The current study evaluates the capacity of eugenol to regulate immediate allergic reaction by control of histamine release. Administrations of eugenol (1 M/kg. i.p.) at 60 min before and 5.10 min after the compound 48/80 treatment (8 mg/kg.i.p.) were shown the mortality rates as 0.44.4. and 77.8%. respectively. A 60 min before administered group revealed a singificant inhibition of serum his-tamine release compared with those of 5 and 10 min after the compound 48/80 injection. Eugenol (6-48mM) was also showed a dose-dependent activity on the compound 48/80-induced histamine release from the highly purified population of Alcian Blue-positive peritoneal mast cells. These results indicate that in vitro treatment with exogenous eugenol inhibited the active response of mast cell populations and modulated its characteristics.

In other to know the characteristics of the air sea heat flux at on the coastal of Jeju Island. when there was a snowfall in winter. It is used as the basic data are Automatic Synoptic Observation System(ASOS) compiled by Jeju Regional Meteorological Office(JRMO) from 1993 to 2002, and SST data derived from National Oceanographic Research Institute(NORI) and National Fisheries Research & Development Institute(NFRDI) observations. the heat flux of the coastal of Jeju Island shows its maximum in January(latent heat flux : 35Wm^(-2) , sensible heat flux : 85Wm^(-2)), and shows its minimum in July(latent heat flux : -l3Wm^(-2), sensible heat flux : -5Wm^(-2)) the more the temperature gap between the air and SST is large and the stronger a wind is, the more it supplies the heat from the sea to the air. it shows that the north-western areas is about three times higher than other areas in Jeju Island. when fresh snow cover is 0.0∼0.9 ㎝, the mean bowen's ratio(for 1993∼2002) is 0.63∼0.67. when it is 1.0∼4.9 ㎝, the mean bowen's ratio(for 1993∼2002) is over 0.72 or more. When bowen's ratio increased upto 0.63∼0.80. fresh snow cover is increased gradually, therefore, it is researched the there is proportion between the fresh snow cover and the bowen's ratio.

Improvement on accuracy in three-dimensional location decision on the sea has been studied quite much by adding the characteristics of the sea to the three-dimensional positioning method on land. However, there are only a few studies on the information on submarine topography - the improvement on accuracy in the information on depth of water - which is an important factor for ocean engineering works like dredging on the coast, reclamation, construction of harbors and ocean engineering facilities, etc. In this study, I purposed a depth sounding system which consists of and echo sounder, a GPS and an IMU. And I added a depth sounding data correction methods to the system. In this correction methods, first, included unit of attitude angle correction of survey vessel. And included units of critical range of turbidity and heave correction.

목 적 : 연취급 근로자를 대상으로 사회 심리적 스트레스 수준을 알아보고 이를 기초자료로 활용하며 사회 심리적 스트레스와 연노출 지표들간의 관련성을 알아보고자 시도하였다. 방 법 ' 1차 연제련업종의 근로자 234명을 대상으로 일반적 특성, 사회 심리적 스트레스, 직업적 특성과 사회적 지지를 문진과 설문지를 통해 확인했으며 연노출 수준을 알기 위해 혈중 ZPP 농도, 혈중연농도, 요중 δ-ALA 배설량, 혈색소, 혈구용적치등을 측정했다. 결 과 : 단일변량 분석결과 혈중 연농도 수준과 직업적 특성에 따른 사회 심리적 스트레스는 유의한 차이가 있었으며 혈중 연농도가 증가함에 따라 스트레스 수준도 증가되는 경향을 나타냈다. 사회 심리적 스트레스와 연노출 지표 및 다른 변수들간의 관련성을 파악하기 위하여 상관분석을 실시한 결과 혈중 연농도만이 사회 심리적 스트레스와 양의 상관관계를 나타냈으며 유의했다. 결 론 : 고농도 연노출의 가능성이 있는 직종인 경우 기존의 연관련 자각증상에 대한 설문조사와 함께 사회 심리적 스트레스 측정도 병행하여 실시하는 것이 연에 의한 건강장해를 조기에 발견하고 예방하는데 필요하다. Objectives : This study was carried out to assess psychosocial distress of lead workers and to examine the relationship between lead exposure indices and psychosocial distress. Methods The study design was cross-sectional and research subjects were 234 lead workers in primary smelting industry. General characteristics, job characteristics and social support were obtained by self-administered questionnaire and history taking. Psychosocial distress was measured using PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Blood lead(PbB), zinc protoporphyrin(ZPP), δ-aminolevulinic acid in urine (ALAU) were selected as indicators of lead exposure. Results : There was significant difference in PWI according to lead exposure level and job characteristics. The results of correlation analysis showed that PWI was significantly correlated with PbB (r=0.203, p=0.002). Conclusions : Our results supported the association between lead exposure and psy-chosocial distress. The inclusion of psychosoclal distress measurement as a special health examination for lead workers was highly recommended for the effective health manage-ment.

