  • Background: Major pulmonary resection after neoadjuvant concurrent chemoradiation therapy (nCCRT) is associated with a substantial risk of postoperative complications. This study investigated postoperative complications and associated risk factors to facilitate the selection of suitable surgical candidates following nCCRT in stage IIIA-N2 non-small cell lung cancer (NSCLC). Methods: We conducted a retrospective analysis of patients diagnosed with clinical stage IIIA-N2 NSCLC who underwent surgical resection following nCCRT between 1997 and 2013. Perioperative characteristics and clinical factors associated with morbidity and mortality were analyzed using univariable and multivariable logistic regression. Results: A total of 574 patients underwent major lung resection after induction CCRT. Thirty-day and 90-day postoperative mortality occurred in 8 patients (1.4%) and 41 patients (7.1%), respectively. Acute respiratory distress syndrome (n=6, 4.5%) was the primary cause of in-hospital mortality. Morbidity occurred in 199 patients (34.7%). Multivariable analysis identified significant predictors of morbidity, including patient age exceeding 70 years (odds ratio [OR], 1.8; p=0.04), low body mass index (OR, 2.6; p=0.02), and pneumonectomy (OR, 1.8; p=0.03). Patient age over 70 years (OR, 1.8; p=0.02) and pneumonectomy (OR, 3.26; p<0.01) were independent predictors of mortality in the multivariable analysis. Conclusion: In conclusion, the surgical outcomes following nCCRT are less favorable for individuals aged over 70 years or those undergoing pneumonectomy. Special attention is warranted for these patients due to their heightened risks of respiratory complications. In high-risk patients, such as elderly patients with decreased lung function, alternative treatment options like definitive CCRT should be considered instead of surgical resection.

  • There are groundwater trouble by high-salinity yield inducing sea-water intrusion in Cheju Island. It is used groundwater-GIS(Well-lnfo) in the maintenance and management of groundwater in Cheju Island to grasp groundwater trouble area and cause of high-salinity yield. For 16 wells certain to yield high-salinity, we logged specific electrical conductivity(EC) and tried to get hold of freshwater and saltwater relationship. As result of distribution of $Cl^-$ by depth, it is showed up groundwater trouble by high-salinity yield in the east coastal area and the partly north coastal area. The reason of high-salinity groundwater yield are low-groundwater level by the structure of geology and low-hydraulic gradient etc. There is necessity for management to development and use of groundwater in the high-salinity area, special management area.

  • The purpose of this study was to provide the basic data necessary for establishing a vegetation management plan for the Yeongcheon River area by presenting a better understanding of the distribution and characteristics of naturalized plants through an investigation of the flora present in the Yeongcheon riverside, in Jinju, South Korea. Vascular plants were investigated for a total of 470 taxa, including 90 families, 282 genera, 425 species, one sub-species, 38 varieties, and six forms. Together, these accounted for 9.62% of the vascular plants (4,881 species) in Korea. Gramineae was the most abundant at 77 taxa (16.38%), followed by Cyperaceae at 56 taxa (11.91%), Leguminosae at 33 taxa (7.02%), Cyperaceae at 25 taxa (5.32%), and Rosaceae at 22 taxa (4.86%). Thirty species of indicator plants were surveyed and, among them, annual plants and hemicryptophytes accounted for a significantpercentage. Among ground plants, trees, shrubs, and sub-shrubs were surveyed to include 23 (4.89%), 17 (3.61%), and 14 taxa (2.97%), respectively. Furthermore, 36 aquatic plant taxa were found. Six rare plant taxa were surveyed including Penthorum chinense, Melothria japonica, Aristolochia contorta, Acorus calamus, Millettia japonica, and Magnolia kobus. Floristic special plants comprised 35 taxa,including 26 families, 34 genera, 34 species, and one variety. Plants endemic to Korea included six species. Naturalized plant species comprised 71 taxa, including 18 families, 53 genera, 68 species, and three varieties. The naturalization rate and urbanization index were 15.1% and 22.1%, respectively. Ecological disturbance species in Korea comprised nine taxa, including four families, eight genera, eight species, and one variety. These groups accounted for 64% of the ecological disturbance species in Korea. Ecological disturbance species in Korea tended to increase toward the downstream of Yeongcheon River. In particular, Ambrosia artemisiifolia and Sicyos angulatus, which cause human allergies and disrupt the habitats of plants and animals, must be removed artificially.

