Objective: This study aimed to determine if the discrepancy between depression severity rated by clinicians and that reported by patients depends on key behavioral/psychological features in patients with mood disorders. Methods: Participants included 100 patients with mood disorders. First, we examined correlations and regressions between scores on the Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI). Second, we divided the participants into those who provided 1) greater ratings for the BDI compared with the HAMD (BDI relative- overrating, BO) group, 2) comparable ratings for the BDI and HAMD (BDI relatively concordant, BC) group, or 3) less ratings for the BDI (BDI relative-underrating, BU) group. Adverse childhood experiences, autistic-like traits, and coping styles were evaluated with a six-item short version of the Childhood Trauma Questionnaire (CTQ-6), the Social Responsiveness Scale for Adults (SRS-A), and the Ways of Coping Checklist (WCCL), respectively. Results: A significant correlation was found between HAMD and BDI scores. Total and emotional abuse subscale scores from the CTQ-6, and the self-blame subscale scores from the WCCL were significantly higher for the BO group compared with the BU group. The BO group also elicited significantly higher SRS-A total scores than did the other groups. Conclusion: These findings suggest that patients with adverse emotional experiences, autistic-like traits, and self-blame coping styles perceive greater distress than that evaluated objectively by clinicians. The results indicate the need for inclusion of subjective assessments to effectively evaluate depressive symptoms in patients deemed to have these psycho- behavioral concerns.

The Requirements on statistical techniques in QS-9000

YAMADA, Shu 한국품질경영학회 2000 The Asian Journal on Quality Vol.1 No.1

QS-9000 was established by Chrysler, Ford, General Motors and some Truck Manufactures to solve problems of efforts to prepare original standards for each company. When we compare the requirements in QS-9000 with those in ISO 9000, we may observe that those of QS-9000 are more specific, since the user of the standard is limited to the automobile industry. In particular, the requirements on statistical techniques are described in more detail. In this paper, we present the requirements on statistical techniques in QS-9000. Specifically, we review the contents of QS-9000 and explore the philosophy and the minimum requirement on statistical techniques behind the description.

Electronic structure of Li⁺@C₆₀: Photoelectron spectroscopy of the Li⁺@C₆₀[PF₆ ⁻] salt and STM of the single Li⁺@C₆₀ molecules on Cu(111)

<P><B>Abstract</B></P> <P>We report the scanning tunneling microscope (STM) observation of the Li<SUP>+</SUP> ion endohedral C<SUB>60</SUB> on Cu(111), prepared by means of evaporation of a high-purity Li<SUP>+</SUP>@C<SUB>60</SUB>[PF<SUB>6</SUB> <SUP>−</SUP>] salt. The electronic state of Li<SUP>+</SUP>@C<SUB>60</SUB> in the Li<SUP>+</SUP>@C<SUB>60</SUB>[PF<SUB>6</SUB> <SUP>−</SUP>] salt was also determined using photoemission and X-ray absorption spectroscopy, along with the density functional theory (DFT) calculations. In the salt, Li and PF<SUB>6</SUB> had nearly single positive and negative charge, respectively; thus the C<SUB>60</SUB> cage was practically neutral. The salt decomposed under ultra-high vacuum while heating at 400 °C. This allowed the selective deposition of Li<SUP>+</SUP>@C<SUB>60</SUB> on Cu(111). Although secondary-ion mass spectroscopy of the deposited Li<SUP>+</SUP>@C<SUB>60</SUB> film showed a decrease in the Li-content during evaporation, Li<SUP>+</SUP>@C<SUB>60</SUB> was successfully identified using STM. The DFT calculations of Li<SUP>+</SUP>@C<SUB>60</SUB> on Cu(111) suggested that the Li<SUP>+</SUP> ion was singly charged and the location of the Li<SUP>+</SUP> ion was displaced in an upward direction, which altered the local density of states in an upper section of C<SUB>60</SUB>, especially for LUMO+2. The calculated results were mostly in agreement with the bias-dependent STM and dI/dV images. However, an inconsistency was observed between the calculation and experiments in case of empty state imaging where tip-induced displacement of the Li<SUP>+</SUP> ion may occur.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Improvement of durability of an organic photocatalyst in <i>p</i>-xylene oxygenation by addition of a Cu(<small>II</small>) complex

