Objective: Vitamin D deficiency can either cause or aggravate osteopenia and osteoporosis, and that can lead to an increased risk of fracture. We studied associations between serum vitamin D level and skeletal complications including bone pain in multiple myeloma patients. Methods: This study reviewed the medical records of 35 multiple myeloma patients in Soonchunhyang University Bucheon Hospital from January, 2013 to May, 2014. The patients were classified as three groups according to the total vitamin D level: above 20 ng/ mL as sufficient group, from 10 to 20 ng/mL as insufficient group, and below 10 ng/mL as deficient group. Results: The incidence of fracture complication, the number of fracture, and the number of the cases of severe fracture that needed surgical intervention did not show statically significant difference in the three groups according to the total vitamin D level. As the results presented as graphs, the number of indicator of skeletal complications and total vitamin D level showed negative relationship. In the logistic regression analysis, analgesic use due to bone pain and the number of total analgesic use were significantly different in three groups (P=0.036, P=0.041), respectively, and showed a negative correlation between the level of vitamin D and number of analgesics had negative correlation. Conclusion: The measurement of serum total vitamin D level at the initial diagnosis in multiple myeloma patients and the proper treatment in the deficient patients would reduce the skeletal complications and moreover improve the quality of life.

Japanese troops in Korea was activated under the name ‘Choseon-Juchagun’ in 1910. And it reorganized their stationary form. In April 1915, lobbying for military camps started in colonial Korea. Lobbying centered on the local elites. Japanese residents in Korea took the lead in the initial lobbying. They wrote and filed petitions with the Japan Department of the Army. In name of "Development," each region contended to invite a military camp. The aspect of lobbying gradually included the Korean elite internally, and widened to other areas in colonial Korea externally. They also promised to donate land. Terauchi Masatake tried to control lobbying. However, Japanese Army wanted to save the budget. They granted a petition in Hamhung and Daegu, and decided the deployment of regiments. But, protests began in Daejeon. Terauchi demanded again the deployment of additional troops in Daejeon. In the end, Army divided the regimental force in Daegu, and deployed a battalion of troops in Daejeon. 본 글은 1915년 조선 주둔 일본군 상주사단의 군영 배치지역 선정과 지역사회의 군영 유치운동의 양상에 대해 검토하였다. 1915년 6월 일본 제국의회는 상주사단 설치안을 승인하고, 육군은 군영 배치지역의 조사를 추진하였다. 한편 재조일본인과 일부 조선인은 각지에서 군영 유치운동을 전개하였다. 재조일본인은 운동을 결성하고 주도하여, 청원서를 작성하고 육군성에 제출하였다. 공직자와 직접 면담을 하는 곳도 있었다. 청원서는 각 지역의 이점을 강조하고, 일본의 침략·식민통치가 ‘발전’을 가져왔다고 미화하였다. 점차 운동양상은 지역적·계층적으로 확장했다. 지역 간 경쟁의식을 드러내는 경우도 나타났다. 토지를 기부하겠다는 조건을 추가하거나, 다른 지역의 운동을 비판하는 예도 빈발했다. 공직자도 관여하였다. 총독부는 유치운동이 통치에 문제를 낳을 수 있다고 우려하였다. 이에 육군 측에 협조를 요청했으나, 육군은 대구·함흥의 유치운동을 일부 수용하였다. 그 결과 8월 초 군영의 배치지역이 정해졌으나, 대전에서 유치탈락에 따른 시위가 일어났다. 이에 총독과 육군성이 재차 협의하였다. 결국, 대구에 배치할 연대병력 중에서 1개 대대를 대전에 분산 배치하기로 확정했다.

太白山 北部 地域에 分布하는 三和花崗岩의 巖石學的 硏究

이민성,장호완,김완섭 한국지구과학회 1987 韓國地球科學會誌 Vol.8 No.2

The principal consisting rocks of study area are Precambrian metasedimentary bedrocks, Cambro-ordovician sedimentary rocks and Samhwa granite which have intruded these metasedimentary and sedimentary rocks. The reddish K-feldspar bearing Samhwa granite presettts miarolitic texture and graphic intergrowth between quartz and K-feldspar. The granite, homogeneous in chemical composition of major elements, belongs to Calc-alkali rocks of subalkali series. According to AMF diagram, the granite was crystallized at the latest stage of the differentiation of magma. The Samhwa granite belongs to I-type granitoids and magnetite-series granitoids. Especially, this granite is thought to be crystallized in the epicrust with high oxygen fugacity. The Samhwa granite has similar characteristics to masanite of cretaceous granitic rocks of Gyeongsang basin in the petrological and petrochemical properties. The biotite age of the granite by K-Ar age dating is 50.1±1.5. Finally, contact metamorphic zone of limestone by granite intrusion contains distinct minerals such as diopside, brucite, tremolite and muscovite, which indicate low temperature metamorphic grade.

