  • This study was designed to determine the schemata and their characteristics of stress experience the subjectivity of stress experience(structure of subjectivity) would be a basic step for the effective clinical education through the stress management for characteristics of these types. Q-methodological method was used for that purpose. The research method statements were collected prior to the study through indepth interviews. For the study, 31 Q-statements were selected. There were 34 nursing students as subjects for the research. The 34 nursing students sorted the 31 statements using the principal of forced normal distribution. The principle of forced normal distribution, which has 9 scales to measure the individual opinions, was called. Q-factor analysis by using PC QUANL program supply the material. According to the outcomes of this study, there were 3 types of special opinion about the stress experience of clinical practice. The first type is called 'Influence of practical atmosphere type'. Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The second type is called 'conflict of nursing role type'. Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The third type is called 'Lack of confidence type'. Members of this type experienced stress because of a lack of confidence for their own nursing knowledge and skill. As a result, we now need further study to identify individual psychological aspects of stress for clinical practice. The findings will guide the development in effective approaches for clinical education. Finally, the result of the study will provide us the need for developing systematic and integrated practice education program for students and active involvement of clinical instructor.

  • A poly(1-hexyl-3,4-dimethyl-2,5-pyrrolylene) (PHDP) was prepared and its luminescence in tetrahydrofuran (THF) was studied. When PHDP is excited by UV light, it produces very strong blue luminescence. The quantum yield of PHDP (Q = 36.9%) is much greater than that of the monomer, 1-hexyl-3,4-dimethylpyrrole (HDP) with Q = 0.61%. The principal luminescence of PHDP has a single decay component with ca. 1 ns, whereas the decay of HDP is complicated. The molecular structure and conformational behavior of HDP and the oligomers up to trimer have been also determined by ab initio Hartree-Fock (HF/6-31$G^{**}$), density functional theory (DFT-B3LYP/6-31$G^{**}$), and semiempirical (ZINDO) methods. According to the results of calculations, it is proposed that the enhanced quantum yield of the polymer PHDP results mostly from the ${\pi}$-conjugation between neighboring pyrrole rings.

  • The objective of this study is to provide pollutant loads delivery ratio for flow duration in Oenam-cheon watershed, which is upstream watershed of Juam Lake. To calculate the delivery ratio by flow duration, rating curves and discharge-loads curves using measured data were established, then Flow Duration Curve(FDC) and pollutant loads delivery ratio curves were constructed. The results show that the delivery ratios for $BOD_5$ for abundant flow($Q_{95}$), ordinary flow($Q_{185}$), low flow($Q_{275}$), and drought flow($Q_{355}$) were 23.9, 12.7, 7.1, and 2.9%, respectively. The delivery ratios of same flow regime for T-N were 58.4, 31.2, 17.2 and 7.1%, respectively. While, the delivery ratios T-P were 17.3, 7.5, 3.4, and 1.1% respectively. In general, delivery ratio of high flow condition showed higher value due to the influence of nonpoint source pollution. Based on the study results, generalized equations were developed for delivery ratio and discharge per unit area, which could be used for ungaged watershed with similar pollution sources.

  • The heat distribution in crystals in a 2-㎛ acousto-optic Q-switched Tm:LuAG laser pumped by pulsed-laser-diode (pulsed-LD) intermittent-pumping technology was analyzed using COMSOL software. The thermal lensing effect of the Tm:LuAG crystal can be mitigated by pulsed-LD intermittent-pumping techniques. An experimental setup using this kind of approach achieved maximum output energy of 8.31 mJ, minimum pulse width of 101.9 ns, and highest peak power of 81.55 kW, reached at a Q-switched repetition rate of 200 Hz. It offers significant improvement of performance of the output laser beam, compared to pulsed-LD double-ended pumping technology at the same repetition rate.

  • Decay rate and nutrient dynamics during leaf litter decomposition of deciduous Quercus acutissima were compared between Gongju and Jinju for 33 months from December 2008 through March 2011. Percent remaining weight of Q. acutissima leaf litter after 33 months elapsed in Gongju and in Jinju was $41.2{\pm}0.4%$ and $28.3{\pm}0.6%$, and decay constant (k) was 0.39 and 0.61, respectively. Decomposition in Jinju was significantly faster than that in Gongju. This seemed to be related to higher temperature and precipitation in Jinju than those in Gongju during the experimental period. Initial C/N and C/P ratio of Q. acutissima leaf litter was 46.8 and 270.9, respectively. After 33 months elapsed, C/N and C/P ratios in Gongju decreased to 22.0 and 106.8, and those in Jinju decreased to 19.2 and 170.2, respectively. Initial concentration of N, P, K, Ca and Mg in Q. acutissima leaf litter was 8.31, 0.44, 4.18, 9.38, 1.37 mg/g, respectively. After 33 month elapsed, remaining N, P, K, Ca and Mg were 91.0, 85.4, 30.2, 47.9, 11.7% in Gongju, and 67.0, 54.2, 19.9, 30.0, 40.8% in Jinju, respectively. Except for Mg, remaining nutrients of decomposing leaf litter in Jinju were lower than those in Gongju. In case of N and P, initial immobilization was observed, however, only mineralization was observed in K, Ca and Mg during the whole experimental period.

  • The present study was intended to measure the level of fatigue symptoms among nurses working for a university hospital and to reveal its related factors. The self-administered questionnaires were given to 450 nurses during the period from October 1st to 31st, 2010. As a results, the level of fatigue symptoms were 75.1% in normal group, and the high-risk group 24.9%. The level of fatigue symptoms reflected in job stress contents were higher as job demand was higher, and the autonomy of job and the supervisor support was lower. In correlations, fatigue symptoms were found to be in a positive correlation with job demand, whereas in negative correlation with autonomy of job and supervisor support. The adjusted odds ratio of fatigue symptoms on job demand were significantly increased in the high risk group than in low group, but autonomy of job. were significantly decreased in the high risk group than in low group. In conclusion, the study results indicated that the level of fatigue symptoms is independently influenced by job stress contents.
