This paper reviewed and summarized the experimental studies conducted during last three decades to evaluate the structural integrity and to establish the acceptance criteria for piping system of nuclear power plants (NPPs) under seismic loading condition. These experimental studies contain the results of large-scale piping system tests under excessive seismic loading as well as standard specimen tests, simplified piping specimen tests, and piping components tests under simplified dynamic and cyclic loading. These would be useful as a basis for establishing integrity assessment procedure and acceptance criteria for piping systems of NPPs under beyond design basis earthquake (BDBE) conditions, and also could be used in planing the scope and direction of further related researches.

Conversion disorder lacks temperamental grounds and is a type of somatoform disorder that includes alteration or loss of physical functions implicated in physical deficit suggestive psychological conflict. There is high incidence of return of conversion disorder and difficulty in producing exact approaches of cure and apparent effects of remedy with symptomatic treatment alone because of its complex clinical symptoms. The approach of Oriental Medicine in treatment of conversion disorder is to apprehend relative symptoms from the syndrome combined with several annexational symptoms centering around sequential symptoms. Thereupon, author made a Ganyanghwapung comprehensive diagnosis was conducted using Oriental Medicine measures by differential diagnostic methods in psychosomatic patients whose cases are diagnosed as conversion disorder. Then, Cheonmagudeungeum Gagambang was prescribed for them and it brought on satisfactory effects from the first or second treatment. There have been many cases reporting the application of Oriental Medicine treatment to conversion disorder to date and outcomes have also been favorable. Results of this study likewise suggest that this Oriental Medicine treatment for conversion disorder is effective.

As society ages, the seriousness of Parkinson's disease in the elderly increases. This study was performed in order to evaluate the effect of Korean medical treatments on Parkinson's symptoms. An elderly patient was diagnosed with Parkinson's disease by clinical symptoms, which were resting tremor, pill-rolling tremor and mild bradykinesia. We treated her disease with Korean medical treatment, including herbal medicine and acupuncture therapy and excluding western medication. For the herbal medicine, Insamyangyeong-tang (人參養榮湯), Bobi-tang (補脾湯), Dokhwaljihwang-tang (獨活地黃湯) and Sipimijihwang-tang (十二味地黃湯) were primarily used. In result, the clinical symptoms, measured by unified Parkinson's disease rating scale (UPDRS) and modified Hoehn and Yahr stage (H-Y stage), of Parkinson's disease in this patient had improved after the Korean medical treatment. This study suggests that Korean medical treatments can be applicable to improve symptoms in patients with Parkinson's disease.

Background : Liver cirrhosis is a disease of the liver in which normal cells are replaced by scar tissue. This condition results in the failure of the liver to perform many of its usual functions. Liver cirrhosis includes ascites, jaundice, portal hypertension, varices etc. Objectives : This study was to see if there is a decrease in ascites of liver cirrhosis to under acupuncture and herbal treatment to test their validity. Methods : Measuring the response to treatment of ascites by giving pyengwie-san hap wieryungtang gamibang and treating the patient with acupuncture, these clinical symptoms were observed: weight, abdominal circumference, abdominal SONO, chest X-ray, and lab findings. Results : Over 18 days the daily average loss of weight and abdominal circumference 0.43kg and 0.56cm, respectively. Lab findings of liver functions showed improvement. Conclusions : This report shows a role for acupuncture and herbal treatment for treating ascites in liver cirrhosis.

