  • Korean Economy has been developed by the Korean Government's Support for the Large-sized Firms. This Government Policy causes the Polarization between Large-sized and Micro-sized Firms Aggravated. Micro-sized Firms are distributed over the Whole Industry Area, and can also cause the Economic Crisis If They are crashed down. Therefore Government Policy for the Micro-sized Manufacturing Industry is very Important Issue. This Paper Focused on the Analysis of Current Status for the Shoes Micro Manufacturing Industry. For the Effective Analysis, This Paper uses the Statistical Data Open to the Public and also conducts the Survey for the Micro-sized Firms in Busan. Statistical Program is used for Analyzing the Collected Data and the Major Findings are as Follows. First, Shoes Industry is led by the Micro and Small & Medium sized Firms rather than the Large-sized. And the Micro-sized Firms are getting the High Rate among the Whole Shoes Industry. Busan is heavily populated Area as the Origin of Shoes Industry. Second, even though Most of the Owner of the Micro-sized Firms have the High Technology Skill Level, Worker's Aging Phenomenon gets Worse and causes the Technology Handing down to the Next Generation Difficult. Third, Because the Factory Facility of the Micro-sized Firms is Dirt and Unstable, the Modernized Manufacturing Infrastructure such as the Apartment Factory Facility is Necessary. Forth, as the Micro-sized Firms which have the Intangible Asset such as Patent is Few, the Government Policy for Encouraging the Patent Application is strongly Needed. Fifth, Entrepreneurship and Collaboration Mind between Micro-sized Firms are Lacked, so Establishment of the Cooperative Union is required. Finally, the Effort for the Systemic Planning for the Management is lacked, and the Introduction of the Management Innovation is strongly needed. The Limitation and Future Research Direction is also discussed.

  • The sensory characteristics of red wine Gerbong (G), Campbell (C), Moru (M), Gerbong + Moru (70 : 30, GM), Gerbong + Campbell (70 : 30, GC) and French wine (F, Carbernet Sauvignon, 1998) were evaluated. The preferences of color, flavor, taste and total evaluation were determined by a ranking test, and the organoleptic characteristics were evaluated by a quantitative descriptive analysis (QDA) method. The mean color scores of C, GM, F, GC, M and G were 4.74, 3.94, 4.67, 3.70, 2.65 and 1.47, respectively (p<0.001). The order for the mean score for flavor was GM (4.12) = M (3.94) = C (3.76) = F (3.76) ${\geq}$ GC (3.12)>G (2.29) (p<0.01), and the order for taste was F (4.75) ${\geq}$ C (4.25) ${\geq}$ GM (3.37) = GC (3.50) ${\geq}$ G (2.75) = M (2.37) (p<0.001). The total evaluation of mean scores showed G, M, C, GM, GC and F were 237, 2.44, 4.06, 3.87, 3.64 and 4.81, respectively (p<0.001). Influences of sensory characteristics on the total evaluation, in percentages, were 69.3% for taste, 3.7% for color, and 1.5% for flavor. The influences of taste, color, and flavor in red wine were 17% for sweet, acid, bitter and salty taste, 28.9% for purple and red color, and 14.4% for grape flavor. The attributes of the purple and red colors showed a positive correlation with grape flavor, oak flavor, grape taste, and floral tastes, but a negative correlation with $SO_2$, flavor. The attribute of sweet taste showed a positive correlation with grape flavorand floral flavor, but a negative correlation with bitter and astringency tastes, according to Pearsons correlation analysis (p<0.01).

  • In order to improve the storage stability of powdered soybean curd, moisture sorption characteristics of the curd stored at specific relative humidity and temperature were investigated. The results obtained are summarized as follows; 1. When the fresh soybean curd (2cm thickness) was dried in a hot air drier at $55^{\circ}C$, it took 18 hrs to reduce its moisture content from 85% to 8.8%, and drying rate was very high during the first 5 hrs. 2. Equilibrum moisture content (E.M.C.) of powdered soybean curd by freeze drying was higher than that of sample by got air drying, but the particle size did not influence E. M. C. 3. The monolayer value of freeze dried powder of high E. M. C was higher than that of the hot air dried(8.30 vs 7.35). 4. The free energy for moisture absorption of freeze dried powder at 11% RH were 1285.1 cal/mole, 1323.5 cal/mole at $15^{\circ}C$ and $30^{\circ}C$, respectively, and the free energy of freeze dried product was lower that of hot air dried product. 5. The moisture sorption rate constant was not affected by particle size, and it showed that the moisture sorption rate decreased as temperature was increased. The rate constant of powder produced by freeze drying were 0.00804 at $15^{\circ}C$ and 0.00696 at $30^{\circ}C$.

