Purpose: The purpose of the study was to develop a feasible form of a Korean version of advance directives (K-AD). Methods: Sixteen adults participated in this study: 10 aged 20~50 years and nine aged 65 years or older. Using a draft version of the K-AD, cognitive interview was conducted on the participants to establish a culturally acceptable form of advance directives whose directions can be understood and responded accordingly by the general population. Results: Cognitive interviews revealed areas of concerns for the draft version of K-AD: lack of instructions or clarity for technical and medical terms, context complexity and inadequate response categories. The draft version was revised by rewording, offering examples and rearranging the context. Editorial style was added with appropriate uses of bold fonts, bullet-points and underlines to facilitate interviewees' cognitive responses. Conclusion: Study results feasibility of the revised version of the K-AD. Further study should be performed with a larger number of participants to develop a K-AD with an acceptable level of reliability and validity.

Land suitability assessments for agricultural crop production determine the suitability of an area in terms of crop yields. We employed the maximum limiting characteristic method (MLCM) and an analytic hierarchy process (AHP) to assess land suitability for Pears (Pyrus) in all Korean provinces (Dos). In general, suitability grades according to the MLCM were much lower than those according to the AHP. The MLCM determined that suitable areas (S1, S2, and S3) exist on 19.55% of the land, whereas 99.08% of the land was classified as suitable by the AHP. Based on information on pear farms in each Korean province in 5 years (1982, 1987, 1992, 1997, 2002, and 2007), the proportion of suitable land area according to the MLCM in each province as compared to all suitable areas was closer to the proportion of areas covered by pear farms in the 5 years in each province and also to the proportion of pear farm areas in 2007 in each province. Based on the assumption that if a province has more suitable areas for pears, more pears will be cultivated in that province, the results of the MLCM can be regarded as more accurate than those of the AHP.

Purpose: To investigate the treatment results' and patterns of failure according to the pathologic type of the parotid malignancy who were treated with radical sugery and postoperative radiation therapy. Materials and Methods: Fifty-two patients with various type of the parotid malignancy, who were treated with combined radical surgery and post-operative irradiation at Yonsei Cancer Center, between 1981 and 1995, were retrospectively reviewed after completion treatment, all but one patients were follow up with the median follow up period of 49 months. Results: We found that pathologically confirmed neck node metastasis rate was 28.8% all case and level II was most common site. Overall failure rate was 26.9%, local recurrence rate was 13.5%, node failure rate was 7.7%, and distant failure rate was 5.8%. Five-year disease free survival rate was 70.9%, and overall survival rate was 73.8%. Recurrence rate was low in adenoid cystic carcinoma and acinic cell carcinoma. However distant metastasis was very high in undifferentiated carcinoma. Local recurrence was main pattern of failure in mucoepidermoid carcinoma and nodal failure was frequently observed in adenocarcinoma. Conclusion: Individualized treatment plan may be required to improve a treatment outcome by pathologic subtype of the parotid malignancy.

This research investigated the facts about the place and date of praying for the engraving of the first edition of Tripitaka Koreana. Major findings are as follows: 1) The very first idea of engraving the first edition of Tripitaka Koreana was evidenced in the record of 'The beginning of Tripitaka Koreana' from 'Daejanggakpan Gunsin Gigomun' written by YiGyuBo. 2) After comparing the contents of 'Daejanggakpan Gunsin Gigomun' with the record of the third volume of 'Goryeosa Jeolyo' dated February 13, 1011, this researcher confirmed that 'Daejanggakpan Gunsin Gigomun' also recorded this historical fact. 3) In the third volume of 'Goryeosa Jeolyo' dated February 13th, 1011, it is documented that a ritual was held to pray to the gods of heaven and earth for expelling the Kitan from the country. Further, the document states that this particular ritual consisted of a ceremony of lanterns held at the temporary palace in Cheongju on February 15th, to report to the gods on 'the engraving of the first edition of Tripitaka Koreana' 4) Therefore, it is verified that the date of praying for the engraving of the first edition of Tripitaka Koreana was February 15th of the lunar calendar, 1011(the second year of King Hyunjong's reign), and the place was the temporary palace in Cheongju.
