In this study, PSf-$Al(OH)_3$ beads were prepared by immobilizating aluminum hydroxide $Al(OH)_3$ with polysulfone (PSf). The removal experiments of the fluoride ions by PSf-$Al(OH)_3$ beads were conducted batchwise and the parameters such as pH, initial fluoride concentration, and coexisting ions were investigated. The maximum removal capacity obtained from Langmuir isotherm was 52.4 mg/g and the optimum pH region of fluoride ions was in the range of 4 to 10. The removal process of fluoride ions by PSf-$Al(OH)_3$ beads was found to be controlled by both external mass transfer at the earlier stage followed by internal diffusion at the later stage. The presence of coexisting anions such as $HCO_3{^-}$, $SO{_4}^{2-}$, $NO_3{^-}$, and $Cl^-$ had a negative effect on removal of fluoride ions by PSf-$Al(OH)_3$ beads. 본 연구에서는 폴리술폰(polysulfone, PSf)으로 알루미늄 수산화물(aluminum hydroxide, $Al(OH)_3$)을 고정화한 PSf-$Al(OH)_3$ 비드를 제조하였다. 제조한 PSf-$Al(OH)_3$ 비드에 의한 불소 이온 제거실험은 회분식으로 수행하였으며, pH, 초기농도, 공존이온과 같은 변수들의 영향을 살펴보았다. Langmuir 등온식으로 구한 불소 이온의 최대 제거량은 52.4 mg/g이었으며, 최적 pH 범위는 4~10이었다. PSf-$Al(OH)_3$ 비드에 의한 불소 이온의 제거과정은 전 단계에서 외부물질전달이 나중 단계에서 내부확산이 지배인 것을 알 수 있었다. 또한 PSf-$Al(OH)_3$에 의한 불소 이온의 제거에서 $HCO_3{^-}$, $SO{_4}^{2-}$, $NO_3{^-}$, $Cl^-$와 같은 공존 음이온들은 불소 이온의 제거에 방해를 하는 것으로 나타났다.

본 논문에서는 능동형 Q-스위칭 광섬유 레이저에서 Q-스위치 상승 시간이 출력 펄스에 미치는 영향을 이론적으로 분석하였다. Finite Difference Time Domain (FDTD) 방법을 이용해서 비율 방정식과 전파 방정식에 대한 모델링을 수행하였다. Q-스위칭 광섬유 레이저에서 발생하는 Q-스위칭 펄스의 생성에 있어서 Q-스위치의 상승 시간이 출력 펄스 특성에 미치는 영향을 이론적으로 분석하였다. 또한, Q-스위치의 반복률에 따른 출력 펄스의 에너지 변화와 파형 변화를 확인하였다. Q-스위치 반복률이 높아지고, Q-스위치의 상승 시간이 길어질수록 출력 펄스의 멀티 피크 현상이 줄어들고 안정된 가우시안 형태의 펄스 파형이 발생함을 확인 할 수 있었다. A theoretical analysis of the impact of rise time of a Q-switch on the output pulse performance is carried out in an Ytterbium-doped actively Q-switched fiber laser. The finite difference time domain (FDTD) method is used to numerically simulate the Q-switched fiber laser. It is shown that stable Gaussian-like pulse shape can be generated when the Q-switch rise time is increased and pulse repetition rate is enlarged.

The photocatalytic decomposition characteristics of toluene, acetone, and methyl mercaptan (MM) by UV reactor installed with TiO2-coated perforated plane were studied. The removal efficiency of single toluene, acetone, and MM vapor was increased with increasing oxygen concentration, but decreased with increasing inlet concentration. Elimination capacity of single toluene, acetone, and MM vapor was obtained to be 628 g/m3;day, 1,041 g/m3;day, and 2,158 g/m3;day, respectively. Also, the photocatalytic decomposition of binary vapor consisted of toluene and acetone, toluene and MM, acetone and MM were observed. Elimination capacity of toluene mixed with acetone, toluene mixed with MM, acetone mixed with toluene, acetone mixed with MM, MM mixed with toluene, and MM mixed with acetone was 327 g/m3;day, 512 g/m3;day, 128 g/m3; day, 266 g/m3;day, 785 g/m3;day and 883 g/m3;day, respectively. The inhibitory effect of acetone was higher than MM in photocatalytic decomposition of toluene, the inhibitory effect of toluene was higher than MM photocatalytic decomposition of acetone, and the inhibitory effect of toluene was higher than acetone in photocatalytic decomposition of MM.

This research analyzed correspondence effort what the hospital cope with, relation of fairness sensation, fairness and customer satisfaction which is perceived by service recovery, perceived value, hospital image and influencing relationship of future behavior intention to recover service failure. In result of the research, refund and discount among the hospital correspondence effort have a most effect on distribution fairness. This means customers show most positive response about typical output of service recovery strategy. Also, we can know importance of policy, process, tools to support customer`s complain and hospital swift response. Apologize and explanation influences to mutual relation fairness perception positively. Here is intriguing result. procedural justice in contrary with distributive justice and interactional justice doesn```t have a positive affect to perceived value. In other words, typical reward and heartfelt apologize and explanation has positive affect to perceived value, perceived value of policy, process, tools used by decision maker doesn``t have positive affect to customer`s perceived value. On the other hand, customer`s perceived value and satisfaction about perceived justice through service recovery has a positive affect to hospital image, this hospital image has positive affect to future behavior intention. There were multiple researches that can be used for all sorts of things. But, the research for hospital was insufficient. What is important is that we draw an objective research conclusion considering that hospital is one of the service company. Also, in case of medical service failure, it can be used for reference about service recovery method that customers want, and it can be helpful to improvement of medical service quality.

This paper aims at developing and applying open-BIM tailored to Korea’ traditional wooden architecture under the following process: a) adoption and application of the correlation between Korea’s traditional wooden architecture into open-BIM classification scheme, b) development of classification system and code suitable for Korea’s traditional wooden architecture and c) assessment of its validity. The sample used for the assessment of the classification code is Bongjeong Temple of Korea. The results verify that under the developed system application into the traditional wooden architecture, the majority of previous impediments to BIM application are removed, thus putting forward the future research direction for advancement along with the current status of research.
