Since most clothing research has still centered around buying behavior, the importance of consumer behavior which exists outside the purchase context has been neglected. This orientation focusing solely on purchase-related processes is deficient as it cannot account for consumer behavior that is recreational or that occurs without a recognized consumption need. In this vein, clothing browsing behavior can be a significant variable that has effects on clothing purchase-related variables. So to speak, browsers do make purchases at times; delayed-action purchases, impulse purchases and browsers may provide other less informed people with product information. In this study, we used definition proposed by Bloch and Richins(1983), which defines non purchase shopping(browsing) as 1,he examination of merchandises of a store for recreational or informational purposes without a current intention to buy. The specific objectives of the study were to identify the dimensions of clothing non -purchase shopping and to determine the causal relationship among clothing involvement, non-purchase shopping, impulse buying, purchase quantity, opinion leadership. The questionnaire method was used and 366 questionnaires were analyzed. Results can be summarized as follows. First, the non-purchase shopping was divided into two dimensions such as recreational non-purchase shopping and informational non-purchase shopping Of the two dimensions, recreational dimension explained the greater part than informational one. Second, it was revealed that clothing involvement was strongly positively related to non-purchase shopping, which influenced considerably on impulse buying, purchase quantity, and opinion leadership. In other words, clothing non-purchase shopping behaivor is very significant concept of clothing product category and has considerable effects on clothing buying though it occurs independently of purchase, so it seems that much more concern will be needed on this concept.

Objectives: The purpose of this study was to review clinical characteristics and working environments of sudden cardiac death (SCD) cases associated with a tire manufacturer in Korea, and review possible occupational risk factors for cardiovascular disease including nanoparticles (ultrafine particles, UFPs). Methods: We reviewed (i) the clinical course of SCD cases and (ii) occupational and non-occupational risk factors including chemicals, the physical work environment, and job characteristics. Results: Possible occupational factors were chemicals, UFPs of rubber fume, a hot environment, shift work, overworking, and noise exposure. The mean diameter of rubber fume (63-73 nm) was (larger than diesel exhaust [12 nm] and outdoor dust [50 nm]). The concentration of carbon disulfide, carbon monoxide and styrene were lower than the limit of detection. Five SCD cases were exposed to shift work and overworking. Most of the cases had several non-occupational factors such as hypertension, overweight and smoking. Conclusion: The diameter of rubber fume was larger than outdoor and the diesel exhaust, the most well known particulate having a causal relationship with cardiovascular disease. The possibility of a causal relation between UFPs of rubber fume and SCD was not supported in this study. However, it is necessary to continue studying the relationship between large sized UFPs and SCD.

Since the first report of the oak wilt disease at 2004 in Korea, the disease distributed over Korean peninsula and are still giving severe damages. The management of oak wilt disease in Korea has mainly focused on the control of insect vector, Platypus koryoensis. Neverthless the effective method for evaluating the pathogenicity of the pathogen, Raffaelea quercus-mongolicae (Rqm), and for screening chemical or biological agents with strong inhibitory activity against the pathogen, is absolutely necessary, an reliable method is not available so far. This study was conducted to develop the effective method for evaluating the pathogenicity of Rqm in oak trees. The culture suspensions of Rqm were artificially injected to the saplings of Quercus acutissima by using ChemJet tree injector. Three months after treatments, the treated saplings were cut and dipped into 1% fuchsin acid solution. There were significant differences in non-conductive area (%), discoloration area (%) and vertical discoloration length between the pathogen-injected and distilled water-injected control treatments. These results indicated that the pathogen is the causal agent for the dysfunction of water conductive tissue, which will finally result in wilt symptom. Re-isolation of the pathogen and PCR detection using specific primers for the pathogen also confirmed the presence of Rqm in the sapwood chips of the pathogen-injected saplings. These observations would be greatly applied to other related researches for evaluating the pathogenicity of tree wilt pathogens and biocontrol efficacy of the selected antagonistic microorganisms, in case that the wilt symptom is not easily shown by artificial inoculation of the causal agent.

In this paper, "Gyeonggi-Do household weekend travel survey" is used in order to analyze activity participation and travel behavior for the people who go to work on Saturday(workers) and those who do not go to work(non-workers). To find out causal relationship between activity participation and travel behavior, Structural Equation Models are developed. Examination of the causal relationship between activity participation and travel behavior identifies three stages. Firstly, subsistence activities and leisure activities are generated. Secondly, each activity participation produces trip volumes and travel times. Finally, the sum of travel times forms trip volumes. Looking into the activity participation stages for the workers, their subsistence activies have a tendency to take place first, and leisure activities usually follow. Non-workers generate more simple trip chains and most of their first stage activities are leisure related.

Changes in the price of materials in construction projects is one of the important variables. Therefore, measures are necessary to respond to the demand and supply of materials and price instability. In previous studies, mainly of ready-mix concrete and steel beam analysis was carried out. However, a study of non-ferrous material prices are still insufficient. So, in this study, the researcher identified the causal relationship between the construction cost and non-ferrous materials prices. Construction Cost Index was selected as a proxy variable of construction cost.

