Background: Lung cancer is one of the commonest and most lethal cancers throughout the world. The majority of the patients present at advance stage and are not suitable for curative intent treatment. Even among patients with localized disease, there has been underutilization of curative treatment modalities. The aim of this study was to analyze the radical treatment utilization rates in patients with non small cell lung cancer (NSCLC) treated at our centre. Materials and Methods: We analyzed case records of 104 patients with a pathologically confirmed diagnosis of NSCLC having stage 1-3B disease who were treated at our centre over last 3 years, to assess the utilization of curative treatment modalities i.e. surgery or radical radiotherapy. Results: The median age of this cohort was 58 years. Out of 104 patients only 33 (31.7%) received curative intent treatment, 14 undergoing curative resection and 19 receiving radical doses of radiotherapy. The baseline characteristics of both the groups (with or without radical treatment) were not different. Major factors associated with underutilization with curative treatment were progressive disease or loss of follow up after chemotherapy and inappropriate use of TKI and/or palliative radiotherapy in patients with stage 1-3B disease. Patients who did not receive radical treatment had inferior PFS and OS than those who received radical treatment. Conclusions: In our practice we observed gross underutilization of curative intent treatment modalities in patients with NSCLCs which is associated with inferior survival.

Purpose: The purpose of this study was to explore the chronic patients' preferences for care near the end of life. Methods: This is a descriptive survey research, with subjects of 161 outpatients with hypertension, diabetes mellitus or chronic renal failure. Results: The majority of the subjects do not want meaningless life sustaining treatment and they report thinking positively about family or health care professional to participate in their end of life decision making process. Subjects reported preferring adequate pain management and spiritual support at the end of life. In regard to advance directives (ADs), those subjects with chronic disease report thinking positively about the necessity of ADs and its institutionalization. However, the subjects report not having the detailed information on the proper time and method of writing their ADs. Conclusion: Based on these results, educational programs on end of life decision making for chronic patients need to be developed. Also, the nurse should try to reflect the opinion of chronic patients as much as possible when make an end-of-life decision.

In the midfacial fracture, the orbital region presents many additional complication unique to the orbit. Among them are ectropion, entropion, lid ptosis, injury to the lacrimal apparatus, diplopia or the late development of enophthalmos. The residual problem confronting the surgen is usually enophthalmos or diplopia. Enophthalmos becomes cosmetically obvious at 3mm and if more severe it can interfere with vision from obstruction by the orbital rim. In this clinical situation, many patients prefer the simpler intraorbital volume expansion to the more complex orbital osteotomy. In general, except in mild cases of enophthalmos, the procedure of choice is osteotomy and repositioning for zygoma fracture and volume augmentation for blow-out fracture. Late treatment is performed by volume augmentation based on the CT findings behind the axis of the globe. Inferiorly placed grafts elevate the globe, posterior superior grafts move the globe anterior and medially positioned grafts push the globe laterally. In this two cases, the patients who has stable orbitozygomatic rim, the use of calvarial bone grafts more than 3 areas around intraorbital content, we corrected late enophthalmos combined with diplopia. As result, the first patient had 2mm advance in exophthalmometric check with improvement of the diplopia gradually. The second patient had 1.5mm advance with correction of vertical ocular dystopia and cosmetically good results respectively.

By classifying temporary denture production for surgical guides, digital guide-based surgery, and final prosthesis production, the problems of each process were assessed in advance and the factors that could be improved were confirmed in this study. The manufacturing process of fusion dental prosthesis uses virtual programs and computed tomography images to manufacture devices using the latest technologies of computer-aided design/computer-aided manufacturing and three-dimensional printing, which enables implants to be placed in the desired location in advance. Moreover, implant placement is not dependent on the skill and condition of the dentist, and because it uses a computer system, it can always be performed at a constant and optimal position. This can reduce the remanufacturing rate compared with the general method, shorten the treatment period, and eliminate patient discomfort. Unlike the traditional method of using impression materials and plaster models, digital fusion dental prostheses would be evaluated as a technology for producing prosthesis through professional design technology and communication.

Activation Plan for International Health Care through the Resolution of Medical Disputes with Foreign Patients. The field of international health care is currently being expanded and developed into the new industrial field of medical tourism through the convergence of medicine - a public sector - and tourism - a private sector. This study examines problems with medical law regarding the prevention of medical disputes that may occur when attracting foreign patients and the resolution of these disputes. It also introduces the current most ideal resolution plan for medical disputes. Advanced measures for the prevention of medical disputes with foreign patients are as follows: First, when conducting international health care, the obligation to explain a medical treatment should be applied at higher standards for foreign patients. Second, all medical treatment procedures, including appointments, treatments, discharge, post-operation consultations, and follow-up treatments of foreign patients should be charted and recorded. A checklist regarding precautions for each procedure along with a response manual for problems should also be established. These regulations can prevent unexpected conflicts in advance when medical disputes occur. If a medical dispute with a foreign patient occurs despite thorough advance prevention, it can be resolved through reconciliation, mediation, and arbitration. The government and the medical field along with its related industries and authorities should put their efforts into developing these priori/posteriori measures for the activation of international medical health care. The laws and technological/human capabilities in medicine should also be improved in order to activate international medical health care.

