The purpose of this study was to propose the developmental direction for small libraries based on a set of various situational analysis of small libraries in Seoul. By analyzing the operational status of the autonomous regions of different operating methods, we also pursued qualitative enhancement of small libraries by autonomous district by proposing optimized operation methods. As a consequence of the study, it was analyzed that the public and private libraries need to be distinguished in consideration of the characteristics of operation according to the operating entity rather than uniform budget support and guidance management. That is, the small libraries scattered throughout Seoul were founded by the principal of their establishment for the purpose of providing knowledge information and reading culture service within the public activity area. Therefore, if Seoul intervenes and manages under the current situation, where the libraries are operating independently in accordance with the purpose of establishment, regardless of whether they meet the user requirements or not in terms of quality or quantity, various problems may be caused. In this background, it seems appropriate to restrict the library management in line with relevant regulations.

In bulding Intelligent Agent Societies (IAS), it is very important to design and implement coordination in accordance with the known requirement and anticipated working conditions. Coordination consists of a set of mechanisms necessary for the effective operation of IAS. Currently, there is little theoretical support that could help in this research is to generate an empirically-based solving systems in which all agent share an identical goal structure and fully cooperate. And we developed a simulation model called "P-System" which produces basic data to be used for statistical analysis to generate a theory of coordination. Coordination among agent in the P-System is dependent on 23 control variables calld TEs(tweakable emtities.)And the level of coordination is represennted by an independent variabe called QMC (Quality Measure Coordination) expressed in numerical terms according tn the definiion of this study. Also, we have studied how to select unbiased subset from the huge total experimental space of the P-System and how to decide the scale of the subset.

The purpose of this study is to suggest the landscape potential index for visualizing landscape information in the conservation of hilly landscape in urban fringe. For the visual and quantitative approach to topological landscape assessment, numerical entity data of DEM(digital elevation model) were processed with CAD-based utilities that we developed and were mainly focused on analysis of visibility and visual sensitivity. Some results, with reference in assessing greenbelt area of Eodeung Mt. in Gwangju, proved to be considerable in the landscape assessment of suburban hilly landscapes. 1) Since the viewpoints and viewpoint fields were critical to landscape structure, randomized 194 points(spatially 500m interval) were applied to assessing the generalized visual sensitivity, we called. Because there were similar patterns of distribution comparing to those by 56 points and 18 Points given appropriately, it could be more efficient by a few viewpoints which located widely. 2) Regressional function was derived to represent the relationships between probabilities of visibility frequency and the topological factors(topological dominance, landform complexity and relational aspect) of target field. 3) Visibility scores of each viewpoint were be calculated by summing the visual sensitivity indices within a scene. The scores to the upper part including ridge line have been more representative to overall distributions of visual sensitivities. Also, with sum of deviations of sensitivity indices from each single point's specific index to the weighting values of view points could be estimated rotationally. 4) The deviational distributions of visual sensitivity classes in the topological unit of target field were proved to represent the visual vulnerability of the landform. 5) Landscape potential indices combined with the visual sensitivity and the DGN(degree of green naturality) were proposed as visualized landscape information distributed by topological unit.

The 'Grand Challenge' in the global level raises fundamental questions on the role of private firm as a profit maximizer. From the new perspective, firms are recognized as a social entity with social and environmental responsibility. Particularly, the importance of transition-orineted firms, which pursue an objective of socio-technological system transition, have increased. These environmental changes request a new understanding on the identification of firms and the evolution of sustainable business model from the technological innovation perspectives. This paper aims on the new understanding on the motivation of firms who participated on the sustainable system transition and the proposal of 'transition-oriented firms' concept. Based on literature survey, this paper reviews the role of firms in the process of socio-technological system transition, the cases of transition-oriented firm, the types of sustainable business models and their strategies.

Qi. in ancient east Asian Philosophy and medicine, was the quintessential concept symbolizing material orgin of the world. It was considered as the original matter of the world, and the genesis, development and extinction of everything in heaven and earth was explained through the movement of Qi. Despite its importance, the interpretation of Qi has brought about various bifurcations in the history of Oriental medicine. It is comprehended either as ideal concept, or as actual entity. Also, there exists synthetic idea of considering both sides of Qi. These ideas results from obscure understanding based on textual interpretation apart from actual experince. When experincing Qi through discipline, however, man can understand Qi concretly and actually and even grasp the explanation of the cosmos and life. One problem of Qi discipline was that it couldn't ascend the stage of subjective experience. Now, with the method of 'Hanalmomjit'. a developed form of zifadonggong(自發動功), I could reach coherent results to offer the foundation of objective understanding of Qi. The testees, disciples of Hanalmomjit, could express the characters of herbs in their Qigong actions, and the expression was meaningful and coherent to be considered as expressing the effects described in the classics of herbalogy. This result comes from the capacity of grasping external Qi-status, not only expressing the internal communication of jingluo(經絡) in Hanalmomjit.

Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms ; and the constellation of symptoms has been called laryngopharyngeal reflux (LPR). In the absence of definite diagnostic criteria, LPR disease remains a subjective entity. A diagnosis of LPR is usually based on response of symptoms to empirical treatment. Investigative modalities such as pH monitoring and, more recently, impedance studies are generally reserved for treatment failures. LPR usually requires more aggressive and prolonged treatment to achieve regression of both symptoms and laryngeal findings. The suppression of gastric acid and secretion with anti-secretary agents has been the mainstay of medical treatment for patients with acid-related disorders. The suppression of gastric acid secretion achieved with Hz-receptor antagonist $(H_2RA)$ has proved suboptimal for relief of reflux symptoms. The rapid development of tolerance and rebound acid hypersecretion after the with-drawal of $H_2RA$ limit their clinical use. Proton pump inhibitors (PPI) have been proved to be very effective for suppressing intragastric acidity, but the optimal dose and duration is unknown. Current evidence indicates that pharmacologic intervention should include, at a minimum, a 3 month trial of twice daily PPI. Symptoms of LPR improve over 2 months of therapy. The physical findings of LPR resolve more slowly than the symptoms and this continues through out at least 6 months of treatment. For most patients with LPR, twice daily dosing with a PPI is usually recommended for an initial treatment for a period of no less than 6 months treatment, and lifetime treatment may be required.

Pesticides are extensively used for the control of crop pests in agriculture and forestry. Organophosphate (OP) and carbamate pesticides are especially effective for the control of a variety of harmful insects. However, these cholinesterase inhibitors are also dangerous to non-target organisms (wildlife and other animals) because of their high acute toxicity. Most poisonings by pesticides occur as a result of misuse or accidental exposure, but intentional killing of unwanted animals also occurs. At the request of a local autonomous entity, we investigated wild bird poisonings by pesticides from 2003 to 2007. The 207 suspicious samples of pesticide poisoning based on the necropsy were analyzed by GC/NPD, GC/FPD, or GC/MSD. We looked for trends in the identification of pesticides in wild birds thought to have died from poisoning. Pesticides were determined in 59% of the total samples analyzed. Phosphamidon and monochrotophos were the most common pesticides identified, which amounted to 77% of the subtotal. Other OP and carbamate pesticides were also found in various concentrations from dead wild birds. The determined rates of pesticides were as high as 86% and 76% in 2003 and 2006, respectively, during an outbreak of avian influenza in Korea.

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation. With the biopsy and computed tomography, it was confirmed that fistula and basal cell carcinoma. However, the connection between the fistula and skin cancer was not clear. Positron emission tomography-computed tomography scan was performed and was not detected as other local or distant metastasis. After that, wide excision of the skin lesion was performed. Although skin cancer is not commonly observed, it is necessary to rule out this disease entity by performing biopsy of skin lesions.

The Pierre Robin sequence (PRS) is the nonrandom association of micrognathia, cleft palate, and glossoptosis, leading to respiratory and feeding difficulties that appear neurogenic rather than mechanical in causation. Genetic determinants are thought to underlie this functional and morphological entity, based on the existence of Mendelian syndromes with PRS. Here, we demonstrate the association of PRS with trisomy 8p due to duplication of a segment as the karyotype 46,XX,dup(8)(p21.3p23.1) and confirm the additional materials as chromosome 8 via whole chromosome paint probes. Our observation supports the hypothesis regarding a genetic basis for nonsyndromic PRS, strengthens the possible genetic association with isolated cleft palate, and provides a candidate PRS locus in chromosomal region 8(p21.3p23.1).

Critical prediction models that determine whether a design entity is fault-prone or non fault-prone play an important role in reducing system development cost because the problems in early phases largely affected the quality of the late products. Real-time systems such as telecommunication system are so large that criticality prediction is more important in real-time system design. The current models are based on the technique such as discriminant analysis, neural net and classification trees. These models have some problems with analyzing cause of the prediction results and low extendability. In this paper, we propose a criticality prediction model using fuzzy rulebase constructed by genetic algorithm. This model makes it easy to analyze the cause of the result and also provides high extendability, high applicability, and no limit on the number of rules to be found.
