본 연구는 수온 24℃에서 체중 0.6-786 g 범위의 참돔 52개체의 SMR을 측정한 후 점진적인 저산소 조건에 노출시켜서 S_crit를 측정하여 개체 크기에 따른 저산소 내성을 평가할 목적으로 실시하였다. SMR (mg O₂ kg^-1hr^-1)은 SMR=351.59·W^-0.195 (r²=0.934, p<0.001)의 관계식으로 표시할 수 있었고, 체중(W) 증가에 따라 감소하는 경향을 보여주었다. 참돔의 체중과 S_crit 사이에는 S_crit (%)=2.316·logW+17.805 (r²=0.682, p<0.001)의 회귀직선식으로 나타낼 수 있었고, 체중 0.6-786 g인 개체의 S_crit는 17.3-24.4% 범위에서 개체 크기가 클수록 증가하여 작은 개체가 저산소 내성이 높은 것으로 나타났다.

백편을 만들때 멥쌀가루 100에 찹쌀가루를 총중량의 0%, 5%, 10%, 15%, 20%, 25%, 30% 첨가하고 저장시간 0시간, 24시간, 48시간, 72시간 저장한 후($4^{\circ}C$ 에서) reheating한 백편의 기호성과 조직감(Textur) 에 어떠한 영향을 끼치는 가를 관능검사와 기계적 검사에 의해 측정한 결과를 다음과 같이 요약할 수 있다. 1. 관능검사 결과 백편의 Color는 찹쌀의 첨가량이 증가할수륵 누런색이 짙어졌으며, 24,48,72시간 저장 한 후 reheating한 백편도 누런색이 짙어지는 경향을 나타냈다. Coarseness는 찹쌀의 첨가량이 증가할수록 증가하는 경향이었으나 저장전의 백편은 유의적인 경향을 나타내지 않았다. 찹쌀의 첨가량이 증가할수륵 Softness, Dryness, Crumblyness는 감소경향을 나타냈으며 24,48,72시간 저장한 후 reheating한 백편도 유의적인 감소청향을 나타냈다. 외관의 기호도는 찹쌀의 첨가율이 5%인 백편을 가장 좋아했고, 조직감 및 종합적인 기호도는 찹쌀의 첨가율이 $10{\sim}20%$인 백편을 좋아했다. 2. Rheometer에 의한 백편의 Texture는 찹쌀의 첨가량이 증가할수록 Compression force, Gumminess, Chewiness가 증가하는 경향을 나타냈다. 24,48,72시간 저장한 후 reheating한 백편은 저장전보다 점점 감소경향을 나타했다가 72시간 저장한 후 reheating하면 다시 증가경향을 나타했다. Work ratio 및 Recovered height는 찹쌀의 첨가량과 저장근간의 변화에 크게 영향을 미치지 않았다. Reheating하지 않고 0,24,48,72시간 저장한 백편의 Compression force는 찹쌀의 첨가량이 증가할수륵 증가경향이 켰고 저장시간이 경과함에 따라 Compression force가 증가하였는데 특히 24시간 저장하는 동안 급격히 증가하였다. 3. 찹쌀 첨가량이 증가할수록 수분함량은 증가하였고, 저장시간이 경과함에 따라 수분함량은 감소경향을 나타냈으나 24시간 저장한 후 reheating한 백편만이 수분함량의 증가경향을 나타했다. 4. 백편의 Softness는 Compression force 및 Work ratio와 유의적인 상관관계를 나타내었으며, Dryness와 Crumblyness는Work ratio와 유의적인 상관관계를 나타내고 있어 백편의 조직감은 Compression force 와 Work ratio로 대치할 수 있을 것이라고 사료된다. 수분함량은 기계적 검사보다 관능검사와 더욱 높은 상관관계를 나타냈다.

