  • Kyungokgos purchased in local markets in Korea vary in their combination and mixing ratios during processing. This study was investigated qualities of Kyungokgos manufactured traditionally to evaluating its qualities. The general components of Kyungokgos were moisture (18.62~49.78%), ash (0.198~1.211%), protein (0.89~3.58%), lipid (0.16~1.14%) and carbohydrates (47.95~77.08%). The color values of L, a, and b were 26.49~73.87, 16.51~38.64, and 45.41~88.94, respectively. The viscosity was classified into three non-Newtonian type groups: high, medium, and non-dilatant, according to the increase of loop execution times. Three extracts (KOG-1, -7, and -8, in a 30-fold dilution) showed no cytotoxicity toward RAW 264.7 cells, while the extracts of KOG-2, -4, and -5 showed a low cytotoxic effect. KOG-1 and -2 extracts with low cytotoxicity markedly inhibited the production of the inflammatory mediators-nitric oxide (NO) and tumor necrosis factor-alpha (TNF-${\alpha}$) in LPS-stimulated RAW 264.7 cells. These results indicate that KOG-1 and -2 extracts have anti-inflammatory activity in LPS-stimulated RAW 264.7 macrophages.

  • A total of 33 accessions of pepper (Capsicum spp.), including previously reported and newly discovered sources of resistance to bacterial spot caused by Xanthomonas euvesicatoria, were evaluated for their resistance to bacterial spot. The selected accessions were then grown and their horticultural characteristics were recorded. In a test for hypersensitive resistance (HR) to four races (P1, P3, P7, P8) of the pathogen found in Korea, KC00939 and Chilbok No.2, which carry the Bs2 gene, exhibited a hypersensitive response to all four races, as expected. Chilbok No.3, which carries the Bs3 gene, showed a hypersensitive reaction to race 1 and 7, as expected. KC00939 exhibited a high ASTA color value and tolerance to multiple infections from a viral complex of Cucumber mosaic virus (CMV) and Broad bean wilt virus (BBWV). Thus, this accession represents a promising genetic resource for breeding cultivars with multiple disease resistance and strong red coloration. KC01327, KC01617, KC01015, KC01760, KC01779, KC01137, KC01328, KC01006, KC00127, KC01704, and KC00995 did not exhibit hypersensitivity but showed a high level of general resistance when evaluated by spray inoculation. KC01617, KC01760, KC01779, KC01137, KC01704, and KC01777 are newly identified sources of resistance to bacterial spot. The previously and newly identified sources of resistance to bacterial spot evaluated in this study, including information about their resistance to CMV and BBWV complex in the field, the contents of pungent and sweet taste components, and the color values of dry fruits, will be useful for breeding pepper cultivars with resistance to bacterial spot.

  • This study was projected to get basic data which can provide a basis for future direction in nutritional education, and also to find the way how to improve the nutritional supply by evaluating the current nutritional intake of average high school students through the survey study of their daily packed lunch. Five hundred twenty seven students from two boys high school and two girls high school including one general and one vocational school respectively were chosen as random sampling technique. Four hundred forty nine among the 527 students had brought lunch. The contents of lunch box were weighed and converted into nutritional values according to the food composition table and compared with recommended dietary allowances. The results compared and classified by sex, School and housewives' educational level were as follows: 1. The nutritional supply in the lunch box was 671 Cal of energy and 22.3 gm of protein for male students which were respectively 55.9% and 74.2% of the dietary recommendations. On the other side female student's lunch boxes were found to contain 495 Cal of energy and 21.3gm of protein which are respectively 61.8% and 80% of the dietary prescriptions. Excluding niacin, all vitamins and minerals were found to be short. 2. Calorie intake in the vocational high school was found to be higher than in the general high school but lower in protein intake especially significant difference (P<0.01) in animal protein. 3. From the nutritional point of view the educational backgrouud of the housewives was not found to have any influence in the way of preparing the lunch boxes. 4. Nutrients of lunch box were heavily inclined to grain rather than to side dishes.

