  • The distributions of phytoplankton assemblages and environmental factors in Jinhae Bay and their relationships were investigated to estimate the potential limiting nutrient for phytoplankton growth and community structure. In situ algal bioassay experiments were also conducted to assess the species-specific characteristics in phytoplankton responses under different nutrient conditions (control, N(+) and P(+) treatment). During the study periods, bacillariophyceae and cryptophyceae occupied more than 90% of total phytoplankton assemblages. Phytoplankton standing crops in the inner part of Masan Bay were higher than that of Jinhae Bay. The DIN:DIP ratio, pH and transparency showed the significant positive correlation with phytoplankton biomass. According to cluster and multidimensiolnal scaling (MDS) analysis based on phytoplankton community data from each station, the bay was divided into three groups. The first group included stations from the south-western part of Jinhae bay where cryptophyta species were dominated. The second group was distinguished from inner stations in Masan Bay. These stations showed low transpancy and high DIN:DIP ratio. The other cluster included the stations from the eastern part and central part of Jinhae Bay, which was characterized by the high DSi:DIP ratio and dominant of diatom species. Phosphorous (P) was limited in Masan Bay due to significantly increases in the phytoplankton abundances. Based on stoichiometric limitation and algal bio-assay in Jinhae Bay, nitrogen (N) was a major limiting factor for phytoplankton production. However, silicate (Si) was not considered as limiting factor, since Si/DIN and Si/P ratio and absolute concentration of nutrient did not create any potential stoichiometric limitation in the bay. This implies that high Si availability in winter season contributes favorably to the maintenances of diatom species.

  • Right to counsel means a defendant has a right to have the assistance of counsel (i.e., lawyers), and if the defendant cannot afford a lawyer, requires that the government appoint one or pay the defendant's legal expenses. The right to counsel is generally regarded as a constituent of the right to a fair trial. Historically, however, not all countries have always recognized the right to counsel. The right is often included in criminal law and constitutional law etc. First, any person who is arrested or detained shall have the right to prompt assistance of counsel. When a criminal defendant is unable to secure counsel by his own efforts, the State shall assign counsel for the defendant as prescribed by act in article 12(4) of the constitutional law. Second, the defense counsel or a person who desires to be a defense counsel may have an interview with the defendant or the suspect who is placed under physical restraint, deliver or receive any documents or things and have any doctor examine and treat the defendant or the suspect in article 34 of the criminal law. Nonetheless, problems about guarantee of the rights to counsel to the national security violators like spy terrorist and etc will be important for Koreans to consider. That is because national security violators's cases are qualitatively different from general criminal offense's cases and historically, lawyer obstruct a investigation in the process of examination of a suspect for national security violators. Therefore, this study suggest a way that a restriction the rights to counsel with an attorney in cases of the national security violators. To this end, in this paper, I touch on restriction of right to counsel during interrogation in the England and Germany etc in comparison to that of Korea and review Korea's Supreme Court decision and Constitution Court decision to understand the prospective and trends for Korean investigation procedure improvement.

  • Background : Despite the clinical clues of bronchial asthma, some chronic coughers fail to be diagnosed due to negative test results. This study was aimed at evaluating the diagnostic performance of routine objective tests and identifying a cost-effective approach for asthmatics with a chronic cough. Methods : Patients with a chronic cough of more than 3 weeks duration, and showing normal chest radiograph and spirometry were enrolled. On the first visit, objective tests, composed of serum total IgE, peripheral blood eosinophil count, spontaneous sputum eosinophil count, methacholine bronchial provocation test (MBPT) and paranasal sinus radiograph, were performed, with the simultaneous administration of oral prednisolone (0.5mg/kg) for one week. The final diagnoses were made on the basis of the test results, and the patients grouped according to their steroid responsiveness. The role of the etiologic diagnosis tests was evaluated, and the medical costs of the final management plan simulated with respect to three assumed models. Results : Sixty chronic coughers were finally analyzed. The final diagnoses were as follows: bronchial asthma 21.7%, eosinophilic bronchitis 6.7%, paranasal sinusitis 18.3%, presumptive allergy 8.3% and non-diagnostic case 45.0%. Ninety percent were steroid responder. With the bronchial asthma cases, the positive rate of MBPT was 38.5%, with sputum eosinophil count in 84.6%, serum total IgE in 38.5%, and a peripheral blood eosinophil count rate of 30.8%. When the test results and steroid responsiveness data were applied to the 3 models, the chest radiograph, spirometry, sputum eosinophil count and paranasal sinus radiograph test results, and simultaneous short term steroid treatment seemed to have acceptable diagnostic performances, which could be used as a further guide to cost-effective planning. Conclusion : Objective tests, composed of chest radiograph, spirometry, paranasal sinus radiograph and sputum eosinophil count, with simultaneous short term steroid treatment, are suggested as cost-effective approaches for asthmatics with a chronic cough.

