      • 姉妹都市提携と市民國際交流の意義

        Toshio Kusumoto 성결대학교 다문화평화연구소 2009 다문화와 평화 Vol.3 No.2

        The foundation of international cultural exchange in our county is sister city agreements, which are signed between local municipalities and foreign cities. In 1956, Dwight D. Eisenhower, the US President, proposed “People to People Program” to promote international cultural exchanges between cities in the US and around the world. The basic philosophy behind the program was that the international cultural exchange among citizens concerned would promote mutual understanding; concomitantly it would promote world peace. One of the most important scheme in President Eisenhower’s program was to develop sister city agreements among foreign municipalities. Today, the same philosophy still stands. Different from diplomatic activities between governments, which are directly affected by national interests, sister city agreements are less affected by foreign policies. To the contrary, sister city agreements often promote more grass-root cultural exchanges between cities and citizens. In Japan, before the end of world war Ⅱ, it was quiteunusual for a local municipality to sign a sister city agreement with a foreign city. The first sister city agreement signed by a Japanese city was between Nagasaki and St. Paul. Minnesota, in 1955. Japan in 1955 was still a devastated and confused country after being defeated in the war. Strict government regulations on foreign currency limited the ability to travel abroad for the average citizen; however, for the heads of municipalities and citizen this sister city agreement provided a rare opportunity to experience the outside world. The international cultural exchange between sister cities covers various aspects of societies, such as education, high culture, sports, health care, industry and administration. Through sister city agreements, a city can expect an increased number of opportunities for the international cultural exchange of citizens. The expectations for world peace were high when the cold war ended after the collapse of the Soviet Union. Unfortunately, such optimistic expectations have been proved to be only an illusion. Confrontations provoked by racial, religious or national interests, which lead to confusion and dispute, are often observed today. In such chaotic situations, mutual understanding and cooperation between individual citizens, which differ from inter governmental diplomatic relationships, should have even more important significance. Through a sister city agreement, two cities and their citizens interact with each other to create close friendship and a sense of solidarity. Thus, sister city agreements may contribute to world peace through a grass-root cultural exchange of citizens. In 1974, Kobe and Riga, the capital of the Latvian Republic, signed a sister city agreement. While under control of the Soviet Union, its citizens were strictly prohibited from making free contact or having exchanges with foreigners. However the sister city agreement has provided citizens of Riga, who were not ordinarily allowed to travel to western countries, the opportunity to visit Kobe. After Latvia obtained independence from the Soviet Union in 1990, one Riga citizen looked back and commented; “Before 1990, it was impossible to make a free contact with foreign countries for the people of Latvia. The sister city, Kobe, provided the only window, through which people of Latvia could glance at the western world”. When the Great Hanshin-Awaji Earthquake hit Kobe in 1995, many countries kindly forwarded necessary aids to the hard-hit city. The aids items from sister cities were the most needed in the city at that time. The reason sister cities could provide appropriate aid items was the strong ties between the cities. The strong ties established before the earthquake made communication easy so that information on what were the urgent necessities could be easily communicated.

        Plasmon-induced photothermal cell-killing effect of gold colloidal nanoparticles on epithelial carcinoma cells

        Al-Mamun, Md. Abdulla,Kusumoto, Yoshihumi,Mihata, Aki,Islam, Md. Shariful,Ahmmad, Bashir Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.8

        Gold colloidal nanoparticles were prepared by the liquid laser ablation of a gold metal plate in water and also by the citrate reduction of $HAuCl_4{\cdot}4H_2O$. The gold colloidal nanoparticles with the plasmonic band strongly absorb light, which is converted to the photothermal energy. This photothermal energy gives a cytotoxic effect on epithelial carcinoma cells. Interestingly, we found that the size and shape of the nanoparticles are changed by light during the photothermal process in vitro. The cervical carcinoma cell line (HeLa cell) was incubated with the colloidal gold nanoparticles and then exposed to continuous visible light at 400-600 nm with UV- and heat-cutoff filters. The distinct cell-killing effect was observed by this procedure. In the absence of the gold colloidal nanoparticles, only a small amount of cells were photothermally destroyed.

