In the dyeing of cotton and silk fibres using Caesalpinia sappan, the effects of pH changes of the Caesalpinia sappan dye liquor on the color were examined. In order to adjust the pH of the Caesalpinia sappan dye liquor, Schisandra chinensis extract and carboxylic acid were used for acidic condition, lye and the NaOH aqueous solution were used for alkaline condition. By introducing the dyeing method of pH adjustment, firstly, the effect on the reddish color inherent to the Caesalpinia sappan was examined. At the same time, the manifestation of the yellow color, which affect the manifestation of the red color greatly, was examined in detail quantitatively. By dyeing the cotton and silk fabrics, the inherent relationships established between the pH hanges and the fibre characteristics were sought to be examined.

Fay Elberta freestone peaches were harvested at four maturity levels as judged by skin color and firmness. They were ripened at $68^{\circ}F$ under 80 percent relative humidity for 4, 6, 8 and 10 days respectively prior to canning. Results indicate that both harvest maturity and ripening conditions are important factors influencing quality, flavor and composition of canned freestone peaches. Peaches harvested at $18{\sim}24$ pounds on a Magness-Taylor pressure tester with a 7/16' plunger(M1) failed to ripen satisfactorily. Fruits harvested at $13{\sim}17$ pounds (M2) pressure test ripened successfully at $68^{\circ}F$ within 6 to 8 days; and those harvested at 6 to 12 pounds (M3) needed 4 days for ripening at $68^{\circ}F$. Tree-ripened fruits (M4) were undesirable for canning because of the high percentage of bruised fruits. The optimum firmness for canning appears to be in the range of 1.5 to 3.0 pounds. The titratable acidity of peaches decreased during maturation and ripening. The tannin content of peaches at M1 maturity decreased with ripening at $68^{\circ}F$. But no appreciable change was observed in the M2 and M3 series which were ripened at $68^{\circ}F$ for 4 to 10 days. The volatile reducing substances (V.R.S.) increased as the peaches developed on the tree and also during post-harvest ripening. The effect of harvest maturity and post-harvest ripening on color grade of the canned peaches is presented. Little difference was found in the flavor and composition of peaches peeled by the cup-down lye peeling and the steam-peeling methods. The cup-down lye-peeling method might be most advantageous because of its higher peeling efficiency.

Water resource can be examined using biological sensors. Algae has been one of the biological sensors used to evaluate and monitor the water pollution. The monitoring system, however, could determine whether the examined water was safe or not. It needs additional expensive chemical test to figure out the cause of the water pollution. In this study, an endeavor is given to identify the toxicant in the water using the shape of the chlorophyll fluorescence induction curve(FIC) from algae using monitoring system. Fundamental curves are obtained from the experiments with specified amount of toxicant. Baysian method is utilized to determine the unknown toxicant in the water by comparing it with the fundamental curves. The results shows that the proposed method works fairly well.

The monitoring system, however, has not been used to determine what kind of the toxicological substance is in the water.

We have experienced fourteen patients of esophageal perforation at the department of thoracic and cardiovascular surgery, Chonbuk National University Hospital during the period from mar. 1980 to Oct. 1990. The ratio between male and female patients was 5 : 9, and their age ranged from 22 years to 69 years. The causes of th eesophageal perforation were iatrogenic in 6 cases, foreign body 5 cases, diverticulitis 2 cases, and postpneumonectomy 1 case. The locations were cervical esophagus in 2 cases, upper thoracic in 2 cases, mid-thoracic 4 cases, and lower thoracic 6 cases. The underlying diseases associated with perforation were lye stricture, diverticulum, achalasia, and postpneumonectomy empyema. The treatments were supportive in 6 cases and combined with surgical measures in 8 cases. surgical measurs were as follows : incision and drainage in 2 cases, esophagectomy with esophagogastrostomy 3 cases, esophagocardiomyotomy with partial fundoplication in 1 case, simple closure with myoplasty and thoracoplasty 1 case, and empyema drainage and gastrostomy 1 case. There was no mortality.

During a ten-year period from August, 1978 to September, 1989 45 patients with benign esophageal stricture were surgically evaluated. The results are as follows; l. Out of 45 patients, there were 26 males and 19 females ranging from 2 to 70 years of age with a mean of 31.9 years. 2. The most common cause of benign esophageal stricture was corrosive burn due to caustic agents[40 cases, 88.9 %]. Corrosive agents were 15 cases of lye, 22 cases of acid and 3 cases of other agents. Other causes were two cases of esophageal web and each one case of previous surgical result, inflammation and idiopathic mediastinal fibrosis respectively. 3. The most frequent stricture site was whole esophagus as 21 cases[46.7 %] and the next was lower a third thoracic esophagus[10 cases, 25.0%]. 4. In 33 of total 45 cases, colon interposition with right colon was performed without resection of the strictured esophagus except one case which was complicated esophageal cancer. Other procedures were 4 cases esophagogastrostomy with segmental resection, 2 cases of plastic repair and so on. 5. Major postoperative complications which were needed for secondary operation were 5 cases[11.1 %]. [2 cases of stenosis, ileus and ulcer bleeding respectively] Overall mortality rate was 4.4 %.

This study was conducted to identify an initial clinical experience of EMT students, so to better understand their' experience in clinical training. The subjects were 30 EMT students of C department of Emergency Medical technology in C city, who were demonstrating at the emergency room in C, T, S, W city. This study was approached by phenomenological method, collected data were analyzed by Colaizzi's method. the results were as a follows. From the protocol, significant statements were organized into 34 formulated meanings. from the formulated meanings, 21themes were identified, organized into 8 theme clusters, and then categories. EMT students got experienced 'tension resulting from new situation', 'fear in contacting with patients', 'lack of knowledge and skill', 'confidence feeling from being adapted', 'facing up to Paramedic role', 'experience of death' and 'stress'. The results of this study are to use as basic data for students attending clinical experience for the first time.

Purpose: The purpose of the study is to investigate the influencing factors of turnover intention in hospital paramedics. The factors included the job condition, job stress, and turnover intention. Methods: The subjects were 200 paramedics in hospital. Data were analyzed using frequency, t-test or one way ANOVA, Pearson's correlation, and multiple regression analysis with SPSS WIN 20.0 program. Results: Job stress was 3.59 points; job condition, 2.96 points; turnover intention 3.64 points. When the job stress was high, the satisfaction with job condition was very low and the turnover intention increased. When the job satisfaction was high, turnover intention decreased. factors affecting the turnover intention were annual income, turnover frequency, workload, and working department, role conflict, and personal relationship. Conclusion: It is necessary to establish the job description of paramedics and improve the working condition in the hospitals.

According to increase of personal incomes, spread of automobiles, a five-day only work week and expansion of cultural life, modern people today are increasingly showing leisure time interests. Under such social circumstances in which people's spare time are gradually increasing, weekend trips accompanied with hotel staying are increasing to a greater extent rather than one-day trips. In Korea where differences between regions and four seasons are remarkable, the resort industry has developed in harmony with seasonal environments and regional characteristics. In particular, an increasing number of modern people living in the wellbeing era tends to visit spa resort hotels for recreation and health. This study intends to compare realities of local and foreign spa resort hotels and investigate space characteristics of local spa resort hotels for promotion of use. In this study, it has been found that the proposed addition of characteristic-oriented spaces to the existing recreation, service and basic facilities beside the fundamental accommodations would be able to remarkably elevate use of the hotels.