Microcystin, stable compounds with circular heptapeptides, is presented inside cyanobacterial cell. So far, over 30 types have been known to exist and microcystin-LR, RR among them are the most potent toxin compound. By this reason, a strong oxidant, ozone was used in this study to remove the microcystins produced by cyanobacteria. Removal efficiency of microcystin at M water treatment plant was also evaluated. Microcystin concentration was determined by protein phosphatase inhibition assay. The results showed that dissolved microcystin in raw water detected in the range of 0.011-0.028 ㎍ Microcystin-RR equivalent/l. Above 98% of microcystin was removed through overall treatment system. Therefore, the water treatability of M treatment plant seemed to be excellent. Removal efficiency of microcystin according to unit process varied as characteristics of raw water such as DOC, UV/sub 254/ and turbidity. Removal efficiency of microcystin by ozonation was investigated in laboratory according to contact time and ozone dose. Dissolved microcystin was increased by twice fold according to ozone contact time, but increased by fifth fold according to ozone dose. So, changing of ozone dose more affected microcystin release than changing of ozone contact time. Behavior of microcystin by ozonation was similar to that of DOC, and residual ozone concentration gave influence to removal ratio of microcystin. In conclusion, single ozone treatment wasn't effective on microcystin removal in case of water containing a lot of cells. Therefore, it's more effective to use ozonation process after the removal of cyanobacterial cells in advance.

A recent High Court's decision regarding the withdrawal of life supporting medical treatment (artificial ventilator) from an elderly female patient in the terminal stage has opened up a new era of the "euthanasia dispute" in Korea. With this decision, the legitimate withdrawal of life supporting treatment became possible under certain conditions and the Korean Medical Association is working toward the establishment of practical guidelines for the terminal-stage patients. However, there are still very few debates on the cases of pediatric patients in the terminal stage or suffering from fatal diseases. For pediatric patients, the core principle of autonomy and following procedure of "advance directives" are hardly kept due to the immaturity of the patients themselves. Decisions for their lives usually are in the hands of the parents, which may often bring out tragic disputes around "child abuse", especially in Korea where parents have exclusive control of the destiny of their children. Some developed countries such as the U.S.A., the U.K. and Canada have already established guidelines or a legal framework for ensuring the rights of the healthcare system regarding children suffering from severe illness, permitting the withdrawal of Life supporting medical treatment (LSMT) in very specific conditions when the quality of life of the children is severely threatened. For the protection of the welfare and interest of the children, we should discuss this issue and develop guidelines for the daily practice of pediatricians.

In this paper, we analyze the current phenomenon of child abuse crimes based on the information gathered by the National Child Protection Agency. The purpose of this paper is to diagnose the seriousness of child abuse by biological parents based on the analyzed information and propose measures against it. Comprehensive and integrated measures are needed for child abuse committed by biological parents due to abuse concealment, continuity of damage, and inactive national intervention by considering punishment on attackers through national intervention, fundamental in-depth psychological counseling, therapeutic care, promoting recovery of victims, and ultimately continuous and regular management and monitoring as a long-terms measure. To do so, developing customized and individual educational programs and make them obligations can be first presented to identify child abuse in advance and build up preventive systems based on the principle of family preservation. In addition, problems should be addressed at a fundamental level by performing various and active therapeutic treatments such as psychological treatment, mental treatment, or drug treatment gradually and through phases for biological parents who commit child abuse and contributing to recovering the relationship. Furthermore, proper protection and treatment service should be provided to children victimized by abuse by extending professional children care facilities and adopting the professional family commission system as measures by separating family.

The introduction of osseointegrated dental implants in dentistry brought about a new era in everyday dental practice. For the past 50 years, prosthetic restoration with implant-supported prosthesis has developed into a viable and predictable treatment option. Alongside the increasing use of dental implants is the occurrence of many complications during implant placement (surgery), in the mechanical or prosthetic problem, and in the biological aspect. In particular, abutment or screw fracture as one of the mechanical complications can put the dentist in a tight spot in a clinical situation. It is hard to remove the fractured abutment and screw to restore it properly. Therefore, it is very important that clinicians consider possible complications in advance and make an appropriate treatment plan. We discuss cases of abutment fracture and mechanical/prosthetic complications together with the causes and solutions.
