  • Background: Esophageal perforation is an uncommon problem, but it is associated with high mortality. We performed a retrospective review of patients with instrumental esophageal perforation to assess the outcome of current management techniques. Material and Method: We retrospectively analyzed all cases of instrumental esophageal perforation diagnosed at our hospital from January 1999 through to March 2005. The study group consisted of 12 patients (8 women and 4 men) with a mean age of 48.8 years (range, $21{\sim}83$ years). We reviewed the effects of the surgical or medical treatments in various conditions of patients, such as of various sites of perforation and time delayed after injury. Result: Perforations were due to diagnostic endoscopy (50.0%, 6/12), esophageal bougination for benign stricture (33.3%, 4/12), endoscopic port insertion (8.3%, 1/12), and tracheal intubation (8.3%, 1/12). The perforated sites were thoracic in 7 patients and cervical in 5. The treatment included resection and reconstruction (5 cases), incision and drainage (4 cases), medical treatment (2 cases), and closed thoracostomy drainage only (1 case). Post-operative complications of transient pneumonia and wound infection were developed in 1 patient respectively. Both occurred in two patients with diffuse mediastinal abscess formation. The overall mortality was 8.3% (1/12) in one old patient who was managed medically for cervical esophageal perforation. Conclusion: We concluded that surgical treatment for esophageal perforations was safe and effective whether diagnosed early or lately.

  • Objectives : This study aims to examine satisfaction of dental treatment and revisit and intention of recommendation to dental patients and to supply as a basic resource for dental management improvement. Methods : 645 dental patients to dental hospitals in G City were subjects of this study. 27 dental hospitals were randomly chosen per 5 or 6 in 5 Districts. The intention of the survey was explained to 645 patients and it was agreed to have questionnaire survey. Questionnaire survey was carried out for 2 weeks in April 2011. Total 593 were used for the analysis except for insufficient answer sheets. The analysis was executed by using SPSS 18.0 and the results are as follows. Results : 1. The highest figures are as follows: female was 53.29% in sex, 20-29 age group was 44.52%, graduates of university were 38.62%, students were 28.50%, monthly family income with 300-399 million won was 31.70%. As to the treatment, dental caries were highest with 46.21% followed by scaling with 40.81%. As to the number of visit, 39.80% were over 5 times, and as to the opportunity to use, 29.34% answered it because it is close to home. 2. As to satisfaction, male was 4.15, over 60years old was 4.58, self-employed was 4.33, friendship with dentist as opportunity to use was 4.37. And as to revisit intention, over 60 years old was 4.60, over postgraduate in education level was 4.38, self-employed was 4.43, over 5 times visit was 4.32, and fame as opportunity to use was 4.39 which were the highest. As to the intention of recommendation to others, female was 4.24, over 60 years old was 4.65, self-employed was 4.36, friendship with dentist as opportunity was 4.43 which were the highest and showed significant differences (p<0.05). 3. As to patient satisfaction, there were strong relevance between revisit intention and intention of recommendation with 0.769 and 0.744 respectively. And, as to revisit intention, it had significant relation with revisit intention with 0.791. 4. The explanatory power of the regression analysis on the factors affecting revisit intention was 61.20%. The revisit intention was high when the satisfaction of dental hospital was high (${\beta}$=0.767, p<0.001), the number of visit (${\beta}$=0.026, p<0.01), reason for a visit (${\beta}$=0.070, p<0.01), education level (${\beta}$=-0.063, p<0.05) and occupation (${\beta}$=0.078, p<0.05). 5. The explanatory power of the regression analysis on the factors affecting intention of recommendation was 59.9%. The intention was taken patients satisfaction(${\beta}$=0.601, p<0.001), dental hygienist's kindness (${\beta}$=0.218, p<0.001), female (${\beta}$=0.079, p<0.05), reason for a visit(${\beta}$=-0.059, p<0.05), dissatisfaction treat(${\beta}$=0.084, p<0.05), dentist's kindness (${\beta}$=-0.080, p<0.05), age (${\beta}$=0.054, p<0.05). Conclusions : To improve revisit rate of patients, the refurbishing hospital facility, treatment and kindness of dental hygienists and satisfaction of treatment must be improved. And it also needs to accept complaint from female patients in a positive manner, and understand and correct complaints actively from the perspective of patients.