  • Background : In recent years, lung cancer has been one of most common cause of death in Korea. Despite many physician's high degree of pessimism about the gains made in treatment, progressive improvement in the survival of lung cancer by treatment has occurred, particulary in the early stages of the disease. However, a lot of patients refuse treatment or give up in the fight against the disease. This study was done to evaluate factors influencing the compliance to therapy and to lead in the establishment of special programs to enhance compliance in patients with lung cancer. Methods: The medical records of 903 patients, whose ECOG(Eastern Cooperative Oncology Group) performance status was 3 or less and whose medical record was relatively satisfactory, among 1141 patients diagnosed with lung cancer between January 1989 and December 1996 were reviewed retrospectively. Compliance was classified into three groups based on the degree of compliance with physicians practice guideline: (a) compliants; (b) patients who initially complied but gave up of themselves midway during the course of treatment; (c) noncompliants who refused the treatment. Results: The overall compliance rate was 63.9%, which was progressively increased from 57.3-61.3% in 1989 and 1990 to 64.2-67.5% in 1995 and 1996. Age, education level and occupation of patients bore statistically significant relationship with the compliance but sex, marital status and smoking history did not. The compliance was significantly higher in patients without symptoms than with, and was also significantly higher in patients with good performance status. The compliance was significantly high in patients with NSCLC(non-small cell lung cancer) compared to SCLC(small cell lung cancer), but after exclusion of stage I and II, among NSCLC, which had higher compliance to surgery there was no significant difference of compliance by histology. The compliance was significantly lower in advanced stage. Conclusion: To enhance the compliance, special care including education programs about therapy including complication and prognosis are necessary, especially for educationally and economically disadvantaged patients.

  • This paper aims at exploring the characteristics and meanings of religious freedom controversy surrounding religious education, with special reference to proselytism, in protestant mission school in recent Korea. Most of protestant mission schools have been providing students compulsory religion class and chapel service in the name of religious education. According to the school authorities, religious education should be provided for the realization of founding philosophy, and they say that mission school has the right to religious education. On the contrary, many non-christian students argue that their religious liberty is seriously violated by required religious education especially compulsory chapel worship. So serious conflicts broke between mission school authorities and students. Supreme Court decided that Soongsil University has the right to maintain compulsory chapel service, ruling that Daegwang High School should not maintain required chapel worship. It seems that Supreme Court gave different decisions to high school and university respectively, considering the differences between high school and university in application for admission to a school, students' critical consciousness, school's autonomous rights, etc. However, these precedents are being challenged by many peoples and groups. There are three agents which are involved in religious freedom controversy in mission school. The first are mission school authorities supported by religious groups, the second government supported by political parties, and the third mission school students guided by NGO. Among them protestant groups are playing the major role in making religious freedom problems in mission school. Protestant groups try to convert mission school students to protestantism by compulsory chapel service and religion class. Such a protestant proselytism becomes a cause of oppressing students' human rights and religious liberty. In this situation government has a responsibility to protect the students' rights to religious freedom. But government seldom impose sanctions on the protestant mission schools' compulsory programs. The reason why government does not restrict mission school's unlawful religious education is because protestant groups have strong influence in voting. Eventually civil movements organizations involved in religious freedom controversy for the sake of students's human rights. In conclusion, the assailment is protestant proselytism, the accessory is government, the victim is students in the religious education in mission school in recent Korea.