  • Samples of refined soybean oil were irradiated with lights from a 20-watt incandescent tungsten lamp, a 20-watt fluorescent daylight type lamp, a 20-watt low-pressure mercury vapor germicidal lamp, and direct sunlight for an experimental period of 147 days. Some samples were stored in a dark room throughout the period as a control. The peroxide values of all samples were measured every week. The induction period of the samples was arbitrarily taken as the time required for the samples to reach a peroxide value of 15. The induction period of the control was estimated at 198 days. Those of the samples irradiated with the incandescent light, the fluorescent light, the ultraviolet light, and the sunlight were estimated at 196, 119, 52 and 6 days, respectively. The sunlight showed by far the strongest prooxidant activity whereas the incandescent light showed the weakest but distinct prooxidant activity. The small temperature differences observed among the various samples throughout the experimental period did not seem to affect the oxidation rates of the irradiated samples in any significant way.

  • Commercial edible soybean oil was introduced into plastic containers. Colorless transparent (control), red transparent, green transparent cellophane films and, also, colorless transparent cellophane films coated respectively with Cemedine C, Cemedine C containing 10% pyridine, benzophenone, and p-aminobenzoic acid were prepared, and the % transmittance of each film to lights at U.V. and visible regions were measured. The containers were covered with the films and irradiated simultaneously with direct sunlight for 4.5 hours daily. The peroxide values of the oils in the plastic containers were determined at regular intervals. The effects of the Alms on the PV development of the oils were compared with that of the control, i.e., the colorless transparent films.The red and green films showed strong retarding effects ell the PV development. The red films showed a slightly stronger effect than the green ones. The colorless transparent films coated with Cemedine C showed an appreciable retarding effect. The films had absorbed the lights at the U.V. and visible regions considerably. The pyridine and benzophenone coated films lost their retarding effects after 10 and 4 days respectively. The p- aminobenzoic acid coated films showed a considerable retarding effect throughout the experimental period. The films had absorbed the lights strongly .As a whole, the retarding effects of the films on the PV development were, in decreasing order. as follows; Red> Green> p-Aminobenzoic acid coated > Cemedine Ccoated) Control > Pyridine coated > Benz ophenone coated

  • Statement of Problem: Although many efforts have been continually made to estimate long term prognosis of removable partial dentures, the complication of removable partial dentures was still found because of inaccurate fabrication procedure and improper maintenance care. Purpose: The purpose of this study was to evaluate the clinical status of removable partial dentures. Material and methods: A total of 112 individuals with 153 removable partial dentures (35 - 87 years, 64 women and 48 men) were examined by intra-oral examination, diagnostic cast and radiographic examination. Results and conclusion: The results of this study were as follows: 1. Length of service of removable partial dentures was $5.3{\pm}4.3$ years (mean), 4.0 years (median). 2. A total of 45 removable partial dentures were considered failures. The loss of 18 abutments of 369 was founded. 3. Type of arch, Kennedy classification and type of opposite dentition were found to have no influence on longevity and success rate of removable partial dentures (P > .05). 4. Most common major connector was the palatal plate in maxilla and the number of lingual bar and linguoplate designed in mandible were similar. 5. The circumferential type retainer was the most commonly used retainer. 6. Sixty-three percent of the class I and II removable partial dentures incorporated indirect retention into the design. 7. Approximately 81% of the removable partial dentures had at least one defect. Excessive wear of posterior teeth (27.9%), lack of integrity (23.2%), lack of stability (22.6%) were frequent defects of removable partial dentures.