  • Objective : The purpose of this study was to investigate the quality of life and it's related factors in caregivers of attention deficit hyperactivity disorder patients. Methods : The subjects were 38 attention deficit hyperactivity disorder patients' caregivers(mean age : $37.5{\pm}6.5$, 38 women). Patients were diagnosed with DSM-IV-TR ADHD criteria. Korean version of WHOQOL-BREF(World Health Organization Quality of Life assessment instrument Abbreviated Version) was used for assessment. Results : 1) No significant differences were found in the score of WHOQOL-BREF, overall QOL, physical health domain, psychological domain, social relationships domain and environmental domain between caregiver and control group. 2) The score of Activity of daily living facet$(3.0{\pm}0.7\;vs.\;3.6{\pm}0.7)(p=0.008)$ and self-esteem facet $(2.8{\pm}0.7\;vs.\;3.3{\pm}0.7)(p=0.049)$ were significantly decreased in caregivers of ADHD. 3) Total score of WHOQOL-BREF(r=0.437, p=0.007) and physical health domain(r=0.370, p=0.024) were correlated with caregiver's educational age. 4) In the psychological domain, the score of self-esteem facet(r=-0.337, p=0.039) and thinking, learning, memory & concentration facet(r=-.341, p=0.036) were decreased with caregiver's age. 5) The score of environmental domain were significantly increased with caregiver's educational age (r=0.482, p=0.003), but decreased with patient's age(r=0.328, p=0.044). Conclusion : Although the quality of life in caregivers of ADHD patient had not significantly decreased than control, the quality of lift were positively correlated with educational age of caregives, and negatively correlated with chronological age of caregivers and children. Above results suggest that physicians should consider integrated approaches for caregiver's subjective quality of life in the management of ADHD.

  • The purpose of this study was to evaluate the effects of secondary task such as sending text message (STM) and searching navigation (SN) using the variable indicating control of vehicle ((Medial-Lateral Coefficient of Variation, MLCV), (Anterior-Posterior Coefficient of Variation, APCV)) and motion signal (Jerk-Cost function, JC). Participants included 50s taxi drivers; 14 males and 14 females. Participants were instructed to keep a certain distance (30m) from the car ahead with constant speed (80km/hr or 100km/hr). Experiement consisted of driving alone for 1minute and driving with secondary task for 1minute. Both MLCV and APCV were significantly increased during Driving + Sending Text Message(STM) and Driving + Searching Navigation(SN) than Driving only. Also, JC was increased during Driving + STM and Driving + SN than Driving only. In this study, we found that even in the experts group who are taxi driver and have 25 years driving experience, the smoothness of motion is decreased and the control of vehicle is disturbed when they were performing secondary tasks like sending text message or searching navigation.

  • This research paper is to examine James Watt who led the 1st industrial revolution successfully. His great work was called monumental achievement in the human history of civilization. Here, we looked over the Watts' educational environment during his infant, juvenile, and adolescence period and also, his learning attitude about his own field through literature review. The basic infra of soft and hard wares for the industrial revolution through the process of R & D on new developing steam engine resulted from the very industrial revolution and its R & D environment were to be investigated. The useful information and knowledge from this process of the research are able to give an appropriate educational guidance to bring up the development of creativity in schooling systems. And also a lesson from the past could be used to provide the desirable direction for the 4th industrial revolution which is just begun to start now. The main results from this study are as follows; First, Watts' parents positively guided him onto the technology of manual field because they recognized their son was interested in technology field. The parents' attitude stimulated and guided his sons' self-development, had been equal to the aims of education. Second, Watt made a chance of making friendships with professors of Glasgow University. He spontaneously had done self-directed learning for getting knowledge and technology, and thus he became an expert of practical engineer and theorist. Third, the Lunar society, which was jumping over one's social position in their society of the 18th century through new thinking way, leading new ages had been very good R & D social infra for Watt to open and connect new advanced level of science and technology in his age. This society provided a study environment fields for their members to exchange their ideas of scientific curiosity and freely inquiry, technology informations. They had discussed and understood the issues to be occurred in their own fields and accumulated necessary knowledge for problem-solving, respectively. Such as this R & D system environment will be also considered in the modern research group. Fourth, the entrepreneur such as Boulton, who understand technology and grasp its value in future, is needed. The system of 'grue of management' will support the researcher with financial support, which is necessary in R & D. And the researcher like Watt who takes pleasure in technology itself and study eagerly in his field without financial problems, that is, 'grue of technical expert' is essential when leading to success in the industrial revolution.

