Chronotype (CT) is defined as an inter-individual difference in sleep-wake cycles and daily activities. Previous studies have suggested that this individual difference can influence our biological and psychological functioning. Literature regarding the psychometric properties and validity of CT measures are reviewed. We provide an overview of biological indicators (sleep-wake cycle, body temperature, cortisol, and melatonin) that are used for distinguishing two chronotypes: morningness (MT) and eveningness (ET). We also review the differences between CT in relation to personality traits and the occurrence of psychopathology. In addition, the methodological limitations of studies on CT are discussed. Finally, future research directions in terms of CT are proposed.

Purpose: This study aimed to develop and test a structural model for chemotherapy-related cognitive impairment of breast cancer patients based on a literature review and Hess and Insel's chemotherapy-related cognitive change model. Methods: The Participants consisted of 250 patients who were ${\geq}19$ years of age. The assessment tools included the Menopause Rating Scale, Symptom Experience Scale, Hospital Anxiety and Depression Scale, Everyday Cognition, and Functional Assessment of Cancer Therapy-Breast Cancer. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs. Results: The modified model was a good fit for the data. The model fit indices were ${\chi}^2=423.18$ (p<.001), ${\chi}^2/df=3.38$, CFI=.91, NFI=.91, TLI=.89, SRMR=.05, RMSEA=.09, and AIC=515.18. Chemotherapy-related cognitive impairment was directly influenced by menopausal symptoms (${\beta}=.38$, p=.002), depression and anxiety (${\beta}=.25$, p=.002), and symptom experiences (${\beta}=.19$, p=.012). These predictors explained 47.7% of the variance in chemotherapy-related cognitive impairment. Depression and anxiety mediated the relations among menopausal symptoms, symptom experiences, and with chemotherapy related cognitive impairment. Depression and anxiety (${\beta}=-.51$, p=.001), symptom experiences (${\beta}=-.27$, p=.001), menopausal symptoms (${\beta}=-.22$, p=.008), and chemotherapy-related cognitive impairment (${\beta}=-.15$, p=.024) had direct effects on the quality of life and these variables explained 91.3%. Conclusion: These results suggest that chemotherapy-related toxicity is highly associated with cognitive decline and quality of life in women with breast cancer. Depression and anxiety increased vulnerability to cognitive impairment after chemotherapy. Nursing intervention is needed to relieve chemotherapy-related toxicity and psychological factor as well as cognitive decline for quality of life in patients undergoing chemotherapy.

Objectives: The purpose of this study was to provide clinical evidence to support the use of herbal medicine combined with western medicine for BPSD. Methods: Studies were identified by searching CNKI, Pubmed, EMBASE, Cochrane Library, SCIENCEON, RISS, KMbase, KISS, OASIS. Literature searches of Chinese, English, and Korean databases were performed. Two authors independently extracted the data and evaluated the quality of each study. Results: The literature search identified 203 articles. Of these, 7 were selected for the analysis. The risk of bias in most studies was unclear. The most frequently used diagnostic tools were the NINCDS-ADRDA and DSM-IV. The most commonly used results indicator was NPI. In 6 of the 7 papers, combination treatment (herbal & Western medicine) was statistically significantly more effective than single treatment (Western medicine alone) for BPSD. No significant adverse events were reported. Conclusions: Herbal medicine in combination with Western medicine is more effective for treating BPSD than Western medicine alone. However, the quality of the studies used in this study was uncertain and the sample size was too small. Based on the findings of this study, more high-quality clinical trials are needed to confirm the efficacy of combination treatment.

While carpal tunnel syndrome (CTS) is the most common entrapment neuropathy affecting the wrist, resulting in substantial physical, psychological, and economic effects, there is no gold standard therapy for CTS. In this case series study, we aimed to report CTS patients treated with Carthami Semen Pharmacopuncture (CSP) and electroacupuncture (EA) showing improvements in their symptoms, and the combinatorial effects of CSP and EA. We collected medical records of CTS outpatients who received CSP and EA at Chuku Acupuncture & Moxibustion Korean Medicine Clinic from August 2017 to September 2018. The outcome measures were the visual analog scale (VAS) for pain, paresthesia, the Korean version of the Boston carpal tunnel questionnaire (K-BCTQ) score, and changes in nocturnal pain, Tinel sign, and Phalen's test. We included patient satisfaction at the completion of all treatments. 17 patients were included for this case series study. After treatment, VAS for pain decreased significantly from 50.41 ± 16.19 to 9.59 ± 9.46, VAS for paresthesia also decreased significantly from 63.50 ± 11.49 to 14.75 ± 12.97, and K-BCTQ symptom severity scale decreased from 2.48 ± 0.68 to 1.89 ± 0.70 (all p < 0.001). Nocturnal pain, Tinel signs, and Phalen's test showed improvements after all the treatments. All the patients reported favorable overall satisfaction with the treatments, and 69.23% wanted future pharmacopuncture treatments if CTS recurred. No complications were detected. The combination of CSP and EA could be an effective and safe option in treating CTS.

