For the development of kiwifruit storage method applicable to farm level, several quality indicator of kiwifruit(Actinidia chinensis Planch.) were measured during storage at modified atmosphere(MA) conditions(0.04, 0.06, 0.08 and 0.10 mm PE Film). The results obtained from the experiment were as follows. The highest firmness was marked by the kiwifruit kept in 0.06 mm thick film bag and the lowest weight loss was shown in 0.10 mm thick film bag. The largest production of respiratory rate was occured after storage for 30 days. The concentration of $O_2\;and\;CO_2$ in 0.06 mm thick film bag was 2.6% and 3.2% after storage for 60 days, respectively. It could be concluded that the optimum PE film thickness for MA storage of kiwifruit was 0.06 mm.

Ebstein's anomaly is an unusual and a rare congenital cardiac malformation but characteristic abnormality of the development of the tricuspid valve, right atrium and ventricle. The characteristic findings are a displaced tricuspid valve with a septal leaflet spiralling into the right ventricle. The surgical correction is variable and are left unsolved problem in surgical treatment of anomaly. Between January 1988 ＆ December 1995, we experienced 11 cases of Ebstein's anomaly and associated cardiac anomalies are ASD, PFO, ASD with VSD. The typically displaced tricuspid valve leaflet was found in all cases. In the NYHA functional classification, three were in class II, seven were in class III, and one was in class IV. Nine patients were operated by tricuspid annuloplasty ＆ plication with Danielson's method and two patients were done by tricuspid valve replacement with plication, and in all cases associated anomaly was corrected. Postoperatively, five patients suffered from complication - low cardiac output syndrome, arrhythmia and wound infection. There was no operative mortality and the postoperative courses were relatively good conditions with more improvement of symptoms.

This study was conducted to evaluate health consequences of phenol resin workers for 6 weeks from February 21, to March 28, 1986. The subject population was 26 in a factory with phenol resin and control group was 30 non-exposed workers who were working in the other factory. The biological parameters chosen for this study were phenol concentration in working room-air, total phenol level in urine and BUN of phenol resin workers. The phenol concentration in working room-air and total phenol in urine were significantly correlated (r=0.791, p<0.01). The frequency of symptom and sign in phenol resin workers were higher than control group. The frequent symptom and sign were coughing, weight loss, poor appetite, headache, dyspnea, eye irritation and tinnitus, in order. Total phenol in urine was not reversed to normal range in spite of interruption of exposure for 4 days. The BUN value in blood and total phenol in urine were not correlated.

This study was conducted to verify the effects of preparatory information, the anxiety level of premedication as well as physiologic variable of patients undergoing bronchoscopy. Data collection was performed from June 4 from December 28 2007 with 102 patients. The degree of anxiety of the subjects was measured by the Spielberger State Trait Anxiety Inventory (Korea version). A booklet constructed by researcher as a research tool was used or patients education. Data were analyzed by using SPSS 14.0 program. As a result of the effect that preparatory information and premedication to the subjects undergoing bronchoscopy was statistically effective in reducing the degree of anxiety(p=.005) and controlling pulse rate(p=.033), respiratory rate(p=.006) on the specific threatening procedure but show no significant effectiveness on stabilizing systolic pressure(p=.062) and diastolic pressure(p=.189). Therefore it is thought that it can be actively applied to clinical practice.

This study was aimed to identify surgical ward nurses' importance-performance awareness toward early mobilization after abdominal surgery patients. The date were collected from 162 nurses and the importance and performance of early mobilization were analyzed by the IPA method. The collected data were analyzed using the SPSS/WIN 25.0 by implementing descriptive statistics, independent t-test, paired t-test, and ANOVA. Early mobilization was divided into exercise of pulmonary complications and early ambulation. As a result of the study, the areas requiring concentration were 'check risk of aspiration', and areas requiring improvement were 'oral care', 'check lung sound', 'percussion/vibration', 'suction', and 'reinforcement exercise in bed'. Therefore, each item of early mobilization is recommended to reduce the gap between importance and performance in clinical care.