  • This study was conducted to compare the perceptions of the park use status, importance, and satisfaction of users in the first implemented and completed Uijeongbu Jikdong Neighborhood Park among the private park special projects carried out as a countermeasure for long-term non-execution of urban parks. To this end, in the initiated project, apartment residents and non-residents were classified according to the promotion plan, and a questionnaire research on importance and satisfaction was conducted to analyze the park use status and IPA(importance-performance analysis). First, as a result of the analysis of the current situation in terms of locational characteristics that occur during the promotion of special projects for private parks, unlike the mountainous areas, the targeted site was close to flat land, indicating that users' satisfaction with the landscape was high. Second, the access of the apartment residents in the initiated project site was easy. Thus, the use rate of residents was relatively higher than that of the non-residents. Third, differences in perception by item were identified through the analysis of IPA and the establishment of strategies. In quadrant I, among the facilities and services, installing restrooms was the priority for residents, and parking facilities and rest facilities were the priority than installing restrooms for non-residents. In quadrant II, overall scores for residents and non-residents were similar, but the distance to the park was in quadrant III due to the low level of satisfaction among non-residents. In this study, the difference in perception between residents and non-residents may cause problems in access and facilities in managing the park in the future. Therefore, it would be necessary to find a way to improve it by establishing a management strategy that takes into account the difference in the perception of residents after construction. In addition, through the results of this study, it was judged that the purpose of park development, the selection of types of parks, and the selection of plans and management indicators for each kind would be significant in the promotion of initiated projects in the planning of park development.

  • Recently, the Korean Supreme Court released two important decisions concerning damages for the pain and suffering from Aircraft noise. The local people who are living near the Air Force practice site at Maehyang-ri and the Kimpo International Airport brought lawsuits against the Korean government requesting damages for their financial loss from the severe noise and the damages for their pain and suffering. Plaintiffs alleged that they suffered physical malfunctions, extreme disturbances and the reduction of property values from the extreme noises which were daily repeated. District Court of Seoul Province did not allow plaintiffs all but the damages for pain and suffering. Plaintiffs could not prove the causation between their financial loss and the noise. The Supreme Court confirmed the lower court's decision. Article V of the National Compensation Act (analogous to the Federal Tort Claims Act of the USA) reads, "the government shall be liable for any loss caused by the defect on establishment or maintenance of public facilities." In the two cases, the major issue was whether the government's establishment or maintenance of Air Force practice site and the airport was defective because they caused serious noise to surrounding neighbors. Previously, the Supreme Court interpreted the clause "defect on establishment or maintenance of public facilities" as failure of duty to provide safety measures to the degree generally required to ordinary manager. However the Court at this time interpreted differently that the defect could be found if the facility caused to any person loss to the degree intolerable. In the two cases the Court confirmed the lower court's finding that noise level at the site was severe enough to be intolerable. This standard is based on the severity of the loss rather than the failure of duty. It became easier for plaintiffs to prove the cause of action under this interpretation. The consequence of the ruling of these two cases is 'rush to the courtroom' by the local people at similar situations. The ruling of these two cases was not appropriate both in theory and in consequence. The Korean tort system is basically based on the theory of negligence. Strict liability is exceptional only when there is special legislation. The Court created strict liability rule by interpreting the Art. V of the National Compensation Act. This is against the proper role of the court. The result of the cases is also dismal. The government was already sued by a number of local people for damages. Especially the Department of Defense which is operating many airports nationwide has financial hardship, which will cause downsizing military practice by the Air Force in the long run, This is no good to anyone. Tens of millions of dollars which might be used for compensation might be better used to prevent further noise problem surrounding airports.

  • Background : Murine typhus is a flea-borne, worldwide Rickettsial disease caused by Rickettsia typhi. Its symptoms are typically mild but sometimes can be fatal. The major clinical features include fever, rash, and headache. Recently, we experienced 6 cases of ARDS associated with a Rickettsia typhi infection. This study was aimed to analyze the attributing factors for fatal murine typhus and to review the characteristics of the patients who showed acute respiratory distress syndrome as the initial presentation. Methods : The medical records of 15 patients diagnosed as murine typhus were reviewed. The diagnosis was made by single titers of 1:512 or higher, or a 4-fold rise with compatible clinical features. Acute Respiratory Distress Syndrome (ARDS) was defined according to the American-European Consensus Conference. The Characteristics between the ARDS group and the non-ARDS group of murine typhus were compared. Results : Six patients developed ARDS as their initial presentation. Two of them were women and three of them had lived urban area. None of Them a showed skin rash. One of them expired during treatment. The time lapse until the commencement of the specific treatment, the lower serum albumin level, the higher serum total bilirubin level, the higher APACHE III score and the higher MOD score were significantly associated with the ARDS group compared to the non-ARDS group. Conclusion : Murine typhus should be considered as one of the etiologies for the ARDS of unknown cause, particularly in an endemic regions. ARDS caused by Murine typhus generally has a good prognosis.