Bullying at school results in a variety of psychological and social issues. Even after victims reach adulthood, these issues do not resolve and can have detrimental effects. The purpose of this study is to explore the effect of school bullying victimization on body appreciation in adulthood. Considerations include multi-mediating effects of physical attractiveness comparison and ambivalent emotions toward beauty. A research model comprised of six hypotheses was derived applying the A (adversity)-B (belief)-C (consequence) theory. A survey with 583 South Korean women in their twenties to forties was conducted to collect data. Confirmatory factor analysis, structural equation modeling, and multi-mediation analysis were applied, and all hypotheses were accepted. School bullying victimization had a negative influence on body appreciation in adulthood. Additionally, physical attractiveness comparison and ambivalent emotions toward beauty mediated this causal relationship. Also, the mediating effect of physical attractiveness comparison on the relationship between school bullying victimization and body appreciation was the greatest among the three mediating effects. This study demonstrated that bullying victimization at school continues into adulthood, which hurts body appreciation of adulthood. The findings would contribute to the development of therapy programs for school bullying victims.

α-pinene is a natural volatile organic compound secreted by coniferous trees to protect themselves from attacks by insects, microorganisms, and viruses. Recently, studies have reported that α-pinene possesses pharmacological effects on various biological reactions such as anxiolytic, sleep-enhancing, anti-nociceptive, and inflammatory activity. Thus, forest bathing has recently received great attention as a novel therapy for treating severe diseases as well as psychological issues. However, appropriate places and timings for effective therapies are still veiled, because on-site monitoring of α-pinene gas in forests is barely possible. Although portable chemosensors could allow real-time analysis of α-pinene gas in forests, the α-pinene sensing properties of chemosensors have never been reported thus far. Herein, we report for the first time, the α-pinene sensing properties of an oxide semiconductor gas sensor based on rhombohedral In₂O₃ (h-In₂O₃) nanoparticles prepared by a microwave-assisted hydrothermal reaction. The h-In₂O₃ nanoparticle sensor showed a high response to α-pinene gas at ppm levels, even under humid conditions (for example, relative humidity of 50 %). The purpose of this research is to identify the potential of oxide semiconductor gas sensors for implementing portable devices that can detect α-pinene gas in forests in real-time.

Purpose: The purpose of this study was to explore the effects of abdominal breathing on relieving anxiety in women diagnosed with preterm labor. Method: This was a pilot study, which was based on a repeated pre-post experiment design without a control group. Seven patients with preterm labor who were admitted to Y university medical center, Seoul, Korea, participated in the experiment. They were under receiving ritodrine hydrochloride(Yutopa) as tocolytic therapy and did not have any other complications. The patients were taught abdominal breathing, which is a modified version of Mason's breathing technique. The experimental treatments were done 33 times from February 18 to June 19 in 2005. Result: After abdominal breathing, the average psychological anxiety level decreased significantly. The physical anxiety levels of preterm labor patients were measured by blood pressure, pulse, and skin temperature. After abdominal breathing, the average systolic and diastolic blood pressure decreased from 117.3mmHg to 107.6 mmHg (z=-3.85, p<.001) and from 67.3mmHg to 62.7 mmHg (z=-3.14, p<.005), respectively. The average pulse rate also decreased from 97.2/min to 89.8/mim (z=-4.76, p<.001). The average skin temperature increased from 94.0 to 94.9(z=-4.80. p<.001). Conclusion: Abdominal breathing is effective for relieving anxiety of women diagnosed with preterm labor. This study, however, has been limited to short-term effects, and therefore further studies are required in order to examine the long-term effects of abdominal breathing.

Lately in the medical world, they realized that the spirit is important for health best of all, and in the WHO, the meaning of health was "The condition of being sound in body, mind", now as they added the spirit to there, it became "The condition of being sound in body, mind, or spirit". Even though we know well about the importance of spirit, but it is difficult to make sure what that mean is. Even in the Psychology, they didn't distinguish clearly the spirit from the mind. In this report, we have revealed the traits of spirit from the classic theory of spirit to the today's, as studying at side of biology and psychology. Especially the spirit have been developed remarkably for a long time at every religion. Recently in the medical world, they connected 'the spirit of Buddhism' to 'MBSR', and 'the spirit of Christianity' to 'Breakout Principle' with medical method. So, we have studied how the spirit give the positive contribution to the Psycho-therapy.
