The avoidance of the allergen of the house dust mite is one of the challenges to reduce and treat the symptoms of allergic diseases. Accordingly, various acaricidal agents are being used to kill the mite, but just killing it leaves the remains of it, which still act as the allergen. Therefore expelling the mite is thought as best policy to avoid the mite allergen. For this, some materials have been applied to repellent agents against the mite. Among them, a material with natural origin, known as the phytoncide, is being used for its repellent activity, as well as for its benefits for health. In this experiment, essential oils extracted from Korean white pine (Pinus koreaiensis S. et Z.) and hinoki cypress (Chamaecyparis obtusa), which are widely used as the source of phytoncide products, are studied for demonstration of the repellent effect against the house dust mites, Dermatophagoides farinae and D. pteronyssinus. Direct contact method was used to evaluate the repellent effect (%). And the results suggest the oils have a significant effect enough to be used as a source of repellent agent. For the repellent effect, the most effective concentration was $0.5{\mu}l/cm^2$ at 45 minutes both in the white pine and the hinoki oil.

Purpose: The purpose of this study is to examine the relationship between attitude toward death among Korean hostess (room salon/bar) in Busan and their suicide-related factors. Methods: The questionnaires were administrated to 120 Korean hostess. The questionnaires consist of 7 major concepts: death as liberation, death as natural phenomenon, fear of death, avoidance of thought about death, fear for the impact of death on family, frequency of thought of death, their capacities to resist suicidal impulses. Results: Interestingly, satisfaction for hostess working in room salons with their monthly incomes was negatively correlated with frequency of thought of death and was positively related to their capacities to resist suicidal impulse. Moreover, in terms of the factors influencing 'their capacities to resist suicidal impulse', for hostess working in room salons, 'fear for the impact of death on family,' and 'satisfaction with their monthly income' were found to significantly influence 'their capacities to resist suicidal impulses'. However, for hostess working at bars, 'death as liberation' was found to be the only one factor showing significant effect on 'their capacities to resist suicidal impulses'. Conclusion: For hostess working in room salons, their perceived monetary reward seems to affect their attitudes toward death and suicide-related thoughts. Understanding a person's attitudes toward death can be another way to help people in a difficult situation to prevent them from carrying out the worst.

English contract law has traditionally taken the view that it is not the duty of the parties to a contract to give information voluntarily to each other. In English law, one of the principal distinctions between insurance contract law and general contract law is the existence of the duty of disclosure in insurance law. This article is, therefore, designed to analyse the scope or extent of the duty of disclosure and the remedy for breach of the duty in English marine insurance law. The main purpose of this article is also to seek the alternative remedy for the breach. The results of analysis are as following : First, the scope of the duty of disclosure is closely related to the test of materiality and the concept of a hypothetical prudent insurer. The assured is required to disclose only material circumstances subject to MIA 1906, s. 18(1). The test of materiality, which had caused a great deal of debate in English courts over 30 years, was finally settled by the House of Lords in Pan Atlantic and the House of Lords rejected the 'decisive influence' test and the 'increased risk' test, and the decision of the House of Lords is thought to accept the 'mere influence' test in subsequent case by the Court of Appeal. Secondly, an actual insurer is, in order to avoid contract, required to provide proof that he is induced to enter into the contract by reason of the non-disclosure of the assured. But this subjective test of actual inducement is somewhat meaningless in sense that English court takes the test of materiality as a starting point and assumes the presumption of inducement even in case of no clear proof on the inducement. Finally, MIA 1906, s. 18 provides expressly for the remedy of avoidance of the contract for breach of the duty of disclosure. This means rescission or retrospective avoidance of the entire contract, and the remedy is based upon a fairly crude 'all-or-nothing' approach. The remedy of rescission is too draconian from the point of view of the assured, because he can be deprived of all cover despite he is innocent perfectly. An inadvertent breach from an innocent mistake is as fatal as wilful concealment. What is, therefore, needed in English marine insurance law with respect to remedy for the breach is to introduce a more sophisticated or proportionate remedy ascertaining degrees of fault.