  • The purpose of this study is to propose guidance for wall renewal that is appropriate for an ancient city wall through application of advanced research and theories in wall design. It is a streetscape improvement project which forms part of the "Ancient City Image Finding Project". Study methods consist of advanced research classification, wall design theory contemplation, and analysis of the significance of designated ancient city areas and the "Ancient City Image Finding Project" status. Based on these methods, case study candidates were selected, case status and problems were identified, and improvement proposals were analyzed by comparing various features. Advanced wall research was classified into six categories including analysis of wall characteristics; wall design principle applications; wall structure, color, shape, and application; modern reinterpretation; palace walls; and house, temple, and village walls. The wall is an element of the streetscape improvement component of the "Ancient City Image Finding Project", with the characteristic of providing preceding experience in visual and cognitive awareness than interior structure. Case candidates for ancient city wall improvement are based on the composition distribution of the special conservation district in each ancient city as well as the conservation promotion district. Ultimately, the surrounding village of Gongju-si Geumseong-Dong Songsanri-gil, adjacent to the Royal Tomb of King Muryeong, was selected as the candidate. The "Ancient City Image Finding Project" of the surrounding village of Gongju-si Geumseong-Dong Songsanri-gil began with new Hanok construction. However, wall maintenance did not begin concurrently with that new Hanok construction. Support and maintenance took place afterwards as an exterior maintenance project for roadside structures. If the Hanok and wall were evaluated and constructed at the same time, the wall would have been built in unison with the size and design of the Hanok. The layout of the main building and wall of the Hanok is deemed to be a structure that is closed tightly because of its spatial proximity and tall height. Songsan-ri-gil's wall design should create a calm, subtle, and peaceful atmosphere with shapes, colors, and materials that express ancient city characteristics, but it is in an awkward position due to its sharpness and narrowness. The cause of the problem at Gongju-si Geumseong-dong Songsanri-gil, the case candidate, is that it is lacking significantly in terms of the aesthetic factors that traditional walls should possess. First, aesthetic consciousness seems to have disappeared during the selection and application process of the wall's natural materials. Second, the level of completion in design and harmony is absent. Maintenance guidance after analyzing the cause of problems in ancient city wall maintenance at Gongju-si Geumseong-dong Songsanri-gil, the subject area of research, is as follows: First, the Hanok design and layout of the wall and main gate should be reviewed simultaneously. Second, the one-sided use of natural stone wall in the Hanok wall design should be reexamined. Third, a permanent system to coordinate the opinions of citizens and experts during the planning and design phases should be employed. Fourth and finally, the Hanok's individuality shall be collectivized and its value as a cultural asset representing the identity of the community shall be increased.

  • Iron-making industries of the country, regardless of age has been the focus. This makes the iron production technology and production techniques that result in increased economic activity and because of the central charge. Therefore, the social development of ancient iron-making technology is based on phase-sensitive. Modern steel making up the monopoly of the country's target under the strict control of production, distribution was. It is essential to produce iron weapons was a threat is because you can keep the throne in the hands of the forces that can cause side effects when I went was to block. This study created a rail Cholbi(iron monument) and the regional distribution pattern of the production, construction background, looked on. Cholbi(iron monument) for the production and recording "the Annals of the Joseon Dynasty" often appear in history books and many academic interests, but was off target. Compared to a stone monument that was not generally as well as the Japanese colonial period and over the course of modernization destroyed, damaged a lot of cases the cause may be found in front. Cholbi(iron monument), except for the gravestones of the Joseon Dynasty monument erected in honor of virtue, as an example of content that dominated a packman business, founding of the school and confirmed that a few were built as a special purpose. Cholbi(iron monument) compared to the production technology or the cost of the monument's difficulty in financing follows. Therefore Cholbi(iron monument) the establishment of the Joseon Dynasty through the background of the economic situation and the local government can look. And iron technology began complaining about the object of history, economic conditions, with the change of season has been a change in people's consciousness tells you. Important data of ancient history as an epigraph that has been as important, the Middle Ages to modern times ranging from newly born to the time Cholbi(iron monument) in the development of the country's documentary subject to change should have been brought. Based on these discussions changes the identity of the hero monument and production inspector, review of production through the Joseon Dynasty period Cholbi (iron monument) contemplated the significance is reflected in production.
