This study deals with actual commuting distance and influence of risk factors depending on commuting distance and mode in order to reestablish actual commuting zone of primary school students. Data mining analysis(CHAID) was applied for this reestablishment using survey results from 6,927 primary school students in Seoul Metro. Six risk factors; convenience level of commuting path condition, convenience level of road crossing condition, vehicle speed on commuting path, segregation level between commuter and vehicle, congestion level of commuting path, and public security level and two mode; walking and cycle are considered in the analysis. As the results of CHAID analysis, commuting distance was divided into four zones; Internal Zone(0.491km under), External Zone(0.492 ~ 1.492km, 1.493 ~ 2.699km), Commutable Zone(2.70km over), and awareness level on safety is declined as commuting distance is increased. The risk factor affecting on safety is recognized differently by students depending on commuting distance and mode. For students commuting by walking, vehicle speed on commuting path and convenience level of commuting path condition are recognized as the prime risk factor within Internal Zone and Commutable Zone, respectively. For students commuting by cycle, convenience level of road crossing condition and vehicle speed on commuting path are recognized as the prime risk factor within Commutable Zone. Analysis results show that improved plan and program for commuting path for primary school students are required considering actual commuting distance and method.

Ever more so than any other times, today's corporations today face an ultimate issue of acquiring highest work expertise for their employees. However, most of current academic researches try to focus on what factors comprise an expertise while they fail to tackle the very issue of detailed numerical measurement of the expertise factors recommended improvement paths, and goals for each measured expertise level. Hence, this study suggests more objective and highly reliable identification of work competence measurement factors and the correlation among the identified factors. For details, it tries to propose a methodology of expertise measurement by developing into the definition of experts and expertise, reestablishment of expertise factors, determination of reference points of the expertise factors, and weighting of the factors. This measurement methodology finds that it itself has significant correlation with existing work competency level measurement and test tools. Therefore it is identified to justify its effectiveness. Finally, this study proposes an action point of establishing a national expertise architecture and its frameworks for various societies in general.

Purpose - This study proposes a strategic model for the late mover to effectively penetrate an industry that is dominated by a leading company. Thus, this study presents strategic implications for several late movers in overcoming the advantages of the leading company. Research design, data, and methodology - This study begins with a literature review followed by the formation of a strategic model that consists of: Repositioning, Utilization of Competence, Strategic Leadership, and Innovation. Specifically, this research analyzes LG Electronics (LG) as an example and investigates how LG infiltrates and grows in the water purifier market, overcoming the advantages of the powerful leading company. Results - The major steps taken by LG are summarized into four. First, LG studied the market, which had been conventionally treated as a single market. To penetrate the market, LG founded a new, special market segment. Subsequently, LG further segmented the market, executing a marketing strategy for each segment. Second, the unbending will of top managers was a key factor that addressed the challenge persistently. Third, even though LG was the late mover in the water purifier market, it had several technology competences such as compressor, refrigeration cycles, and algorithms. LG had profound knowledge in technology and used it effectively. Fourth, LG created a premium market through three innovative and distinguished factors such as the stainless water tank, sterilization service, and luxury design. Conclusions - This research draws four key findings from the example of the late mover in the water purifier industry: the reestablishment of a strategic position based on environmental change is an effective strategy for the late mover; strategic leadership is an important motive to generate late mover performance; and the late mover can utilize its existing knowledge and resources to overcome the first mover, such as presenting new added value compared to existing products as an effective catch-up strategy. Consequentially, through the study of performance determinants and the market penetration strategy of the late mover, this research has significance in providing basic material for companies trying to penetrate the market.

