  • Despite the growing numbers of regional problems (e.g. conflicts between the state and localities, inter-local conflicts, etc.) associated with the state-led developmental projects, the Korean social sciences have been unable to offer satisfying explanations and solutions to the regional problems. This is mainly because the existing works, which have been taken captured by the assumptions of "methodological nationalism", significantly lack the socio-spatial understandings of the state actions and the relations between the state and localities, thereby seeing the issues of regional development mainly in terms of either the economic efficiency defined at the national scale, or the plan rationality of the national bureaucrats. With this problem orientation in mind, this paper aims to explore the ways in which the state and localities are interacting, conflicting and negotiating with one another through the mediation of the state-led developmental projects. Focusing on the developmental processes of Masan Export Processing Zone from the mid-1960s to the early 1970s, it examines the multi-scalar processes through which the state-led industrial complex developmental processes have been influenced by the complex and dynamic interactions among social forces and actors acting at diverse geographical scales (e.g. the global, national, local, urban, etc.). This analysis shows that the regional policies of the Korean developmental state were more heavily influenced by the interactions, contestations, and collaborations among social forces and actors, acting in and through the state, at various geographical scales, rather than by the economic and techno-bureaucratic rationality.

  • Odontomas are the common type of odontogenic tumors and generally are asymptomatic and frequently lead to impaction or delayed eruption of permanent teeth. They are composed of enamel, dentin, cementum and pulp tissue and are divided into compound and complex according to the morphology of the hard tissues. Compound odontomas consist of varying numbers of small toothlike structure and have a predilection for the maxillary anterior regions. Complex odontomas consist of an unorganized mass of odontogenic tissues and comprise approximately 25 percent of all odontomas and have a predilection for the mandibular posterior regions. The etiology of odontomas is uncertain but hypothesized to involve local trauma, infection and genetic factors. Treatment of odontoma is conservative surgical removal and are little probability of recurrence. These two cases were about the patients with delayed eruption of mandibular first molar and mandibular lateral incisor. We surgically removed odontoma, exposed impacted tooth and guided impacted tooth into normal position by orthodontic traction. At the completion of traction, the mandibular first molar and mandibular lateral incisor was positioned fairly within the arch and complications such as root resorption were not observed.

  • Objectives : The aim of this study was to evaluate the relation between the state of dental health(number of natural teeth) and nutritional status of Korean elderly using Korean Dietary Reference Intakes, which was an objective standard for nutritional intake based on database of Korea National Health and Nutrition Examination Survey, large scale of sample obtained by the government. Methods : Complex sampling procedure was used to analyze the fourth data(2007-2009) of Korea National Health and Nutrition Examination Survey. When preparing planning file, the estimator of variance as a stratification variance (variance name : kstrata), population of survey unit as a cluster variance(variance name : PSU), and previous exam and nutritional related weighted as a weighted were analyzed by considering reproduced survey and nutritional related total weighted. Complex samples chi-square test was used to estimate the relation between number of natural teeth and inadequate intake and relation factors included in the model were analyzed by complex samples logistic regression analysis. Results : The group of edentulous had a higher risk to intake less nutrient, except calcium, riboflavin and vitamin C than recommended level comparing to reference group which had natural teeth more than 20(phosphate : OR=1.763; 95% CI=1.273-2.443, thiamine : OR=1.748; 95% CI=1.276-2.395, protein : OR=1.610; 95% CI=1.213-2.138). Conclusions : The number of teeth in Korean elderly over 65 years old had a relation with nutritional status in this investigation. Especially, intake level of nutrients was different between the edentulous group and the reference group. Therefore, dental health care is needed from young and middle age to keep health dental condition for through whole life as well as old age. Although the dental condition of the aged is not good, it is evitable to educate them about the relation between dental health and nutritional ingestion to take balanced nutrition, we think.