Yamada, Yusuke,Maeda, Kazuki,Ohkubo, Kei,Karlin, Kenneth D.,Fukuzumi, Shunichi The Royal Society of Chemistry 2012 Physical chemistry chemical physics Vol.14 No.27

<P>The catalytic durability of an organic photocatalyst, 9-mesityl-10-methyl acridinium ion (Acr<SUP>+</SUP>–Mes), has been dramatically improved by the addition of [{tris(2-pyridylmethyl)amine}Cu<SUP>II</SUP>](ClO<SUB>4</SUB>)<SUB>2</SUB> ([(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP>) in the photocatalytic oxygenation of <I>p</I>-xylene by molecular oxygen in acetonitrile. Such an improvement is not observed by the addition of Cu(ClO<SUB>4</SUB>)<SUB>2</SUB> in the absence of organic ligands. The addition of [(tmpa)Cu]<SUP>2+</SUP> in the reaction solution resulted in more than an 11 times higher turnover number (TON) compared with the TON obtained without [(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP>. In the photocatalytic oxygenation, a stoichiometric amount of H<SUB>2</SUB>O<SUB>2</SUB> formation was observed in the absence of [(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP>, however, much less H<SUB>2</SUB>O<SUB>2</SUB> formation was observed in the presence of [(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP>. The photocatalytic mechanism was investigated by laser flash photolysis measurements in order to detect intermediates. The reaction of O<SUB>2</SUB>&z.rad;<SUP>−</SUP> with [(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP> monitored by UV-vis spectroscopy in propionitrile at 203 K suggested formation of [{(tmpa)Cu<SUP>II</SUP>}<SUB>2</SUB>O<SUB>2</SUB>]<SUP>2+</SUP>, a transformation which is crucial for the overall 4-electron reduction of molecular O<SUB>2</SUB> to water, and a key in the observed improvement in the catalytic durability of Acr<SUP>+</SUP>–Mes.</P> <P>Graphic Abstract</P><P>The activity of [(tmpa)Cu<SUP>II</SUP>]<SUP>2+</SUP> complex toward reactive oxygen species elongates the catalytic durability of an organic photocatalyst. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c2cp41207a'> </P>

Photocatalytic hydrogen evolution from carbon-neutral oxalate with 2-phenyl-4-(1-naphthyl)quinolinium ion and metal nanoparticles

Yamada, Yusuke,Miyahigashi, Takamitsu,Ohkubo, Kei,Fukuzumi, Shunichi The Royal Society of Chemistry 2012 Physical chemistry chemical physics Vol.14 No.30

<P>Photocatalytic hydrogen evolution has been made possible by using oxalate as a carbon-neutral electron source, metal nanoparticles as hydrogen-evolution catalysts and the 2-phenyl-4-(1-naphthyl)quinolinium ion (QuPh<SUP>+</SUP>–NA), which forms the long-lived electron-transfer state upon photoexcitation, as a photocatalyst. The hydrogen evolution was conducted in a deaerated mixed solution of an aqueous buffer and acetonitrile (MeCN) [1 : 1 (v/v)] by photoirradiation (<I>λ</I> > 340 nm). The gas evolved during the photocatalytic reaction contained H<SUB>2</SUB> and CO<SUB>2</SUB> in a molar ratio of 1 : 2, indicating that oxalate acts as a two-electron donor. The hydrogen yield based on the amount of oxalate reached more than 80% under pH conditions higher than 6. Ni and Ru nanoparticles as well as Pt nanoparticles act as efficient hydrogen-evolution catalysts in the photocatalytic hydrogen evolution. The photocatalyst for hydrogen evolution can be used several times without significant deactivation of the catalytic activity. Nanosecond laser flash photolysis measurements have revealed that electron transfer from oxalate to the photogenerated QuPh&z.rad;–NA&z.rad;<SUP>+</SUP>, which forms a π-dimer radical cation with QuPh<SUP>+</SUP>−NA [(QuPh&z.rad;–NA&z.rad;<SUP>+</SUP>)(QuPh<SUP>+</SUP>–NA)], occurs followed by subsequent electron transfer from QuPh&z.rad;–NA to the hydrogen-evolution catalyst in the photocatalytic hydrogen evolution. Oxalate acts as an efficient electron source under a wide range of reaction conditions.</P> <P>Graphic Abstract</P><P>Photocatalytic hydrogen evolution using a carbon-neutral electron donor with metal nanoparticles. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c2cp41906h'> </P>

