The aim of this study was to provide nutrition information to consumers by analyzing crude fat, saturated and trans fatty acids in commercial retort foods (n=70). The following sauce products of curries (n=21) and black-bean-sauces (n=16), other sauces (n=17) and instant cooking foods (n=16) were collected. Crude fat contents were quantified with the Rose-Gottlieb method using acid digestion. While saturated and trans fatty acids were examined by gas chromatography with a flame ionization detector (FID). Crude fat, saturated and trans fatty acid content ranges were $0.47{\pm}0.42{\sim}12.80{\pm}0.07g/100g$, $0.24{\pm}0.02{\sim}17.41{\pm}0.41g/100g$, $0.00{\pm}0.00{\sim}0.46{\pm}0.05g/100g$, respectively. Maximum recovery of analysis values was crude fat (119.7%), saturated fat (119%) and trans fatty acid (90%) compared the actual amounts based on the reference value indicated on the nutrition label. The analyzed samples were found to be compliant with nutrition label standard, because the contents of crude fat, saturated fatty acid, trans fatty acid were less than 120% of the reference value indicated on the nutrition label in retort foods. Therefore, the nutrition information on retort foods available to consumers was found to be trustworthy.

Natural killer (NK) cells play have a crucial role in the early phase of immune responses against various pathogens. We compared characteristics of canine NK cells against two canine mammary carcinoma cell lines, REM134 and CF41.Mg. REM134 showed higher expression of progesterone receptor, proliferative cell nuclear antigen, Ki67, multiple drug resistance, Bmi-1, c-myc, E-cadherin, and human epidermal growth factor receptor type-2 than that of CF41.Mg. For specific expansion and activation of NK cells, we isolated CD5 negative cells from canine peripheral blood mononuclear cells and co-cultured K562 cells in the presence of interleukin (IL)-2, IL-15, and IL-21 for 21 days. As a result, we found that expression markers of activated NK cells such as NKp30, NKp44, NKp46, NKG2D, CD244, perforin, granzyme B, and tumor necrosis factor alpha were highly upregulated. In addition, we found there was upregulated production of interferon gamma of activated NK cells against target cells such as REM134 and CF41.Mg. Specifically, we observed that cytotoxicity of NK cells against target cells was more sensitively reacted to CF41.Mg than REM134. Based on the results of this study, we recommend the development of an experimental application of CF41Mg, which has not been reported in canine mammary carcinoma research.

Firefighting hoods protect the head, face, and neck areas of officials while they perform firefighting services. The purpose of this study is to investigate the head size of Korean firefighting officials in order to establish the dimensions necessary to construct firefighting hoods. A total of 98 male firefighting officials participated in this study and 11 body dimensions, necessary for the construction of firefighting hoods, were measured. The data collected from the firefighting officials were compared to the general adult male data from the Size Korea national anthropometric study. The heights, weights, head circumferences, head heights, and bitragion arcs of the firefighters were significantly larger than those of general adult males, which shows that firefighting officials generally have larger body and head sizes than general adult males. Based on the results of Pearson's correlation coefficients, head circumference and head height were judged to be the important measurements for the construction of the firefighting hoods. Thus, these two measurements were chosen as the basic dimensions of the cross tabulation analysis. As a result, head circumferences of 57.00~60.99cm and head heights of 23.00~25.99 cm were found to be important measurement ranges among the firefighters. This study is expected to be used as the basis for the creation of firefighting hoods that help to ensure the safe rescue activities for firefighting officials.

