The health industry of China is faster than before, so it will be rank 5th at world-wide markets in 2010. Firstly, the custom tariff was lower at 15% in 2000 and at 10.4% on June 2005. And, it will be lower into 9.8% in 2010. Secondly, this is because of expansion of purchase power on increase in economic growth, extended human life expectancy. As it is entered the WTO in January 2002, it will positively affect on export of Korea for China. This paper focuses on the analysis of export increase caused by reduction of custom tariff in China. As above mentioned, the time schedule on average reduction of custom tariff was 15% in 2000, 10.4% in 2005. Then, it will be lower into 9.8% in 2010. As the empirical test related health industry, it presents 19.80% export increase rate for China of Korea on reduction of custom tariff from 2001 to 2010. The exporting of drug for China will be up to 17.85% for 10 years. Also, the exporting of Biomedical will be up to 20.99%, and respectively 22.95%, 22.60% in Cosmetics and food industry. Conclusionally, the exporting of this health industry will be increase greatly, compared with any other industries. So, it is necessary that firms increase in R&D investment and government support as policy for health industry.

This paper describes a 2D discrete-time wavelet transform for which the Q-factor is easily specified. Hence, the transform can be tuned according to the oscillatory behavior of the image signal to which it is applied. The tunable Q-factor wavelet transform (TQWT) is a fully-discrete wavelet transform for which the Q-factor, Q, of the underlying wavelet and the asymptotic redundancy (over-sampling rate), r, of the transform are easily and independently specified. In particular, the specified parameters Q and r can be real-valued. Therefore, by tuning Q, the oscillatory behavior of the wavelet can be chosen to match the oscillatory behavior of the signal of interest, so as to enhance the sparsity of a sparse signal representation. The TQWT is well suited to fast algorithms for sparsity-based inverse problems because it is a Parseval frame, easily invertible, and can be efficiently implemented. The TQWT can also be used as an easily-invertible discrete approximation of the continuous wavelet transform. The transform is based on a real valued scaling factor (dilation-factor) and is implemented using a perfect reconstruction over-sampled filter bank with real-valued sampling factors. The transform is parameterized by its Q-factor and its oversampling rate (redundancy), with modest oversampling rates (e. g. 3-4 times overcomplete) being sufficient for the analysis/synthesis functions to be well localized. Therefore, This method services good performance in image processing fields.

Food hygiene practices must be maintained from farm to table in order to prevent contamination by microorganisms. This study was conducted to investigate consumer hygiene practices related to the refrigerator storage of meat, including a microbial analysis, monitoring of refrigerator temperatures and consumer surveys of female homeowners in the capital area of Korea. Home refrigerator temperatures were maintained above $5^{\circ}C$ in 26 (19.7%) of the 132 houses investigated. The percentage of the refrigerators with a total microbial count over $10^2\;CFU/100\;cm^2$ was 14.4%. No E. coli, Salmonella spp. or Listeria monocytogenes microbes were detected. However, Staphylococcus aureus was detected in 14 houses (10.6%). The only statistically significant difference in hygiene practices between the non-contamination group and contamination group was in the last time of refrigerator cleaning (p<0.01), as determined by the consumer survey. To improve food hygiene when using a refrigerator, raw materials must be packaged, meat should be stored only on a designated shelf, and cooked foods must be contained to prevent cross-contamination. The refrigerator should be cleaned regularly, at least once a month, and refrigerator thermometers should be monitored below $5^{\circ}C$ in order to keep food safe.

Korea's national park system resembles that of Japan in many ways. In this study, National park Systems of the two countries are compared from a standpoint of their historical backgrounds to be formed and in aspect of its conservation by the main revision of national park laws in perspective. In conclusion it was found out that Korea's toleration-based regulations on building park amenities have gradually neglected the park conservation effort, whereas Japan's authorization-oriented regulations have streng thened their emphasis on park conservation. From the comparison as above, the polices to be modified for Korean national park are proposed as follows: 1. National park system, which values diversity of species, is to be proposed. For this, the Article 8 which allows a development of National parks, Enforcement Ordinance Article 4, The Article 18 of Law, Enforcement Regulation Article 6 & 7 of National Park Law should be reviewed for deletion and revision. 2. On the basis of the laws, zoning system should be readjusted by discriminated conservation policy. Also, the readjustment of zoning system should be enforced after thorough analysis and research on the value of natural resources in the national park. 3. Korea should closely review the recently revised Japanese laws on the national parks and nature revitalization promotion for applying them to conservation policy of Korean national parks.

