바다방석고둥을 원료로 한 신제품 개발에 관한 일련의 기초 연구로 저장성 부여를 위하여 시도하는 고온가열처리 조건 (F_0 5분, F_0 10분, F_0 15분 및 F_0 20분)에 따른 바다방석고둥의 성분변화에 대하여 살펴보았다. 바다방석고둥 통조림은 살균을 5분 이상 처리하는 경우 저장 중 팽창관이 발생하지 않았고, 또한 생균수가 검출되지 않아 저장성이 있었다. 고온가열처리 정도가 증가할수록 바다방석고둥의 일반성분 중 수분함량은 감소하였고, 조단백질 함량은 증가하였으며, 조지방 및 조회분 함량은 거의 변화가 없었다. 또한 바다방석 통조림은 고온가열처리 정도가 증가할수록 이취에 관여하는 휘발성염기질소 함량, pH와 색조에 관여하는 갈변도는 증가하였고, 영양에 관여하는 구성아미노산, 무기질과 맛에 관여하는 유리아미노산, TMAO, total creatinine 및 수율 둥은 감소하였다. 이들을 색조, 조직감 및 맛에 대하여 관능검사한 결과 자숙 처리한 시료에 비하여 모든 항목에서 F_0 10분까지는 차이가 없었으나, 그 이상 가열처리한 경우 품질이 저하하였다고 인지되었다. 이상의 결과로 미루어 보아 바다방석고둥을 고온가열처리하여 신제품을 개발하고자 하는 경우 F_0 값이 10분 이상이면 바람직하지 않은 것으로 판단되었다. The top shell, Omphalius pfeifferi capenteri meat vacuum-packed in can (diameter× height, 74.1 ㎜ × 50.7 ㎜) were heated at 115℃ up to F_0 values of 5 min, 10 min, 15 min and 20 min, and the changes in food components were studied. After 14 days storage at 37℃ and 55℃, no growth of microorganism and panelling were recognized from the canned meats which were sterlized at 115℃ with F_0 value of 5 min and over. In the case of proximate composition of the canned meats, the moisture content decreased with the increase of F_0 value, while crude protein increased. The increase of volatile basic nitrogen content, pH and degree of browning and the decrease of mineral, total amino acid, free amino add, trimethylamine oxide, total creatinine contents and yields were observed during thermal processing. In sensory evaluation on color, texture and taste in the canned meats, no significant difference was observed among a boiled sample and the canned meats heated at F_0 value of 10 min and below. But, in the canned meats heated at F_0 value of over 15 min, its sensory scores decreased with the increase of F_0 value. From these results, the reasonable F_0 value for preparation of the heat-treated top shell meats was in the range of 5∼10 min.

The purpose of this study was to evaluate the spatial relationship of facial bone more accurately. For this study, the three-dimensional images of dry skull were reconstructed using computer image analysis system and three-dimensional reconstructive program involved CT. The obtained results were as follows : 1. Three-dimensional reconstructive CT results in images that have better resolution and more contrast. 2. It showed good marginal images of anatomical structure on both three-dimensional CT and computer image analysis system, but the roof of orbit, the lacrimal bone and the squamous portion of temporal bone were hardly detectable. 3. The partial loss of image data were observed during the regeneration of saved image data on three-dimensional CT. 4. It saved the more time for reconstruction of three-dimensional images using computer image analysis system. But, the capacity of hardware was limited for inputting of image data and three-dimensional reconstructive process. 5. We could observe the spatial relationship between the region of interest and the surrounding structures by three-dimensional reconstructive images without invasive method.

This paper analysed the induced current density by electric field of human body under the 765 kV transmission line considering permittivity and conductivity. As permittivity of human body is very high as 10^6 at 60Hz, special numerical computation technique in Surface Charge Method(SCM) for composite media with extremely different propertis is applied to reduce calculation error of induced current density and electric field inside the human body. Calculation results show that the average of the induced current density human body is about 3mA/m^2, which is less than ICNIRP criterion(10mA/m^2)

Objects : Recent studies of psychosocial adjustment after hospitalization have found that the combination of maintenance antipsychotic drug treatment and psychosocial treatment including psychoeducational program are highly predictive of social rehabilitation and reduction of subsequent relapse. Two groups of patients with refractory chronic schizophrenia were preliminarily compared to determine the effect of a psychosocial treatment program on the quality of life in refractory chronic schizophrenics in an open comparative trial. Methods : One group(N=11) was assigned to approximately six months of the psychosocial treatment program(including psychoeducation program and activity program such as interpersonal relationship program, social skill training, self management program, outings, etc), in a group format, twice a week and a fixed maintenance dosage of clozapine ; while scale(QLS) was used to provide an objective measure of changes in patient's psychosocial functioning and a general assessment of psychopathology was made using the Brief Psychiatric Rating Scale(BPRS). Results : Both BPRS total positive score and the QLS total score, especially in the intrapsychic foundation factor of the scale showed a statistically significant improvement in the psychosocial treatment group. But there was no significant change in both BPRS and QLS scores over a 6-month period in the non-psychosocial treatment group. A significant negative correlation was found between the negative symptom and changes of QLS total, instrumental role and common object and activities scores respectively after receiving a 6-month of the psychosocial treatment program. Conclusion : These results suggest that a psychosocial treatment program including the integration of psychoeducation and a skill training oriented activity program serve as an outpatient treatment modality to improve the quality of the life in refractory chronic schizophrenia. To further clarify the effect of psychosocial treatment in chronic schizophrenia, a randomized trial should be done.

With biological effects by ELF(Extremely Low Frequency) magnetic field generated from power system, the transient magnetic field from electric appliances is a major issue presently. Because the transient magnetic field induces higher current than the power frequency field inside living bodies, transient magnetic field exposure has been much focused. In this paper, it is shown that transient magnetic field from electric home appliances can be characterized as magnetic dipole moment. In this method, the dipole moment vector is assumed by allowing an uncertainty of 6 dB in the estimated field. A parameter M that represents biological interaction was applied also. The proposed method was applied to 6 type of appliances(Mixer, Microwave oven, PC, etc.) and their equivalent magnetic dipole moment and harmonic components were estimated. As the results, the useful data for quantifying magnetic field distribution around electric appliances were obtained.

Purpose : To compare the proliferation potential of the epithelial cells between unicystic ameloblastoma (UA), dentigerous cyst (DC), and odontogenic keratocyst (OKC) and to correlate this proliferation potential with the radiographic features of these three pathoses. Materials and Methods : Immunohistochemical expression of PCNA, Ki-67, and cytokeratin as a proliferation marker were assessed for 15 cases of UA, 15 cases of DC, and 15 cases of OKC. The degree of immunochemical expression of three proliferation markers were correlated with the radiographic features, especially cortical expansion (negative and positive) and shape of border (scalloped and round). Results : Using PCNA and Ki-67, OKC showed the highest proliferation potential and UA the lowest. Statistically significant differences were found between the OKC and the UA (p.0.05). However, no statistically significant difference was present according to the radiographic features in all pathoses. Using cytokeratin, there was no significant differences of proliferation potential among three pathoses. Conclusions : OKC epithelium has the most intense proliferation potential, followed by the dentigeous cyst and then unicystic ameloblastoma. There is no significant relation between the radiographic features and the proliferation potential of epithelium of these three pathoses.
