Background: The Glasgow Prognostic Score (GPS) is calculated from measured CRP and albumin levels. We here evaluated the significance of the GPS in patients with resected pulmonary adenocarcinoma. Materials and Methods: The present study included 156 patients with lung adenocarcinoma who underwent lobectomy at Kanazawa Medical University between 2002 and 2012. Classification was into three groups: those with normal albumin (>=3.5 g/dl) and C-reactive protein (CRP) (<=1.0 mg/dl) levels were classified as GPS 0 (n =136), those with low albumin (<3.5 g/dl) or elevated CRP (>1.0 mg/dl) levels as GPS 1 (n = 16), and those with low albumin (<3.5 g/dl) and elevated CRP (>1.0 mg/dl) levels as GPS 2 (n = 4). We retrospectively investigated relationships between the patient characteristics including the GPS, and disease-free survival and cancer-specific survival. Results: The pathological stages of the patients were as follows: IA (n=78, 50%), IB (n=31, 19.9%), IIA (n=20.0, 12.8%), IIB (n=9.0, 5.7%), and IIIA (n=18.0, 11.5%). Lobectomy was performed in all cases. The average GPS was 0.15 (0-2) and showed significant relationships with stage and tumor size. The 2-year survival rates in patients with GPS0, 1 and 2 were 81.4%, 38.4%, and 25.0%, respectively. Clear correlations were noted with both cancer-specific survival and disease-free survival. Furthermore, multivariate analysis revealed that GPS was a significant prognostic factor. Conclusions: The GPS could be a prognostic factor for patients with resected pulmonary adenocarcinoma.

Study on Function of Natural Aeration at Semi-aerobic Landfill by Measuring Gas Velocity and Temperature

( Junya Machida ),( Toshihiko Matsuto ),( Takayuki Matsuo ) 한국폐기물자원순환학회(구 한국폐기물학회) 2015 한국폐기물자원순환학회 3RINCs초록집 Vol.2015 No.-

Even after landfill is closed, biological degradation process and, production of leachate and landfill gas, continues for several decades or longer. In Japan, semi-aerobic structure is recommended for supply air into waste layer by natural convection. The heat generated by aerobic microorganism raise the temperature of waste, then the difference of temperature between waste and the atmosphere drives air to flow into waste layer from the end of leachate collection pipe. In the previous research by authors, there was found the positive correlation between gas velocity and the temperature at exit of gas vent, so the relation can be used to evaluate the soundness of natural aeration function of semi-aerobic landfill. In this study, data of gas velocity and temperature was collected from 26 landfills from which gas flow is detected. Additional measurement was also asked to increase data on the relation between gas velocity and temperature only. As a result, only 7 landfills were considered sound semi-aerobic landfill.

Objective: To assess the efficacy of the FIGO 2018 classification system for nodal-specific classifications for early-stage cervical cancer; specifically, to examine the impact of nodal metastasis on survival and the effect of postoperative treatments, according to histological subtypes. Methods: This society-based retrospective observational study in Japan examined 16,539 women with the 2009 FIGO stage IB1 cervical cancer who underwent primary surgical treatment from 2004 to 2015. Associations of cause-specific survival (CSS) with nodal metastasis and postoperative adjuvant therapy were examined according to histology type (squamous cell carcinoma [SCC], n=10,315; and non-SCC, n=6,224). Results: The nodal metastasis rate for SCC was higher than that for non-SCC (10.7% vs. 8.3%, p<0.001). In multivariable analysis, the impact of nodal metastasis on CSS was greater for non-SCC tumors (adjusted-hazard ratio [HR], 3.11; 95% confidence interval [CI], 2.40– 4.02) than for SCC tumors (adjusted-HR, 2.20; 95% CI, 1.70–2.84; p<0.001). Propensity score matching analysis showed significantly lower CSS rates for women with pelvic nodal metastasis from non-SCC tumors than from SCC tumors (5-year CSS rate, 75.4% vs. 90.3%, p<0.001).The CSS rates for women with nodal metastasis in SCC histology were similar between the postoperative concurrent chemoradiotherapy/radiotherapy and chemotherapy groups (89.2% vs. 86.1%, p=0.42), whereas those in non-SCC histology who received postoperative chemotherapy improved the CSS (74.1% vs. 67.7%, p=0.043). Conclusion: The node-specific staging system in the 2018 FIGO cervical cancer classification is applicable to both non-SCC tumors and SCC tumors; however, the prognostic significance of nodal metastases and efficacy of postoperative therapies vary according to histology.

Objective: Hospital treatment volume affects survival in patients with endometrial cancer; notably, initial treatment at high-volume centers improves survival outcomes. Our study assessed the effect of hospital treatment volume on cost-effectiveness and survival outcomes in patients with endometrial cancer in Japan. Methods: A decision-analytic model was evaluated using the following variables and their impact on cost-effectiveness: 1) hospital treatment volume (low-, intermediate-, and high-volume centers) and 2) postoperative recurrent risk factors based on pathological findings (high- and intermediate-risk or low-risk). Data were obtained from the Japan Society of Obstetrics and Gynecology database, systematic literature searches, and the Japanese Diagnosis Procedure Combination database. Quality-adjusted life years (QALY) was used as a measure of effectiveness. The model was built from a public healthcare perspective and the impact of uncertainty was assessed using sensitivity analyses. Results: A base-case analysis showed that the incremental cost-effectiveness ratio at high-volume centers was below a willingness-to-pay (WTP) threshold of ¥5,000,000 with a maximum of ¥3,777,830/4.28 QALY for the high- and intermediate-risk group, and ¥2,316,695/4.57 QALY for the low-risk group. Treatment at the high-volume centers showed better efficiency and cost-effectiveness in both strategies compared to intermediate- or low-volume centers. Sensitivity analyses showed that the model outcome was robust to changes in input values. With the WTP threshold, treatment at high-volume centers remained cost-effective in at least 73.6% and 78.2% of iterations for high- and intermediate-risk, and low-risk groups, respectively. Conclusion: Treatment at high-volume centers is the most cost-effective strategy for guiding treatment centralization in patients with endometrial cancer.

