In this study, the implications for landscape architecture in the restoration Project of Cheonggyecheon will be shown through the analysis of factors for landscape architect scheme modification. The method of study consists of theoretical study, analysis of the plan and design of landscape architecture of the restoration project of Cheonggyecheon, and deduction of implications thereof. The controversial feints included the many difficulties in realizing the productive design of landscape architecture due to the selective collecting of public opinion and the problems of settling the complications, the design limit of the turnkey and MA systems, the lack of hydraulic knowledge and technology and the shortage of vegetation monitoring data and experimental materials. The alternative proposals are as follows: 1) there should be agreement between the government organization and the civil group, 2) in the turnkey bidding for the river restoration projects, the river restoration design based on the volume divided into some parts should be reconsidered in order to maintain consistency in the total design, 3) in order to maintain consistency in the planning policies, MA designs should also be introduced and applied from the first stage of the project through its completion, and 4) data such as the safe water level in case of flooding for the facilities and the vegetation and data in connection with the ecological restoration of river should be accumulated. If these controversies are not settled effectively, the river restoration project will be delayed due to complications with the citizens and wasted time and effort will result from the frequent design changes. In addition, landscape architecture in this kind of restoration project is bound to decrease in the future due to frequent changes in the hydraulic-centered design.

An embankment raising project on 113 agricultural reservoirs in Korea was implemented in 2009 to increase water supply capacity for agricultural water and instream uses. This study evaluated the future water supply capacity of the Imgo reservoir at which the agricultural reservoir embankment raising project was completed, considering climate change scenarios. The height of the embankment of the reservoir was increased by 4.5 m, thereby increasing its total storage from 1,657.0 thousand to 3,179.5 thousand cubic meters. To simulate the reservoir water storage with respect to climate changes, two climate change scenarios, namely, RCP 4.5 and RCP 8.5 (in which greenhouse gas reduction policy was executed and not executed, respectively) were applied with bias correction for reflecting the climate characteristics of the target basin. The analysis result of the agricultural water supply capacity in the future, after the agricultural reservoir embankment raising project is implemented, revealed that the water supply reliability and the agricultural water supply increased, regardless of the climate change scenarios. By simulating the reservoir water storage considering the instream flow post completion of the embankment raising project, it was found that water shortage in the reservoir in the future is not likely to occur when it is supplied with an appropriate instream flow. The range of instream flow tends to decrease over time under RCP 8.5, in which the greenhouse gas reduction policy was not executed, and the restoration of reservoir storage was lower in this scenario than in RCP 4.5, in which greenhouse gas reduction policy was executed.

Oriental medicine thinks life and death as the following. 1. The universe seems to be a kind of organism which is divided into 3 branches, as Heaven, Earth and Man. Man is not created from nihil by the Creator. Heaven and Earth by their interaction operate to produce man. This is similiar that zygote is not created from nihil, and that sperm and ovum are transformed into zygote by their interaction. The symbolic meaning of sperm is Heaven, and that of ovum is Earth. Mind and body, as well as spirit and body, are not the real, but artificial words for the purpose of observing and expressing one man. So there is not spiritual substance as distinct from body. The expected life span of man is subjected to change, and is always becoming through life. Fate, the Creator and the world to come cannot be said to be. 2. After one's death, man is transformend into Heaven and Earth. Dying is this process of transformation. Although man comes into existence and closes one's life, the total life of the universe does not change. The criteria of determination of death is not in cell death, but in somatic death. Somatic death divided into 2 branches, one is heart-lung death, the other is brain death. For the standard of health changes ceaselessly as time goes by, aging and dying is not the process of losing health. Because of mind cannot be seperated from body, we'll feel at ease bodily and mentally in healthy dying. The completion of lifetimes is the value of healthy dying. 3. From the viewpoint of these, we must think to let a person die healthily is the right medical ethics. The way to let a person die healthily is divided into 3 branches, one is treatment, another is prevention and the other is promotion of health. We should treat and prevent death of sickness, but take care of healthy dying.

Background: Despite progress in treatment, Stanford type A aortic dissection is still a life-threatening disease. In this study, we analyzed surgical outcomes in patients with Stanford type A aortic dissection according to the extent of surgery at Daegu Catholic University Medical Center. Methods: We retrospectively analyzed 98 patients with Stanford type A aortic dissection who underwent surgery at our institution between January 2008 and June 2018. Of these patients, 82 underwent limited replacement (hemi-arch or ascending aortic replacement), while 16 patients underwent total arch replacement (TAR). We analyzed in-hospital mortality, postoperative complications, the overall 5-year survival rate, and the 5-year aortic event-free survival rate. Results: The median follow-up time was 48 months (range, 1-128 months), with a completion rate of 85.7% (n=84). The overall in-hospital mortality rate was 8.2%: 6.1% in the limited replacement group and 18.8% in the TAR group (p=0.120). The overall 5-year survival rate was 78.8% in the limited replacement group and 81.3% in the TAR group (p=0.78). The overall 5-year aortic event-free survival rate was 85.3% in the limited replacement group and 88.9% in the TAR group (p=0.46). Conclusion: The extent of surgery was not related to the rates of in-hospital mortality, complications, aortic events, or survival. Although this study was conducted at a small-volume center, the in-hospital mortality and 5-year survival rates were satisfactory.