  • The nutritional status is strictly related with flood production, flood processing, and distribution along with habits, education and technological achievement, adapted and adjusted to socio-economic conditions. All these factors are independently affecting the nutritional status of populations. In addition to the above mentioned factors launch of it is useful to consider two points ; unification of the South and the North Korea and WTO. The present study gives and overview of basic knowledge about nutritional status of Korean by using availab1e data in relation to nutrition. The basic characteristics of Korean diet with proportions high in carbohydrate and low in fat, have been relatively constant for the past two decades. The average daily flood intake in terms of weight of flood per person is relatively constant throughout the years. Although the proportion of animal food intake tends to increase recently, the Korean diet is still insufficient in meat, eggs, milk, and fish. Moreover because milk has not been accustomed flood with the general population and not much used in traditional flood preparation in Korea, milk consumption was especially low in comparison with western countries. The total energy intake was relatively constant throughout the years from 1969 to 1993. However, changes in the composition have occurred in the past two decades. The amount and proportions of fat have been s1ightly increasing while the total amount of carbohydrate has been decreasing. The nutrition preblems of Korea have changed over the past severa1 decades. The general adequacy of protein and energy existing after Korean War(1950) was resolved now. Since then the average diet appears to be nearly desirable in terms of rapid rates of growth during childhood and attainment of progressively stature and body weight at maturity. The dietary habits of some young people in these days seem to be taking a more western style diets. This trends if established by habit may lead to a marked change in the traditional diet and health. I think Korean nutritional experiences have potential values for tole other countries in Asia and in western countries. Korean diet illustrates a high level of nutritional status and health attainable will a largely vegetable diet : high in complex carbohydrates, and dietary fibre, and low in tat, and reasonable amount of total protein. This is significant for developing and developed countries that must select specific goals fir adequate nutrition for the people. Compared to the western countries, Koreas different incidence of coronary heart disease and malignancy demonstrates the significance of environment and probably the prominent role of diet in the development of these diseases. The changes occurring in the Korean diet of fir the unusual opportunity to assess the effect of diet upon chronic degenerative disease. In the future, the Korean diet might be continue to change significantly These changes are being influenced by socioeconomic factors that have been emerging and growing stronger since mid-l980 and that probably continue to be potent. The expanded purchasing power of the consumer results in increased discretionary purchases. In the case of foodstuffs, the consumer demands appear to be directed toward items of higher protein content, which, being primarily animal products, are inevitably accompanied by an increased consumption of fat. The continued availability of these more expensive flood items depends upon the balance of foreign trade favouring their importation and domestic production. A regression of foreign trade could result in a decreased supply for the consumer, whereas continued growth of trade iou]d provide freedom for increasing availability to the consumer. In this latter situation the exact choice of foodstuffs is depending upon comsumer tastes and the pressures that may influence it.

  • A survey was carried out from July to December in 1979 and 1982 for the investigation of oceanographic conditions and phytoplankton in Seogwipo coastal area. Although a peculiar coastal sea water is formed by in flowing of fresh water, this is developed mainly in summer and disappeared or weakened in its strength after November. However, this coastal sea water covers only the surface while in mid and bottom layer open sea water is approached to the coast. Therefore, coastal and open sea water appears simultaneously in narrow sea area. Mean values of nutrient concentrates on surface layer during investigating period were $3.72{\sim}16.34{\mu}g-at/l$ in silicate, $1.98{\sim}5.53{\mu}g-at/l$ in nitrate and $0.34{\sim}0.90{\mu}g-at/l$ in phosphate. These showed slight differences among places but in general coastal side were lower than open sea side. Phosphates which is the lowest in concentrates among nutrients in Seogwipo coastal area shows almost similar value with Jinhae Bay but higher than open sea water around 10 mile south of Seogwipo. In general, seasonal changes of nutrients in investigating period shows a tendency of the lowest in October, increasing in November, and again slight decrease in December. As a phytoplankton fauna, 48 species, 1 variety and 2 breeds of Diatoms, 29 species, 3 varieties and 1 breed fo Dinoflagellates, and 1 species each of Chroococcus and Trichoceratium were found. Monthly predominant species are all neritic: Rhizosolenia sp. and Ceratium sp. in August, Chaetoceros sp., Ceratium sp. and Peridinium sp. in September, Astrionella sp. and Peridinium sp. in October, Astrionella sp., Navicula sp. and Chaetoceros sp. in November Among these, Rhizosolenia alata f. gracillima in August and Astrionella gracillima in November are remarkable predominant.

