The autoclave method and the traditional cooking method were compared for nutrients (especially. minerals). color difference, viscosity, reduction of sugar and amino nitrogen content of brown stock. The autoclave cooking method is better than the traditional cooking method for retaining protein and amino nitrogen contents, as well as for reducing sugar content. Also, reducing sugar content increased by the autoclave cooking method. Since the color of brown sauce was related with the reducing sugar content, the autoclave cooking method was more effective than the traditional cooking method for the color development of brown stock. Since the autoclave method can reduce the cooking time without a loss of quality in brown stock, the autoclave method is a viable alternative to the traditional method of preparing brown stock.

This study has been conducted to develop brown stock with the high pressure cooking(HPC) method. The sterilization methods, package film and storage methods, and quality maintenance during storage were investigated in this study. The packaging quality of NY/PP was inferior to that of PE/AU/PP since NY/PP facilitated the ventilation and moisture absorption. The maximum duration of the safe storage was found to be 50 days at 25℃, 30 days at 35℃ for NY/PP package film, and 60 days at 25℃, 40 days at 35℃ for PE/AU/PP one. These results showed that the overall quality of brown stock by the HPC method was not different significantly from that of brown stock by the traditional approach. Furthermore, the HPC approach might improve the productivity by saving the labour cost, food cost, and cooking time. Therefore, the traditional method might well be substituted by this newly developed method.

University students are likely to be price sensitive in terms of consuming foods. furthermore, they tend to experience irregular meal time, overeating, excessive drinking and smoking. These undesirable habits might be able to lead to nutrition imbalance. In this regard, the authors intend to identify the food consuming style and habits of Kyongju university students. 225 questionnaires were distributed to the students and 199 out of the total (88.4% response rate) wear returned. The main research findings can be summarized as follows, 53.3% out of the total take meals twice a day and 89.9% responded that their meal time is irregular, which implies they are not aware of the importance of nutrition balance and they are probably not in good health. In addition, students prefer cookies and sweets followed by fried stuffs as a snack while they are willing to drink fruit juices and cokes as a beverage. In terms of alcohol drinking and smoking, it is turned out that 47.9% drinks once or twice a month and 24.9% are smokers. Interestingly, the female students outnumbered the male students in terms of the quantity of consuming alcohol. Approximately, half of the total respondents replied that they are not confident of whether they are in good health. This study suggest that students must recognize the importance of nutrition balance and a proper education must be provided to help the students understand it.

Hot corrosion behavior of the CMSX-2, CMSX-4, Rene 77, Rene 80 Ni-base superalloys was investigated at 900℃ by two different corrosion methods, immersing the samples in Na2SO4-NaCl mixture(immersion test)and coating the salt mixture on the surface of the samples(modified coating test). The effects of corrosion times and salt compositions from 0 to 100 percent in Na2SO4-NaCl mixtures were examined. Experimental results showed that the corrosion depths in the alloys increased with increasing time, and the depths of the modified coating test were shotter than those of the immersion test in the mixed salt. It was found that the depths of CMSX series alloys increasing NaCl contents in the mixtures up to 50% NaCl. Corrosion products of the alloys were composed of Cr, Al, Ti oxides. The oxide scale, such as Cr₂O₃, Al₂O₃, TiO₂, were shown to improve hot corrosion resistance in the fused Na₂SO₄-NaCl mixtures.

Rather than focusing on the general recognition of the area and extensive preference about its native cuisine, this study carried out more practical examination on the recognition of the native cuisine by presenting the more detailed introduction of the native cuisine in Hadong area. The findings of this study can be used as basic materials to devise measures for the instillation and advertisement of Hadong area's image, the development and maintenance of its native cuisine benefiting the activation of the local economy, and the reestablishment of Hadong area's native cuisine culture. First, the overall recognition of Hadong area's native cuisine was low and more consumption needs to be boosted by merchandising its foods through the strengthening of recognition. Second, correlation between this area's native cuisine was revealed and tables need to be set and menus need to be organized with this correlation in mind. Basic materials for suggestion sale were garnered. Third, given that most outside tourists visit Hadong by word mouth of all the information sources available, it is highly likely that positive word of mouth through satisfaction with native cuisine will raise the overall recognition of the area. Fourth, precise subdivision market and target market need to be specified. Though the factors like economic costs and the time required cannot be overlooked in strengthening recognition, consistent advertisement to the middle-aged people who are over 40 and live in Kyungsang-Do area will contribute to the fast rise in the recognition of Hadong area's native cuisine, leading to the possibility of economic development in the process.