Purpose: A congenital lacrimal sac fistula is unusual and consists of a dimple opening below the medial canthal tendon that leads to the lacrimal sac. This anlage ducts occur when the lacrimal anlage cells proliferate and canalize rather than involute. And, the anomaly is usually not associated with any systemic abnormalities. Also congenital cleft of the earlobes is rarely seen among congenital ear anomalies. Therefore, we report rare case with symptomatic bilateral lacrimal fistula with the ear cleft. Methods: A 4-year-old boy was admitted with aggravated chronic maxillary sinusitis, recurrent chronic dacryocystitis, and epiphora. He had two minor anomalies including bilateral lacrimal fistula originated in lacrimal tear sac and unilateral transverse ear cleft. The patient had been operated with fistulectomy and perioperative antibiotics. A small vertical ellipse is made around the opening with sharp dissection. The tract is excised using the probe as the guide. Another probe is placed through the lower canaliculus to prevent the damage. A suture ligature of 6-0 Maxon is placed around the deepest point of the tract, which is then excised. Additional sutures are placed in the tissues to form a tight closure to prevent reestablishment of the fistula. The skin is closed with 6-0 Black Silk. Results: The patient recovered well without any complications such as infection, epiphora, and obstruction of lacrimal sac. Conclusion: Our case illustrates bilateral lacrimal anlage ducts in a patient with unilateral congenital ear cleft. We recommend careful evaluation of lacrimal system in these patients, especially bilateral case and other congenital anomalies. Finally, we recommend excision of the ducts when epiphora, infection, or chronic skin irritation occur.

Purpose: Microvascular free tissue transfer has become a reliable technique for the reconstruction of complex wounds. Occasionally, unexpected intraoperative thrombosis and/or spasm of recipient artery might be annoying problems even for the technically competent microvascular surgeons. If such problems are not treated properly, they will inevitably cause to flap failure. Methods: From January 2006 to February 2007, soft tissue reconstructions by free tissue transfers were performed on 21 patients having complex defects in the lower extremity. Although segmental revision and various pharmacologic agents were repeatedly applied, arterial occlusions were not managed in 6 cases. For removal of thrombi and release of spasm, Fogarty No. 2 or No. 3 catheters were inserted into the lumen to the proximal recipient artery. Its balloon was then inflated after passing through a resistant area. Next, the catheter was gently withdrawn backward. Results: After the Fogarty catheter was inserted two or three times, the pulsatile arterial flow was restored. When the catheter was inserted into the lumen, a feeling of resistance existed in a 5-10cm more proximal portion that could not be easily accessed from the vascular end. After the reestablishment of blood flow, successful anastomoses were achieved and immediate rethrombosis or spasm did not occur. No long-term sequelae associated with balloon trauma to the arterial wall were observed. Conclusion: The use of the Fogarty catheter can be an effective method in treating pedicle thrombosis and spasm. This is a very simple and rapid technique that offers microvascular surgeons another option to increase the success rate of microvascular anastomosis in free tissue transfers.

To determine whether pattern recognition based on metabolite fingerprinting for whole cell extracts can be used to discriminate cultivars metabolically, leaves of nine commercial Orostachys plants were subjected to Fourier transform infrared spectroscopy (FT-IR). FT-IR spectral data from leaves were analyzed by principal component analysis (PCA) and Partial least square discriminant analysis (PLS-DA). The dendrogram based on hierarchical clustering analysis of these PLS-DA data separated the nine Orostachys species into five major groups. The first group consisted of O. iwarenge 'Yimge', 'Jeju', 'Jeongsun' and O. margaritifolius 'Jinju' whereas in the second group, 'Sacheon' was clustered with 'Busan,' both of which belong to O. malacophylla species. However, 'Samchuk', belong to O. malacophylla was not clustered with the other O. malacophylla species. In addition, O. minuta and O. japonica were separated to the other Orostachys plants. Thus we suggested that the hierarchical dendrogram based on PLS-DA of FT-IR spectral data from leaves represented the most probable chemotaxonomical relationship between commercial Orostachys plants. Furthermore these metabolic discrimination systems could be applied for reestablishment of precise taxonomic classification of commercial Orostachys plants.