The amount of water resources that can be used tend to be decreased gradually. In contrast, the rapidly increasing water consumption is a problem that need to be addressed. Renovation and equipment replacement to improve energy efficiency and to reduce expenditure for building usage is required. But the excessive initial investment cost and the prolonged of pay back period may be uneconomical choice. Water usage for cleaning the toilet bowl accounts for 27%of the total water usage. Water-saving valve that can select the amount of water for cleaning toilet bowl can be reduced expenditure. After installing water-saving valve, analysed the economic effects. Water-saving valves compared with flush valves, and researched the amount of water usage. Then analyzed for the economic effects. Water-saving valve was used 5.6 ${\ell}$/time for cleaning toilet bowl. In contrast, flush valve was consumed 8.4 ${\ell}$/time. Water-saving valve's water-saving rate was 33.3%. The initial payback period for Water-saving valve was 459.5 days. By a small investment in water saving valve, the economic benefits can be obtained.

Thermal shock resistance property has recently been considered to be one of the most important basic properties, in the same way that the transverse-rupture property is important for sintered hard materials such as ceramics, cemented carbides, and cermets. Attempts were made to evaluate the thermal shock resistance property of 10 vol% TaC added Ti(C,N)-Ni cermets using the infrared radiation heating method. The method uses a thin circular disk that is heated by infrared rays in the central area with a constant heat flux. The technique makes it possible to evaluate the thermal shock strength (Tss) and thermal shock fracture toughness (Tsf) directly from the electric powder charge and the time of fracture, despite the fact that Tss and Tsf consist of the thermal properties of the material tested. Tsf can be measured for a specimen with an edge notch, while Tss cannot be measured for specimens without such a notch. It was thought, however, that Tsf might depend on the radius of curvature of the edge notch. Using the Tsf data, Tss was calculated using a consideration of the stress concentration. The thermal shock resistance property of 10 vol% TaC added Ti(C,N)-Ni cermet increased with increases in the content of nitrogen and Ni. As a result, it was considered that Tss could be applied to an evaluation of the thermal shock resistance of cermets.

Hydraulic dead-zone and particle removal efficiency in the base frame of a constructed wetland was evaluated with computational fluid dynamics (CFD). The fraction of hydraulic dead-zone was estimated to be 1.2-2.1 % (v/v) and it was attributed to the artificial islands developed in the constructed wetland. Solids deposition rate could be increased with higher hydraulic retention time (HRT, ranged from 2.2 to 4.2 hr) of the wetland and larger particle size (ranged from 10 to $50{\mu}m$) in the influent. Experimental results showed that the volume concentration of the particles smaller than $10{\mu}m$ in diameter was varied from $1.99{\times}10^3{\mu}m^3/ml$ (HRT 12.8 hr) to $3.92{\times}10^3{\mu}m^3/ml$(HRT 2.2 hr) in the influent of the constructed wetland. With the effluent volume concentration data, removal efficiency of those particles was calculated to be 71.2 and 24.7 % when the HRT was 12.8 and 2.2 hr, respectively. Similar trend with the HRT variation could be identified with CFD analysis.