Who Supports Nuclear Armament in Japan? Threat Perceptions and Japan's Nuclear Armament

Satoshi Machida 서울대학교행정대학원 2014 Asian Journal of Political Science Vol.22 No.2

The security environment in East Asia has been going through drastic changes. As China and North Korea pose a serious threat to Japan, the Japanese are now more concerned about the security issue in the region. Recognizing the highly volatile situation Japan is facing, the purpose of this study is to examine the issue of nuclear proliferation by focusing on people's attitudes in Japan. More specifically, it systematically analyzes the factors that can determine people's opinions of nuclear weapons by utilizing the survey data. The result of the statistical analysis suggests that threat perceptions significantly boost people's support for nuclear armament. Advancing our understanding of nuclear proliferation from a unique perspective, this study makes an important contribution to the literature, thus helping us predict Japan's security policy.

海洋都市下関と朝鮮半島-朝鮮通信使を中心として-

町田一仁(Machida Kazuto) 부경대학교 인문사회과학연구소 2019 인문사회과학연구 Vol.20 No.3

下関は日本の本州の最西端に位置する海陸交通の要衝で、日本国内はもとより、朝鮮半島(韓半島)や中国とも有史以来、密接なつながりを持ち、海洋都市として発展した。特に朝鮮半島とは一衣帯水の地であり、人、モノ、情報が海の道を介して活発に行き交って、前近代では朝鮮半島の文化を強く受容し、近代以降は日本の朝鮮半島侵略の拠点となった。 本稿は、海洋都市下関と朝鮮半島の関係について時代別に概観するとともに、当地における朝鮮通信使御馳走および朝鮮漂流民送還の様相について紹介するものである。 朝鮮通信使にとって下関は、使行の安全を確保する重要な地であった。そのため、対馬易地聘礼となった1811年を除く全ての朝鮮通信使が目的地への往復の途次に必ず寄港している。この地での朝鮮通信使御馳走は長州藩毛利氏の役割であり、毛利氏は各使行とも懇切丁寧に応接し、1711年の使行では｢長門下之関御馳走一番｣と評価された。また、下関の客館であった阿弥陀寺において、長州藩の学者は通信使と積極的に学術交流を行って、藩内の学問興隆に貢献した。朝鮮通信使も下関の地理的･軍事的拠点性に着目しており、詳細な観察を行って使行録に記録している。 朝鮮通信使の往来によりもたらされた両国の平和的な外交関係は、朝鮮漂流民の救助と送還体制を確固たるものとした。近世下関には44回376人の朝鮮人が漂着しているが、全ての漂流民がこの地の人々に救助･保護されて、無事朝鮮国に送還されている。 Shimonoseki is placed in the westernmost of Japan Honshu, and it is the stronghold place of the amphibious trade. Therefore Shimonoseki is the representative marine city which has been interchanged many regions with inside and outside of Japan, such as Korea and China since the dawn of history. Especially Shimonoseki is separated from Korean peninsula by a narrow strip of water, the people and things and information of two regions exchanged frequently by the sea route. Shimonoseki accepted the culture of the Korean peninsula strongly, but it was changed to the base of invasion by Japan from modern-age. Here, I would give a conspectus of the relations of between marine city Shimonoseki and the Korean peninsula in order of the times, besides introduce about the Chosen Chusinsi receptions and the deportations of Korean drifters in Shimonoseki. Shimonoseki was the very important place for security of the Chosen Chusinsi mission. Therefore all Chosen Chusinsi mission expect 1811 year was visited at Shimonoseki by all means. The receptions of Shimonoseki was taken charged by Moori Lord of Chou Shu feud, Moori Lord went to meet Chosen Chusinsi mission on arrival with all his heart every times. Especially the Chosen Chusinsi mission of Shimonoseki in 1711 year was estimated as the best reception such as Nagato Shimonoseki Gochisou Ichiban. Besides many scholars of Chou Shu interchanged academic exchange with the Chosen Chusinsi mission actively in Amita Temple, and it made a great contributions to cultural development of Chou Shu region. The Chosen Chusinsi mission were concerned about of the geographical and militarily important position, watched and wrote in detail in their journals. The exchange of Chosen Chusinsi made the peaceful diplomatic relations between Japan and Korea, and the rescue and the deportations of Korean drifters from Japan to Korea were settled in pre-modern ages. 376 Korean persons were drifted to Shimonoseki ashore by 44 times in pre-modern ages. All drifting Korean persons were rescued and protected by the people of Shimonoseki, and they were sented to Korea safely.
