We investigated the frames represented in the news media coverage in Korean daily newspapers during dismissal procedure of the director-general of the public service broadcaster, KBS. We analyzed 470 newspaper stories in the period surrounding the dismissal. The use of news frames in newspapers depended on the disposition of outlets, conservative or progressive. Conservative newspapers, ChoSun and DongA, described the dismissal of the director -general with a generally favorable or supportive view, but progressive outlets, Hankyoreh and KyeongHyang, reported more and non-favorable for the issue. Our results showed that conservative newspapers more often used episodic and cause for dismissal frame in the presentation of news, whereas progressive more often used thematic and media independence frames. Main frames commonly used in the news are the cause for dismissal, conflict, media independence, and regime maintenance, respectively, which are formed by 9 minor news frames. Conservative newspapers concentered on the cause attribution; management responsibility, conflicts, and dismissal procedures, but progressive focused on media independence and dismissal procedures. All newspapers selectively quoted groups, institutions and actors to enhance their messages and frames. Finally, there was significant difference between stories in each newspapers and the court's ruling for the dismissal.

The Sarisan clay deposits of hydrothermal origin are found in the intensely weathered wto-mica granite in Yeoju area. The major clay minerals of the Sarisan mine are illite and montmorillonite with minor disordered kaolinite, vermiculite, and some interstratified mineral. Clay minerals were studied using various methods including X-ray diffraction, infrared absorption spectroscopy, electron microscopy, and thermal and chemical analyses. Illites occur as discrete illite or highly illitic interstratified mineral. They are of 1M and $2M_1$ polytypes and characterized by a low lattice charge (1.768-0.926 per unit formula), low $K^+$ content (0.741-0.902 per unit formula), and high Si/Al ratio (1.154-1.293) as compared with muscovite. Montmorillonites are highly negative charged and occasionally random-interstratified as I/S with 80-98% smectite. Hydrothermal alteration is more important than later weathering alteration for the formation of illite and montmorillonite clay minerals. The hydrothermal alteration took place through two stages; the formation of illite in the early stage and the formation of montmorillonite in the late stage. Disordered kaolinite and vermiculite are the weathering products of plagioclase and biotite, respectively.

The Earth outer core accomodates moderately considerable amount of lighter elements than pure iron itself. Hydrogen is one of the possible candidates of minor constituents in the outer core. It would be worth while to extend for the pressure effect on the solubility of hydrogen in the metal-hydrides including iron hydride. In view of hydrogen being one of the potential substitutes for petroleum, searching a more efficient way for storing hydrogen in the form of hydrides is of considerable value. For two purposes, $TiH_2$was selected among lot of hydrides for its characteristics under pressure and temperature. There have been two kinds of experiment carried out on $TiH_2$ under different experimental conditions. As one of these attempts, polycrystalline $TiH_2$ was loaded up to 15 GPa stepwise at the constant temperature 500${\circ}$ using a piston-cylinder diamond anvil cell equipped with a miniature furnace of an electric power supply. The X-ra diffraction technique was employed on the quenched samples after the simultaneous high pressure and temperature treatments. During these high pressure-temperature runs, and irreversible phase of $TiH_2$ has been observed at the pressures higher than 11.3 GPa, which would be assigned to the orthorhombic crystal system as one of the new phase(s) of $TiH_2$. Molar volume change on this phase transition is ∼10%.

Objective : The anterior communicating artery(ACoA) is known to be the most frequent location of intracranial aneurysms, but the complex arterial anatomy of the ACoA region makes this aneurysm among the most difficult one to treat. In the treatment of ACoA aneurysms, the direction of aneurysmal fundus is known to be very important in the surgical tactics. All ACoA aneurysms in our series were classified according to its direction, and analyzed the clinical features in order to investigate the prognostic factors influencing upon the surgical outcome. Methods : The authors reviewed 236 cases of ruptured ACoA aneurysms that were operated from 1990 to 1997, were classified according to Pia's classification. Results : The incidence rate of the ACoA aneurysm was 35.1%(236/672). Ventral group was more common than dorsal group, especially in ventro-caudal projection subgroup(36.0%). Poor preoperative clinical grade(Hunt-Hess grade IV and V) patients were more common in dorsal group(13.1%) than ventral group(2.6%). Rebleeding and intracerebral hematoma were more commonly seen in ventral group. However, vasospasm, hydrocephalus, hyponatremia, and intraventricular hemorrhage were observed more frequently in dorsal group. Worse outcome was more common in dorsal group than ventral group, especially in dorso-caudal projection subgroup. Also, poor outcome was identified in patients with intracerebral hematoma, intraventricular hemorrhage, hyponatremia, and hypertension, although statistically insignificant. In cases with the A1 dominancy, there was no difference in surgical outcome between the right and left side approach. The higher the aneurysmal neck from the planum sphenoidale, the worse outcome via pterional approach. Conclusion : It seems that the preoperative clinical grade, aneurysmal direction, and the height of aneurysmal neck, especially in the pterional approach, would be the major prognostic factors, and that intracerebral hematoma, intraventricular hemorrhage, hyponatremia, hydrocephalus and the intraoperative aneurysmal rupture would be the minor prognostic factors.

