\sim}1.0{\times}10^4$ CFU/g. Aerobic mesophilic bacteria were detected in blanched and fried Jinmichae groups. Boiled Jinmichae group did not exceed the acceptable standard level of $1.0{\times}10^6$ CFU/g. However, all the fried groups exceeded the level. E. coli were detected in raw Jinmichae but it was able to be controlled by blanching. Unlike this, E. coli was not completely controlled by roasting for 20 seconds relative to 40, 60 seconds. S. aureus were effectively controlled by boiling, however, it was not controlled by roasting. After roasting Jinmichae for 60 seconds, S. aureus were detected in the half of all groups. In this study, Jinmichae were found to be favorable one of side dishes in school meal service. Jinmichae can be contaminated by microbial pathogens such as S. aureus, E. coli, etc. Therefore, further studies are needed to monitor microbial pathogens and to provide their control.

  • A review on the papers published in the Korean Journal of Air-Conditioning and Refrigerating Engineering in 2000 and 2001 has been done. Focus has been put on current status of research in the aspect of heating, cooling, ventilation, sanitation and building environment. The conclusions are as follows. (1) Most of fundamental studies on fluid flow were related with heat transportation of facilities. Drop formation and rivulet flow on solid surfaces were interesting topics related with condensation augmentation. Research on micro environment considering flow, heat, humidity was also interesting for comfortable living environment. It can be extended considering biological aspects. Development of fans and blowers of high performance and low noise were continuing topics. Well developed CFD technologies were widely applied for developing facilities and their systems. (2) Most of papers related with heat transfer analysis and heat exchanger shows dealt with convection, evaporation, and channel flow for the design application of heat exchanger. The numerical heat transfer simulation studies have been peformed and reported to show heat transfer characteristics. Experimental as well as numerical studies on heat exchanger were reported, while not many papers are available for the system analysis including heat exchanger. (3) A review of the recent studies on heat pump system shows that performance analysis and control of heat pump have been peformed by various simulations and experiments. The research papers on multi-type heat pump system increased significantly. The studies on heat pipe have been examined experimently for change of working characteristics and strut lure. Research on the phase change has been carried out steadily and operation strategies of encapsulated ice storage tank are reported experimentally in several papers. (4) A review of recent studies on refrigeration/air conditioning system have focused on the system performance and efficiency for new alternative refrigerants. Evaporation and condensation heat transfer characteristics are investigated for tube shapes and new alternative refrigerants. Studies on components of refrigeration/air conditioning system are carried to examine efficiency for various compressors and performance of new expansion devices. In addition to thermophysical properties of refrigerant mixtures, studies on new refrigerants are also carried out, however research works on two-phase flow seemed to be insufficient. (5) A review of the recent studies on absorption cooling system indicates that heat and mass transfer phenomena have been investigated to improve absorber performance. Various experimental data have been presented and several simulation models have been proposed. A review of the recent studies on duct and ventilation shows that ventilation indices have been proposed to quantify the ventilation performance in buildings and tunnels. Main efforts have been focused on the applications of ventilation effectiveness in practice, either numerically using computational fluid dynamics or experimentally using tracer gas techniques. (6) Based on a review of recent studies on indoor thermal environment and building service systems, research issues have mainly focused on many innovative ideas such as underfloor air-conditioning system, personal environmental modules, radiant floor cooling and etc. Also, the new approaches for minimizing energy consumption as well as improving indoor environmental conditions through predictive control of HVAC systems, various activities of building energy management and cost-benefit analysis for economic evaluation were highlighted.
