The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice by instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min, correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=.000) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).

Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

Objective : Neijingshiyifanglun with additions and emendations was written by Liu Yude, a doctor who lived during Ming period. I researched the origin of the book, and analyzed the features of it as well. I also approximated his birth date and death date. In doing this, I gained a better understanding the practice of medicine in ancient China. Method : I researched the book by comparing its contents, including the causes of diseases, the descriptions of symptoms, the transmissions of diseases, and treatments, with other sources that he had referenced. Result : In understanding Hwangdineijing, Liu Yude was influenced by many medical scholars such as, Wang Bing, Ma Shi, and Wu Kun, but his opinion is most similar to that of Zhang Jiebin. In the field of the Chinese Medical Theory, he was deeply influenced by 'JinYuan-Sidaijia's theories, particularly Li Gao and Zhu Zhenheng. In fanglun, he was greatly influenced by Yifangkao. He concluded that 'aggregationaccumulation' was a disease of stuffiness, and suggested its cure in through 'yangjingzezichu' and 'treatment of blood aspect'. He recognized the disease of 'reversal of qi' as the disease of 'jiaoqi'. He also indicated that the word of 'qi' is not 'rough' but 'tears' or 'yingfengliulei'. Conclusion : 1. He was an excellent medical practitioner and scholar in the history of oriental medicine. 2. He found and corrected errors in the opinions of Wang Bing, Ma Shi, and Wu Kun. 3. He frequently practiced Taipinghuiminhejijufang, and considered Spleen-Stomach, yin-blood, and fire-heat important. 4. He captured the spirit of Huangdisuwenxuanminglunfang, Neijingshiyifanglun, Yifangkao in views of remedy and theory. 5. Neijingshiyifanglun with additions and emendations is the most comprehensive book about fanglun because of its thorough analysis of the Hwangdineijing and its connection to the treatment of ancient diseases in Oriental Medical History.

The records of 10 patients with traumatic diaphragmatic hernia seen from November 1977 through July 1987 were reviewed. All the patients had a transdiaphragmatic evisceration of abdominal contents into the thorax. We treated 7 male and 3 female patients ranging in age from 3 to 62 years. In 8 patients, diaphragmatic hernia followed blunt trauma and in 2 patients, stab wounds to the chest. The herniation occurred on the right side in 3 patients and on the left side in 7. All the patients sustained additional injuries: rib fractures [7 patients], additional limb, pelvic and vertebral fractures [6], closed head injury [2], lung laceration [1], liver laceration [1], renal contusion [1], ureteral rupture [1], and splenic rupture [1]. Organs herniated through the diaphragmatic rent included the omentum [6 patients], stomach [4], liver [4], colon [3], small intestine [1], and spleen [1]. For right-sided injuries, the liver was herniated in all 3 patients and the colon, in 1. in the initial or latent phase, dyspnea, diminished breath sounds, bowel sounds in the chest were noted in 4 patients, and in the obstructive phase, nausea, vomiting, and abdominal pain were found in all 3 patients. Two patients had a diagnostic chest radiograph with findings of bowel gas patterns, and an additional 8 had abnormal but nondiagnostic studies. Hemothorax, pleural effusion or abnormal diaphragmatic contour were common abnormal findings. Three patients were operated on during the initial or acute phase [immediately after injury], 4 patients were operated on during the latent or intermediate phase [3 to 210 days], and 3 patients were operated on during the obstructive phase [10 to 290 days]. Six patients underwent thoracotomy, 2 required thoracoabdominal incision, and 2 had combined thoracotomy and laparotomy. Primary suture was used to repair the diaphragmatic hernia in 9 cases. One patient required plastic repair by a Teflon felt. Empyema was the main complication in 2 patients. In 1 patient, the empyema was treated by closed thoracostomy and in 1, by decortication and open drainage. There were no deaths.