Metabolic syndrome is a cluster of metabolic risk factors associated with increased risk of cardiovascular diseases. Recently, the prevalence of metabolic syndrome has increased in Korea. The aim of this study was to develop a Healthy Han-sik Nutrition Education Program (HHNEP) based on commonly recognized Korean foods in order to decrease metabolic syndrome risks. The target population of the HHNEP is adults with metabolic risk factors. The initial version of the HHNEP was developed based on a review of literature and various dietary guidelines by expert committees as well as the results of a survey on the perception of common Korean dishes and foods as Han-sik. The focus group discussion conducted of nine participants from the target population. After minor modification, the final version was developed. The contents included five sections: 1) aims, 2) introduction of Korean Food Guidance System, 3) cholesterol contents in food, 4) menu planning method using Han-sik, and 5) examples of daily Han-sik menu. The Han-sik list was selected based on the results from a Han-sik perception answered by 35 Korean adults aged 30-60 years using 517 frequently consumed Korean foods from the fourth Korea National Health and Nutrition Examination Survey. The nutrition education program was developed based on scientific evidence for the prevention of metabolic syndrome and focuses on tailoring education to an individual's dietary problems. Educational method was developed by a group of expert committees based in planned behavior theory and related research results. The education method consisted of assessment of current diet, four face-to-face nutrition education sessions over 8 weeks, and evaluation after 8 and 16 weeks. Initial version of nutrition education materials and methods was tested for feasibility by a select group of nine Korean healthy adults. Successful implementation of the program would include application by nutritional professionals at the health promotion center of the hospitals, public health center, and work sites. Intervention studies are needed to evaluate the feasibility and effectiveness of this program before large-scale applications.

Persimmon occupied the second largest cultivation area next to apple among the fruits in Korea. Since 70 % of its cultivating field is located at slope, the efficiency of its harvesting operation is very low. Also, the traditional persimmon harvest apparatus does not seem to be efficient to use due to a structural problem. In this paper, the author has analyzed the physical properties of persimmon friut-stem system and compared detachment force with developed persimmon harvest apparatus and traditional persimmon harvest apparatus in order to solve the problems mentioned above. The results of the research are summarized as follows : 1. The weight of the persimmon is shown as 157 g on average, the lengths of stem's major axis and minor axis is shown as 4.6 mm and 3.7 mm on average, respectively, sectional area of stem is shown as $13.9mm^2$ on average and the stem length is shown as 13.6 mm on average. 2 In case of the traditional persimmon harvest apparatus, the detachment force needed when a persimmon was detached from its stem was shown as 86.3 N on average. 3. In case of the developed persimmon harvest apparatus, detachment force needed when a persimmon was detached from its stem was shown as 72.6 N on average.

The visually impaired who have many restrictions on their sight due to impairment of a sense of sight among special senses have substantial difficulties in the areas ranging from very minor behavior in their house to the external activities for social life. Visual impairment may cause many problems in various behaviors for protecting health which have recently drawn a lot of interests. As a method of analysis of collected data, this study conducted the frequency analysis of general characteristics and oral health behavior of the subjects, compared the average of oral public health behavior and oral health condition through t-test and F-test, and conducted the post verification of significant difference among groups with Duncan. For identifying the relevancy between the general characteristics and the oral health behavior, this study conducted Spearman's correlation analysis, and for identifying the impact on subjective, oral health condition, this study conducted multiple regression analysis. SPSS (SPSS20.0 for Windows, SPSS Inc, USA) was used as a statistical program, and the level of significance for determining statistical significance was considered at the level of 0.05. Because the visually impaired are the group whose behaviors for protecting health should be accurately recognized, this study intends to utilize the findings as basic materials for making information communication media suitable for the visually impaired by identifying the real conditions and behaviors of their oral health and analyzing their oral condition caused by such behaviors. With the help of information technology.