        YH1885의 체내동태(제1보) : 흰쥐에서 14C-YH1885의 단회투여시 흡수, 조직분포 및 배설

        안병락(Byung Nak Ahn),Naoki Fujio,Naotoshi Kusumoto,Yoshifumi Abe,Masaaki Odomi,이종욱(Jong Wook Lee) 대한약학회 1997 약학회지 Vol.41 No.3

        The absorption, distribution and excretion of 14C labeled YH1885 {5,6-Dimethyl-2(4-fluorophenylamino)-4-(1-methyl-1,2,3,4-tetrahydroisoquinolin-2-yl)pyrimidine hydrochloride), a new proton pumpinhibitor, were investigated in rats after a single administration of 14C-YH1885. 1. After intravenous administration of 5mg/kg, the blood level of radioactivity declined in a biphasic fashion with the mean terminal elimination half-life of 12.4hr. 2. After oral administration of 20mg/kg, the maximum blood level of radioactirity was reached at 4.0hr in female rats. The blood level of radioactivity-time profiles in male and female rats were similar, and the absorptionof 14C-YH1885 was not affected by food. 3. Appproximately 89% and 1% of radioactivity of the total dose were excreted in feces and urine, respectively. 4. Biliary excretion of radioactivity was 47.9% of the dose. Enterohepatic circulation of radioactivity was 49.6%. 5. Radioactivity was excreted maily into feces via bile. 6. The concentration of radioactivity in most tissues reached the peak level at 4.0hr after dosing, and then declined. Autoradiograms of male rats showed that the radioactivity levlels in the fat, harder's gland, liver and G-Itract were higher than those in the other tissues and the elimination of radioactivity from fat and liver was slow. 7. Autoradiograms of a pregnant rat showed that radioactivity was transferred to mammary gland, placenta and fetus. The radioactivity level in the mammary gland was higher than that in the blood.

        Association Between Body Mass Index and Functional Dyspepsia in Young Japanese People

        Yasunori Yamamoto,Shinya Furukawa,Junichi Watanabe,Aki Kato,Katsunori Kusumoto,Eiji Takeshita,Yoshio Ikeda,Naofumi Yamamoto,Katsuhiko Kohara,Yuka Saeki,Yoichi Hiasa 대한소화기 기능성질환∙운동학회 2022 Journal of Neurogastroenterology and Motility (JNM Vol.28 No.2

        Background/AimsEvidence regarding the association between body mass index (BMI) and functional dyspepsia (FD) in the Asian population is limited. Further, no study has evaluated this issue in young people in Asian and Western populations. Thus, we aim to investigate this issue among young Japanese people. MethodsThe study subjects comprised of 8923 Japanese university students. BMI was divided into 4 categories (quartiles) on the basis of the study subjects’ distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, overweight, and obese was BMI < 18.5 kg/m2, 18.5 ≤ BMI < 25 kg/m2 (reference), 25 kg/m2 ≤ BMI < 30 kg/m2, and 30 kg/m2 ≤ BMI, respectively. The definition of FD was based on the Rome III criteria. ResultsThe prevalence of FD was 1.9% in this cohort. The lowest BMI was independently associated with FD after adjustment (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.46-3.67); P for trend = 0.001). The lowest BMI was independently associated with FD in women but not in men (OR, 2.94; 95% CI, 1.59-5.77; P for trend = 0.001). Leanness was independently associated with FD in total and in women but not in men (total: adjusted OR, 2.01; 95% CI, 1.40-2.86) and women (OR, 2.19; 95% CI, 1.35-3.45). However, interaction analysis showed no significant difference for sex. ConclusionsAmong young Japanese people, BMI may be independently inversely associated with FD. Leanness may be an independent associated factor for FD in the young Japanese women.

        Association Between Eating Behavior, Frequency of Meals, and Functional Dyspepsia in Young Japanese Population

        Yasunori Yamamoto,Shinya Furukawa,Junichi Watanabe,Aki Kato,Katsunori Kusumoto,Teruki Miyake,Eiji Takeshita,Yoshio Ikeda,Naofumi Yamamoto,Katsuhiko Kohara,Syuichi Saheki,Yuka Saeki,Yoichi Hiasa 대한소화기 기능성질환·운동학회 2022 Journal of Neurogastroenterology and Motility (JNM Vol.28 No.3

        Background/AimsFunctional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort. MethodsIn this study, we enrolled 8923 Japanese university students. FD is diagnosed based on the Rome III criteria. Eating habits and frequency of meals were investigated using a self-administered questionnaire. ResultsThe FD subjects had a younger mean age, a lower body mass index, and a lower proportion of men compared to the non-FD subjects. An independent positive association between skipping breakfast and/or lunch and FD was found (adjusted ORs were 1.60 [95% CI, 1.10-2.32] for breakfast and 2.52 [95% CI, 1.04-5.18] for lunch). Skipping dinner, extra meals (snacks) or midnight snacks was not associated with FD. The prevalence of FD in subjects eating 1, 2, and 3 meals per day was 4.8%, 2.2%, and 1.7%, respectively. The frequency of meals was independently inversely associated with prevalence of FD (adjusted ORs were 1 per day: 2.72 [95% CI, 1.19-5.42], and 2 per day: 1.69 [95% CI, 1.16-2.43], P for trend = 0.001). ConclusionsIn the young Japanese people, the frequency of meals may be independently inversely associated with prevalence of FD. In particular, skipping breakfast and/or lunch was associated with the prevalence of FD.