The walls of guard cells have many different specialized features. Guard cells are present in leaves of bryophytes, ferns and almost all of the vascular plants. Guard cells show considerable morphological diversities. It is understood that the stomata show two types in terms of morphological characterizations of guard cells. The first type is only found in a few monocots including Poaceae and Cyperaceae. In rice and corn, guard cells have the morphological characteristics of dumbbell shape. The morphological characteristics of dumbbell shape always have subsidiary cells. The other type is found in every dicots and many monocots and they are kidney-shaped guard cells. The plants of kidney-shaped guard cells rarely have subsidiary cells except Commelina communis L. Therefore, it could be concluded that two types of the morphological characteristics of guard cells cannot divide according to monocots or dicots. Every plants in which stomatal characteristic features were all different, most of them belong to kidney-shaped guard cells. However in case of Sedum sarmentosum, guard cells were shown to be long and narrow lips type. In Tradescantia virginiana, the shape of guard cells could be called perfectly to half-moon type. Therefore, it could be concluded that kidney-shaped types are all different in some way, but dumbbell-shaped types are almost constant.
This study examines why follow-up investigative programs about the sinking of the Cheonan Patrol Combat Corvette(ROKS Cheonan) have not been produced, despite much speculation surrounding the cause of the sinking since November 2010, when KBS investigative program, In-Depth 60 Minutes which had covered the incident was aired. We have uncovered four reasons through a series of in-depth interviews with producers and reporters, as follows. First, Korean military authorities monopolized relevant information, while the producers could not prove or confirm the validity of the findings of the JIG(Joint Civilian-Military Investigation Group)'s report because the facts had been revealed partially and selectively by the authorities and the press' scientific investigation were rejected by the authorities. Second, the crew of In-Depth 60 Minutes was subjected to severe disciplinary action by the Korea Communications Commission. This caused a chilling effect, - it broke the producers' resolve to further explore the reason behind the sinking. Furthermore, the screening of the investigative documentary, Project Cheonan Ship was cancelled without prior notice, presumably by the power of the State and markets. Third, the reorganization and shake-up of personnel by broadcasting stations' presidents appointed by the power of the State crushed the spirit of PD Journalism. Finally, the "red purge" factions stigmatized by the political or military, or the mainstream press, caused the producers or broadcasters to engage in self-censorship. The idea has been used in Korea as a smoke screen to deflect public attention. Nevertheless, the producers hope to shed light on the Cheonan sinking incident and to prove reasonable doubts by pursuing follow-up investigations.
The purpose of this study is to investigate the historical progress about Teukgongmusul as bodyguard martial arts focused on security service history through the meaning of its development and expansion. This study used secret materials from presidential security service, military service headquarters and special merit unit in Korea, and also used interview materials by oral history. For the above tasks, the conclusions of this study are as follows: Firstly, consideration about the background and circumstances of Teukgongmusul when it was developed in 1970s. No.606 special merit unit's soldiers who worked in presidential security service in Korea organized Teukgongmusul. Secondly, consideration about the meanings of Teukgongmusul presented through its development and expansion process. Teukgongmusul was bodyguards' martial arts which was based on Army's martial arts in 1970s. For this reason, Teukgongmusul now has the perception as Bodyguard Martial Arts. Thirdly, consideration about the expansion process of Teukgongmusul when it was adopted in Army and presidential security service in Korea. In 1970s special merit unit was included in presidential security service in Korea where Teukgongmusul was developed. Afterward Teukgongmusul was expanded in two different ways which were Army and presidential security service in Korea. In Army Teukgongmusul was expanded by no.5 special merit brigade and was expanded by Hapkido master who was worked as martial arts instructor for presidential security service in Korea. Fourthly, the historical progress of Teukgongmusul as bodyguard martial art was influenced by the political situation.