SURFACES IN 4-DIMENSIONAL SPHERE

Yamada, Akira Korean Mathematical Society 1996 대한수학회지 Vol.33 No.1

Met $\tilde{M} = (\tilde{M}, \tilde{J}, <>)$ be an almost Hermitian manifold and M a submanifold of $\tilde{M}$. According to the behavior of the tangent bundle TM with respect to the action of $\tilde{J}$, we have two typical classes of submanifolds. One of them is the class of almost complex submanifolds and another is the class of totally real submanifolds. In 1990, B. Y. Chen [4], [5] introduced the concept of the class of slant submanifolds which involve the above two classes. He used the Wirtinger angle to measure the behavior of TM with respect to the action of $\tilde{J}$.

Difference of Human Error between Japanese and Indonesian Workers at Pipeline Construction

Yamada, Takahisa The Korean Society of Safety 2010 International Journal of Safety Vol.9 No.1

A big difference is seen in the perception of self-responsibility concerning safety, as a result of my survey on the safety measures taken in the pipeline construction at workers level between Japan and Indonesia. Specifically, when an accident occurs, a worker in Indonesia will think that the responsibility depends on the person who causes it. However a worker in Japan will think that safety is can only be protected by law and regulations. There is also another difference in the understanding of construction period. It is alright in Indonesia to take 5 times longer period than it takes in Japan if the cost is less. The idea of punctual delivery is very strong in Japan. Through this survey, points which construction industry in Japan could learn from Indonesia came to surface. In addition, over the recent years, several nasty accidents at Japanese sites were caused due to human error to disregard the law. Japanese should arouse the awareness of self-responsibility in this regard. Risk management should be upon self-recognition of each individual worker in both countries. What is important is the "work attitude education", "to grow sense of self-responsibility by thinking on one's own for one's self" in the education curriculum of man to man learning as in technical educational program.

Experimental investigation of thermo-optic effects in SiC and Si photonic crystal nanocavities.

Yamada, Shota,Song, Bong-Shik,Asano, Takashi,Noda, Susumu Optical Society of America 2011 Optics letters Vol.36 No.20

<P>We experimentally investigate and compare the thermo-optic effects of silicon carbide (SiC) and silicon (Si) photonic crystal nanocavities on their resonant wavelengths over a temperature range of 25?C to nearly 200?C by using a laser source with a wavelength close to the telecommunication wavelength range of 1550?nm. The measured results clearly show that the shift in the resonant wavelength of the SiC cavity is significantly (by a factor of 3) less than that of the Si cavity for the same ambient temperature changes. In addition, the measured results provide direct estimates of the thermo-optic coefficients (dn/dT) for thin SiC and Si as 3.8710(-5)/C and 1.6010(-4)/C, respectively, for this temperature range.</P>

Lack of Associations between Genetic Polymorphisms in GSTM1, GSTT1 and GSTP1 and Pancreatic Cancer Risk: A Multi-Institutional Case-Control Study in Japan

Yamada, Ikuhiro,Matsuyama, Masato,Ozaka, Masato,Inoue, Dai,Muramatsu, Yusuke,Ishii, Hiroshi,Junko, Ueda,Ueno, Makoto,Egawa, Naoto,Nakao, Haruhisa,Mori, Mitsuru,Matsuo, Keitaro,Nishiyama, Takeshi,Ohkaw Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.1