  • To better understand the physical processes that control the high-latitude lower thermospheric dynamics, we analyze the divergence and vorticity of the high-latitude neutral wind field in the lower thermosphere during the southern summertime for different IMF conditions. For this study the National Center for Atmospheric Research Thermosphere-Ionosphere Electrodynamics General Circulation Model (NCAR-TIEG CM) is used. The analysis of the large-scale vorticity and divergence provides basic understanding flow configurations to help elucidate the momentum sources that ulti-mately determine the total wind field in the lower polar thermosphere and provides insight into the relative strengths of the different sources of momentum responsible for driving winds. The mean neutral wind pattern in the high-latitude lower thermosphere is dominated by rotational flow, imparted primarily through the ion drag force, rather than by divergent flow, imparted primarily through Joule and solar heating. The difference vorticity, obtained by subtracting values with zero IMF from those with non-zero IMF, in the high-latitude lower thermosphere is much larger than the difference divergence for all IMF conditions, indicating that a larger response of the thermospheric wind system to enhancement in the momentum input generating the rotational motion with elevated IMF than the corresponding energy input generating the divergent motion. the difference vorticity in the high-latitude lower thermosphere depends on the direction of the IMF. The difference vorticity for negative and positive $B_y$ shows positive and negative, respectively, at higher magnetic latitudes than $-70^{\circ}$. For negative $B_z$, the difference vorticities have positive in the dusk sector and negative in the dawn sector. The difference vorticities for positive $B_z$ have opposite sign. Negative IMF $B_z$ has a stronger effect on the vorticity than does positive $B_z$.

  • Electronic wastes have increased tremendously. However, any reliable treatment methodologies have rarely been established. Electronic wastes have posed serious disposal problem due to their physico-chemical stability. This paper investigated the application possibility of pyrolysis for the purpose of recycling the p-CCL(phenol based Copper Clad Laminate). Thermogravimetric analysis(TGA) was used to investigate the thermal decomposition pattern of p-CCL. We elucidated the characteristics of pyrolysis by-products at operating temperatures of 280, 350 and $600^{\circ}C$. GC/MS and FT-IR were used to characterize the liquid by-products along with general characterization methods such as Ultimate Analysis, Proximate Analysis and Heating Value, whereas general characterization methods were only introduced for the solid by-products. At a heating rate of $5^{\circ}C$/min, TGA curves exhibited three decomposition stages: (1) low-temperature decomposition region$(<280^{\circ}C)$, (2) medium temperature region$(280\sim350^{\circ}C)$ and (3) high-temperature region$(>350^{\circ}C)$. The major compounds of liquid by-products at low- and medium-temperatures were accounted for by water and phenol, whereas branched phenols and furans were major compounds at high-temperatures. As the temperature increases, volatile quantities decreased but the fixed carbon increased. High heating values of solid by-products($7,400\sim7,600$ kcal/kg) would suggest that the solid by-products could be applicable as fuel. In addition, high fixed carbon but low ash content of the solid by-products offered an implication that they are capable of being upgradable for adsorbent after applying appropriate activating process.