The purpose of this paper was to review the problems relating to Korea's occupational health services and suggest ways to improve them. Korea can be classified as a welfare state type of conservative corporatism partially interwoven with liberalism. While experiencing compressed economic growth, the economic sectors of developed (excess areas) and developing (deficient areas) countries are interwoven. Therefore, it is necessary to perfect conservative corporatism along with a complementary reinforcement of liberal contents and to apply a multilayered approach focusing on complementing the deficient areas. It is essential to form a national representative indicator related to occupational health, and a strategy for selection and concentration is needed. The proposed central indicator is the occupational health coverage rate (OHCR), which is the number of workers who have applied for mandatory occupational health services under the Occupational Safety and Health Act in the numerator with the total working population in the denominator. This paper proposes ways to raise the OHCR, which is currently at the level of 25%-40%, to 70%-80%, which is the level of Japan, Germany, and France. To achieve this target, it is necessary to focus on small businesses and vulnerable workers. This is an area of market failure and requires the active input of community-oriented public resources. For access to larger workplaces, the marketability of services should be strengthened and personal intervention using digital health resources should be actively attempted. Taking a national perspective, work environment improvement committees with tripartite (labor, management, and government) participation for improvement of the working environment need to be established at the center and in the regions. Through this, prevention funds linked to industrial accident compensation and prevention could be used efficiently. A national chemical substance management system must be established to monitor the health of workers and the general public.

우주 기원의 방사성 핵종(核種)은 근래에 지형연구에 널리 활용되고 있다. 본 연구에서는 우주 기원의 방사성 핵종인 $^{10}$ Be과 $^{26}$ Al를 이용하여 만어산의 토르와 암괴류를 대상으로 그 구성 암석의 지표 노출 연대와 침식률을 측정하였다. 연구 결과, 토르는 적어도 약 6만 5천년 전, 그리고 암괴류는 적어도 3만 8천년 전에 노출된 것으로 나타났다. 한편, 토르와 암괴류의 구성 암석의 표면 침식률은 각각 9m/Ma 15m/Ma인 것으로 나타났다. 이러한 침식률의 차이는 풍화 및 침식에 대한 국지적인 조건이 다르기 때문인 것으로 생각된다. 특이한 점은, 산정부에 위치한 토르의 구성 암석들 중 일부가 $^{26}$ Al/$^{10}$ Be과 $^{10}$ Be를 이용하는 Lal (1991)이 밝힌 정상상태 침식구역(steady-state erosion island)에서 벗어나 있는데 이것은 이 토르의 표면이 비정상적인 침식의 경로를 겪었다는 것을 의미하며 본 연구에서는5cm-60cm 정도의 표면이 여러 번 떨어져 나갔다는 것으로 판단된다.

최근 국적취득조건부나용선에 승무하는 외국인 해기사에게 우리나라의 승무자격증을 발급받아야 하는지에 대한 의문에 제기되었다. 이는 선박직원법 제25조 제1항의 준용규정과 제10조의2의 승무자격증 발급규정과의 관계에 대한 해석상 이론이 제기될 수 있어 발생하는 문제이다. 이 연구는 동 준용규정을 검토하여 그 해석론적 해결방안을 제시하는 것을 목적으로 한다. 이 연구의 결론은 다음과 같다. 첫째, 국적취득조건부나용선에 대한 관할권은 해당 선박이 치적한 그 3국에 귀속하고, STCW협약상 외국인 해기사에게 발급되는 승무자격증은 기국에 의하여 발급되어야 한다. 둘째, 법 제25조의 준용규정은 동법의 개정입법취지에 맞게 BBC/HP에 대하여 외국선박의 기국이 가지는 관할권을 침해하여 우리 선박직원법의 요건을 적용하지 않도록 하여야 한다. 셋째, 이 준용규정은 국제규범에 따라 기국이 관할권을 가지는 각종 증명서의 발급에 관한 규정을 제외하고 승무기준과 같이 STCW협약에서 규정하지 않는 분야에 대해서만 준용하도록 하여야 한다. 넷째, 제10조의2 제1항은 BBC/HP에 승무하고자 하는 외국인 해기사에게 우리나라 승무자격증을 발급받도록 요구하는 규정은 아니다. 요약하면, 제10조의2의 규정은 한국선박에 승무하고자 하는 외국인 해기사에게 승무자격증을 발급받도록 하는 규정으로만 운용되어야 할 것이다.