The Taehyedogyŏng chongyo attributed to Wŏnhyo is a commentary of Xuanzang’s last translation, Da bore boluomiduo jing (Skt. Mahāprajñāpāramitā Sūtra). However, the main contents consist of somewhat far from prajñā, such as the three natures and tathāgatagarbha. This study reveals that these contents are critique of Kuiji's arguments; that is to say, Wŏnhyo directly took part in the debate on ‘the ‘Distinctiveness of the Five Natures(五性各別說)’ and on ‘Emptiness and Having / Existence(空有)’, which were big issues in 7th century East Asian Buddhism.

Some components in uranium-bearing formations which consist mainly of black shale, slate. and low grade coal-bearing formation of Ogcheon Belt were processed statistically in order to find out the geochemical correlations with uranium. Geochemical enrichment of uranium, vanadium and molybdenum in low grade coal-bearing formations and surrounding rocks is remarkable in the studied area. Geochemical correlation coefficient of uranium and molybdenum in the rocks displays about 0.6, and that of uranium and fixed carbon about 0.4. Uranium and vanadium in uranium-bearing low grade coals denote very high correlation with fixed carbon, which is considered to be responsible for enrichment of metallic elements, especially molybdenum. Close geochemical correlation of uranium-molybdenum couple in the rocks can be applied as a competent exploration guide to low grade uranium deposits of this area.

This article reviewed the Imperial Japanese Army Air Force`s installation and expansion of facilities in Pyongyang during the 1920s. At the military level, the characteristics of the early Japanese army aviation forces made it possible to plan resulted in the formation of an aviation unit in Joseon. The reason why Pyongyang became an aviation station was then confirmed using survey data for on the selection of sites. The army focused on the route from Japan’s “Inland” to the continent. Daegu and Pyongyang, the Japanese military garrison in Joseon, drew attention, and Pyongyang was selected as an area where various military and economic advantages and disadvantages could be compromised. The military flight training was conducted at the Army’s aviation unit in Pyongyang, and the connection between Joseon and the “Inland” and its influence on the Chinese continent were expanded. As its aeronautical influence gradually crossed the border, Consequently the army organized additional bomber units to realize an active expansionist policy. In summary, the installation and operation of the army air force stationed in Pyongyang set the foundation for a connection with Japan’s “Inland,” maintenance of security within Joseon, and continental invasion. At the social level, the presence of the aviation force encouraged the desire for “development” of local communities. In the provinces, Attraction campaigns were actively held. The army attempted to solve the problem of stationing expenses by fostering this drive for “development.” The Governor -General also helped in this endeavor. However, the positions of the army and the Governor-General were not always in agreement. The Governor-General, Japanese Army, and local influential groups formed an axis of the colonial system by competing, clashing, or uniting according to their respective interests. Meanwhile, during the process of installing a bombing practice field, it was confirmed that most ordinary Koreans were recognized only as unilateral objects of the governance system and objects of suppression, coercion, and deception. Unlike the tension of conflict due to gains and losses within the colonial power, ordinary Koreans were not given such space. 본 글은 1920년대 조선 주둔 일본군 항공대의 설치와 설비 확장 과정을 검토하였다. 군사적 차원에서, 초기 일본육군 항공전력의 특징은 조선군 항공대 신설 계획의 배경이었다. 다음으로 왜 평양이 항공대 주둔지가 되었는지, 부지 선정을 위한 조사 자료를 통하여 확인하였다. 육군이 주안점을 두었던 것은 일본 ‘내지’에서 대륙 방면으로 이어지는 경로였다. 그 중에 조선군 기존 위수지였던 대구와 평양이 주목받았고, 평양이 여러 장단점을 절충할 수 있는 지역으로 선정되었다. 평양 주둔 항공대를 기반으로 육군의 비행훈련이 진행되었고, ‘내지’와의 연결과 더불어 대륙으로의 영향력을 넓혀갔다. 육군의 항공전력 투입 범위가 조선 북부 국경을 넘어갈 정도가 되자, 육군은 정찰 및 전투 분과에 폭격대를 추가하였다. 보다 적극적인 팽창주의 정책을 실현하기 위해서였다. 평양 주둔 항공대의 설치와 운용을 통하여, ① 일본 ‘내지’와의 연결 ② 조선 내 ‘치안유지’ ③ 대륙침략의 단초가 마련되었다고 할 수 있다. 사회적 차원에서 항공대 주둔은 지역사회의 ‘개발’ 욕망을 자극하는 것이었다. 지역 간 유치운동이 활발하게 일어났다. 육군은 이러한 ‘개발’ 욕망을 자극하여 비용문제 등을 해결하고자 했다. 육군과 총독부의 입장이 항상 균일하지는 못했다. 지역사회의 유력자 집단, 그리고 총독부와 일본육군은 자신들의 이해득실에 따라서 경합, 갈등하거나 연대하며 식민 통치체제의 한 축을 형성하였다고 할 수 있다. 그러나 이와 비교하면, 폭격 연습장 설비 과정에는 통치체제의 일방적인 객체로서만 인지되어, 탄압 혹은 강압, 기만의 대상으로만 인지되었던 대다수 일반 조선인의 모습이 확인된다. 식민권력 내에서 이해득실에 따라 갈등 및 충돌의 긴장이 존재한 것과 달리, 일반 조선인 지역주민에게는 그러한 여지가 주어지지 않았다.