목 적: 병적 위식도 역류 환자에서 후두인두부 산도를 검사하여 후두인두부 역류와 호흡기 증상과의 상관관계를 연구하고자 하였다. 방 법: 2003년 2월부터 2004년 9월까지 잦은 구토 등 위식도 역류가 의심되는 증상이 있거나 만성 재발성 호흡기 증상이 있어 24시간 후두인두부와 식도에서 산도 검사를 실시한 39명 중 병적 위식도 역류를 보인 29명을 대상으로 하였다. 병적 위식도 역류의 기준은 95백분위수 이상 역류 지표를 병적 역 류로 정의하였고, 후두부 인두 산 역류의 기준은 식도에서 pH 4 이하로 떨어짐과 동시에 후두부 인두에서 pH가 4 이하로 떨어지는 것으로 정의하였다. 결 과: 1. 산도 검사를 실시한 39명에서 호흡기 증상이 있는 7명 중 6명(86.%), 호흡기 증상이 없는 32명 중 23명(72%)에서 병적 위식도 역류를 보였다. 2. 호흡기 증상으로는 반복되는 폐렴 2명, 크룹 1명, 후두연화증 1명, 천식 2명 등이었다. 3. 호흡기 증상을 동반한 병적 역류군에서 후두인두부와 식도의 역류 지표를 비교하면 5분 이상 지속된 역류의 횟수 제외한 역류 지수, 총 역류 횟수, 최 장 역류 시간 등에서 통계학적으로 의의있는 차이를 보였다. 4. 호흡기 증상을 동반하지 않은 병적 역류군에서 후두인두부와 식도의 모든 역류 지표들이 유의한 차이를 보였다. 5. 식도에서 호흡기 증상을 동반한 병적 역류군과 호흡기 증상을 동반하지 않은 병적 역류군의 역류지표를 비교하면 총 역류 횟수를 제외한 역류 지수, 최장 역류 시간, 5분 이상 지속된 역류의 횟수에서 통계학적 의의가 없었다. 6. 후두부 인두에서 호흡기 증상을 동반한 병적 역류군과 호흡기 증상을 동반하지 않은 병적 역류군의 역류 지표를 비교하면 모든 항목에서 통계학적 의의가 없었다. 결 론: 병적 위식도 역류 환자에서 호흡기 증상 유무와 관계없이 후두인두부의 산도 검사 결과는 통계학적 의의가 없으므로 만성 호흡기 질환에서 후두인두부 역류와의 상관관계의 규명에 후두인두부 산도 검사의 유용성에 대한 재고가 필요하다. Purpose: The aim of this study was to evaluate the significance of pH monitoring at two levels, hypopharynx and esophagus in gastroesophageal reflux. Methods: 29 patients with pathological gastroesophageal reflux were classified into two groups: Group I had recurrent respiratory symptoms and Group II had not recurrent respiratory symptoms. The ambulatory pH monitoring was performed at the hypopharynx and the esophagus simultaneously with two channel catheter for 18~24 hr. The pathological reflux was defined when the percent of time that pH was below 4.0 exceeding the 95th percentile of normal value. Hypopharyngeal reflux was defined as the pharyngeal pH drops below 4. Results: 39 patients were performed pH monitoring at the level of hypopharynx and esophagus for 24 hours. Among 7 patients with chronic respiratory symptom, 6 patients (85.7%) have pathological esophageal reflux. Among 32 patients without chronic respiratory symptom, 23 patients (71.8%) have pathological esophageal reflux. Thus 29 out of 39 patients (74%) have pathological esophageal reflux. In the Group I, all parameters except the longest episode showed significant differences between hypopharyngeal and esophageal pH monitoring. None of parameters showed significant differences between group I and II in the pharyngeal pH monitoring. Conclusion: Regardless of presence of respiratory symptoms, the pH monitoring at the pharyngeal level in patients with gastroesophageal reflux did not showed any differences compared with the esophageal pH monitoring. Therefore we may reconsider the usefulness of hypopharyngeal pH monitoring in patients with chronic respiratory symptoms.

The monolayer engineering diamond particles are aligned on the oxygen free Cu plates with electroless Ni plating layer. The mean diamond particle sizes of 15, 23 and $50{\mu}m$ are used as thermal conductivity pathway for fabricating metal/carbon multi-layer composite material systems. Interconnected void structure of irregular shaped diamond particles allow dense electroless Ni plating layer on Cu plate and fixing them with 37-43% Ni thickness of their mean diameter. The thermal conductivity decrease with increasing measurement temperature up to $150^{\circ}C$ in all diamond size conditions. When the diamond particle size is increased from $15{\mu}m$ to $50{\mu}m$ (Max. 304 W/mK at room temperature) tended to increase thermal conductivity, because the volume fraction of diamond is increased inside plating layer.
