Background: Nasal polyps are benign mass of nasal mucose, chronic sinusitis are swelling of nasal mucose, so nasal polyps and chronic sinusitis take a place at the same time. Nasal polyps are located lateral wall of nose, middle meatus, between middle nasal concha and inferior nasal concha. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis and nasal polyps before and after treatment using computed tomography (CT). To compared before and after treatment of otitis media using earscope. Materials and methods: Five patients (4 mail and 1 femail) treated in our hospital between August 1998 and July 1999 were studied. Ages ranged from 9 to 23 years (mean age:13 years). All patients had a underlying family history, and past history(allergy or sinusitis of parents or brothers). Illness period was from 1 to 36 months (mean period:10.5 month). To ascertain the efficacy of treatment, CT were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. We classified treatment period into the type of allergic disease. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms. Results: Treatment period was from 126 to 157 days (mean period:140.7 days). To 3 patients with chronic sinusitis and nasal polyp, treatment period was 140.7 days, to 2 patients with otitis media and chronic sinusitis and nasal polyp, treatment period was 141.5 days. So they had no significance. Not nasal polyp from middle meatus, but also polypoid mucosal change of maxillary sinus is polyps Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis and otitis media using earscope and CT. Herbal medicine therapy was effective in increasing immunity, inhibiting allergic reaction and inflammation of respiratory system. we practice ECP(eosinophil cataionic protein) and MAST examination, objectify herbal medicine therapy.

Purpose : This study investigated the effect of bamboo stepping exercises on the blood pressure of the elderly. This study was performed for 8 weeks. Methods : The study participants included 25 people aged 65 and over. Of the participants, 16 were in the hypertensive elderly group and 9 were in the normal blood pressure elderly group. The participants stepped on semicircular bamboo for 20 minutes 3 times a week for 8 weeks. The participants' blood pressure was measured 3 times before and after 8 weeks of exercise. The mean values of the 3 before and after measurements were compared and analyzed statistically. Results : The systolic blood pressure of the hypertensive elderly group decreased significantly from $134.6{\pm}21.1mmHg$ to $119.9{\pm}18.1mmHg$ (p<.05). The diastolic blood pressure of the hypertensive elderly group decreased from $70.2{\pm}10.5mmHg$ to $66.1{\pm}9.8mmHg$, but the difference was not significant. The systolic blood pressure of the normal blood pressure elderly group decreased significantly from $127.2{\pm}18.7mmHg$ to $115.5{\pm}19mmHg$ (p<.05). The diastolic blood pressure of the normal blood pressure elderly group decreased from $72.6{\pm}11.3mmHg$ to $68.2{\pm}12mmHg$, but the decrease was not significant. Conclusion : After completing 8 weeks of the bamboo stepping exercises, the elderly participants' systolic blood pressure was effectively reduced. Today, lifestyle modifications, such as daily exercise, are necessary to control the blood pressure of the elderly. We hope that the bamboo stepping exercises, which are easy to perform and are not restricted by place and time, will become part of the elderly health policy.

Purpose: This study aimed to evaluate the effects of a mobile-based breastfeeding promotion program (M-BFGDM) that helps mothers with gestational diabetes. Methods: Forty-seven mothers participated in the study, of whom 22 were in the experimental group and 25 in the control group. To verify the effects, a lag design before and after the non-equivalence control group was used. The data collection for the experimental group was done before and after the intervention. Results: In the results, breastfeeding knowledge showed a significant difference in the interaction between measurement period and group (χ² = 8.14, p = .017), whereas breastfeeding intention did not show a significant difference in the interaction (χ² = 4.73, p = .094). There was no difference in self-efficacy interaction (F = 0.13, p = .856). The breastfeeding method showed no difference in interaction (F = 0.04, p = .952), whereas cross-analysis showed a significant difference in breastfeeding practice rate between the experimental group and the control group at 1 month postpartum (χ² = 7.59, p = .006). Conclusion: A mobile-based breastfeeding promotion program was developed and applied for gestational diabetic mothers, resulting in an increase in breastfeeding knowledge and an improvement in breastfeeding practice rate one month after childbirth. In addition, M-BFGDM managed to create a breastfeeding practice environment with fewer time and place restrictions. A program study that complements motivation is needed to improve breastfeeding in pregnant diabetic mothers in the future.

The Good Agriculture Practice (GAP) program, being established in China, is an optimal way for the sustainable utilization of the medicinal plant and animal resources. Most frequently used Chinese materia medica will be mainly produced from the GAP bases in the future. To assure the successful operation of GAP program, standard operating procedure (SOP) should be implemented for specific plants or animals. Both GAP and SOP include the requirements in many aspects from the ecological environment of cultivation place, germplasm and varieties, seedling and transplant, fertilization, irrigation, and field care, to harvest and process, package, transport and storage. As a complex system, GAP demands strong commitment from the pharmaceutical industry, local administrative involvement, long term R&D support, and years of time of development before a satisfactory result can be achieved.