The effects of pycnogenol on antioxidant enzymes in a mouse model of ozone exposure

이민성,박무균,장안수,문국영,배다정 대한내과학회 2013 The Korean Journal of Internal Medicine Vol.28 No.2

Background/Aims: Ozone is an environmentally reactive oxidant, and pycnogenol is a mixture of f lavonoid compounds extracted from pine tree bark that have antioxidant activity. We investigated the effects of pycnogenol on reactive nitrogen species, antioxidant responses, and airway responsiveness in BALB/c mice exposed to ozone. Methods: Antioxidant levels were determined using high performance liquid chromatography with electrochemical detection. Nitric oxide (NO) metabolites in bronchoalveolar lavage (BAL) fluid from BALB/c mice in filtered air and 2 ppm ozone with pycnogenol pretreatment before ozone exposure (n = 6) were quantified colorimetrically using the Griess reaction. Results: Uric acid and ascorbic acid concentrations were significantly higher in BAL fluid following pretreatment with pycnogenol, whereas γ-tocopherol concentrations were higher in the ozone exposed group but were similar in the ozone and pycnogenol pretreatment groups. Retinol and γ-tocopherol concentrations tended to increase in the ozone exposure group but were similar in the ozone and pycnogenol pretreatment groups following ozone exposure. Malonylaldehyde concentrations increased in the ozone exposure group but were similar in the ozone and pycnogenol plus ozone groups. The nitrite and total NO metabolite concentrations in BAL fluid, which parallel the in vivo generation of NO in the airways, were significantly greater in the ozone exposed group than the group exposed to filtered air, but decreased with pycnogenol pretreatment. Conclusions: Pycnogenol may increase levels of antioxidant enzymes and decrease levels of nitrogen species, suggesting that antioxidants minimize the effects of acute ozone exposure via a protective mechanism.

규기의 반야경 교판(敎判)과 사분설(四分說)에 대한 원효의 비판적 견해

이민성 한국종교교육학회 2023 宗敎敎育學硏究 Vol.72 No.-

[PURPOSE] This paper examines Taehyedogyŏng chongyo(THC), a text attributed to Wŏnhyo (617~686), and clarifies its main focus. [CONTENTS] In Chapter 5 of THC, Wŏnhyo negatively critiques the classification of Jie shenmi jing, which corresponds to the interpretation of lowering Prajñāpāramitā sūtras. Before Wŏnhyo’s critique, Kuiji(632~682) had already debated this topic, but he followed the contents of Jie shenmi jing. This article shows that Wŏnhyo's critique is aimed at challenging Kuiji’s statement. Additionally, in Chapter 2, Wŏnhyo deals with Xuanzang’s Yogācāra theory, known as the Four Parts of the Mind, which was first argued in Cheng weishi lun. Wŏnhyo deliberately excludes Dharmapāla’s view, which is supported by Xuanzang and Kuiji, and upholds Dignāga’s view. This paper argues that this is also a critique of Kuiji’s view. By analyzing the distributions and frequency of quotations in THC, along with the above results, it is revealed that Wŏnhyo intended to return to the Buddhist interpretation that preceded Xuanzang’s period. [RESULTS] THC actually contains Wŏnhyo’s critiques of Kuiji’s arguments, which are situated in a larger context of Buddhist interpretations that preceded Kuiji, and through which Wŏnhyo seeks to challenge and refute Kuiji’s views.