The purpose of this research focuses mainly on the establishment of: the image of the police that can be adopted to meet the demands of reality through the development of the design of policewomen's uniform in the times that require reestablishment of the image of the police; the image of the police that is appropriate for the organic structure of the society; and the image of the police that cooperate with the citizens. For background research I have considered the police and their uniforms from a theoretical point of view and have examined the process by which Korean policewomen's uniforms have changed. Actual research was carried out policewomen of Seoul Regional Police Station, was conducted and the results were utilized to figure out what the problem was. This research suggests an improvement measure by making four suits of summer and spring-and-autumn work-uniforms, and six suits of spring-andautumn and winter full-dress uniform. First the colors of work-uniforms and full-dress uniforms are not blue, which incites a feeling of coldness and stiffness, but are colors that are feminine and emit warmth---red, ivory, khaki, black, and beige. second pure, natural fiber is difficult to wash and is not an appropriate material for policewomen's uniforms when considering its cost and etc., fabrics that are a mix of synthetic fiber and natural fiber were chosen. Because mixed fabrics are cheaper and their ability to maintain shape is superior to that of natural fiber, mixed fabric is an appropriate material for policewomen's uniforms. third the feminine image of policewomen was considered; therefore, masculine image, which is rigid and strong, was avoided and the image was expressed in a serene and beautiful way. Also slim line was added to the current uniforms to emphasize feminine beauty. The conclusion of this study is that police officers in the 21st century want to be seen as the citizens cane and benevolent volunteers that live together with the citizens, not as suppressive and powerful people.

Background: We analyzed the results of surgical reduction and fixation of ribs under thoracic epidural anesthesia and analgesia (TEA) in patients who had no more than 3 consecutive rib fractures with severe displacement to examine the clinical usefulness of this method. Materials and Methods: From May 2008 to March 2010, 35 patients underwent surgical reduction and fixation of ribs under TEA. We reviewed the indications for this technique, number of fixed ribs, combined surgical procedures for thoracic trauma, intraoperative cardiopulmonary events, postoperative complications, reestablishment of enteral nutrition, and ambulation. Results: The indications of TEA were malunion or nonunion of fractured ribs in 29 (82.9%; first operation) and incompletely ribs under previous general anesthesia in 6 (17.1%; second operation). The average number of fixed ribs per patient was 1.7 (range: 1~3). As a combined operation for thoracic trauma, 17 patients (48.6%) underwent removal of intrathoracic hematomas, and we performed repair of lung parenchyma (2), wedge resection of lung (1) for accompanying lung injury and pericardiostomy (1) for delayed hemopericardium. No patient had any intraoperative cardiopulmonary event nor did any need to switch to general anesthesia. We experienced 3 postoperative complications (8.6%): 2 extrapleural hematomas that spontaneously resolved without treatment and 1 wound infection treated with secondary closure of the wound. All patients reestablished oral feeding immediately after awakening and resumed walking ambulation the day after operation. Conclusion: Thoracic epidural anesthesia and analgesia (TEA) may positively affect cardiopulmonary function in the perioperative period. Moreover, this technique leads to an earlier return of gastrointestinal function and early ambulation without severe postoperative complications, resulting in a shortened hospital stay and lowered costs.

This study is to suggest the tasks of Christian Education for developing empathic emotional ability of women in AI era through examining the meaning of empathic sensibilization and the examples of women overcoming the hardships of their times and bringing about change. Empathic sensibility is becoming a issue and empathy is emphasized in AI era. Because empathy is becoming a big support in overcoming hardships, and empathic emotion is showing human dignity, equality, service, devotion and consideration and so is forming a global community living together. And on investigation of the examples of women overcoming the hardships of their times, I found that as a woman with a sense and thought, as a historical human being, not as a gender, the tasks of Christian Education for developing empathic sensibility ability of women in AI era will be effort to be yourself, theological identity reestablishment of women and developing insight to read the times.