Invasive alien species (IAS) can affect agricultural ecosystem negatively and critically. The geographical distributions of nine IAS plants in Korean orchards and uplands were investigated. Ambrosia artemisiifolia distributed widely in Korean peninsula and Ambrosia trifida distributed intensively in Gyeonggi-do. Aster pilosus distributed in Gyeonggi-Gangwon region and Lactuca scariola distributed linear region from the north-western to south-eastern part of Korea. Hypochaeris radicata distributed mainly in Jeju-do and Solanum carolinense distributed in eastern Gyeonggi-do. Rumex acetosella and Sicyos angulatus sporadically occurred in Korean croplands and Eupatorium rugosum was found in one region only. The distribution of IAS plants in croplands was very similar to that in non-croplands suggesting that ecological position of arable lands is not different from that of non-arable lands. Therefore, IAS plants in the croplands should be managed for not only prevention of yield reduction, but also protection or maintenance of original ecosystem. Development of management methods apposite to current Korean status are required to control IAS plants in croplands. 본 연구에서 국내의 농경지 내 생태계교란식물의 분포를 알아보고자 한다. 생태계교란식물 9종의 지역적 분포를 알아보기 위해 분포지도를 작성하였다. 단풍잎돼지풀과 돼지풀은 전국적인 분포를 보였으나 단풍잎돼지풀은 경기북부에 집중적으로 발생하고 있었고, 돼지풀은 경우에는 강원 및 전라 지역을 제외한 전국에 고르게 분포하고 있었다. 미국쑥부쟁이는 경기도 및 강원도 지역에 집중적으로 분포하고 있었으며, 가시상추의 경우 서북-동남 방향으로 분포하고 있었다. 서양금혼초는 제주도에 집중적으로 발생하고 있었고, 도깨비가지는 주로 경기 동부 지역에 분포하고 있었다. 애기수영과 가시박의 경우 전국에 산발적으로 발생하고 있었으나 경기도 지역에 상대적으로 많은 비율로 발생하고 있었으며, 서양등골나물은 경기도 연천군의 과수원 및 밭작물 재배지에만 발생하는 것으로 나타났다. 농경지 내 생태계교란식물의 분포는 비농경지와 거의 같은 경향을 보였으며, 이는 농경지의 생태적 지위가 비농경지와 다르지 않음을 의미한다. 따라서 작물의 수량 및 품질을 떨어뜨리기 때문에 잡초를 관리해야한다는 인식에서 더 나아가 주변 생태계에 부정적인 영향을 줄 수 있기 때문에 제거해야 한다는 인식의 전환이 필요하다. 또한, 각 생태계 교란식물의 효율적인 방제를 위해 제초제 약효/약해 연구나 발아생리 연구와 같은 다양한 연구가 필요한 실정이다.

전단머리 보강 CFT기둥-RC 무량판 접합부의 펀칭전단강도

This paper summarizes full-scale gravity-load test results on CFT column-to-RC flat plate connections reinforced with shearhead. CFT construction has many structural and constructional advantages over conventional steel and RC column construction and is gaining wide acceptance. Meanwhile the use of RC flat plate system in the basement and residential floors of tall buildings is often mandatory to reduce story height and enable rapid construction in domestic practice. Combining CFT column and flat plate floor is expected to result in further rapid construction. However, the issues related to connecting CFT column to RC flat plate have not been fully addressed yet. Several promising connecting schemes by using steel shearhead were proposed and tested in this study. Test results showed that the proposed connection can exhibit the punching shear strength higher than RC flat plate counterparts. An empirical formula that can reasonably predicts the punching shear strength of the proposed connection was also proposed. 본 논문은 전단머리를 갖는 CFT기둥-RC 무량판 접합부에 대한 실물대 실험연구를 요약한 것이다. CFT구조는 여러 가지 구조 및 시공 상의 장점으로 인하여 국내 건설현장에서 상대적으로 짧은 시간에 폭넓게 수용되고 있다. 한편 RC 무량판 구조는 층고절감 및 공기 단축 측면의 장점으로 국내의 지하주차장이나 주거용 건물에 필수적 구조시스템으로 널리 사용되고 있다. 이 두 구조시스템을 조합함으로써 공사기간의 획기적 단축 등 여러 시공 및 구조상의 이점을 극대화할 수 있을 것으로 예상된다. 그러나 CFT기둥-RC 무량판 접합부의 효율적인 디테일은 국내 외적으로 아직 충분히 연구된 바가 없어서 이 분야의 연구가 매우 필요한 실정이다. CFT기둥-RC 무량판 접합부의 구조성능에 영향을 미칠 수 있는 여러 가지 변수를 고려하여 접합상세를 제안하고 실험을 통하여 검증하였다. 실험결과 본 연구에서 제시된 CFT기둥-RC 무량판 접합상세의 펀칭강도는 ACI에서 규정한 RC 무량판 펀칭강도와 동등하거나 상회하는 것을 확인할 수 있었다. 실험결과를 토대로 CFT기둥-RC 무량판의 펀칭전단강도 예측식을 제안하였다.

This study investigated deformation behavior of major nuclear structural materials under cyclic loading conditions via cyclic stress-strain test. The cyclic stress-strain tests were conducted on SA312 TP316 stainless steel and SA508 Gr.3 Cl.1 low-alloy steel, which are used as materials for primary piping and reactor pressure vessel nozzle respectively, under cyclic load with constant strain amplitude and constant load amplitude at room temperature (RT) and $316^{\circ}C$. From the results of tests, the cyclic hardening and softening behavior, stabilized cyclic stress-strain behavior, and ratcheting behavior of both materials were investigated at both RT and $316^{\circ}C$. In addition, appropriate considerations for cyclic deformation behavior in the structural integrity evaluation of major nuclear components under excessive seismic condition were discussed.
