This study is to analyze the research rends centering on the theses related to CAT released in nursing of Korea. Method: The researcher collected the academic degrees and theses published on the book of the academic society from 1980 to 2001, and examined 88 domestic dissertations on nursing science of the CAT. Result: 1) By department, the results were: the nursing thesis 88(43.3%), medical field 45(22.1%), psychologyㆍconsulting education 28(14%). 2) In the type of the CAT in nursing, the results were: acupressure 28(31.5%), Dan-Jeon Breathing 14(15.7%) aroma therapy 5(5.6%) in order. 3) The number of theses increase every year after 1997. 4) As for the type of study design, the results were: the experimental research had the most(47), and the survey research(30). 5) As for the subject, the results were: patients with disease(44), healthy adults(29), literate(9) and medical staff were only 6 theses. 6) in the theme of the theses, the results were: the effect of therapy(76), the experience of therapy(26), adaptation of nursing of therapy(11) and literature reviews were 7. Conclusion: More research needs to be encouraged in the unsatisfactory fields. Researches should be conducted to extend into the practical fields as Korea nursing mediation, project for the establishment of health polices should be conducted.

Polusulfone scintillation proximity membranes of a double-layered structure wereprerared with Cerium Activated Yttrium Silicate (CAYS) impregnated in a membranestructure. Using the prepared membranes, the radioactivity of an area contamintedby radionuclids can be monitored without any scintillation cocktail The membranewere fromed through two separate casting and coagulation processes. The transparentand dense support layer was obtained by solidifying a polysulfone-methylene chloridebinary solution through vacuum. CAYS-dispersed polymer solutions were cast over the top of solidified, transparent polymer films and coagulated by immersing into acoagulation bath, containing either water or isopropanol. The prepared membranesconsist of double layers. The bottom laver is a dense. pure polymer film. and thetop works as an active layer to detect a radioactive contamination .The membrane structures are significantly different depending on the nonsolvent type.

The purpose of this study is to estimate wet deposition flux and to investigate wet deposition characteristics by using the ADOM model. Wet deposition flux of high reactive SO_2 is estimated by applying observed meteorological parameters and concentrations of chemical species to the ADOM model. Wet deposition is largely dependent on large scale precipitation and cloud thickness. Wet deposition flux of sulfate increases, but wet deposition flux of SO_2 is small. On the whole, the pattern of sulfate flux agrees with the typical pattern of sulfate wet deposition that is high in the summer(July) and low in the winter(January)

It has been researched the relationship between deposition velocity and factors which could affect the deposition phenomena and deposition velocity also has been estimated for several land-use types. The typical deposition velocities are complex functions of surface types, atmospheric stabilities, friction velocities, air pollutants and so on. The canopy resistance is major contribution to the model's total resistance for O_3. Canopy wetness is also an important factor to calculate deposition velocity, We considered the canopy wetness as canopy water content(CWC) in our Model, But, it is not easy to observe CWC over each land-use types. In this study, we use CWC observed by EMEFS(CANADA Environment Service, 1988) to examine the influence of CWC in estimation of O_3 dry deposition velocity(V_4) in summertime. The value of O_3 V_4 range 0.2~0.7㎝ s^-4 on dry surface and 0.01~0.35㎝ s^-4 on wet surface in daytime.

Ozone is an important atmospheric pollutant that is occurred in tropospheric chemical process and it also affects the human health and plants. For a correct application of abatement strategies for ozone, it is necessary to understand the factors that control atmospheric ozone removal by dry deposition processes. The present study investigates the numerical simulation of the dry deposition velocity(V_(d)) obtained from PNU/DEM(Pusan National University Deposition Model). PNU/DEM includes seasonal categories, meteorological factors, surface properties and land-use types and proposes for and accurate numerical computation. And, this study examines the ability of the PNU/DEM to compute V_(d) of ozone over water surfaces and evaluates PNU/DEM by comparing its estimated V_(d) to past observed V_(d) over water. The parametrization was found to yield V_(d) values generally in good agreement with the observations for the deciduous forest and the coniferous forest. Ozone is removed slowly at wet surface of water due to its low water solubility. Therefore V_(d) values over water were lower than V_(d) values over the other surfaces. Comparison of PNU/DEM simulated V_(d) values to observations of ozone V_(d) that have been reported in the literature implies that PNU/DEM produces realistic results.

Most caterpillars, the larvae of butterflies and moths(Lepidoptera), are herbivorous. Sometimes they are regarded as serious agricultural pest that cause to damage agricultural produce, whereas some species such as Bombyx mori is known to be valued as sources of silk. Even though their major role in the ecosystem, details of biology are poorly known for most species. This study has been carried out to identify larvae and to acquire useful biological information of insect larvae through rearing from 1997 to 2014 in HECRI(Holoce Ecosystem Conservation Research Institution). From 2012 HECRI are carrying out ‘Larvae Identification and Specimen Security of Primary Endemic Moths in Korea Peninsula through Rearing’ supported by National Institute of Biological Resources(NIBR). Of these this study is the list about special caterpillars feeding on the foliage Willow Trees (Salix spp.) Total 143 species belonging to 13 families were collected and identified 69 species belonging to 12 families. Among them Willow Treesdependent monophagous caterpillars are 34 species belonging to 5 families, oligophagous 36 species belonging to 3 families and polyphagous 16 species belonging to 12 families. The dominant family is Geometridae(51 species), second is Noctuidae(35 species) and followed by Notodontidae(21 species).