Background: We aimed to evaluate the role of genetic polymorphisms in tobacco carcinogen-metabolizing genes and their interactions with smoking in a hospital-based case-control study of Japanese subjects. Materials and Methods: We examine the associations of pancreatic cancer risk with genetic polymorphisms in GSTM1, GSTT1 and GSTP1, phase II enzymes that catalyze the conjugation of toxic and carcinogenic electrophilic molecules. The study population consisted of 360 patients and 400 control subjects, who were recruited from several medical facilities in Japan. Unconditional logistic regression methods were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between genotypes and pancreatic cancer risk. Results: Among the control subjects, the prevalence of the GSTM1-null genotype and the GSTT1-null genotype was approximately 56% and 48%, respectively. Cases and controls were comparable in terms of GSTM1 and GSTT1 genotype distributions. Neither of the deleted polymorphisms in GSTM1 and GSTT1 was associated with the risk of pancreatic cancer, with an age- and sex-adjusted OR of 0.99 (95%CI: 0.74-1.32) for the GSTM1-null genotype, and 0.98 (95%CI: 0.73-1.31) for the GSTT1-null genotype. The OR was 0.97 (95%CI: 0.64-1.47) for individuals with the GSTM1 and GSTT1-null genotypes compared with those with the GSTM1 and GSTT1- present genotypes. No synergistic effects of smoking or GST genotypes were observed. Conclusions: Our results indicate no overall association between the GSTM1 and GSTT1 deletion polymorphisms and pancreatic cancer risk in the Japanese subjects in our study.

Synthesis and photochemical properties of α-diketoporphyrins as precursors for π-expanded porphyrins

Yamada, Hiroko,Kuzuhara, Daiki,Ohkubo, Kei,Takahashi, Tetsuro,Okujima, Tetsuo,Uno, Hidemitsu,Ono, Noboru,Fukuzumi, Shunichi The Royal Society of Chemistry 2010 Journal of materials chemistry Vol.20 No.15

<p>A new α-diketoporphyrin and the corresponding Pd complex were prepared from the monoanthroporphyins and their photochemical properties were investigated by measurements of absorption and emission spectra, fluorescence lifetimes, laser flash photolysis, cyclic voltammetry, and theoretical calculations. Intramolecular electron transfer from the porphyrin singlet excited state to the diketone moiety was observed for the free base α-diketoporphyrin in benzonitrile, but this was not observed in toluene. Photoreactivity of the α-diketoporphyrins was also examined by irradiation at the Soret and Q bands. When the Soret band of the freebase α-diketoporphyrin was irradiated, cleavage of the diketone moiety occurred to afford the monoanthroporphyrin with the release of two CO molecules quantitatively in both benzonitrile and toluene. When the Q band of the freebase α-diketoporphyrin was irradiated, no photocleavage reaction occurred in toluene. In contrast to the freebase α-diketoporphyrin, the photocleavage reaction of the Pd complex occurred with irradiation at the Q band as well as the Soret band to afford the monoanthroporphyrin quantitatively in toluene. The photocleavage reaction proceeded much more effectively in toluene than in benzonitrile. The occurrence of rapid photoinduced electron transfer from the singlet excited state porphyrin to the diketone moiety, which was detected by femtosecond laser flash photolysis measurements, results in a significant decrease in the singlet excited state lifetime, prohibiting the photocleavage reaction in benzonitrile. Thus, the Pd α-diketoporphyrin can act as an excellent precursor for the corresponding acene in toluene. The photocleavage process provides a convenient and inexpensive method to make the thin film.</p> <P>Graphic Abstract</P><P>A new α-diketoporphyrin and its Pd complex were prepared and successfully converted into the corresponding monoanthroporphyins by photoirradiation of the porphyrin moieties with release of two CO molecules quantitatively. <img src='http://pubs.rsc.org/ej/JM/2010/b923220f/b923220f-ga.gif'> </P>
