The purpose of this study was to investigate the current status of first aids program in the safety education that was a part of the physical education curriculum in middle school. And this study is to supply the fundamental data for efficient safety education. The data was gathered with questionnaires given to 145 physical education teachers in Kangwon Province. Teachers think that the first aids education is essential in middle school curriculum. Taking considerations of the numerous accidents in society. This need will provide a remedy for any emergent situation and enlighten the safety-first-mind to protect against accidents. However, it is difficult to determine that efficient and good quality of first aids education is implemented in middle school. Based on the data, followings are some findings from the result; a) teachers lack experiences with first aids education, b) teachers are not equipped with sufficient theoretical and practical knowledge about first aids, and c) classroom teaching materials for first aids education are not furnished in the school at all. To suggest based on the above conclusions, the information about first aids must be employed in depth during the training period for present teachers along with learning physical education teachers so as to develop the theoretical knowledge and applicable capability about the education. Schools must stock adequate teaching materials for first aids education, and seek for effective and high quality education.
Reduction of Skin Irritation by Control of Skin Permeation of Methyl Paraben

The skin permearion study has two meanings in cosmetics. One is how to promore the skin permearion of active materials (e.g. skin whitening agents, anti-ageing agents) for improving their bioavailabilities and the other is how to decrease it of irritants (e.g. preservatives, perfumes, sunscreen agents) for reducing their skin side effects. In this study, we selected methyl paraben (MP), one of the preservatives, as a model irritant and tried to reduce the skin irritation by the decrease of skin permearion. Furthermore, the relationship between skin permeation and skin primary irritation was discussed. For in vitro skin permeation experiments, Franz type diffusion cells (effective diffusional area: 1.766 cm2) and the excised skin of female hairless mouse from 8 weeks old were used. The donor compartment was charged with oil only or O/W emulsion containing 0.3% MP. We selected 19 oils, including esters, triglycerides, plant oils, hydrocarbons, and alcohols, which are broadly used in cosmetics. We determined the oil/water partition coefficient of MP ar 32+C. The skin primary irritation was evaluated with female guinea pig (8-10 weeks, 350-400 g). The skin permeability of MP from the oils showed following order: ester oils > triglycerides > plant oils > hydrocarbons > alcohols We considered that this result was based on the different effect of each oil on the barrier function of stratum comeum. In O/W emulsion containing each oil, the skin permeability of MP decreased as the oil/water partition coefficient of MP increased. The skin primary irritation increased as the skin permeabiliry of MP increased. In conclusion, we suggest that the skin irritation could be reduced by the decrease of skin permeability of MP,which may be obtained by the good selection of oils in cosmetic preparations.
Development of Novel Polymeric Sunscreen Agent
( Hyo-joong Kim ),( Hye-sang Park ),( She-hoon Kang ),( Jong-tae Lee ) 대한화장품학회 1996 대한화장품학회지 Vol.22 No.2
A novel polymeric sunscreen agent was developed. It was prepared by the coupling reaction of 2-ethylhexyl 4-hydroxycinnamate with poly vinylbenzyl chloride(PVBC, average MW 6,500). In this reaction the reactivity was mostly affected by catalyst. In the absence of catalyst the yield was approximately 55% and in the presence of tetrabutylammonium bromide the yield was about 65%, but in the presence of tetrabutylammonium iodide the yield was 100% to give a average molecular weight 20,000 polymeric sunscreen agent. There were no side reactions, and its structure and purity were confirmed by various analytical methods, such as NMR, IR, and so on. UV radiation absorption efficiency is more than 70% compared with that of octyl methoxycinnamate. The solubility in polar oil, for example C<sub>12~15</sub> alkylbenzoate and caprylic/capric triglyceride, is more than 50%. It showed high stability in the time course of test including acceleration test. This polymer is safe to skin because of poor permeability to skin, no side products in the process of preparing, and easy elimination of excess starting materials.

The purpose of this research is to examine the relationship between search variety as search pattern and conversion behavior in experiential website. Search variety is measured by the number of menu clicked and conversion behavior is divided by conversion and conversion quantity during website visit. Regression model with multinomial logit selection was selected as methodology and estimated using web log file data. The results shows that search variety is significantly related to conversion behavior, but differential effect does exist toward two types of conversion behavior. In other words, search variety is positively related to conversion but negatively related to conversion quantity. This research has implication for online consumer behavior and real time customer management.

Infectious mononucleosis caused by primary Epstein-Barr virus infection is self-limited illness that is clinically characterized by fever, pharyngitis, and lymphadenopathy. Neurologic complications such as meningoencephalitis and Guillain. Barre syndrome can occur in 1 to 5% of patients with Infectious mononucleosis. Recently, we experienced mild form of Guillainfi Barre syndrome in a 25-year-old of patient who was diagnosed with infectious mononucleosis. Although both peripheral motor and sensory nerves were affected, the patient was fully recovered without assisted ventilation and paralysis of extremities. This case suggests that possibility of Guillain.Barre syndrome should be considered in patients with Infectious mononucleosis who present with minor neurological manifestations.
