This study was conducted to examine the effects of wound dressing with thiophanate-methyl paste on the compartmentalization of pruning wounds in Acer palmatum. A total of thirty field-grown trees were used for three different treatments, such as no dressing, dressing once right after pruning cut, and dressing twice, one more dressing treatment one year after initial dressing. Wound closure rate (WCR) and discolored/wound area ratio (D/W ratio) two years after treatment were measured. Variations of extractives, holocellulose and lignin at the treated branch unions were also examined. The WCR of no dressing treatment of 70.9% was significantly lower than those of the two dressing treatments (85.4% and 82.7%, respectively), while the difference between dressing once and twice was not significant. The D/W ratio of no dressing treatment (39.3%) was significantly higher than those of the two dressing treatments (around 30%). Generally, at the branch core of the treated union, contents of extractives and lignin were higher and holocellulose contents were lower than the branch core of the union with living branch. Among the branch core of treated union, no dressing treatment showed a relatively lower holocellulose (63.5%), and relatively higher extractives (2.8%) and lignin (26.6%) than dressing once (66.2%, 1.7%, 26.1%, respectively).

The optimum RRA heat treating conditions and SCC (stress corrosion cracking) resistance of semi-solid Al-Zn-Mg-Cu alloy fabricated by inclined cooling plate were compared with those of conventional mould cast alloys. The non-stirring method characterized by using a cooling plate can effectively eliminate dendritic structure and form a fine globular semisolid microstructure in as-cast Al-Zn-Mg-Cu alloy and the SCC resistance of semi-solid Al-Zn-Mg-Cu alloy was higher than that of conventional mold cast alloy. Also, after retrogressed treatment at RRA heat treatment of semi-solid Al-Zn-Mg-Cu alloy, retrogressed treatment time has increased more than 10 minutes at $180^{\circ}C$ to recovery the T6 heat treatment strength.

Objectives The purpose of this review is to investigate the clinical studies of oriental treatment for Autism in China and seek the better methods to study and treat Autism in Korea. Methods We searched for the study at CNKI by keywords, 'Autism', '孤獨症', '自閉症', in the last 5years. Results Selected 14 clinical studies were divided into 6 case reports and 8 control studies. The subjects of clinical study were the average 4-9 years old children. It was described that the symptoms were improved after treatment in 6 case reports. 8 control studies reported that the experimental group were better effective than the comparison group. Frequently used method for treatment was Scalp acupuncture. Conclusions It is promising that we could develop our own treatment and studies for autism in Korea by using Scalp acupuncture, based on these clinical studies.

Objectives: The purpose of the study was to investigate the influencing factors on anxiety and depression before and after prosthetic treatment in the patients. Methods: A self-reported questionnaire was completed by 248 patients with tooth loss and over 20 years old. The questionnaire was carried out before and after oral examination and dental prosthetic treatment from July to December, 2013. The study instruments included Beck's anxiety inventory and self-rating depression scale by Zung. The questionnaire was adapted and modified from Kwon's anxiety inventory and Lee's depression scale. Results: While the anxiety level increased from 69.4% to 78.2% in the normal people, the depression level changed from 53.2% to 64.1% in the normal people. The gender variable had a positive effect on anxiety and depression while educational level had a negative effect on them. The dental fear was closely related to anxiety and depression before and after the prosthetic treatment. The entire body health perception showed a negative effect on anxiety and depression. The distrust towards the dentist had an influence on the anxiety and depression in the prosthetic patients. Conclusions: The influencing factors on anxiety and depression in the prosthetic patients included gender, dental fear, entire body perception, and distrust towards the dentist.

Objectives: This study was performed to review the research trends in the treatment of panic disorder in traditional Chinese medicine (TCM). Methods: We searched articles in the China National Knowledge Infrastructure (CNKI) from 2004 to 2014. Search key words were '惊恐' and 'panic disorder', and we selected eight studies except for non-clinical, unrelated studies, tests on animals. Results: We finally selected eight articles, and the results were as follows. CCMD-3 was most frequently used as a diagnostic criterion and HAMA was mostly used for outcome measurement. In TCM there are various ways, such as herbal medicine, acupuncture and psychotherapy, to treat panic disorder. Most of the studies showed effective results. Most of the treatment group reported that they had less side effects than the control group. However, the quality of these clinical studies was low. Conclusions: In TCM, research on panic disorder was being conducted more actively than in Korean medicine. According to this study, it seems that in TCM, the treatment of panic disorder might be more effective and have some advantages. Therefore, with this study, we hope to activate more clinical research on the treatment of panic disorder in Korean medicine.

A new boundary treatment technique which can be applied to axi-symmetric topography with inclined bottom was developed. Although the finite element method is good for complex geometry, there is no proper boundary treatment when a boundary is not a vertical section because the water depth at the coastline becomes zero. In this study, we developed a new boundary treatment for inclined bottom using the analytical solution for long wave. To develope a model, the mild-slope equation was used and then, a computational domain is divided into an analytical region and a numerical region. By combining a numerical and an analytical solutions, a complete solution was obtained. The developed solution was validated by comparing with a previous analytical solution.

In this study, effects of kneading treatment on the properties of hardwood bleached kraft pulp (HwBKP), softwood bleached kraft pulp (SwBKP) and hardwood bleached chemi-thermo-mechanical pulp (HwBCTMP) were elucidated with a laboratory two-shaft kneader. Kneading treatment was performed at 30% (w/w) of pulp concentration and the number of passes through the kneader was adjusted from 0 to 10 passes. Then, changes in properties of pulp fibers were evaluated. It was found that fiber characteristics were influenced by kneading treatment. Fiber length was decreased with kneading while other morphological properties such as fiber width, curl and kink became increased as the number of passes through the kneader increased from 0 to 5 passes. The magnitude of changes in the morphological properties of softwood chemical pulp was the largest, followed by hardwood chemical pulp. The morphological properties of HwBCTMP were little influenced by kneading treatment. Swelling of fiber measured by WRV was increased with kneading except of HwBCTMP.

Carbide precipitation and dissolution behavior at various temperatures during heat treatment has been studied in STD11 cold working die steel through confocal scanning laser microscopy; dilatometry; and X-ray diffraction analysis. The equilibrium phase diagram and phase fractions with temperature were calculated using a FactSage program. Confocal laser microscopic observation revealed that ${\alpha}$ to ${\gamma}$ transformation temperature is near $800^{\circ}C$; M7C3 carbides melt at $1245^{\circ}C$; and the melting temperature of STD11 is near $1370^{\circ}C$. XRD results indicated that the M23C6 carbides dissolve in the matrix if austenitized at over $1030^{\circ}C$; while the M7C3 carbides remain up to $1200^{\circ}C$ although their amount decreases. The calculated equilibrium phase diagram showed good agreement with experimental results on carbide dissolution and phase transformation temperatures.