  • The Pancreatic islet are the clusters of endocrine cells scattered through out the exocrine pancreas. Transplantation of a sufficient pancreatic islets can normalize blood glucose level so that may prevent devastating complications of type I diabetes(IDDM) and other side effects of the IDDM. Recently, there are several approaches to transplant sufficient pancreatic islet, and it was comprised in increase or regeneration of the endogenous $\beta$-cell mass from donor's pancreas, but relatively few studies have been devoted to the morphological characters of the isolated and 3 day cultured pancreatic islets. We investigated morphological pattern of intracellular structure of isolated and 3 day cultured pancreatic islets. The morphological characters of the pancreatic islets were observed by scanning electron microscope and transmission electron microscope, and insulin distribution of the each islets were observed by transmission electron microscope, and were labeled with insulin antibody. Intracellular structures including nuclei, mitochondria, RER, Golgi complex and many secretory granules were normally appeared in the isolated pancreatic islets which was extracted immediately dornor's pancreas, however, There is a significant morphological changes between the 3 day cultured pancreatic islets and isolated islets. 3 day cultured pancreatic islet's $\beta$-cells had normal nuclei but increased cytoplasm mass and RER and developed Golgi complex. Insulin secretory granules were decreased in numbers rather than isolated pancreatic islet. In this study, the pattern of intracellular structure variation was examined during pancreatic islet culture. Most distinct features are variation of the insulin secretory granules, and developed RER, and dilated golgi complex. Therefore, we suggested that the various change of the morphological characters on cultured pancreatic islets were responsible for the function(biosynthesis and secretion of insulin) and growth. These results were also cultured islets have greater ability to recover and maintain normoglycemia than isolated islet transplantation.

  • The sequence data of the plastid DNA (trnL-F IGS, trnL intron, and trnH-psbA) and nuclear DNA (RNApol2_i23) markers were utilized to study phylogenetic relationships among the taxa in the Polygonatum odoratum complex (Ruscaceae). European P. odoratum individuals form a clade with a high bootstrap value, which is a sister to the clade of Korean P. odoratum var. odoratum, P. odoratum var. pluriflorum and P. robustum. The formation of the clade with P. odoratum var. odoratum, P. robustum, and one accession of P. odoratum var. pluriflorum indicates geological speciation in isolated populations in the islands following dispersal events from the mainlands. All data sets form two major clades, which are congruent with the subgroups divided by the basic chromosome numbers (x = 9 and x = 10). Although it is not easy to test the hypothesis of the decrease in the basic chromosome number due to scatter taxon sampling in this study, the molecular data strongly suggested that aneuploidy plays an important role in lineage diversification in the genus Polygonatum. The cytological data was not strongly supported by the cpDNA sequences. Further investigations of the cytological, morphological, and geographical characteristics with comprehensive sampling are desired to understand the evolution and lineage diversification in the genus.

  • We studied the relationship between each type which was figured out by the question paper given to the patients who chiefly complained feeling of cold and Sasang constitution. The results are as follows. 1. Diagnoses in woman's disease with feeling of cold(冷病) are abdomnal mass(uterine myoma, ovarian cyst), dysmenorrhea, leukorrhea and infertility, orderly in number. They have commoness in the origin of disease which are stagnation of Qi(氣滯) and blood stasis(血瘀), cold(寒), damp(濕) and we can find the causes of feeling of cold are stagnation of blood(血瘀) and harmness of damp(水毒). 2. In the type of survey through the question paper, the largest number of the origin of that disease is cold, the next is blood stasis and dificiency of Qi(氣虛), dificiency of blood(血虛), stagnation of Qi, damp phlegm(濕痰) etc. 3. (1)The numbers by constitutional assortment of object are like this. Taeumin are 23 persons,Soumin 14 and Soyangin 6, so we can find the feeling of cold turn up evenly in all constitution but the number of Soyangin was relatively small. (2)The inclination of constitutional type is the highest in Soumin and they often have and feel strongly disorders of their body. (3)We could find the corelation of theoretical background of Sasang Medicine in constitutional type of survey. 4. (1)The numbers by constitutional assortment of the patients with feeling of cold and numbness(冷痺症) are like this. Taeumin are 16 persons, Soumin 7 and Soyangin 3, as are like the distribution of 3-(1). (2)The inclination of constitutional type is the highest Soumin, so they have multiple type of differentiation of symptoms and signs and their symptoms is old and severe, therefore they need long time for cure. In all, except the symptom with feeling of cold caused by dificiency of the blood and insufficiency of yang(氣虛와 陽虛) that we meet frequently on clinic is numerous, the number of that caused by stagnation of Qi and blood(氣滯와 血滯) alike dysautonomia is also large. And we can find the feeling of cold turn up evenly in all constitution but the number of Soyangin was relatively small. Within the case of Soumin, they have both dificiency of Qi and blood, have complex source, so their symptoms are old and severe and they need long time for cure. In Taeumin, they are of large number with dificiency of Qi and we think thst that are concerned with the symptom of exterior cold.