The comparative feeding ecology of greenling Hexagrammos otakii and Schlegel's black rockfish Sebastes schlereli populations was investigated in the Jangbong tidal flat near Incheon, Korea. Monthly samples were taken using a modified otter trawl from November 1999 to January 2001. The stomach contents of 124 greenling and 115 Schlegel's black rockfish were analyzed. The diet of H. otakii was dominated by the amphipods Gammaropsis iaponicus, Caprella scaura, Isaeopsis sp. and Monocorophium acherusicum, the shrimps Latreutes mucronatus and Alpheus japonicus, the mysid Neomysis orientalis and the bivalve Mytilus edulis. In contrast, S. schlegeli mainly fed on the mysids N. orientalis, N japonica, and N. awatschensis, the shrimps Exopalaemon carinicauda, A. japonicus and L. mucronatus, and the fish Pholis fangi and unidentified gobiids. A comparison of the frequency and abundance of food items showed that crustaceans (e.g. amphipods, mysids and shrimps) were important foods for both species. Their main dietary components, however differed which is probably due to differences in the spatial distribution of the two species and their prey items. In conclusion, greenling and Schlegel's black rockfish, despite being sympatric on a tidal flat have distinct food habits and low dietary overlap (Schooner's index: 0.1). These results indicate, to some extent, resource partitioning for the maximum utilization of available foods in the tidal flat.

This current study investigated the anti-ulcer activity of 2 types of virgin coconut oil (VCO-A and VCO-B) and coconut oil (CO). Sprague-Dawley of male rats divided into 6 groups and each group consisted of ten rats. Rats were then treated with either VCO or CO and then were then anaesthetized and pyloric ligation was performed. The anaesthesia was discontinued and the animal usually recovered consciousness within less than an hour. Three hours later, the animal was then again anaesthetized and sacrificed with chloroform. Stomach removed and its content subjected to measurement of volume and pH. The results revealed VCO-B and VCO-A (100%) significantly inhibited (p < 0.001) the volume of gastric juice secreted by the control rats by 66.81% and 51.53%, respectively. Followed by CO 42.80%. While the inhibition of gastric juice for positive control rats which treated with ranitidine (100 mg/kg) was only 22.38%. The total acid output was reduced by the oils to 70.80%, 74.16% and 40.45% for VCO-A, VCO-B and CO respectively compared to control group. Ranitidine reduced the total acid output by 34.83%. In conclusion, prevention of gastric lesions in rats by VCO was found to increase the mucous and decrease the acid volume, total acid contents and ulcer scoring. The treatment of VCO affects the all parameters that influence the initiation and perpetuation of ulceration.

Feeding habits of Favonigobius gymnauchen collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. Favonigobius gymnauchen was a carnivore which consumed mainly gammarid amphipods, polychaetes, crabs and copepods. Its diets included minor Quantities of gastropods, tanaids and isopods. It showed ontogenetic changes in feeding habits. Small individuals (1$\~$2 cm) fed mainly on gammarid amphipods, polychaetes, and copepods. While the portion of the stomach contents attributable to polychaetes and crabs increased steadily with incensing fish size, consumption of copepods decreased progressively. Gammarid amphipods were the most selected prey item for all size classes. Although gammarid amphipods, polychaetes, crabs and copepods were major prey organisms for all seasons, the relative proportion of these food items changed with season. Consumption of copepods was relatively high in spring and fall and consumption of gammarid amphipods, polychaetes and crabs was relatively high in summer.

The feeding habits of sandfish, Arctoscopus japonicus were studied by examining the stomach contents of 2,115 specimens collected between April 2003 and March 2004 in the East Sea of Korea. The standard length (SL) of the specimens ranged from 9.8 to 22.9 cm. The main prey items of A. japonicus were amphipods, mysids, cephalopods and fishes. They showed ontogenetic changes in feeding habits. Individuals of small size (9~16 cm, SL) fed mainly on small prey organisms such as mysids and amphipods. However, more cephalopods and fishes were consumed with increasing fish size (16~23 cm, SL).

Population ecology of Abbottina springeri has been investigated from March to November, 1995 at Musimchon stream of Kadok-myon, Chongwon-gun, Chungchongbug-do. The favorite habitat was a sluggish area with muddy bottom, but larger individuals more than 60 mm in total length were also collected at rapids of low velosity. Judging from the total length frequency in this population on June, total length 30~50 mm group is one year old, 50~65 mm group is two years old, and longer than 65 mm is regarded over three years old. Sexual dimorphism was revealed conspicuously in genital papilla, nuptial tuberles and nuptial pigmentation in the males at spawning season. Peak season of spawning was June when the water temperature reaches $20\sim25^{\circ}C$ and they start spawning at the age of two. The sex ratio of female to male was 1:0.93. The mean of egg number and egg size in ovary were 652 and 0.43~0.06 mm respectively. According to the contents of stomach, this species feeds mainly on botton algae at all ages and some aquatic insects in adult.