  • Background : A pleural effusion is a common medical problem. Despite several diagnostic tests, 15-20% of pleural effusions go undiagnosed. The aim of this study was to evaluate the clinical characteristics and prognosis of a lymphocyte dominant exudative pleural effusion with a low adenosine deaminase (ADA), low carcinoembryonic antigen (CEA), negative cytology and negative acid fast bacilli (AFB) smear. Method : From Jan 2000 to Aug 2001, 43 patients with lymphocyte dominant exudative pleural effusions whose AFB smear and cytologic exam were negative, their pleural fluid ADA level was < 40 IU/L, and their CEA level was < 10 ng/mL were enrolled in this study. A retrospective analysis of the patients' medical records was carried out. Result : Among 31 of the 43 cases (72%), probable underlying diseases causing the pleural effusion were identified: 21cases of malignant diseases, 4 cases of liver cirrhosis, 2 cases of pulmonary tuberculosis, 1 case of end stage renal disease, 1 case of a chylothorax, 1 case of a post-CABG (coronary artery bypass graft) state, 1 case of a pulmonary embolism. No clinically suspected etiology was identified in the remaining 12 cases (28%). Of these 12 pleural effusions, 7 cases spontaneously resolved, 2 effusions resolved with antibiotics, and the other 2 cases were persistent. Conclusion : Lymphocyte dominant exudative pleural effusions with a low ADA, low CEA, negative cytological exam, and negative AFB smear, but without a definite cause might have a benign course and clinicians can observe them with attention.

  • Background: As the number of older-aged people increases, the number of elderly patients who receive critical care services is expected to increase substantially. The objective of this study was to examine the clinical characteristics and outcomes of elderly patients who receive mechanical ventilation for more than 30 days in the medical intensive care unit (MICU) at a university hospital. Methods: We retrospectively examined forty-one elderly patients (${\geq}65$ years old) who were receiving mechanical ventilation, from April 2004 to March 2007, for periods exceeding 30 days at the MICU at Eulji University Hospital. Results: The MICU and hospitalmortality rate were 60.9% and 65.9%, respectively. The mean length of the ICU stay was 57.5 days and the mean duration of mechanical ventilation was 49.3 days. The most common reason for MICU admission was acute respiratory failure (73.2%), followed by sepsis (12.2%), neurological problems (9.8%), and gastrointestinal bleeding (4.9%). The Acute Physiology and Chronic Health Evaluation (APACHE) II scores were higher for the nonsurvivors than for the survivors (28.0 vs. 25.0, respectively, p=0.03). The nonsurvivors received more red blood cell (RBC) transfusions during their ICU stay than did the survivors (84.0% vs. 43.8%, respectively p=0.007). The factors associated with hospital death were the APACHE II score and if the patient had received a RBC transfusion. Conclusion: The APACHE II score and a RBC transfusion were predictors of increased hospital mortality for the elderly patients who were on prolonged mechanical ventilation. These predictors may assist physicians to make clinical decisions for this patient population.

  • This study was carried out to investigate the effects of ultrasonic thawing on physicochemical characteristics of frozen pork sirloin. To determine the velocity of an ultrasonic thawing machine, $-80^{\circ}C$ frozen pork sirloins were thawed using 132, 580, and 1,000 kHz ultrasonic thawing machines, and the physicochemical properties of pork sirloin thawed with $15^{\circ}C$ tap water and those using the ultrasonic thawing machines were compared. As a result, thawing speed by ultrasonic thawing was three times faster than that of tap water, but drip weight loss rate is increased by about 5% during ultrasonic thawing compared to that during thawing in tap water. However, biochemical properties, such as pH, volatile basic nitrogen, thiobarbituric acid, and total aerobic bacteria, were not improved by ultrasonic thawing. Hunter values, such as total color change and redness, improved slightly after 580 kHz ultrasonic thawing. The hardness and chewiness of the pork sirloin decreased significantly after 580 kHz ultrasonic thawing; however, springiness was not changed. These results indicate that ultrasonic thawing is faster than thawing in tap water, but the physicochemical characteristics of frozen pork sirloin was not significantly improve by ultrasonic sound.