  • Purpose: Bisphosphonates (BPs) are the analogues of endogenous pyrophosphates: they have been used in the treatment of skeletal diseases such as Paget's disease, osteoporosis, and tumorinducing ostelysis, and are used in treatment of osteolytic metastasis of breast cancer recently. They are also used as one of the therapeutic agents for metastasis of prostatic cancer of which metastasis makes the mixed nature of osteolysis and ostegenesis. Although the action mechanism of BPs are well known for diseases with excessive osteoclastic bone resorption, the direct effect of BPs has not been known yet. This study was intended to see the tumor suppression capability of Zoledronic acid(ZOL) using nude mouse with osteosarcoma. Materials and Methods: MG-63 and HOS osteosarcoma cell lines were used and the transforemed MG-63-GFP and HOS-GFP cells, which were made for detection under fluorescent light, were subcutaneously injected to make osteosarcoma. The five 6-week male mice were used for the experiment at each group. After the injection, mice were cultivated until tumor pieces grow up to $3{\times}3{\times}3$ $mm^3$ and ZOL of 120 ug/kg was subcutaneously injected twice a week. Sizes of tumor were measured twice a week and photographed under fluorescent light. Results: In in vivo test with HOS osteosarcoma cell lines, mean size of tumors was 2,520 $mm^3$ in control group and was 131 $mm^3$ in ZOL group, which showed 94% of reduction comparing with the control ; with MG-63 osteosarcoma cell lines, mean size of tumors was 2,866 $mm^3$ in control group and was 209 $mm^3$ in test group with 72% of reduction (p<0.05). Conclusion: In in vivo tests with nude mice, we suggest that ZOL has direct effect on osteosarcoma cells and it would be used as one of the therapeutic agents for osteosarcoma, especially to ZOL-sensitive osteosarcoma cells.

  • In vitro activities of Codonopsis lanceolata (CL) 70% ethanol extract and its fractions (hexane, chloroform, ethyl acetate, butanol and water) were examined by total polyphenol content, reducing power, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), 2,2-diphenyl-$\beta$-picrylhydrazyl (DPPH), and oxygen radical absorbance capacity (ORAC) assays. The ethyl acetate fraction from CL ethanol extract (CLEA) showed the highest total polyphenol content (22.7 mg/g) among five fractions, and also exhibited an excellent reducing power (0.42~1.27 at $250\sim1,000\;{\mu}g/mL$). CLEA at $100\sim400\;{\mu}g/mL$ concentrations had 27.7~70.3% of ABTS radical scavenging activity and the highest DPPH radical scavenging activity (81.6% at $400\;{\mu}g/mL$). CLEA had dominantly higher $ORAC_{{ROO}{\cdot}}$activity compared to other fractions. CLEA and butanol fraction had significantly higher $ORAC_{{OH}{\cdot}}$ activities than 70% ethanol extract, hexane, chloroform and water fractions. The CLEA exhibited the highest antioxidant activity in CL 70% ethanol extract and its fractions. Thus, effect of CLEA treatment on antioxidant gene expression under the oxidative stress conditions by a high fat diet in animal model was studied by microarray and RT-PCR methods. The 31 antioxidant genes were expressed but the genes were not up-regulated at least a two-fold by CLEA treatment. We concluded that CLEA does not have an indirect antioxidant effect but a direct antioxidant effect by up-regulation of antioxidant genes in high fat diet-induced obese mice.

