An automatic modal identification program is developed for continuous extraction of modal parameters of three cable-supported bridges in Hong Kong which are instrumented with a long-term monitoring system. The program employs the Complex Modal Indication Function (CMIF) algorithm for identifying modal properties from continuous ambient vibration measurements in an on-line manner. By using the LabVIEW graphical programming language, the software realizes the algorithm in Virtual Instrument (VI) style. The applicability and implementation issues of the developed software are demonstrated by using one-year measurement data acquired from 67 channels of accelerometers permanently installed on the cable-stayed Ting Kau Bridge. With the continuously identified results, variability in modal vectors due to varying environmental conditions and measurement errors is observed. Such an observation is very helpful for selection of appropriate measured modal vectors for structural health monitoring use.

There is an important concern regarding the First-line nurse manager's leadership because of the recognition that effectiveness of Leadership in this position results in benefits for the whole health care organization. So knowledge and practice of effective leadership behavior are now more essential to nursing than ever before. First-line Nurse Managers must be effective leaders to meet today's challenge because staff nurse, patient are affected by them. So the purpose of this study was to identify and to analyse the need for Leadership program of First-Line nurse managers in university hospitals. There were three major purposes of this study. First, identify First-line nurse managers general characteristic, second, identify their experience of leadership training, third, identify and analysis their demands for leadership training program. The subjects for this study was 167 First-line nurse manager randomly from 18 university hospitals in Korea. The data were collected through questionnaires from Oct. 13th to Nov. 20th, 1997, data was analysed using frequencies and percentages. Especially the steps of analysis of descriptions were as follows: Initial analysis centered on the identification of the demands of first-line nurse managers. Later analysis collapsed the demands into broad categories. From the collect data, 283 demands of first-line nurse managers were identified. These demands were then sorted into 3 broad categories that included : Self development as first-line nurse managers, relationship with others, and practice. The result of the study were as follows ; 1) Most of nurse managers(79.6%) had leadership training course and had good experience to improve self leadership. 2) Their demands of leadership training course are as follows First, for self as first-line nurse managers, they want to learn leadership theory, identify their leadership style and then develop their leadership skill. Second, for others as first-line nurse managers, they want to improve their communication skill, empowering others, relationship with others. Third, for patients as first-line nurse managers, improve their knowledge of practice. From the above finding, this study can be suggested the following; 1. Develope a leadership training course to improve first- line nurse manager's leadership skill according to their demands, so they will be better able to lead staff nurses for organization purposes. 2. When develope leadership training program, it must be contained the factors which first-line nurse managers want to learn.

A spectral line survey is performed from 159.7 to 164.7 GHz toward Orion-KL, as an extension of our previous line survey from 138.3 to 150.7 GHz with the same 14 m radio telescope of Taeduk Radio Astronomy Observatory. Typical system temperatures were 260 - 1000 K to achieve a sensitivity of about 0.02 - 0.04 K in TA unit. A total of 63 line spectra are detected in this survey. Among them, 54 lines lines are found to be the first detections towards an astronomical source and only 9 spectral lines have been previously identified from other observations. Forty-eight of 54 lines are believed to be from the known transitions of the known molecules, while 6 lines are 'unidentified'. All detected lines are found to be from a total of 10 molecular species and their isotopic variants. The molecular species with most numerous detected transitions are $HCOOCH_3$ (22), followed by $CH_3OCH_3$ (7), $C_2H_5CN$ (7), and $SO_2$ (6). The LTE rotation diagram analysis using all homogeneous data with those from previous survey gives more reliable determination of physical quantities. The derived values of the rotation temperatures and column densities for $HCOOCH_3$, $CH_3OCH_3$, and $SO_2$ are are 75 $\~$ 197 K and $1.5 {\~}18 {\times} 10^{15}\;cm^{-2}$, respectively.

Consumer expectations for ethical businesses have become increasingly high in recent years; the fashion industry is working to implement greater corporate social responsibility (CSR). This study establishes the effects of the evaluation for participation in fashion brand CSR on perceived purchase values. In particular, the process for the evaluation for participation that affect the perceived purchase value through consumer-brand identifications (personal/social) was verified and how the consumer regulatory focuses would influence this process was identified. For this study, an on-line survey was conducted that included a series of filtering questions that measured the level of social concern of respondents. Valid data from 505 female consumers were analyzed for the structure equation modeling. The empirical results suggested that the evaluation for participation in fashion brand CSR positively affected the two dimensions of consumer-brand identification; personal identification and social identification. In addition, consumer-brand identification played a role as a mediating variable in the path to influence the perceived purchase values of CSR brands. Lastly, there were differences in reactions to CSR activities by consumer groups with different regulatory focuses. The effect of the evaluation for participation in fashion brand CSR was shown to be higher for consumers with promotion focuses than on consumers with prevention focuses. The results of this study will help fashion companies understand the importance of the consumer participation in CSR by having consumers participate in ethical consumption.

Objective: This in-vivo study aimed to compare landmark identification errors in anteroposterior (AP) and posteroanterior (PA) cephalograms generated from cone-beam computed tomography (CBCT) scan data in order to examine the feasibility of using AP cephalograms in clinical settings. Methods: AP and PA cephalograms were generated from CBCT scans obtained from 25 adults. Four experienced and four inexperienced examiners were selected depending on their experience levels in analyzing frontal cephalograms. They identified six cephalometric landmarks on AP and PA cephalograms. The errors incurred in positioning the cephalometric landmarks on the AP and PA cephalograms were calculated by using the straight-line distance and the horizontal and vertical components as parameters. Results: Comparison of the landmark identification errors in CBCT-generated frontal cephalograms revealed that landmark-dependent differences were greater than experienceor projection-dependent differences. Comparisons of landmark identification errors in the horizontal and vertical directions revealed larger errors in identification of the crista galli and anterior nasal spine in the vertical direction and the menton in the horizontal direction, in comparison with the other landmarks. Comparison of landmark identification errors between the AP and PA projections in CBCT-generated images revealed a slightly higher error rate in the AP projections, with no inter-examiner differences. Statistical testing of the differences in landmark identification errors between AP and PA cephalograms showed no statistically significant differences for all landmarks. Conclusions: The reproducibility of CBCT-generated AP cephalograms is comparable to that of PA cephalograms; therefore, AP cephalograms can be generated reliably from CBCT scan data in clinical settings.

As well known when the linear machine is operated between two points repeatedly under positioning control, there are various positioning error at the moment of zero speed owing to the non-linear disturbance like as unpredictable friction force. To remove this positioning error, a simple least order disturbance observer is introduced and is actually implemented in this study. Due to this simple algorithm the over-all machine system can be modified to simple arbitrary given one-mass load without any disturbance. So, the total construction process for positioning control system is much easier than old one. Moreover, to generate a proper effective position profile with the limited actual machine force, a very powerful on-line mass identification algorithm using the load force estimator is presented. In the proposed mass identification algorithm, the exact load mass can be calculated during only one moving stage under a normally generated position profile. All presented algorithm is verified with experimental result with commercial linear servo machine system.