  • Along with a general growth in living standards there has been a corresponding increase in the demand for tourism. Cruise based tourism, in particular, has become one of the most dynamic and dramatic growth sectors in the tourism industry over the last 20 years, including in the Northeast Asian region. In line with the growth of passenger numbers, the number of cruise ships and their berth capacities has increased significantly since the late 1970s. Korea, as a peninsular nation, has also experienced a rapid growth in cruise passenger numbers. The national economy has greatly benefited from this as the industry acts as an income generator, creating new jobs and potential investments and in developing local tourism. Ports play an important role in the development of any national cruise industry, providing not only ship berths but supply and bunkering facilities and a gateway to local tourism opportunities. The selection of the optimal cruise port location is an important and complex problem because the decision makers have to consider a large number of criteria which have a significant effect on the economy, environment, human life, and society. This paper investigates those criteria that are significant in developing a successful cruise port by employing a questionnaire survey of major cruise port users - shipping companies and tourism companies. The ports, surveyed in this study are Busan, Incheon, Yeosu and Jeju. All have been identified as important potential cruise ports in the Korean Government's 'The 3rd Port Basic Plan (2011-2020)'.

  • This study was carried out to investigate the effects of Opuntia ficus-indica complex (OF) on blood glucose, glucose tolerance, plasma insulin level and histopathological appearance of pancreatic islets in streptozotoxin (STZ)-induced diabetic rats. Thirty-two male Sprague-Daweley rats were divided into non-diabetic control (NC), diabetic control (DC), diabetic OF of 2% (OF-2) and diabetic OF of 5% (OF-5) and fed experimental diets for 3 weeks. Compared to the DC group fasting blood glucose levels in the OF-2 and OF-5 groups were significantly (p<0.05) reduced while fasting plasma insulin level in the OF-2 and OF-5 groups were significantly (p<0.05) increased. Glucose tolerance in the OF-2 and OF-5 groups were improved. Histopathological observation of pancreatic islets of the OF-2 and OF-5 groups showed hyperplasia which was very similar to NC. Numbers of ${\beta}$-cells in OF-2 ($47.81{\pm}0.92$) and OF-5 ($81.64{\pm}2.80$) were higher than numbers of ${\beta}$-cells in DC ($13.18{\pm}1.01$). These results imply that the intake of OF improves ${\beta}$-cell proliferation and prevents the death of ${\beta}$-cells in STZ-induced diabetic rats.

  • Diagnosis and Prediction of urban industrial structure is a key subject for establishment of sustainable urban development plan. By this time, studies of industry-related urban spatial structure have been concentrated on measurement of space distribution by industry type mainly using data about urban industries or total worker numbers. Now, status of workers become an important issue so this study analyzed qualitative change of urban industrial structure in the view of space using work status classification system. For that, data for work status in 1994 and 2004 were collected in towns and villages, and space analysis units were coincided based on change data between 1994 and 2004. Then, it analyzed spatial distribution pattern of employment through qualitative standard called work status using GIS. The analysis results by work status type of Busan industrial structure in GIS circumstance were as below. First, traditional labor intensive industries met a limit and service and wholesale/retail sale industries went to be poor livelihood. Therefore, Busan's employment rate should be decreased and worker numbers were statistically increased, however, irregular and non-wage workers were suddenly increased. So, it was determined that the quality of employment in Busan area came down. Second, a traditional downtown area has dwindled; on the other hand, employment has been increased in new town or new industrial complex and in the area developed services rather than the manufacturing industry. It is expected that the result of this study may be meaningful as data to prepare for longterm industrial development plan through qualitative evaluation called work status as well as to make behavior pattern of industrial structure which is basis of urban development.

  • Purpose: At present, information regarding periodontal disease in geriatric patients is scarce. The purpose of this study was to quantify the periodontal pathogens present in the saliva of Korean geriatric patients and assess the relationship between the bacterial levels and the periodontal condition. Methods: Six putative periodontal pathogens were quantified by using a real-time polymerase chain reaction assay in geriatric patient groups (>60 years) with mild chronic periodontitis (MCP), moderate chronic periodontitis (MoCP), and severe chronic periodontitis (SCP). The copy numbers of Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, and Prevotella intermedia were measured. Results: It was found that the bacterial copy numbers increased as the severity of the disease increased from MCP to SCP, except for P. intermedia. For P. intermedia, it was found that samples in the MCP group yielded the largest amount. It was also found that the quantities of P. gingivalis, T. forsythia, and T. denticola, the so-called "red complex" bacteria, were lower than those of F. nucleatum, A. actinomycetemcomitans, and P. intermedia in all of the samples. Conclusions: Collectively, the results of this study suggest that the levels of P. gingivalis, T. forsythia, F. nucleatum, and T. denticola present in saliva are associated with the severity of periodontal disease in geriatric patients.
