Purpose : To evaluate effects of McKenzie exercise on the functional recovery and forward head posture of chronic neck pain patients. Methods : The subjects were consisted of fifteen patients who had abnormal neck posture, mild neck pain (28 males, 17 females; mean aged 21.9) from 19 to 33 years of age(mean age 21.9). All subjects were received McKenzie exercise for 35 minutes with clinical massage per day three times a week during 4 weeks period. Neck disability index was used to measure functional disability level. Visual analogue scale(VAS) was used to measure subjective pain level. craniovetebral angle(CVA), cranial rotation angle(CRA) was used to measure forward head posture with digital camera. All measurements of each patients were measured at pre-treatment and after 2 week, after 4 week, post-treatment on 2 week. Result : The VAS of McKenzie exercise was significantly reduced between pre-treatment and post-treatment (p<.05) and effects of pain reduce was continued follow 2 weeks. The Neck Disability Index of McKenzie exercise was significantly reduced between pre-treatment and post-treatment (p<.05) and effects of pain reduce was continued follow 2 weeks. The CVA of McKenzie exercise was significantly reduced between pre-treatment and post-treatment (p<.05) and effects of pain reduce was continued follow 2 weeks. The CRA of McKenzie exercise was not significantly reduced between pre-treatment and post-treatment (p<.05). Conclusion : McKenzie exercise improved pain and function of Chronic neck pain patients.

We have investigated the effects of hydrogen injection via in-situ gas addition ($O_2$, $H_2$, or $O_2$ + $H_2$ gas) and plasma post-treatment (Ar or Ar + H plasma) on material properties of ZnO that is considered to be as a channel layer in transparent thin film transistors. The variations in the electrical resistivity, optical transmittance and bandgap energy, and crystal quality of ZnO thin films were characterized in terms of the methods and conditions used in hydrogen injection. The resistivity was significantly decreased by injection of hydrogen; approximately $10^6\;{\Omega}cm$ for as-grown, $1.2\;{\times}\;10^2\;{\Omega}cm$ for in-situ with $O_2/H_2\;=\;2/3$ addition, and $0.1\;{\Omega}cm$ after Ar + H plasma treatment of 90 min. The average transmittance of ZnO films measured at a wavelength of 400-700 nm was gradually increased by increasing the post-treatment time in Ar + H plasma. The optical bandgap energy of ZnO films was almost monotonically increased by decreasing the $O_2/H_2$ ratio in in-situ gas addition or by increasing the post-treatment time in Ar + H plasma, while the post-treatment using Ar plasma hardly affected the bandgap energy. The role of hydrogen in ZnO was discussed by considering the creation and annihilation of oxygen vacancies as well as the formation of shallow donors by hydrogen.

The aim of the present study was to develop a cognitive-behavioral group therapy program for social anxiety in Korean adolescents and to examine its efficacy through pre-, post- and 2-year follow-up tests. The program included cognitive restructuring, exposure training and social skills training. KSAS-A and SASC-R were administered to 588 1st grade middle-school female students to assess their social anxiety levels. On the basis of double criteria procedure(top 10% scores on both scales), 59 students were selected initially. Individuals currently receiving clinical treatment were excluded. Finally, 40 students were selected and randomly assigned to either a treatment group or a wait-list control group. The program consisted of 12 weekly sessions, approximately 1.5-2 hours in duration. Whereas pre- and post-tests were administered to both groups, follow-up tests were administered to the treatment group only. The collected data were statistically analyzed through independent t-test and paired t-test. The results of the study were as follows: 1) At post-test students in the treatment group showed a very significant reduction in social anxiety and fear of negative evaluation by others in comparison with those in the wait-list group. 2) At post-test students in the treatment group showed a significant reduction in negative automatic thoughts in comparison with those in the wait-list group. 3) At post-test students in the treatment group showed a significant improvement in overall social skills in comparison with those in the wait-list group. 4) At post-test students in the wait-list group showed a significant increase in both social anxiety and negative automatic thoughts in comparison with those in the treatment group. 5) At 3-month, 1-year and 2-year follow-ups, the program's effectiveness was maintained.

A novel two-step surface treatment was developed and demonstrated for the carbon nanotube (CNT) cathode with highly efficient backlight unit application. An adhesive taping method was applied firstly and then followed by a post-heat treatment for the CNT cathode. During the postheat treatment process, some residues covering the CNTs were burned out. The post-heat treatment enhanced the emission current of the CNT cathode around 20% compared with that of no heat-treated sample.

A great number of moment-resisting steel structures collapsed due to ductile crack initiation at welded beam-column connections, followed by explosive brittle fracture in the Kobe (Hyogoken-Nanbu) earthquake in 1995. A series of experimental and numerical studies on cracking behaviors of beam-column connections in steel bridge piers were carried out by the authors' team. This paper aims to study the effect of post weld treatment on cracking behaviors of the connections during a strong earthquake event. Experiments of three specimens with different weld finishes, i.e., as-welded, R-finish, and burr grinding, were conducted. The experimental results indicate that the instants of ductile crack initiation are greatly delayed for the specimens with R-finish and burr grinding finishes compared with the as-welded one. The strain concentration effect in the connection is also greatly reduced in the specimens with post weld treatment compared with the as-welded one, which was also verified in the tests.
