The Environmental Kuznets Curve Hypothesis postulates an inverted-U shaped relationship between GDP per capita and various pollutants. Pollutants emission increases up to a certain level as income goes up; after that, it decreases. This paper investigates the relationship between industry pollutants taking industrial sulfur dioxide omission as example, and economic growth by using province-panel data set from 1989 to 2004 in 28 provinces of P. R. China. The result shows that the EKC hypothesis may be supported in the case of industrial sulfur dioxide, and the GDP per capital of turning point is about RMB 13,548 (at 1978 price). Except Shanghai, all the provinces GDP per capital in this study are less than RMB 13,548, indicating the amount of industrial sulfur dioxide emission will be increasing in the near future. To realize sustainable development and pollutants abatement, the central and local government should adopt an integrated strategy to protect environment.

In this study, we propose the guideline with strategic model for new product development. To establish the guideline, 1) we classify several types of successful surveyed cases that achieved open innovation through applying crowdsourcing into new product development environment, 2) draw case maps using two or three axis with characteristics such as: step of product development process, crowdsourcing frequency, and product type of each case, 3) define the type of applying crowdsourcing into new product development environment based on case analysis results, and tabulate a crowdsourcing type based on the defined crowdsourcing type, 4) finally, suggest the guideline with multiple points of view which embrace type of crowd, community management, participation method, knowledge adoption method, and reward policy. Using the suggested guideline will help a company to design and establish open innovation in new business model related to product development area.

국내 주요 국가산업단지인 여수국가산업단지, 울산국가산업단지 및 시화 반월산업단지 주변 토양에 대해서 2006년부터 2008년까지 3년 동안 상반기와 하반기로 각각 나누어 시료를 채취한 다음 중금속 농도와 분포특성을 파악하고, 부화지수를 이용한 토양 중금속 오염도를 평가하였다. 여수국가산업단지의 토양 중 Cd, Hg, Pb, Zn 및 Ni 농도가 다른 두 국가산업단지에서의 농도보다 더 높게 나타났으며, 시화 반월산업단지의 토양에서는 Cu, As 및 Cr의 농도가 높게 나타났으나 토양오염우려기준은 초과하지 않았다. 대체적으로 여수국가산업단지의 토양 중 중금속 오염이 다른 두 국가산업단지지역에 비하여 더 높게 나타난 것은 종합석유화학공업기지인 여수국가산업단지에는 입주해있는 석유화학공장들에서 발생하는 오염물질과 또한 이들을 수송하는 자동차 등의 비점오염원의 영향을 더 많이 받았기 때문인 것으로 판단되었다. 연구대상 지역별로 각각 구분하여 토양 중금속 결과를 이용한 주성분 분석결과 세 지역 모두 고유치가 1 이상인 주성분 2개를 각각 추출할 수 있었다. 여수 및 시화 반월국가산업단지에서는 Cd, Cu, Pb, Cr, Zn 및 Ni이 요인 1로, 그리고 As 및 Hg이 요인 2로 설명되었으며, 이는 두 지역 모두 석유화학과 기계, 철강, 전기전자 등의 배출원 영향을 받는 것으로 판단되었다. 울산국가산업단지은 Cd, Pb, Cr 및 Ni이 요인 1로, 그리고 Cu, As, Hg 및 Zn이 요인 2로 설명되었으며, 이는 기계, 석유화학, 운송장비, 비제조 등의 배출원 영향을 받는 것으로 판단되었다. 부화지수(EF)에 의한 오염도 평가 결과 3개 지역 모두 Cd, Pb 및 Zn의 EF값이 1 이상으로 나타나 이들 항목들의 오염개연성이 타 항목들에 비하여 높은 것으로 판단되었다. Cr은 시화 반월국가산업단지에서 1을 초과한 것으로 나타났으며, 3개 지역 모두 Zn의 부화지수가 상당히 높게 나타났다. 이상의 결과를 미루어 볼 때, 국가산업단지 토양의 중금속 오염은 토양환경 및 주변 농업환경에 악영향을 미칠 수 있으므로 다양한 중금속 배출원을 파악하여 각 배출원별로 철저한 관리가 필요할 것으로 판단된다.

