Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

In content-base video data retrieval, the detection for scene change is needed. Color histogram approaches are generally used. Color histogram approaches are simple and more robust to object and camera movements but they ignore the spatial information and fail when two different frames have similar histograms. We propose a new algorithm to use color histogram and entropy to enhance the false-positive occurred by brightness variation and the miss by similar color histogram. At the experiments, it is more robust to brightness variation and have spatial information.

The author had analyzed respectively a series of 58 patients with severe head injury observed for 6 months from January 1995 to June 1995 to evaluate the significance of the factors of the factors affecting outcome. Severe head injury was defined as a Glasgow coma scale(GCS) score of 8 or less after acute non-surgical resuscitation, or deterioration to that level with 48 hours of impact. Our analysis was performed according to the patients age, initial GCS, pupil change, motor response, CT findings, systolic BP & arterial 02 level. The results were summerized as follows. 1. The most common cause of severe head injury was traffic accidents. 2. The 33(62%) out of 58 patients were found between third decade and sixth decade. 3. The initial GCS had does relationship with pupil change and motor response(P<0.001). Also hypoxia and hypotension affected the initial GCS but then was not significant statistical difference to out-come(P>0.1). The pupil change and the motor response were very strongly associated with the initial GCS (P<0.001). Also early hypotension (systolic pressure<90mmHg) and early hypoxia (Pa02<60mmHg) had a close correlation with initial GCS, but there was not significant statistical difference to out-come(P>0.1). 4. The factors affecting prognostic difference were initial GCS, pupillary abnormality, abnormal motor response, hypotension and hypoxia.

This report is a retrospective clinical study of 60 patients with abdominal trauma admitted and treated at the department of emergency medicine of DanKuk University hospital during the period from January 1995 to December 1995. we obtained following results. 1) The sex distribution was 45 males(75%) and 15(25%) females with significant predominence in male(3:1), and the age distribution revealed high incidence in second to fourth decades(50%). 2) The cases of the abdominal trauma were traffic accident(80%) in most common, violence, fall down in order frequency. All were blunt trauma. 3) The clinical manifestations and physical examination were abdominal pain(92%), abdominal tenderness, rigidity, decreased bowel sound, rebound tenderness in order frequency. 4) The shock status on admission(below 80 mmHg in systolic) were 10 cases with high mortality(30%). 5) The hematocrit changes in serial check after admission were 36 cases(60%). 6) The diagnostic methods were abdominal paracentesis, simple X-ray, abdominal sonography, abdominal CT, and DPL(Diagnostic Peritoneal Lavage). The abdominal paracentesis showed positive 36 cases(63%) among 48 cases. Abdominal paracentesis was one of the valuable diagnostic method in abdominal trauma. The Abdominal CT was the best diagnostic method in solitary organ injury, but the diagnostic rate was very low(25%) in small bowel injury. 7) The injured intraabdominal organs were small bowel(41%), liver(30%), spleen(20%), and kidney(17%). 8) The commonly associated extraabdominal injury were chest trauma(30%), upper and lower extremity injuries(20%), head trauma(15%). 9) The overall mortality rate was 5%, in abdominal trauma with multiple injury.

Design is a result from representation of visual language by designer's creative thinking and reasoning, and operated only in our internal organization system. Design as ill-defined problem cannot be described logically and perfectly. Depend on situation, design require subjective analysis. and It has the organization of What is Rank character. But because "Concept" is only considered in the designer's thinking system, shape vocabularies that actually can be used for expressions of design are extremely restricted. Sometimes design should start with changing situations, unclear requirements, subjective analysis. But design concept can control design thinking system from starts to productions. Design concepts are stored in our brains and retrieved as three major types such as elements, relationships and schema. One of these words, the schema that formed by problems settlement and process repetitions for the best conclusion, not only play an important part in the designer's thinking system about a specific problem but also appeared by distinctive features and included by connotations as like a designer's ideology. At this point. The purpose of this study is that analyze not only the formative expression but also modeling process of design elements in modern architectural design to establish a clear-system of "Design Operating System" and to show the "Characteristic of Plane Organization" by the he Architectural Design Elements and the Relationship through the Design of Louis I. Kahn. and Design knowledge as elements, relationships and schema have been explained to understand "Design System" operated in our brains. Upon these studies, design of Louis, I. Kahn have been analysed.

At present Korea faces a radical turning point for its economy. The government and the companies are experiencing difficult time making export strategies after the UR agreement. I think that the companies should be prepared for the international competition by positively coping with the rapid change as well as managing the human resources efficiently in order to overcome this situation. Under the circumstances, the managers of a company should develop and employ some ways of heightening their workers' morale and keeping their high morale in the course of working to improve the performance of an organization or the productivity. The main purpose of this study is to find out the factors influencing the workers' morale and examine the interrelationship of the factors of measurement, influence and intermediation. I made an empirical and theoretical approach to achieve this purpose. At first, I made a theoretical basis by reviewing several preceding studies. Then, after establishing study hypotheses and models on the basis of the theoretical study, I analyzed this study empirically, dealing with the subjects of hotel workers in Cheju area on the basis of the questionnaires. I chose the three areas of the relations of morale, the factor of morale measurement, and morale and influence for study models. I also employed a correlation, oneway ANOVA, and a T-test for the statistics. I analyzed the study data using SPSS/PC'. From this study I found several consequences about managing human resources: (1) It is necessary to take a measure for the employrees' high morale because morale has turned out to have a positive effect on job performance, job satisfaction, and job involvement. (2) In relationships between morale, propensity to seperation, and tardiness and absence, there was no conspicuous negative tendeccy, Regarding this, it is suggested that there be a proper management plan regarding the transfer of and departure from jobs preventing workers from being absent from and being late for workplace. (3) It is necessary to focus on creating high morale for high solidarity and loyality. (4) The management should encourage their employees to have a positive attitude towards their work by reducing tension, uneasiness, and complaints. (5) Something should be done for job design to assign the jobs fit for workers' aptitudes. (6) Something unique for a hotel organization should be done to bridge the morale gap, depending on demographic factors.

Severe head injury is associated with a stress response that includes hyperglycemia, which has been shown to worse outcome during cerebral ischemia. To better define the relationship between head injury and hyperglycemia, admission glucose level were analyzed in 150 head injured patients from January 1995 to December 1995. Our retrospective study demonstrated a higher glucose level in patients with low Glasgow Coma Scale(GCS) score, especially at 3-5 GCS score, compared to those with high GCS scores. Also a higher glucose level was noted in patients with vegetative state and dead than in those with good recovery and moderate disability. Hyperglycemia(serum glucose level≥200mg%) was associated with decreased level of consciousness and a poor outcome. We conclude that admission hyperglycemia is a significant indicator of severity of injury(p<0.001), but not significant predictor outcome from head injury. After controlling for the influence of the GCS score, glucose levels do not have an independent effect on outcome.