English contract law has traditionally taken the view that it is not the duty of the parties to a contract to give information voluntarily to each other. In English law, one of the principal distinctions between insurance contract law and general contract law is the existence of the doctrine of utmost good faith in insurance law. The doctrine gives rise to a variety of duties, some of which apply before formation of the contract while others apply post-formation. This article is, therefore, designed to analyse the overall structure and problems of the doctrine of utmost good faith in English marine insurance law. The results of analysis are as following : First, the requirement of utmost good faith in marine insurance law arises from the fact that many of the relevant circumstances are within the exclusive knowledge of the assured and it is impossible for the insurer to obtain the facts to make a appropriate calculation of the risk that he is asked to assume without this information. Secondly, the duty of utmost good faith provided in MIA 1906, s. 17 has the nature as a bilateral or reciprocal, overriding and absolute duty. Thirdly, the Court of Appeal in Skandia held that breach of the pre-formation duty of utmost good faith did not sound in damages since the duty did not arise out of an implied contractual term and the breach did not constitute a tort. Instead, the Court of Appeal held that the duty was an extra-contractual duty imposed by law in the form of a contingent condition precedent to the enforceability of the contract. Fourthly, the scope of the duty of utmost good faith is closely related to the test of materiality and the assured is required to disclose only material circumstances subject to MIA 1906, s. 18(1) and 20(1). The test of materiality, which had caused a great deal of debate in English courts over 30 years, was finally settled by the House of Lords in Pan Atlantic and the House of Lords rejected the 'decisive influence' test and the 'increased risk' test, and the decision of the House of Lords is thought to accept the 'mere influence' test in subsequent case by the Court of Appeal. Fifthly, the insurer is, in order to avoid contract, required to provide proof that he is induced to enter into the contract by reason of the non-disclosure or misrepresentation of the assured. Sixthly, the duty of utmost good faith is, in principle, terminated before contract is concluded, but it is undoubtful that the provision under MIA 1906, s. 17 is wide enough to include the post-formation duty. The post-formation duty is, however, based upon the terms of marine insurance contract, and the duty lies entirely outside s. 17. Finally, MIA 1906, s. 17 provides expressly for the remedy of avoidance of the contract for breach of the duty. This means rescission or retrospective avoidance of the entire contract, and the remedy is based upon a fairly crude 'all-or-nothing' approach. What is needed in English marine insurance law is to introduce a more sophiscated or proportionate remedy.

The objective of this study consists in promoting seafood consumption by increasing its intake opportunities for children through analysis of seafood using frequency in the elementary school lunch program. For that purpose, randomly sampled out from elementary schools through the county were 155 dietitians and 5th grade 3581 children, on whom a mail survey was conducted to analyse their seafood using frequency, and preference, and lunch menu by seasons. Results of this study are as follows : The seafood using frequency of the respondents represented the highest value in one or two times a week, while obstacles in seafood use presented high values in the safety of food by 71.6% and children preference by 68.4%. The seafood intake frequency of the respondents showed the highest value in three or four times a week by 34.5% and the places of seafood intake indicated the highest response in the home by 43.5% and then school lunch and dining out. The dietitians responded that children for the most part had not a preference for seafood, whereas the children pointed out average by 46.2%. As for reasons for avoidance of seafood, the dietitians expressed the highest response in it depends cooking methods by 45.8%, while the children because of its peculiar taste and smell by 42.1%. Their required improvement showed the highest response in the taste improvement by 51.8%. The children most preference for seafood that dietitians thought included fried Alaska pollack and shrimp cutlet, while dislikes braised mackerels and seasoned cold jelly fish. Cooking methods frequently used were represented in order of soup, hot soup, and stew, and the children's preferred cooking method was from fried food. Above results suggested that the intention to increase seafood using frequency is needed to at the time of planning the menus so that more seafood-providing opportunities can be given. The development of cooking methods is urgently needed that can change the taste or the smell of seafood, and concurrently with this conveniences be taken into account in eating such as elimination of bones, etc. as early as the states of purchase or checking of seafood. The reflection of the preferred cooking methods is thought to contribute to the enhancement of satisfaction with the seafood as well as to the reduction of food remnants. The recommendation of intake of low preference but nutritionally good seafood is required to be expanded in nutrition education.

Background: Body image dissatisfaction among breast cancer survivors has been associated with psychological stress resultant from breast cancer and resultant surgery. This study aimed to examine the psychometric properties of the Malay Version of the Breast-Impact of Treatment Scale (MVBITS) and to investigate the associations of retained factors with the Hospital Anxiety and Depression Scale (HADS) and the Rosenberg Self-Esteem Scale (RSES). Materials and Methods: The MVBITS was 'forward-backward' translated from English to Malay and then administered to 70 female breast cancer patients who came to the Oncology Clinic of University Malaya Medical Centre, Kuala Lumpur, Malaysia to undergo chemotherapy. Principal component analysis (PCA) with varimax rotation was performed to explore the factor structure of the MVBITS. Associations of retained factors were estimated with reference to Spearman correlation coefficients. Results: The internal consistency reliability of MVBITS was good (Cronbach's alpha 0.945) and showed temporal stability over a 3-week period. Principal component analysis suggested two factors termed as 'Intrusion' and 'Avoidance' domains. These factors explained 70.3% of the variance. Factor 1 comprised the effects of breast cancer treatment on the emotion and thought, while Factor 2 informed attempts to limit exposure of the body to self or others. The Factor 1 of MVBITS was positively correlated with total, depression and anxiety sub-scores of HADS. Factor 2 was positively correlated with total and anxiety sub-scores of HADS. MVBITS was also positively correlated with the RSES scores. Conclusions: The results showed that the Malay Version of Breast-Impact of Treatment Scale possesses satisfactory psychometric properties suggesting that this instrument is appropriate for assessment of body change stress among female breast cancer patients in Malaysia.