The purpose of this research is to analyse the cause and effect relations among management strategies, performance assessment and management performance in the hotel industry. The research result is as follows. A management strategy of the hotel industry has influence directly on a performance assessment through the non-financial factor, the financial factor and the study evaluation factor. And a financial performance assessment and a non-financial performance assessment have influence directly on the management performance. Total effects on a management performance of the hotel industry were 0.769 in a management strategies and 1.755 in a performance assessment. In comparison in the direct effects, the management strategies do not influence the management performance directly, and management performance is revealed through a performance assessment.

While product liability has been settled as a technical term in civil law, criminal law does not commonly accept technical term for it. Not like civil law, product liability in criminal law point outs individual responsibility and disability of normative order. Meaning that causation between individual's action of violation of duty and the result of danger of legal interest or infringement of legal interest must be proved. In criminal law excluding "non-result-constituted crimes (Unternehmensdelikt)", charge of injuring, accidental infliction of injury, homicide or involuntary manslaughter is problematic in product liability. Of course, it is necessary to distinguish whether the action related to the outcome is act or ommission. Also the causal relationship between the action and the result must be proved, and the intention or negligence should be recognized. In this paper, it analyzes cases that were problematic in Korea, Germany, Spain, etc. Mainly focusing on the problems revealed in the determination of causal relationship, especially recognizing criminal liability related to products. Furthermore it is followed by the view of reviewing the cause-and-effect relationship by 2 steps, dividing natural scientific causation and the normative causal relationship. In this process, to acknowledge criminal product liability in accordance with recognizing cause-and-effect relationship, there should be general risk of specific substance causing the outcome. This only premise can be meaningful to examine the casual relationship from specific cases. As it shows in some cases and theories, it is not contradicting general law of cause and effect by determining specific causal relationship by free evaluation of evidence if a general causal relationship does not exist. Also since judge's testimony does not hold a dominant position from rule of thumb, it is possible to recognize specific causal relationship. However this paper takes position that if there is no objective and reasonably undeniable cause and effect law. If there is no objective and reasonably undeniable causal law, which is the premise for recognizing concrete causal relations, judge should sentence guilty according to "in dubio pro reo" principle. In addition, it is not allowed for the defendant to burden unproven fact by free evaluation of evidence which has an effect of shift of burden of proof.

We have reviewed all cases and epidemiological studies that have reported the association between worker's exposure to metalworking fluids(MWF) and non-malignant respiratory diseases. The followings are main conclusions we critically reviewed. Exposure to MWF was believed to be significantly related to the risk of cough and phlegm. Relative risk caused by straight MWF was found to be higher in exposure to straight MWF than water-soluble MWF. We also found that exposure to water-soluble MWF significantly caused hypersensitivity pneumonitis (HP) and occupational asthma. The main culprits that cause the development of HP and asthma are believed to be microbes contaminated in MWF, ethanolamine and biocides. HP and asthma could be developed at even exposure to lower than $0.5mg/m^3$, exposure level recommended by NIOSH. Most epidemiological studies have reported that relationship between chronic bronchitis and exposure to MWF was significant. Although there were several studies that suggested the significant association between exposure to MWF and the development of rhinitis and sinusitis, we could not conclude the causal relationship because of lack of evidences.

Smart Work is an extended version of telecommuting or distance work pursuing an objective of work-life balance which is one of the hottest issues in management research. With diffusion of Smart Work, a problem has been raised that Smart Work makes the boundary between work and non-work blur, and may break the balance of work-life. However, work-life balance will be achieved by actively managing the boundary between work and non-work rather than passively taking the consequences. In order to find out whether Smart work improves work-life balance, we need to understand the precedence factors influencing on job satisfaction and the role of boundary management strategy which Smart Workers actively choose. This paper considered the bi-directional permeability between work and non-work domain and developed a research model containing a causal relationship among three factors, job autonomy, job involvement, and job satisfaction, and the moderation effect of boundary management strategy. The results show that both job autonomy and job involvement affect job satisfaction and boundary management strategy which Smart Workers utilize plays a moderating role influencing on job satisfaction.

In Korea, mass mortality of Quercus mongolica trees has become obvious since 2004. Raffaelea quercus-mongolicae is believed to be a causal fungus contributing the mortality. To evaluate the pathogenicity of the fungus to the trees, the fungus was multiple- and single-inoculated to the seedlings and twigs of the mature trees, respectively. In both the inoculations, the fungus was reisolated from more than 50% of inoculated twigs and seedlings. In the single inoculations, proportions of the transverse area of non-conductive sapwood at inoculation points and vertical lengths of discoloration expanded from the points were significantly different between the inoculation treatment and the control. In the multiple inoculations, no mortality was confirmed among the seedlings examined. These results showed that R. quercus-mongolicae can colonize sapwood, contribute to sapwood discoloration and disrupt sap flows around inoculation sites of Q. mongolica, although the pathogenicity of the fungus was not proven.