This study aimed to see if as companion animals living with human beings, dogs could provide emotional stability or play a therapeutic role for human beings. Of 12 middle school boys as victims of school violence, 6 were assigned to the experimental group that was provided with an animal-assisted therapy program over a total of 12 sections, one section per week, 60 minutes per section, between September and November 2011, followed by post-test 1 and, one month later, post-test 2. In the experimental composition, the remaining 6 boys were assigned to the comparison group that was allowed to read freely. Analysis was performed by using the scales of depression and self-esteem, and the results showed that the experimental group provided with the animal-assisted therapy program generated more significant therapeutic effects than the comparison group. The therapeutic effects were found to persist one month after the completion of the program. Therefore, it is believed that sensitive adolescents who suffer from depression or have lost self-esteem because of school violence can significantly benefit from an animal-assisted therapy program by reducing the recovery time or by getting lots of help with emotional stability. Further research on the basis of this study is expected to help adolescents with emotional therapy in other areas.

The purpose of this study is to draw implications through a case study on the curriculum operation of a professor who operated a programming subject as a PBL(project-based learning) method in an untact situation due to COVID-19. A survey was conducted for first-year freshmen students to determine their learning condition before project implementation. Based on the results of the questionnaire, individual interviews were conducted to identify the needs for education, and then, basic grammar for project completion and lectures that segmenting each stage of the project were composed. Repeated learning was induced through weekly quizzes, and feedback was given by giving time in advance until the project deadline. 23 students (40 students in total) completed the project. The remaining 17 students took the exam but did not complete the project. The purpose of this study is significant in that it investigated whether a project can be carried out through instructional design, execution, and interaction while operating a programming subject through PBL in the COVID-19 environment.

The final consolidation settlement is important factor in soft ground improvement because of settlement management and completion time. The compression index, which is slope of primary consolidation curve, is commonly used for the calculation of final consolidation settlement in clay layer. The existing final consolidation settlement is calculated in total consolidation layer that is assumed as one layer. This paper describes analysis result of the acquired settlement, when the consolidation layer is divided as several layer. The consolidation settlement increased according to increase of the divided layer and then it is converged. This result was unrelated to surcharge load. The division effect of layer is very high when the surcharge load is less than the consolidation layer thickness. The division effect of layer is 1.2 to 1.4 in the general surcharge load, and this value can be apply as safety factor in the calculation of final consolidation settlement.

Purpose: This study was designed to evaluate the efficacy and safety of topically applied recombinant human epidermal growth factor (rhEGF) for the prevention of radiation-induced dermatitis in cancer patients. Materials and Methods: From December 2010 to April 2012, a total of 1,172 cancer patients who received radiotherapy (RT) of more than 50 Gy were prospectively enrolled and treated with EGF-based cream. An acute skin reaction classified according to the Radiation Therapy Oncology Group 6-point rating scale was the primary end point and we also assessed the occurrence of edema, dry skin, or pruritus. Results: The percentage of radiation dermatitis with maximum grade 0 and grade 1 was 19% and 58% at the time of 50 Gy, and it became 29% and 47% after completion of planned RT. This increment was observed only in breast cancer patients (from 18%/62% to 32%/49%). Adverse events related to the EGF-based cream developed in 49 patients (4%) with mild erythema the most common. Skin toxicity grade >2 was observed in 5% of the patients. Edema, dry skin, and pruritus grade ${\geq}3$ developed in 9%, 9%, and 1% of the patients, respectively. Conclusion: Prophylactic use of an EGF-based cream is effective in preventing radiation dermatitis with tolerable toxicity. Further studies comparing EGF cream with other topical agents may be necessary.

Purpose: The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Materials and Methods: Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. Results: The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Conclusion: Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

Pupose : The Korean cancer pain assessment tool (K-CPAT) was developed in 2003 is consisted of questions concerning the pain location, quality of pain, present pain intensity, symptoms associated with pain, and psychosocial/spiritual pain assessments. This study was done to evaluate the reliability and validity of K-CPAT. Methods : A Stratified, proportional-quota, clustered, systematic sampling has been employed. Study population (903 cancer patients) was 1% of the target population (90,252 cancer patients). A total of 314 (34.8%) questionnaires have been collected. Results : Average pain score (5 Likert scale) by cancer type and at-present average pain score (VAS, $0{\sim}10$) were correlated (r=0.56, P<0.0001), and showed a moderate agreement (kappa=0.364). Mean score of satisfaction was 3.8 ($1{\sim}5$). The average time of completion of the questionnaire was 8.9 minutes. Conclusions: The K-CAPT is a reliable and valid instrument for the assessment of Cancer Pain for Korean.