  • Purpose: Routine pancreatico-splenectomy with total gastrectomy should no longer be considered as the standard surgical procedure for gastric cancer because of the lack of proven surgical benefit for survival. The aim of this study is to evaluate the clinicopathologic factors and the survival of patients with locally advanced gastric cancer and they had undergone combined pancreatico-splenectomy with a curative intent. Material and Methods: We retrospectively reviewed a total of 118 patients who had undergone total gastrectomy with distal pancreatico-splenectomy from 1990 to 2001. The patients were divided into 2 groups: 90 patients who were free from cancer invasion (group I), and 28 patients with histologically proven cancer invasion into the pancreas (group II). The various clinicopathologic factors that were presumed to influence survival and the survival rates were analyzed. Results: The rate of pathological pancreatic invasion was 23.7%. The tumor stage, depth of invasion, pancreas invasion, lymph node metastasis, lymph node ratio, curability and the hepatic and peritoneal metastasis were statistically significance on univariate analysis. Among these factors, the tumor stage, lymph node ratio and curability were found to be independent prognostic factor on multivariate analysis. The 5-years survival rates were 36.2% for group I and 13.9% for group II. The morbidity rate was 22.1%, and this included pancreatic fistula (5.1%), intra-abdominal abscess (4.2%) and bleeding (4.2%). The overall mortality rate was 0.8%. Conclusion: Combined distal pancreatico-splenectomy with total gastrectomy with a curative intent was selectively indicated for those patients with visible tumor invasion to the pancreas, a difficult complete lymph node dissection around the distal pancreas and spleen, and no evidence of liver metastasis or peritoneal dissemination.

  • Purpose: One of the critical aspects on dispensing glasses is to match the center of pupils to the optical center of lenses as the mismatched glasses are able to induce uncomfortable effects called prism which has been known to induce phoria, a main cause for asthenopia in many cases. Therefore, we investigated the induced prism occurred by mismatching centers between the center of pupils and the optical center of lenses. Methods: In this study, total 103 subjects were examined whether the center of pupils and the optical center of lenses are matched in horizontal and vertical directions, and then, the data was categorized into 4 groups based on the structural components of glasses. Total amount of prism was compared to show the effect of the glasses frame on the prism induction, and the value of measured prism was compared with the German RAL-RG 915 regulations. Results: The results in respect to the horizontal component showed that the induced prism was not found in 10.7% of total subjects. 73.8% of total subjects were influenced by induced prism, the range of prism was in a tolerance level. However, the 15.5% of total subjects seemed to be influenced by prism which is out of the criterion of tolerance. In case of vertical component, 23.3% of total subjects showed no effects of prism while early adopting glasses, 54.4% of total subjects showed a little prism effect within the criterion of tolerance, and 22.3% of total subjects showed the prism effect out of the tolerance range. This data indicates that group A and B that are less likely adjustable by fitting induce more prism than group C and D in horizontal and vertical components. Conclusions: In higher refractive error condition, it was found that aligning the optical center of lenses with the center of pupils by pre-fitting of glasses frame minimized prism induction in horizontal and vertical components, which ameliorates ocular fatigue. Therefore, appropriate optometric dispensing through fitting by opticians and precise design about monocular PD and monocular Oh are necessary to improve visual perception.