Background: A critical features of Alzheimer's disease (AD) is cognitive dysfunction, which partly arises from decreased in acetylcholine levels. AD afftected brains are characterized by extensive oxidative stress, which is thought to be primarily induced by the amyloid beta ($A{\beta}$) peptide. In a previous study, Cinnamomum loureiroi tincture inhibited acetylcholinesterase (AchE) activity. That study identified AChE inhibitor in the C. loureiroi extract. Furthermore, the C. loureiroi extract enhanced memory in a trimethyltin (TMT)-induced model of cognitive dysfunction, as assessed via two behavioral tests. Rosa laevigata extract protected against oxidative stress-induced cytotoxicity. Administrating R. laevigata extracts to mice significantly reversed $A{\beta}$-induced learning and memory impairment, as shown in behavioral tests. Methods and Results: We conducted behavioral to examine the synergistic effects of C. loureiroi and R. laevigata extracts in inhibiting AChE and counteracting TMT-induced learning and memory losses. We also performed biochemical assays. The biochemical results showed a relationship between increased oxidative stress and cholinergic neurons damage in TMT-treated mice. Conclusions: A diet containing C. loureiroi and R. laevigata extracts ameliorated learning and memory impairments in the Y-maze and passive avoidance tests, and exerted synergistic inhibitory effect against AChE and lipid peroxidation.

Even thought modernized marine navigation devices help navigators, marine accidents has been often occurred and ship collision is one of the main types of the accidents. Various studies on the assessment method of collision risk have been reported, and studies using fuzzy theory are remarkable for the reason that reflect linguistic and ambiguous criteria for real situations. In these studies, collision risks were assessed on the assumption that the current state of navigation ship would be maintained. However, navigators ignore or turn off frequent alarms caused by the devices predicting collision risk, because they think that they can avoid the collisions in the most of situations. This paper proposes a model of predicting ship collision risk considering the general patterns of collision avoidance, and the approach is based on fuzzy inference and discrete event system specification (DEVS) formalism.

Objective: The purpose of this study was to investigate the correlation between activity of daily living and social psychology and work mind of office workers with non-specific chronic neck pain (NSCNP). Design: Crossed-sectional study Methods: 86 patients with NSCNP were recruited for this study. Neck disability index (NDI) and Numerical pain rating scale (NPRS) were used to check the pain intensity and disability of patients with neck pain. To find out the occupational factors of the subjects, the Korean version of Latack Coping Scale was used. And,To find out the socio-psychological factors of the subjects, the Korean version of depression anxiety stress scale (DASS-21) was used. We performed correlation for each variable. Results: The correlation between NPRS and NDI and DASS-21 Scale were clear positive correlation (p<0.05). There was no statistical significance between the LATACK control group and the pain and disability index (p>0.05). A clear positive correlation was established between the avoidance group of LATACK and pain (p<0.01). Conclusions: Through this study, it is necessary to have time to manage depression, anxiety, and stress in the treatment of neck pain in office workers who spend a lot of time sitting. In addition, it is thought that there should be the ability to control oneself about one's duties in the workplace.

The purpose of this experiment was designed to investigate the effects of medicinal herbs (MH) extracts on dementia induced by trimethyltin chloride (TMT) in rats. Six-week-old male Sprague-Dawley rats were randomly divided into five groups; normal group (group 1), control group (group 2), MH extracts group (250, 500 mg/kg) (group 3, group 4) and positive control group (tacrine group, group 5). In the control group to induce dementia, a 2.5 mg/kg of TMT intraperitoneal injection was used for 14 days (1 per day) in the rats. In the MH extracts group 250 mg/kg and 500 mg/kg of MH extracts were medicated in an oral inoculation for 20 days (1 per day). After 30 minutes, a 2.5 mg/kg of TMT intraperitoneal injection, which causes dementia, was used for 14 days (1 per day). In the positive control group (Tacrine group) 10 mg/kg of Tacrine, the dementia treatment, was medicated in an oral inoculation. After 30 mintues, 1 mg/kg of TMT intraperitoneal injection, which causes dementia, was used for 14 days (1 per day). The present author observed the passive avoidance performance test, and memory ability test (Y maze test), the values of MDA, acetlycholinesterase (AchE) activity in the brain and antioxidant enzyme in serum. MH extracts significantly improved memory of AD model rats in the Y-maze test, and also significantly improved memory of AD model rats in the passive avoidance test. MH extracts significantly reduced AChE activity, and significantly increased the SOD level, but not catalase and MDA. From the results above, MH extracts is thought to be effective in the improvement of antioxidant enzymes and memory ability.