Future space is currently getting a great deal of attention to apply ubiquitous computing technology. At the same time, various ubiquitous technology-based products are being developed with service scenarios in the views of diverse user groups predicted. Since these service models and scenarios need to be tested to verify effectiveness, it requires researchers to predict spatial shapes and service scenarios for future domestic environment that fulfills diverse future spatial requirements including ecological and user-oriented spaces, extended amenity getting maximum benefits from technology, etc. To support these developments, the need to make a physical test-bed, a real building model, is essential. However building a physical test-bed generally is economically expensive and even if the test-bed could be settled, it must be carefully designed before it is built In this paper, we suggest a virtual smart test-bed, called "V-PlaceLab", using virtual reality techniques. This system allows not only to inspect a scenario with the aid of computer simulation on a virtual environment, but also to design a virtual test-bed mentioned above.

Most previous robots had used the wheels as means for movement. These structures were relatively simple and easy to control and this is why the method had been used until currently. However, there are many realistic problems to move from one place to another in human life, for instance, steps and edges. So we need to develop the two-legged walking humanoid robot. The 2-legged walking Robot system has been vigorously developed in so many corporations and academic circles of several countries. However, 2-legged walking Robot has been mostly studied in view of the static walk. We design a stable humanoid Robot which can walk in high-speed through the research of the dynamic walk in this paper. Especially, worldwide companies have been interested in developing humanoid robots for a long time to solve the before mentioned problems so that they can become more familiar with the human form. The most important thing, for the novel two-legged walk, is to create a stable and fast walking in two-legged robots. For realization of this movement, an optimal mechanical design of 12 DOFS, a distributed control and a parallel processing control are implemented in this paper. This paper proves that high speed and stable walking can be achieved, through experiments.

For investigation of electrical properties of XLPE cable termination, we prepared a thermal contraction type kit and 6.6kV XLPE cable. The cable termination that have simulated defect by badness construction have been manufactured and their insulation characteristics such as ac and impulse withstand test have been measured. The influence of defects such as thickness decrease and heating time have been studied. When thickness decreased 1mm, the decreased of AC breakdown voltage value is not very distinctive. However, when thickness decreased 2mm, the insulation AC breakdown voltage value was very low down to 43kV. When approved heat for 300s than 60s, AC Breakdown voltage value appeared high. And also, after insulation breakdown took place, the sample was observed before and after disassembly, and the insulation breakdown hole was observed by means of optical microscope.

This paper summarized the changes in elementary school mathematics education that took place at the national level during the Enlightenment Elementary Mathematics Education period from 1876 to 1910. For this purpose, we divided the enlightenment period into three periods and examined major changes related to elementary school mathematics education at each period. The necessity of arithmetic education began to be recognized before the reform of the Taoist reform, and arithmetic education became a national curriculum in the beginning of the Taoist reform period. Particularly, during the reforming period of the Gap, the elementary mathematics textbooks of mixed Korean and Chinese were published. In the period when the intervention of the Japanese imperialism began, the arithmetic education has been reduced or weakened in accordance with the education policy of 'simple' and 'use'. It is also remarkable that an arithmetic book for elementary teachers was published at this time.

The purpose of this study was to present a developmental direction of the early childhood social education in kindergarten by investigating the mother's perceptions using the focus group interview. Mothers who have 4~5 year old children were selected for 3 focus group interviews. The following results were obtained: 1) The mothers recognized early childhood social education as an essential step before entering elementary school. 2) The mothers were found to have recognized that the cultivation of the various social situations of the children in kindergarten would be a very important task of the kindergarten, because kindergarten is a place for children to be introduced to social experiences for the first time in their lives. 3) Most of the mothers have the perception that early childhood social education showed positive effects on the development of their children. This perception was based on the evaluation of the social educational effect of kindergarten compared to that of elementary school.

Reinforced concrete floors constructed between movement restraints often crack seriously due to shrinkage after completion. One common mitigation measure is to construct the concrete floors in stages to allow part of the shrinkage movement to take place before completion. However, shrinkage movement analysis of concrete floors constructed in stages is quite cumbersome, as the structural configuration changes during construction, thus necessitating reanalysis of the partially completed structure at each stage. Herein, a finite element method for shrinkage movement analysis of concrete floors constructed in stages is developed. It analyses the whole structure, including the completed and uncompleted portions, at all stages. The same mesh is used all the time and therefore re-meshing and location matching are no longer necessary. This is achieved by giving negligibly small stiffness to the uncompleted portions, which in reality do not exist yet. In the analysis, the locked-in strains due to increase in elastic modulus as the concrete hardens and the creep of the hardened concrete are taken into account. Most important of all, this method would enable fully automatic shrinkage movement analysis for the purpose of construction control.