  • This study has been carried out to estimate mean concentration and the daily intake of 2 artificial sweeteners (aspartame and sucralose) by analyzing food samples. Total number of samples was 755 and the number of samples detected for sweeteners was 33 (detection rate was 4.4%). Contribution rate to total estimated daily intake (%) of artificial sweeteners in food categories was high in candy for aspartame and sucralose. Total Estimated Daily Intakes $({\Sigma}EDI)$ for different age groups were high in $13{\sim}19$ years old for aspartame and $7{\sim}12$ years old for sucralose. Total estimated daily intakes $({\Sigma}EDI)$ of men and women were 5.10 mg/person/day and 4.88 mg/person/day, respectively. Total estimated daily intakes $({\Sigma}EDI)$ of artificial sweeteners were shown as follows; 3.75 mg/person/day for aspartame and 1.27 mg/person/day for sucralose, respectively and assuming a body weight of 55 kg. These values were ranged from $0.15{\sim}0.17%$ of acceptable daily intake (ADI) evaluated by FAO/WHO and $1.0{\sim}21.4%$ of theoretical maximum daily intake (TMDI), and therefore, judged to be safe.

  • This paper aims to show the various aspects of migration in Kwangju merropolitan area, southwestern Korea, for a period of years 1980-1985. Migratory patterns are spatially extensive in countryside around Kwanfju, and due to high accessibility to the metropolitan area urban implosion emerges in the city. In Chonnam province where Kwangju is loca-ted, all cities and counties except for such in-dustrial areas as Yochon, and Kwangyang are experiencing population losses in terms of net migration by survival rate methods. Kwangju is the exceptionally one of in-migration areas in Chonnam, though its central part(Dong-Gu) is also an out-migrated area. Predominantly in-migration urban areas have high proportions of a student age group between 15-19 years, and that reflects the importance of the educational factor in migration analysis. The municipal authorities of Kwangju are planning to block the way of the middle sxhool students who live in the outskirts of Kwangju to entrance to high school in the city. Thant may stir up migrations into Kwangju for the elementary and middle school students, because the city id expected to provide educational opportunities higher and better than remaining Chonnam areas. Population of Kwangju would, therefore, grow as the students migrate into the city. The findings on the residential intra-city movement in selected 5 Dongs indicate that implications of a short-distance movement re noteworthy; neighbour to neighbour, and the nearest stop in the way from the outer Kwangju as well. Trends in a short-distance movement are in accord with Ravensteins's "law of migra-tion". But in casw of the inter-provincial migra-tion to Kwangju, the number of in-migrants from remoter Seoul is more than that from nearer Chonbuk province. Therefore it supports the fact that the movement between capital region and far off local cities overcomes a distance barrier. The temporary mobility for a day has been increased as the standard of living has improved and it reaches a peak on weekend or on con-secutive holidays. The number of temporal movers to Kwangju from capital region and Yongnam area, southeastern Korea has a greatincrease in terms of the frequency of the passengers' mobility, in particular on Myongjol(the ethnic and traditional festival day) in com-parison with on weekdays. By comparison with two largest Myongjols, the number of movers is more on Chusok(The Full Moon festival on lunar August) than on Sol (lunar new year's day). Annual peak point of weekday movers appears in August because of summer vacation. But the lowest one appears in June, which is related to the busy farming season. A patients' move for medical services in on the increase with a change of living conditions. It is especially true in the industrial counties such as Kwangyang and Yochon. By way of conclusion, it should be pointed out that one of the problems we face in survey of migration volume by the survival rate method is that the survival rate somtimes exceeds the value 1.0, in normal states of which should be under 1.0. it may be due to the shortcoming from the census statistics. We should not give therefore too much stress on the importance of migrations or moves as an element of changes in spatial pattern. In cinclusion, the results of the study show some geographic facts as the followings: 1. One of the outstanding phenomena in all types of movement is the seletivity of ages. The most important factors are related to education and employment. 2. Short-distance movement is carried out in accordance with Ravenstein's law, but in case long-distance movement, in-migration from capital region is prominent in spite of remoten-ces. The gravity between large cities such as Kwangju and Seoul, which has a frequent human movenent, causes urban implosion of small cities between those cities. 3. The temporary mobility for a day, in con-trast to that of permanent movement, is more related to transportation, and its volumes and annual variations are a large-scale. 4. Passengers' mobility is high in industrial cities. And the scope of patients' mobility is narrower than passengers'.