  • This study examined the effects of work-family spillover on the organizational attachment of female managers. The 4th and 5th data sets of Korean Women Manager Panel Survey established by the Korean Women's Development Institute were merged and the 5th data set for female managers was analyzed. The findings reveal that work-family support relationship is an important factor for strengthening the organizational attachment on the part of female managers. For working women, organizational support and family support is the most significant driving force for retaining their career. Second, negative spillover from family to work rather than that from work to family had a stronger impact on the organizational attachment of female managers. This finding suggests that women are not free from their status in the family, and that conflict relationships originating from the family ha a stronger impact on women's organizational attachment than that generated from work. Third, the third stage model incorporates the interaction terms of work-family spillover and organizational culture. The results showed that the interaction effect alone remains. In particular, family-work positive spillover exerts positive (+) effects on the organizational attachment only if a rational organizational culture is in place. Work-family negative spillover, however, shows negative (-) effects under rational organizational culture. Family-work negative spillover combined with rational organizational culture reinforces the organizational attachment, but has negative (-) effects under traditional organizational culture. The implications might be that women may experience negative family to work spillover, which may weaken their organizational attachment and that a rational organizational culture can reverse the spillover effect and increase the organizational attachment of female managers. No interaction effect of organizational culture appears for work to family negative spillover. A differential effect by the direction of spillover requires further study. In addition, more study will be needed to develop a more integrative model with the relevant variables not included in this study and sub-group analyses will be needed to ascertain the differences within female managers.

  • Objectives : Middle aged women with depression often experience hot flush symptoms. It is still unclear about the association between depression and hot flush symptoms. Therefore, we investigated hormonal profile, functional somatic symptoms, coping styles and attitude for menopause between depressed women with hot flush and those without hot flush. Methods : This study included 33 depressed patients with hot flush symptoms and 33 depressed patients without hot flush symptoms. Hot flush was confirmed through prospective daily symptom ratings for a week. Subjects' coping styles were assessed by the stress coping checklist. Somatic symptoms were assessed by the Patient Health Questionnaire-15(PHQ-15). Sex hormonal levels were assayed by a radioimmunoassay. The Brief World Health Organization Quality of Life Assessment Instrument(WHOQOL-BREF) was used to evaluate quality of life. Results : In coping style, depressed women with hot flush symptoms used less 'problem-centered coping'($13.15{\pm}3.17$) and 'search for social support'($11.83{\pm}2.84$) than those without hot flush symptoms($15.17{\pm}3.1$, p=0.028 ; $14.25{\pm}3.22$, p=0.009 ; respectively). Depressed women with hot flush symptoms showed more negative attitude toward post-menopause, but its statistical significance was marginally insufficient(p=0.059). We did not find any group differences in sex hormonal levels and somatic complaints assessed by the PHQ-15. The score of social relationship domain of WHOQOL-BREF was significantly lower in subjects with hot flush symptoms($8.62{\pm}2.04$) than subjects without hot flush symptoms($9.71{\pm}1.65$ ; p=0.044). Conclusions : Among middle aged women with depression, the manifestation of hot flush symptoms was associated with coping styles and attitude for menopausal transition. Hot flush symptoms in depressed women negatively influence quality of life, so clinicians actively perform therapeutic approach in case of depressed patients with hot flush symptoms. In case of depressed patients who present hot flushes, cognitive behavior therapy or stress management might be an effective treatment option in company with antidepressants or hormonal treatment. Later, longitudinal study will be needed to evaluate risk factor, cause and effect associated with hot flush and depression.