Purpose: Data on the relationship between gastroesophageal reflux (GER) and brief resolved unexplained events (BRUE) in infants is scarce. The aim of this study was to identify the characteristics of combined multichannel intraluminal impedance-pH (MII-pH) monitoring in infants who have experienced BRUE. Methods: We conducted a prospective study of infants who were hospitalized on account of BRUE and required 24-hour MII-pH monitoring. Results: Twenty-one infants (mean age, 4.7 months; range, 0.9-8.9 months; male/female, 11/10) participated in this study. BRUE symptoms associated with GER were found in 10 infants (47.6%). Based on the RI on pH-metry alone, only 7 (33.3%) infants were diagnosed with GERD. More than 100 GER episodes detected by MII were found in 10 (47.6%) infants. Nineteen percent of infants were diagnosed with GERD based on both pH and MII. Conclusion: Both acid and non-acid reflux seem to play a significant role in the pathogenesis of GER-related BRUE in infants.

This study examined the reproducibility of nutrient intakes estimated by the 24-hour recall method in a prospective cohort study (Longitudinal study of aging and health monitoring of Korean elderly) of middle-aged volunteer subjects (42 males and 49 females) in the Seoul area. The three-day 24-hour recall was administered twice at an interval of approximately 6 months. The first data were collected and a corrective procedure was performed by interviewing of the subjects and a trained dietitian. The second data were collected by mail from the subjects without the performance of any corrective procedure. The mean age of the subjects was 53.5 $\pm$ 9.6 for the males and 52.2 $\pm$ 8.9 for the females. The subjects who had above college education were 95% in the case of the males and 60% in the case of the females. The characteristics of the male subjects in this study were that they were highly educated and held professional jobs and were from the middle or upper class. Comparing the first and second 24-hour recall data, the second data showed relatively lower intakes of all nutrients, except vitamin A, vitamin Bi and cholesterol. There was no difference in the nutrients of the first and the second data with respect to vitamin A, vitamin B$_1$ and cholesterol in the males and calcium, iron, sodium, vitamin A, vitamin B$_1$, vitamin B$_2$ and cholesterol in the females. This data may indicate that the 24 hour retail method without a dietitian's help may result in lower reporting of the subject's intakes. The men had a tendency to remember less than the women. Pearson's correlation coefficients with unadjusted nutrient intakes values were ranged from 0.24 to 0.66. When energy intake was adjusted, there was a slight increase (from 0.26 to 0.71). Intra-class correlation coefficients with nutrient-unadjusted values ranged from 0.22 to 0.66, and the energy-adjusted values were ranged from 0.23 to 0.69. The weighted Kappa statistical values ranged from 0.10 to 0.40. On the average,46.3% of the subjects who were found in the lowest quartile of the nutrient intake levels based on the first 24-hour recall, were in the lowest quartile based on the second 24-hour recall. Therefore, there was a low reproducibility between the first and the second 24-hour recall. We should examine the factors influencing low reproducibility. Also, strategies should be developed to maximize the reliability of the assessment, with regard to portion-size training and telephone validation. (Korean J Community Nutrition 8(4) : 603∼609, 2003)

The purpose of this study was to identify the relationship between mother's interactive responsiveness and infant's communication. The participants of this study were 64 pairs of infants aged 13 to 24 months and their mothers. The infants' communication and their mother's interactive responsiveness were observed during mother-infant's free play for 10 minutes. The mother's interactive responsiveness was analysed on the basis of turn-taking and gaze. The collected data were analyzed by one-way ANOVA and Pearson's correlation. It was found that the communication of infants aged 13 to 24 months developed rapidly with a certain tendency. Mothers' interactive responsiveness increased significantly with infants' age group. The relationship between mother's interactive responsiveness and infant's communication was significant.

Objectives : We investigated genetic toxicity of HMCO5 in relation to chromosome aberration test on Cultured Chinese Hamster Lung (CHL) in the presence and absence of S-9 mix. Methods : Experimental groups were divided into two groups: with S-9mix (+S) or without S-9 mix (-S). -S group was also divided 2 series by treatment hours (6 hr: 6-S; or 24 hr; 24-S). Each group treated with vehicle only (complete culture medium), HMCO5 (1,250, 2,500, $5,000\;{\mu}g/ml$), and cyclophosphamide monohydrate (CPA) and ethylmethanesulfonate (EMS), respectively. Results : HMC05 did not show any aberrant metaphase. However, there were significant (p < 0.01) aberrant metaphases with CPA in S+ and with EMS in S-. Conclusions : These results indicate that HMC05 formula does not show any toxicity in chromosome aberration test.
