Yun Ti Wang studied medicine in England, different from other Korean medical doctors in early days. Yun, who entered medical school at Glasgow University in England in March 1919, graduated with a Bachelor of Medicine in October 1925, along with an England medical license. Yun began working as an instructor at Severance Medical College from November 1927, and received Doctor of Medicine from the College of Obstetricians and Gynecologists at Kyoto Imperial University in August 1936. After the Liberation, Yun began working as a faculty member at the medical school at Seoul University, and he also worked as a Chief of the Second Medical Clinic of the school from 1946. Yun made a great effort in order to build an integrated committee, eventually contributing to the launching of Joseon Medical Associates in 1947. He was also elected as a first president at Joseon Obstetrics and Gynecology Associates, which was organized at the same year as the Joseon Medical Associates. Yun entered military as an army surgeon in April 1949 and has worked there until he was appointed as a principal at the Army Medical School in September 1953. His contributions to the development of military medical services include the following: expansion of medical facilities in army, stable system of workforce in military medical service, launching of Medical Aid and establishment of Department of Medical Care, and introduction of new medical technologies in anesthesiology and neurosurgery, etc. The career of Yun can be largely divided into the field of gynecology and military medical services. In the gynecological field, Yun contributed to the settlement of obstetrics in Korea, by taking in charge of the obstetrics class at Severance following medical missionaries. As for the military medical services, he has contributed to the establishment of military medical system as well as to the opening of new academic areas. The impact of his activities on the establishment of military medical services is especially significant, since it was a field that no Korean citizens had access to during the colonization era.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

Chu Hyun Chik was one of those who graduated first from Jejungwon Medical School in 1908, and had carried on an independence movement as well as religious, educational, and social movement both as a doctor and a Christian. He opened the Inje Hospital in Sunchon, North Pyeongan Province in 1909, and was put in prison on charges of being involved in Incident of '105 People' as he joined in Sinminhoe in which christians(Christians) from Gwanseo showed their initiative. With 3.1 Movement as a momentum, he started to raise funds for an independence movement mainly in North Pyongan Province, as a councilor of the Ministry of Finance of Shanghai Provisional Government of Korea. After he moved into Andong, Manchuria, he continued to support the spread of an independence movement by connecting Shanghai Provisional Government of Korea with the country. In October, 1919, he came to Sanghai as an exile and lead diverse activities as a member of Shin Han young man party and one of the leading men of Korean Christendom, especially related to An Chang Ho and christians around him and joining in Hungsadan. In 1925 when he returned home, he opened the Dongje Hospital and devoted himself to the developments of religious, educational, and social movement as a president of YMCA, Sunchon and an executive of a branch of Suyang Donguhoe in Sunch'?n. By Incident of Suyang Donguhoe he was put in prison, resisting Japanese Imperialism and died in 1942.

This study was conducted to evaluate the sanitary performance and education of middle and high school foodservice employees in Seoul, South Korea in order to ensure the foodservice safety and identify why some employees cannot apply learned knowledge in real work situations. Subjects consisted of 217 school foodservice employees who attended a regular sanitary education program under the auspices of the Seoul Gangdong and Gangseo district offices. The sanitary performance was assessed with 5 dimensions (personal hygiene, ingredient control, process control, safety management and sanitary education), and was self-evaluated using a Likert 5 point scale. The data were analyzed using the SPSSWIN Version 12.0 package. The main results of the study showed that according to the general characteristics of middle and high school foodservice employees, 98.2% of respondents were women, and 64.1% of them aged 40-49. A total mean score of 5 items of sanitary performance for middle and high school employees was 4.74. Ingredient control field score was 4.83, process control 4.80 and personal hygiene 4.74. In contrast, the sanitary education field score was 4.56, significantly lower than the total mean score. Safety management field score was 4.71. Verbal education was the main method performed as a sanitary education in schools.

This study is basic research focused on product development and market activation based on analysis of current usage and demand for development of processed blue crabs. A total of 556 subjects aged 20s to 60s living in the Seoul area were surveyed. According to the survey, 65.1% of subjects consumed blue crabs at home, and 82% of them purchased blue crabs whole and undressed. Respondents gave higher marks to taste, nutrition, and texture compared to ingredient preparation, eating method, and price. Majority of blue crab consumers had no experiences of consuming processed blue crabs. Exactly 57.0% of consumers purchased them at big shopping centers, and the reason for purchasing was their good taste. When female consumers purchased processed blue crabs, they checked every part carefully compared to male consumers. Women gave high scores to blue crab powder, blue crab extract, blue crab croquette, and blue crab cake compared to men, demonstrating the necessity of developing processed blue crabs. Furthermore, the experienced processed blue crab group recognized the necessity of developing processed blue crabs compared to the inexperienced group. People showed significant differences in purchasing processed blue crabs according to gender as well as previous experience of blue crab consumption.

BACKGROUND: Color Doppler echocardiography is sensitive in detecting mitral regurgitation and useful in quantitating its severity. The presence of an eccentric regurgitant jet suggests that regurgitation is caused by prolapsing or flail leaflet of mitral valve. Until recently the direction of regurgitant jet in mitral valve prolapse has been examined in a single(parasternal short axis view) or orthogonal plane using color Doppler echocardiography, and few in the apical rotation method of a transducer. The purpose of this study was to clarify the usefullness of the apical rotation method of a transducer in detection of the direction of mitral regurgitant jet and diagnosis of the sites of mitral valve prolapse. METHODS: Twenty four patients(8 men and 16 women, mean age:47.3+/-18.8 years) with mitral valve prolapse with eccentric regurgitant jet were examined by two-dimensional and color Doppler echocardiograply using conventional parasternal long and short axis views, and four apical longitudinal planes(four chamber, vertical, two chamber and transverse views) obtained by the apical retation method of a transducer. RESULTS: Thirty one regurgitant jets were detected in twenty four patients, eighteen patients had anterior, nine patints posterior, and three patients bi-leaflet(anterior and posterior) prolapse. In eighteen patients with anterior leaflet prolapse, ten had medial, eight had middle, three had lateral, and three had two portions(two, medial and middle; one, middle and lateral) prolapse. In nine patients with posterior leaflet prolapse, five had medial, three had middle, two had lateral, and one had two(medial and middle) scallop prolapse. CONCLUSION: Color Doppler echocardiography by the apical rotation method of transducer is useful in assessment of the site of prolapse in patients with mitral valve prolapse with eccentric regurgitation.