Background : Tuberculous pleurisy has been treated With a combined regimen of corticosteroids- antimicrobial therapy. But whether such combination therapy add to benefits is unknown. We evaluate the effects of corticosteroid and its routine application in relief of clinical symptoms, absorption of pleural effusion, and pleural adhesions. Methods : A prospective, randomized study of the role of corticosteroid in the treatment of tuberculous pleurisy was performed in 83 patients(nonsteroid group: 50 patients, steroid group: 33 patients) from June, 1991 to September, 1994. Results : 1) The mean duration from symptoms(fever, chest pain, dyspnea) to relief was 3.8 days in the steroid group, and 7.4 days in the nonsteroid group(P<0.05). Clinical symptoms including fever, chest pain, sputum and weight loss were relieved more rapidly in the steroid group than other symptoms(weakness, night sweating and dyspnea). 2) Pleural effusion was taken an averge of 88 days in the steroid group and 101 days in the nonsteroid group 10 be absorbed completely(p>0.05) 3) The incidence of pleural adhesions was 17/33(5l.5%) in the steroid group and 32/50(64%) in the nonsteroid group(p>0.05) 4) Side effects of corticosteroids were observed in only one patient causing epigastric pain and discontinuation of drug. Conclusion : Corticosteroid exert benefitial role in the more rapid relief of clinical symptoms to patients with tuberculous pleurisy, but absortion of pleural effusion and occurrence of pleural adhesions was not influenced significantly Therefore, its routine application should be reevaluated.

Background: After general anesthesia, decrease of functional residual capacity and lung compliance, ventilation/perfusion imbalance, and transpulmonary shunting can provoke hypoxemia during postoperative periods. Diaphragmatic dysfunction may be the main cause of these physiological abnormalities. Thus, we evaluated the change of pulmonary function after general anesthesia according to the operative sites, which could suggest clinical course and critical period of respiratory care of postoperative patients. Method: Preoperative portable spirometric evaluation and arterial blood gas analysis were performed at sitting or most-sitting position just previous day of surgery. Pulmonary function tests were also as same condition from postoperative day 1 to day 5. Results: 1) For thoracic surgery, FEV1 and FVC were not recovered at day 5, but FEV1/FVC was not decreased. $PaCO_2$ was slightly elevated at postoperative one day. 2) After upper abdominal surgery, postoperative day 5 did not show the recovery of FEV1 and FVC, but mild hypoxemia was developed at postoperative day 1. 3) Pulmonary function was recovered as preoperative value at postoperative day 5 in lower abdominal operation, but mild hypoxemia was also noted at postoperative day 1. 4) Surgery of peripheral areas did not show significant pulmonary function change and hypoxemia and hypercapnia from postoperative day 1. Conclusion: Surgery involving diaphragm provoke significant postoperative pulmonary function change after day 5. For the operation of peripheral sites adequate respiratory care during operation and postoperative period within 24 hours could prevent patients from respiratory complication.

Purpose: The prevalence of lung cancer is increasing continuously these days. We studied clinical characters of the terminal lung cancer patients who had died in hospice units and our study is the basic report for efficient hospice and palliative care to the lung cancer patients. Methods: We retrospectively reviewed the medical records of 129 terminal lung cancer patients who had died in Sam Anyang Hospice Unit from March 2003 to December 2006. The survival days during the hospice and palliative care were analyzed using Kaplan-Meier method of SPSS 13.0. Results: There were 93 males (72%) and 36 females (28%), and median age of patients was 68 years (range $37{\sim}93$). Eighty two patients (64%) took analgesics, the others 47 (36%) not. The most prevalent reason for admission was dyspnea (47 patients, 36%) and it was different from the terminally ill cancer patients being hospitalized because of pain. And the most common symptom was general weakness (103 patients, 80%). One hundred twenty of the paitents (93%) were administered opioid analgesics, and IV morphine shots were mostly used (103 patients, 80%). Sedation was used in 87 patients (67%), and midazolam was mostly used (68 patients, 53%). The median survival in hospice and palliative care was 35 days and the median hospitalization was 24 days. Conclusion: It is very important to manage dyspnea in terminal lung cancer patients. The length of hospice and palliative care for the terminal lung cancer patients is still short. Therefore continuous education and promotion of hospice and palliative care is needed for an effective care for the patients, their families and doctors.