  • Purpose: This prospective study was performed to evaluate the usefulness of preoperative radioimmunoscintigraphy and intraoperative scintimetric examination (radioimmunoguided surgery: RIGS) using $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment. Materials and Methods: Nineteen patients with rectal cancer underwent preoperative whole body planar scintigraphy at 4 hours after injection of $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment and SPECT imaging at 18 hours. Surgical operation was performed at 24 hours after injection. During laparotomy, radioactivities from intraabdominal viscera were measured by gamma probe. The radioactivities from excised tumor and lymph nodes were also measured and compared with pathology. Results: All nineteen patients were confirmed to have adenocarcinomas in the rectum. Twenty-seven of 97 excised lymph node groups had metastasis and 2 patients had liver metastasis in pathology Preoperative radioimmunoscintigraphy detected primary tumors in 11 patients (sensitivity 55%) and it could not detect any lymph nodes or liver metastasis. All patients showed high radioactivity in the kidneys, liver, spleen, and major vessels in intraoperative measurement by gamma probe, and tumor activity was not discriminated from background activity However, radioactivity from excised tumor was higher than normal rectum (T/B ratio; $3.47{\pm}2.25$). When excised lymph node activity/background activity ratio >1.5 was considered as positive criteria of metastasis, sensitivity, specificity, positive and negative predictive values were 78.6%, 73.9%, 55.0% and 89.5%, respectively. Conclusion: Radioimmunoscintigraphy using $^{99m}Tc-anti-CEA\;F(ab')_2$ has no additional value for preoperative staging and use of early RIGS using $^{99m}Tc-anti-CEA\;F(ab')_2$ is inappropriate. For early RIGS using $^{99m}Tc$ labeled antibodies in rectal cancer patients, further development of more specific antibodies and methods to reduce background activity are needed.

  • The purpose of this study was to examine the awareness of dental patients using dental institutions about dental hygienists in an effort to help educate dental hygiene students to have the right image of dental hygienists. And it's also meant to provide education for dental hygienists to develop their own capabilities, attitude and values to render quality medical services to patients. The subjects in this study were the patients who visited dental clinics and hospitals to receive treatment. A self- administered survey was conducted from March 5 to April 13, 2010, in consideration of their general characteristics. The answer sheets from 204 respondents were gathered, and 197 answer sheets were analyzed except seven incomplete ones. A factor analysis was carried out to find out their general characteristics, and independent-samples t-test and one-way ANOVA were utilized to get statistical data on mean and standard deviation. A SPSS 12.0 program was employed to analyze all the collected data. And it's found that the largest number of the patients thought that the main duty of dental hygienists was to give treatment to patients, and they took a favorable view of their services. They weren't well aware of the process of nurturing dental hygienists and their curriculum, and they put a relatively strong confidence in their treatment and had relatively favorable experiences with them.

  • In recent years, there have been opinions in which physicians are liable to the revocation of their medical license if they are sentenced to above a certain level for criminal charges regardless of the types of offenses. Accordingly, a revised bill of law was submitted in the National Assembly, and related discussions are thus expected to commence. Considering the morality and ethics or the level of the rule of law that the general public expects of physicians, as well as the license revocation system in other professional sectors, it is assessed that medical license revocation due to criminal convictions of physicians is appropriate to some degree. However, if a poorly devised system is established based on unrefined inferences or emotional judgements, unexpected side-effects are likely to arise. With regard to serious criminal acts that society generally perceives as unacceptable, it can be assessed that the revocation of physicians' licenses would appropriately protect the general public from threats. However, given the life-saving characteristics of high-risk medical practices, higher malpractice exposures, and social values, it is difficult to assess charges of professional negligence resulting in death(or in injury) and minor offences in the same manner as anti-social criminal offences are handled. Physicians need to be treated the same as any other professions. At the same time, they are engaged in administering medical treatment to patients in the face of great risks as professionals. Under the circumstances, a discussion on the introduction of a more specific and empirical system is needed by considering the intrinsic characteristics of medical treatment and the need for an equitable health and medical policy. Accordingly, based on the above judgment and perception, this study explores the code of ethics for physicians and medical license revocation related to criminal offences at home and abroad, and examines various legislative alternatives appropriate for the Republic of Korea. In doing so, the purpose of the study is to contribute to the development of a reasonable system for handling criminal offences by physicians.