The objective of this study was to evaluate the effects of different levels of red ginseng mare or Korean mistletoe powder on growth performance and physicochemical properties of thigh meat in broiler. A total of 200 broiler chicks were divided into five groups were fed a basal diet (control), basal diet supplemented with 0.5% red ginseng mare (T1), red ginseng mare 1% added (T2), Korean mistletoe 0.5% added (T3), Korean mistletoe 0.5% added (T4) for five weeks. Growth performance and proximate composition of chicken thigh meat were not influenced by all treatments, except for mortality and crude fat, which was significantly lower in all treatments with red ginseng mare or Korean mistletoe powder compared to control. Dietary red ginseng mare and Korean mistletoe supplementation had no significantly effects on pH, WHC, shear force, CIE $L^*$, $b^*$ values, triglyceride and glucose but TBARS values total cholesterol, and LDL-cholesterol were decreased (P<0.05) by the addition red ginseng mare and Korean mistletoe powder. CIE $a^*$ values increased significantly with added red ginseng mare and Korean mistletoe powder relative to the control (P<0.05). It was concluded that the addition of red ginseng mare and Korean mistletoe powder revealed minor improvements in the lipid oxidative stability of chicken meat.

The criminal procedure is based upon two ideal values, or 'speedy trial and economy of litigation' and 'finding truth and guarantee of human rights', which are conflicting each other. The so called summary trial system, a simplified procedure through which a judge handles clearly obvious and minor offences in a quick and efficient manner, has its essential purpose of termination lawsuits promptly and freeing suspects or defendants from criminal procedure at the earliest possible moment. But its excessive emphasis on this purport is very likely to result in insufficient examination and inadequate protection of suspects' or defendants' rights. Therefore, the summary trial system needs a variety of safeguards to prevent these feasible - but undesirable - effects. From this point of view, we should objectively review the current summary trial system. The main object of this study is to investigate what problems the system has both in institution and in practice, and to suggest legal measures, including the abolition of it, to improve the simplified procedure. In conclusion, the summary trial system should be maintained because it has still more merits than faults. And these defects will be able to be overcome by reform measures ; for example, the introduction of the right to opt between the summary procedure and the formal trial, the abolition of detention and so on.

Bronchial adenoma, firstly described by Muller[1882] had been reported on the subject stressed their benign nature prior to 1940`s, but these tumors including carcinoid tumor, mucoepidermoid carcinoma, adenoid cystic carcinoma, pleomorphic adenoma are now known to possess the various degree of malignant natures from benign course, low grade malignant potential to distant lymphatic or hematogenous metastasis or combination. Although histologically diffeerent, four varieties except carcinoid tumor which is a spectrum of neu-roendocrine tumor originating Kulchitsky cell of the bronchial epithelium and form the part of the APUD tumor spectrum, are morphologically and in many respects clinically similar to the corresponding tumor of the salivary gland is a specific varient of adenocarcinoma that occurs most commonly in the major and minor salivary gland and less frequently tra-cheobronchial tree, esophagus etc. To better understand the clinical characteristics and assess more precisely the malignat nature of bronchial adenoma, we studied 17 cases of bronchial adenoma, which had been experienced at the Department of Thoracic and Cardiovascular surgery of Catholic University Medical College from April 1977 to september 1991. Seventeen cases of bronchial adenoma consist of 2 carcinoid tumors, 6 adenoid cystic carcinomas, 8 mucoepidermoid carcinomas and one pleomorphic adenoma. There is a slight predominace of male patients[10/17] and the age of pt studied varied with a higher incidence occurring between the ages of 40 years and 60 years[mean age, 46.5 years]; the youngest being 15 years and oldest 69 years. Their leading complaints were hemoptysis[4], exertional dyspnea[8], fever & chilness [4], and symptoms mimicking the bronchial asthma[4]. Diagnosis was aided by the radiologic studies such as chest X-ray, polytomography, CT scan, brochography and bronchoscopy. The preferred locations of fumor were in the trachea[4], main stem bronchus[3], bronchus intermedius[3], bronchus of RUL[2], LUL[1], RLL[1], LLL[3] with no peripheral location. Modalities of treatments were single or combination of surgical resection, radiation therapy, chemotherapy. Complete resections were permitted in 12 cases with late recurrences of 4 cases ranging from 6 months to 10 years: pneumonectomy[4], lobectomy[4], bil-obectomy[2], sleeve resection[2]. Gross findings of resected specimens in 14 cases showed that 4 cases were polyp-like pedunculated mass[entirely intraluminal mass] with intact mucosa, 8 cases were broad-bas-ed sessile mass[predominatly intraluminal] and the main portions were located below the mucosa similar to tip of iceburg[predominantly extraluminal] in 2 cases. Follow-up information was availble in all 17 cases ; eight were alive without evidence of disese ranging from 1 month to 13 years. But seven cases died of the causes related to tumor[6 cases within 12 months, one case 10 years after pneumonectomy]. We concluded that 8 cases[47%] of 17 cases were metastasizing bronchial adenoma and precise survival rate cannot be answered by the scanty materials available for study.