Purpose: Unresectable rectal cancer has a grave prognosis. regardless of the therapy used and median survival is less than 1 rear. Also, it is reported by many authors that $50-80\%$ of unresectable lesions were rendered resectable by radiation therapy and the median survival time for the completely resected patients were better than that of the unresected patients. So we analyzed retrospectively our data for the better treatment outcome in these patients. Materials and MEthods:From 1980 to 1992, 45 patients with initially unresectable tumors in the rectum were treated with radiation therapy with/without surgery in Department of Radiation Oncology, Yonsei Cancer Center 10 MV radiation and multiple field technique (box or AP/PA) were used. The total dose was 28-70 Gy and median dose was 48 Gy. We evaluated the lesion status at 45-50 Gy for operability. If the lesions appeared to be resectable, the Patients were operated on 4-6 weeks after radiation therapy. But if the lesions were still fixed, the radiation dose was increased to 60-65 Gy. Results: For all patients, the 2-year actuarial survival was $13.3\%$ and median survival was 9.5 months. Of 6 patients who had received less than 45 Gy, only $17\%$ of patients responded, but in the patients who had received more than 45 Gy, $60\%$ of response rate was achieved Six of the 24 patients$(25\%)$ underwent surgical resections following RT. For patients undergoing curative resection. the two-rear survival was $50\%,$ but that of the patients without resection was $9.5\%$ (p<0.01). Survival of patients with complete response following RT was $50\%$ at 2 years. Survival of patients with partial response, stable disease and progressive disease after RT was $13.4\%,\;15.4\%,\;0\%$ respectively (P<0.05). Conclision: Our data suffests that the efforts which can increase the response rate and aggressive surgical approach are needed to achieve the better local control and survival in unresectable rectal cancers.
Backgrounds : The purpose of this study was to identify drugs that can enhance radioresponse of murine fepatocarcinorna. Methods : CSH/HeJ mice bearing 8 mm tumors of murine fepatocarcinorna, HCa-1, were treated with 25 Gy radiation and one of the following drugs: 5-Fu, 150 mghg; adriamycin, 8 mg/kg; cisplatin, 6 mg/kg; paclitaxel, 40 mg/kg; and gemcitabine, 50 mg/kg. Tumor response to the treatment was determined by tumor growth delay assay and by enhancement factor. Apoptotic level was assessed in tissue sections. Expression of regulating molecules was analyzed by western blotting for p53, Bcl-2, Bax, Bcl-XL, Bcl-XS, and p21$^{WAF1/CIP1}$. Results :Among the drugs tested, only gemcitabine enhanced the antitumor effect of radiation, with enhancement factor of 1.6. Induction of apoptosis by a combination of gemcitabine and radiation was shown as only additive level. In analysis of radiation-induced expression of regulating molecules, the most significant change by combining gemcitabine was activation of p21$^{WAF1/CIP1}$ Conclusion :Gemcitabine is the first drug showing an enhancement of radioresponse in murine hepatocarcinoma, when combined with radiation. The key element of enhancement is thought to be p21$^{WAF1/CIP1}$.
This experimental research as media effect study explores the effect of the current documentary that deals with radioactive contamination widely spread by fukushima nuclear accident on political and social recognition of domestic audience. Proceeding studies about media effect dealt mainly with news contents of TV, newspaper and internet. However studies on the effect of current documentary as non news contents on audience that provide us with profound information by various subjects are very few. Especially it is difficult to find studies about disaster documentary dealing with radioactive contamination having much effect on global environment. Accordingly this research implemented experimental study to find out the effect of current documentary that deals with radioactive contamination by fukushima nuclear accident on political and social recognition of audience. This research found that subjects exposed to the current documentary considered outdated nuclear power plant more seriously, supporting the opposition party more positively, claiming shutdown of outdated nuclear power plant, and opposing additive construction of nuclear power plant than subjects not exposed to the current documentary.
