  • 남자고등학교 교실에서 발생하는 냄새(발냄새, 머리냄새, 쉰냄새, 땀냄새)와 대표악취물질(부티르산, 암모니아)에 대한 뇌파반응을 분석하였다. 냄새자극 시험은 30~50대의 여성을 대상으로 수행하였다. 교실냄새와 대표악취물질의 자극에 대한 뇌파 지표들의 변화 경향은 측두엽에서 가장 두드러지게 나타났다. 이들 악취물질의 측두엽에서 반응은 바탕뇌파대비 상대알파파를 0.04~0.13 감소시켰고, 상대베타파 0.02~0.06, 상대감마파를 0.03~0.09 증가시켰다. 교실냄새들과 두 악취물질들은 이완상태를 나타내는 알파파를 감소시켰고, 각성과 긴장 및 스트레스를 나타내는 고베타파(18~30Hz)와 불안과 흥분상태를 나타내는 감마파(30~50Hz)를 활성화시켰다. 냄새물질들의 뇌 각성 및 자극정도는 머리냄새 > 부트르산 > 발냄새, 쉰냄새 > 암모니아> 땀냄새 순이었다. 이러한 결과는 교실냄새가 과도한 각성이나 긴장을 유발하므로 수업 집중력이나 학습능력을 저해할 수 있음을 의미한다.

  • The objective of this study is to find out the effect of yeast on hair loss treatment and the role of hair follicle stem cell activator, which is important in hair growth. The authors have recently produced a substance, which has no disgusting odor, does not precipitates and does not easily corrupt, to use instead of yeast acquired from raw rice wine(Makgeolli). The substance is named Yeast Constituent Extract(YCE). In this research, the Produced YCE was applied on the hair loss area of 10 Androgenic alopecia patients, twice every day for 6 months, in order to test the effect of hair loss treatment and the role of stem cell activator. As a result, all of the patients showed a significant growth of hair after 3 months of test, and showed much more growing, thickening and strengthening of hair after 6 months. As a result of measuring the number of hair strings in the same scalp region of the patients after 6 months, it is found that the density of hair has increased, indicating that the hair loss treatment was effective. Also the hair follicle stem cell was isolated from the patients and the contents of growth factors (IGF, VEGF, FGF, HGF) derived from hair follicle stem cell were measured with ELISA. As result, the amount is found to be about 10 times greater than before the test. The hair follicle stem cell contains many growth factors that affect growth of hair, so it takes a highly important role in hair loss treatment. The YCE that the authors have produced was found to be effective in increasing the contents of growth factors that are derived from hair follicle stem cell. Thus it can be inferred that the YCE plays a role as a stem cell activator that activates the hair follicle stem cells. In conclusion, the YCE is considered to be highly effective for hair loss treatment and to have a role as a stem cell activator.

  • The purpose of present paper is to compare and analyze the quality of imported Chinese products with the Korean local products in terms of proximate composition, character of external appearance , ingredient composition of dried bracken , dried radish cubers, meju , dried pollack, dried mussel , and dried brown seaweed(Undaria puinnatidifida) which were imported between Oct., and Dec. 1992 and distributed in the market. Moisture recovery of dried products resulted in changed shape and incomplete moisture recovery due to an excessive drying in consideration of hygroscopic property in the course of distribution. The amounts of water soluble brown pigment were two times greater in Korean dried pollack and bracken than those of Chinese products. The content of volatile basic nitrogen (VBN) were twice in Chinese dried pollack, and this may be due to foregin odor from a long transport time and distribution process. The contents of aflatoxin in Korean products were not detectable and these of Chinese products were 5 $\mu\textrm{g}$(%) in dried pollack, bracken and radish cuber. the remaining agricultural chemicals were not detectable in all products. Because of poor technique and facilities, the external appearance of Chinese products especially dried mussels and dried pollack were not uniformed in size and color. Discoloration and foregin substance such as hair, dust were checked , Korean products were mostly packed in small size in PP or bag, and Chinese products were packed in bulk size and distributed as a bulk.

  • Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

  • This study is designed to find out proper nursing activities for the needs of the colostomy patients, i.e., mental and psychological as well as physical needs for rapid recovery, and to help them build up the follow-up care for proper social adjustment. The study is based on 268 cases out of 381 colostomy patient's records kept in Ewha Womans University Hospital, Yonsei Medical Center, and National Medical Center in between the period from Jan. 1953 to Jan. 1970. The items of study are mainly on etiology, sex, age, duration of hospitalization, mortality rate, seasonal frequency, time from the onset of illness to the admission of the hospital, signs and symptoms. 1. Frequency of onset by etiology: Neoplastic disease 112 cases (42%), Inflammatory disease 33 cases (12%), Congenital malformation 30 cases (11%), Intussusception 25 cases (9.3%), Trauma 24 cases (9%), Volvulus 17 cases (6.3%), and Crohn's disease 6 cases (2.2%). 2. By sex: male 167 cases (62.9%), and female 101 cases (37.1%). So the ratio of portion of male and female 2:1. 3. By age: under 1·year·old 27 cases (10.1%) highest, 41-50 yrs 54 cases (20.2%), 51-60 yrs 42 cases (15.5%), above 71 yrs 5 cases (1.9%). 4. Duration of hospitalization: the shortest is 2-days and the longest is 470 days. 1-20-days 52%, 40-60 days 14%. 5. Mortality rate: Under the 10-days-admission 19.5%, and the beyond 30-days-admission 3.9%. 6. Seasonal frequency: Higher in summer (32% ). 7. Signs and symptoms: abdominal pain (56%), abdominal distention (54%), vomiting (40%), bloody mucoid diarrhea (38%) , pain of anal region (18%), abdominal tenderness, anorexia, indigestion, constipation, disuria, tenesmus, high fever and chilling sensation, bile tingled vomiting. Nursing activities for the patient's physical needs are as follows: Skin care for colostomy region, Prevention of colostomy constriction and depression, Removal of an offensive odor, The use of colostomy bag-selection for, and demonstration of the use of inexpensive colostomy irrigation equipment, Personal hygiene, general skin care, care of hair, finger nails and toe-nails, Oral hygiene, sleep and rest, aquate, Daily activities, etc. Measures for regulation of bowl movement. Keeping the instruction of taking food, Preparing the meal and help for anorexia, Constipation and it's solution, Prevention of diarrhea, helping the removal of mucous, and stretch constricted steam as needed. Nursing activities for pt's socio-psychological needs are as follows; Help the patient to make decision for the operation, Remove pt's anxiety toward operation and anesthesia, To meet the pt's spiritual needs at his death bed, Help to establish family and friends cooperation, Help to reduce anxiety at the time of admission and it's solution, Help to meet religious need, Help to remove pt's anxiety for loosing his job and family maintenance, Follow-up studies for 7 cases have been done to implement the present thesis. The items of the personal interviews with the patients are as follows: Acceptability for artificial anus, The most anxious thing they had in mind at the time of discharge, The most anxious thing they hat·e in mind at present, Their friends and family's attitudes toward the patient after operation, Relations with other colostomy patients, Emotional damage from the operation, Physical problem of enema, irrigation, Control of diet, Skin care, Control of offensive odor, Patient's suggestions to nurses during hospital stay and after discharge. In conclusion, the follow-up care for colostomy patients shares equal weight or perhaps more than the post-operative care. The follow-up care should include the spiritual care for moral support of the patient, to drag him out of isolation and estrangement, and make him fully participate in social activities. It is suggested that the following measures would help to rehabilitate the colostomy patients (1) mutual acquaintance with other colostomy patients if possible form a sort of club for the colostomy patient to exchange their experiences in care (2) through the team work of doctor, nurse and rehabilitation specialists, to have a sort of concerted effort for betterment of the patient.