  • Purpose : To raise awareness of the clinical importance of, and the need for proper management of acute focal bacterial nephritis(AFBN), we analyzed 22 AFBN patients and 22 other upper urinary tract infection patients by use of comparative studies. Methods : From January 2000 to May 2002, 22 AFBN patients aged from 1 month to 12 months were selected. As a control group, 22 UTI patients with no radiologic abnormalities were selected and matched by age and sex. Results : The incidence of AFBN was more common in boys than in girls. Since both groups had similar symptoms, it was difficult to diagnose AFBN by clinical presentations alone. ESR and CRP were significantly higher in AFBN patients. The most common causative organism was E. coli in both groups. On the sonographic findings, the most lesions were seen on the upper lobe of the kidney; more frequently, on left kidney. The lesions showed globular or wedge-shaped increased echogenecity. $^{99m}Tc-DMSA$ scan showed the complete coincidence of the location, size and shape in all cases compared to the findings of renal sonography. Conclusion : The roles of renal sonography and DMSA scan were very important, and ultrasonography was an excellent initial tool in diagnosing AFBN. Since the degree of infection in AFBN is more severe than other urinary tract infections and evollution into a renal abscess is possible, early diagnosis and appropriate antibiotics therapy is essential.

  • In this paper, we propose a novel sharing method ordering the events occurring between users collaborated with the common telecomputing environment. We realize the sharing method with multimedia data to improve the coworking effect using teleprocessing network. This sharing method advances the efficiency of communicating projects such as remote education, tele-conference, and co-authoring of multimedia contents by offering conveniences of presentation, group authoring, common management, and transient event productions of the users. As for the conventional sharing white board system, all the multimedia contents segments should be authored by the exclusive program, and we cannot use any existing contents or program. Moreover we suffer from the problem that ordering error occurs in the teleprocessing operation because we do not have any line-up technology for the input ordering of commands. Therefore we develop a method of retrieving input and output events from the windows system and the message hooking technology which transmits between programs in the operating system In addition, we realize the allocation technology of the processing results for all sharing users of the distributed computing environment without any error. Our sharing technology should contribute to improve the face-to-face coworking efficiency for multimedia contents authoring, common blackboard system in the area of remote educations, and presentation display in visual conference.

  • In this study, six historical parks in Seoul is analyzed. Based on the analysis, the representative values of the historical parks in Seoul draw three criteria such as historicity, educational attributes, and sociality, and also the type of historic and cultural resources, spatial functions and arrangements, circulation and accessibility, and the type and usage of introduced facilities. Consequently the current status and improvement plan is suggested as follows. First, cultural assets oriented historical parks such as Sayuksin Bongeun and Seonnongdan historical Park focus on the management based on the preservation of historic and cultural resources. Non designated cultural heritages oriented historic parks such as Shingye Yanghwajin Itaewon-bugundang historic park should focus on the usages the symbolize and commemorate historic and cultural resources. Second, Careful attitudes on the historicity of the park are needed in the mixed type of historic and cultural resources that determine the identity such as Yanghwajin Itaewon-bugundang historic park. Third, the rate of facilities in Bongeun and Shingye historical park is increased due to the renovation of religion facilities, rather than the neighborhood parks. The autonomy of regulations that does not have the limits of the area of park facilities weaken the publicity of the historical parks. Fourth, Shingye historical park suggest changing its name into Danggogae martyrs' shrine historical park. because its historic and cultural resources are included as the historic park is named. Fifth, the current problems such as numerous uncontrolled entrances, mixed uses in circulation, and accessible failure due to the closure are recognized. Therefore, the entrances and circulations should be articulated clearly in order to increase opportunities of experience for visitors in the historic and cultural resources, and also neighborhood facility should be suitably divided. Sixth, the park facilities in the neighborhood parks are introduced equally in Seoul historical parks. The uses and arrangements that considered the circumstance of the historical parks should be determined in the cultural facilities such as outdoor music hall and sporting facilities. Seventh, historic facilities that named historic hall, culture hall, memorial hall, and promotion hall in the historic parks are utilized for convenience and religion facilities. Institutional framework should be examined to keep publicity in the historic parks by spatial privatization of the specific group.