Background: Dendritic cells (DCs) are rare leucocytes that are uniquely potent in their ability to capture, process and present antigens to T cells, and so selectively migrate through tissues to reach lymph nodes and spleen where initiation of immune responses takes place. It has been reported that a dense infilteration of dendritic cells correlates with a favorable prognosis in several types of cancer. A similar correlation also has been noted in patients with papillary carcinoma of thyroid. The purpose of this study is to determine whether DCs are generated from peripheral blood monocytes by using cytokines such as GM-CSF, TNF-α, and IL-4 and whether cytotoxic T cells activated by DCs attack the papillary carcinoma tissues. Methods: Peripheral blood was obtained from 2 patients with thyroid papillary cancer. DCs were established from monocytes by culturing in the presence of GM-CSF, Flt-3 ligand. TNF-α , and IL-4 for14 days. At day 14, expression of surface markers typical for DCs was analyzed morphologically. The immunophenotypic features of DCs such as CDla, CD83, and CD86 were analyzed by phase contrast microscopy. At day 15 DCs were incubated with thyroid cancer tissues and normal thyroid tissues for 7 days. Results: DCs were generated from the peripheral blood monocytes. The generated cells had the classic morphology of DCs. Activated cytotoxic T lymphocytes (CTLs) were observed. Veiled cell known as circulating DCs attached to the thyroid cancer tissues were observed. The CTLs activated by DCs were observed to attack the papillary carcinoma tissues by scanning electron microscope. However, normal tissues were not attacked by CTLs. Conclusion: DCs can be generated from the peripheral blood monocytes. Futhermore, the CTLs activated by DCs also can attack the papillary carcinoma tissues. These results that DCs can be used as adjuvants for adoptive immunotherapy of papillary thyroid cancer.

In Korea, EMT have two classified subgroup of first and second degree : EMT-P, and EMT. For the beginning, authorization of the first EMT was made in this year through the EMT educational program. There are 8 items which EMT can perform the treatment without the supervision by a physician. But there was no previous report of pertinent assesment of treatment performed by the EMT. There upon authors have conducted review of assessment done by the EMT in EC setting, and proposed the following treatment application can be used by EMT at the field of accident. The study materials include adult trauma patient older than 15 years, and sustained trauma within 48 hours before visiting Ewha University DongDaeMoon Hospital Emergency Deparment. The duration of study was from Apr. 1 1995 to Aug. 31 1995. the study was conducted by 5 certified EMT. The EMT's performance was evaluated by the attending Emergency Medicine physician. The result were as followings ; 1. Among the total 5532 ED visiting patients during the study period, 1267 were adult trauma patients who recieved treatment within 48 hours of injury. 2. Among 1222 out of 1267 patients have completed performed survey. 3. Male to female ratio was 2.6 : 1, age distribution was from 15 to 87 years old and mean age was 34.6 years old. 4. The MOI showed : MVA (33.1%), blunt trauma (29.9%), slip down (16.8%), penetrating injury(15.4%), and miscellaneous (5.7 %), burn (3.1%), falling down injury(2.9 %), bite injury(1.1%) in order. 5. There were 437 cases of survey completed by the EMT. For assessment of mental status of 3 different method : AVPU, 5 scale mental status and GCS, were correlated with EM physician with 99.1%, 98.6%, 97.7 %, respectively. 6. For 320 out of 437 cases of survey completed, 319 patients recieved treatment by the EMT within 30 minute and 1 patient between 30 to 60 minute of an ED arrival. 7. For those 437 cases of survey completed, 266 patient (60.9%) had adequate treatment and 54 patients (12.4%) had inadequate treatment. 67 patient (15.3%) did not received treatment but it was adequate inway, and 50 patients (11.9%) did not received treatment even though patient required treatment. In cases of adult trauma patients, EMT's mental status assessment was correlated with EM physician's assessment. But treatment done by EMT without the supervision of EM physician was adequate only in 76.2 %. Therefore, continuous education and assessment of treatment performed by EMT in needed to improve field treatment by EMT future.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.