Formaldehyde is important because of their irritant and toxic properties, mutagenicity and carcinogenicity. In this study, liquid chromatography-mass spectrometry (LC-MS) is used for the analysis of formaldehyde after derivatization with 2,4-dinitrophenylhydrazine (DNPH) cartridge. Analytical parameters such as linearity, repeatability and minimum detection limit were evaluated. The linearity ($r^2$) was 0.9997 when analyte concentration ranges from 25 to $200{\mu}g/l$. The relative standard deviation (%RSD) was 1.25 % for concentration of $200{\mu}g/l$. The minimum detection limit (MDL) was 0.73 ppbv. It was shown that LC-MS method has a great potential for formaldehyde analysis. The results of formaldehyde from the survey of Ban-Woll and Shi-Hwa Industrial Complex samples, the highest level was 6.20, 3.93 ppb, respectively. The highest emission level of formaldehyde at chemical plants in the Ban-Woll' Shi-Hwa Industrial Complex was 5421.25 ppb.

Objectives: Improvement of the reliability of work environment measurement results is one of the principal subjects to be resolved in the field of industrial hygiene. Thus, this study was conducted in order to review domestic programs for enhancing the reliability of work environment measurement results and propose a more efficient management plan for workplace monitoring. Materials and Methods: The current domestic programs reviewed in this study are the quality control system and evaluation system for industrial hygiene laboratories, the reliability system accompanied by KOSHA (the Korea Occupational Safety and Health Agency), the system of permissible exposure limits and observed inspection system for permissible exposure limits. Their contents and data were analyzed by reviewing articles, reports, and guidelines related to reliability improvement for work environment measurement results. Results: As a result of the literature review, all the domestic programs investigated in this study had both merits and demerits in terms of considering the reliability of work environment measurement results. In particular, the fact that preliminary notification is provided to the head of a workplace before implementation would be an obstacle for elevating the reliability of work environment measurement results. Conclusions: Based on the review results obtained from this study, it is proposed that on-site measurement without preliminary notification should be considered for a more efficient inspection system that would enhance the reliability of workplace monitoring.

This study was carried out to monitor suspected endocrine disrupting pesticides and industrial organic chemicals among circulated agricultural products in the north area of Seoul in 2001. Procymidone, vinclozolin, endosulfan, chlorothalonil, chloropyrifos and pendimetaline (pesticides) and butylated hydroxytoluene(industrial organic chemicals) were certified by GC-MS. Detected 6 pesticides were remained mostly in the green vegetables, spices and wild plants with $3\%$ detected. Butylated hydroxytoluene(industrial organic chemicals) used for green house cover stuffs was contained mostly in the green vegetables, spices and wild plants not in the fruits and cereals with $43\%$ detected. In the same agricultural products containing butylated hydroxy toluene showed same detection tendency with remaining endocrine disrupting pesticides.

Regarding the green environment, it is important to boost the spread of environmentally friendly vending machines and to operate the vehicles for their inventory replenishments while minimizing emissions of greenhouse gases. In general, the vending machine management company lacks capability to operate the supply chain effectively in an integrated way under the dynamic, complex, and stochastic environment. This paper presents a decision support system, termed DSSVM, for the operations of the general and smart vending machine supply chains with stock-out-based, one stage item substitution in a green logistics environment. The DSSVM supports the estimation of item demand and substitution probabilities, determination of operation parameters, supply chain analysis, what-if analysis, and $CO_2$ analysis for which various analytical models are employed.

The product information is defined as the information that is obtained in the whole life cycle of a product from design and manufacturing to marketing and it carries out the important role under the changeful environment. It is necessary to use computers for efficient product data sharing. But, in practice, because of various product data types and heterogeneous computing environment, it is difficult to share the product information among different computer systems. This paper presents the methodology for sharing the product information without a hitch in he-terogeneous computing environment by using the international standard of the product information ISO-10303 STEP and CORBA.

Geochemical study was carried out to find out soil contamination at the heaped soil, moved from bottom of the storage pond in Pohang industrial complex, in Moondug, Chemical analysis showed that contents of heavy metals in the soil were higher than those of the ordinary soil. Contents of Cu and Cd in the soil exceeded Korean standard of soil contamination. Especially content of Cu exceeded Korean standard of soil contamination(50ppm) at the six points and at one point content of Cu was 113.3ppm. Contents of Be were so higher than U.S RCRA standard(0.2ppm) that they can affect soil environment. The followed research about relation between pollutant and soil and proper measures are required to prevent soil contamination from affecting environment of Moondug.