Accuracy improvement in determination of three-dimensional location on the sea has been studied quite much by adding the characteristics of the sea to the three-dimensional positioning methods on land. However, there are only a few studies on the accuracy improvement concerning water depth measurement and seafloor topography, which is required for almost all of the works in ocean, such as dredging, reclamation, habor construction and constructing ocean facilities. In this study, among the precision decline main causes of sounding, I suggested the characteristics of sounding data acquired by echo sounder with increasing of turbidity For this, I acquired sounding data by inputting turbidity inducer artificially in artificial water tank. And then achieved regression analysis. Conclusion are as following : Sounding Capabilities can be divided into three ranges according to the turbidity : normal range, critical range and the range where data can not be obtained by an echo sounder

Septoplasty with turbinate surgery is common surgical treatment In patients with septal deviation and chronic hypertrophic rhinitis. The aim of this study was to evaluation objective outcomes of septoplasty with turbinate surgery by analysis of subjective symptom score with objective acoustic rhinometric test before and after surgery, prospectively. Materials and Methods: We reviewed 45 adult patients which were done septoplasty with bilateral turbinectomy or turbinoplasty and followed up at least 3 months by one rhinologist from November 1999 to April 2000, prospectively. We analyzed subjective symptom score. minimal cross-sectional area (MCA) , C-notch cross-sectional area, and total volume of both nasal cavity before and after surgery. Correlation test was studied between symptom improvement and acoustic rhinometric results. Results: Twenty nine cases were male and sixteen cases female. The average age was 26.9 year-old (range: 17 to 57 years). There was significantly improvement of symptom score in postoperative 3 months (p<0.05). There was significantly increased C-notch cross-sectional area and total volume in postoperative 3 months. Symptoms improvement were associated with acoustic rhinometric profiles, but, there was not significantly correlation. Conclusion: Septoplasty with turbinate surgery is considered to be effective for nasal obstruction in patients with septal deviation and turbinate hypertrophy. Acoustic rhinometric test is favorable objective test for evaluation of symptom improvement after septal surgery.

Magnetic particles with alternating magnetic field are expected to be useful as thermoseeds in hyperthermic cancer treatment, since they can be targeted and confined to the cancer site. Hard magnetic ferrites such as barium ferrite and strontium ferrite are good candidates for thermoseeds of hyperthermia because of their great hysteresis loss. In order to verify the effect of Sr-substitution to Ba-site, synthesized Ba1-xSrxFe12O19 microspheres with various compositions through spray pyrolysis followed by sol synthesis using barium nitrate, strontium acetate and iron nitrate. Coercive force was increased with increasing substitution amount of Sr whereas magnetic saturation was almost constant. Spherical microspheres with average diameter of 11.7~17.0 ㎛ were produced by spray pyrolysis at 400~1000℃. The mean size was dependent on the pyrolysis temperature and flow rate of carrier gas. In order to obtain a single phase of SrFe12O19 crystal, the spray pyrolyzed spheres were undertaken subsequent heat-treatment above 1000℃. During the subsequent heat-treatment, however, spherical microspheres were agglomerated because of necking between particles. Further study has to be continued working on synthesis of pure SrFe12O19 crystal by means of improvement of pyrolysis temperature scheme and extend the heating period.
