Application of a new photocatalyst has been attempted to improve the efficiency and rates of photocatalytic degradation of azo dyes by using a model dye such as Methyl Orange. As a new photocatalyst, $TiO_2$ encapsulated EFAL-removed zeolite Y ($TiO_2$ /EFAL-removed zeolite Y) has been synthesized by ion-exchange in the mixture of EFAL-removed zeolite Y with 0.05 M aqueous [$(NH_4)_2 TiO(C_2O_4)_2.H_2O$] [$TiO(C_2O_4)_2.H_2O$]. This new photocatalyst has been characterized by measuring XRD, IR and reflectance absorption spectra as well as ICP analysis, and it was found that the framework structure of $TiO_2$ /EFAL-removed zeolite Y is not changed by removing the extra-framework aluminum (EFAL) from the normal zeolite Y and the $TiO_2$ inside the photocatalyst exists in the form of $(TiO^{2+})_n$ nanoclusters. Based on the ICP analysis, the Si/Al ratio of the $TiO_2$ /EFAL-removed zeolite Y and the weight of $TiO_2$ were determined to be 23 and 0.061g in 1.0g photocatalyst, respectively. It was also found that adsorption of the azo dye in the $TiO_2$ /EFAL-removed zeolite is very effective (about 80 % of the substrate used). This efficient adsorption contributes to the synergistic photocatalytic activities of the $TiO_2$ /EFAL-removed zeolite by minimizing the required flux diffusion of the substrate. Thus, the photocatalytic reduction of methyl orange (MO) was found to be 8 times more effective in the presence of $TiO_2$ /EFAL-removed zeolite Y than in the presence of $TiO_2$ /normal zeolite Y. Furthermore, the photocatalytic reduction of MO by using 1.0 g of the $TiO_2$ /EFAL-removed zeolite Y containing 0.061g of $TiO_2$ is much faster than that carried out by using 1.0 g of Degussa P-25.

Mother and infant relationship has a great influence on child's developments. Expecially, mother and infant relationship is affected by mother and infant interactions during one year after birth and an omen of mother-infant interaction after birth is mother-fetus interaction. This study was conducted to develop mother-fetus interaction promotion program of talking and tactual stimulation aimed at enhancing sensitivity of primiparas and to evaluate the effect of the nursing intervention program on mother-fetus interaction and mother-infant play interaction. Non-eguivalent control group posttest design was used, and Blumer's symbolic interaction theory and Barnard's mother-infant interaction model was used a conceptual framework of this study. Fifty primiparas and infant(26 mother-infant dyads for intervention group and 24 dyads for control group) were recruited from three general hospital and an OBGY clinic located in Kwang Nung city. Data was collected from January 30th to December 20th in 2001. For the intervention group, programed education which focused on mother-fetus interaction in the 1st trimester. Telephone counselling was provided with interval of two weeks. For two groups, home visiting for data collection of mother- fetus interaction was conducted at 36 to 38 weeks of gestational age. And mother-infant play interactions were assessed at 4 to 6 weeks after birth using videotapes. Play situations were videotaped and two trained observers analyzed the tapes. The data were analyzed using chi-square test and Fisher's Exact Test to test the equivalence of two groups, and the effect of intervention progrom was determined with t-test and Wilcoxon Rank Sum test. The results were as follows: 1. The significant difference was found in mother-fetus interaction between two groups(t=2.085, P=0.0425). It indicated that intervention progrom was effective in improving mother-fetus interaction. 2. The significant difference was found in mother-infant play interaction between two groups(W=347.5, P=0.0001). In subscale analysis, three subscales showed significant differences between the groups: interactional behavior of mother(t=5.921, P=0.0001), interactional behavior of infant(t=5.736, P= 0.0000), and synchronic interactional behavior of mother and infant(t=7.940, P= 0.0000). In conclusion, this study has shown that the applied nursing intervention aimed at enhancing sensitivity of primiparas promoted mother-fetus interaction and mother-infant play interaction. Therefore, this study suggests that this nursing interventions to increase maternal sensitivity to the fetus's movement should be broadly applied to primiparas, which can be beneficial for formation of mother - infant relationship, and for promotion the social, affective, and cognitive developments of their children.

Layered double hydroxides(LDHs)가 토양의 이화학성에 미치는 영향 및 결정성의 변화를 규명하기 위하여 LDHs가 처리된 토양침출수를 calcium carbonate 처리와 비교 조사하였다. LDHs와 $CaCO_3$를 처리한 토양의 pH는 유사한 pH 변화를 나타내었으나, LDHs를 처리한 토양의 pH가 무처리구 및 $CaCO_3$ 처리구에 비해 각각 3.0 및 1.0 높게 낮타났다. LDHs를 첨가한 토양침출수의 $Mg^{2+}$ 함량은 52.0~383.0 mg/l으로 무처리구의 1.0~10.0 mg/l, $CaCO_3$ 처리구의 1.0~20.0 mg/l 보다 매우 높았다. $Al^{3+}$ 함량은 LDH와 $CaCO_3$ 처리구에서 0.2 mg 이하의 수준으로 무처리구에 비해 낮은 함량을 나타내었다. 토양침출수의 인산 함량은 LDHs와 $CaCO_3$ 처리에 의해 유의성 있는 상관관계는 나타나지 않았으며, silicate 함량은 LDHs와 $CaCO_3$ 처리에 의해 낮아졌다. LDHs는 토양에서 층상형의 기본구조가 점진적으로 붕괴되어 결정성 및 구조적 형태가 변화되었다. 따라서 LDHs의 토양처리는 산성 토양의 개선 및 식물영양원의 지속적 공급이 가능할 뿐만 아니라 토양환경 및 이화학성에 큰 영향을 미치지 않으므로 다양한 농업소재의 기능성 전달체로서 활용성이 매우 높은 것으로 판단된다.

The purpose of the present study is to identify the mediation effect of hope between fatigue and psychosocial adjustment in women with breast cancer. The framework for this study was guided by concepts and propositions derived from the theoretical and empirical literature on fatigue, hope and adjustment. The design of this study is a descriptive correlation study using a cross-sectional design. One hundred and twenty two outpatients with early breast cancer, receiving post-surgical radiation therapy or chemotherapy, were selected from three major medical centers in Seoul, Korea. A packet including PABCF (Psychosoical Adjustment to Breast Cancer Factor), revised RPFS (Revised Piper Fatigue Scale), HHI (Herth Hope Index), and self-addressed return envelope was given to the participants at seven to eight weeks post surgery. The questionnaires were to be completed at home and returned to the researcher by mail. The obtained data were analyzed using three regression equations guided by Baron and Kenny (1986); first, hope was regressed on fatigue; second, psychosocial adjustment was regressed on fatigue; and third, psychosocial adjustment was regressed on fatigue and hope, simultaneously. In the first equation, fatigue explained 4% of the variance in hope. In the second equation, fatigue explained 47% of the variance in psychosocial adjustment. In the last equation, hope and fatigue significantly explained the variance in psychosocial adjustment. Therefore, all conditions for the test of mediation effect of hope were satisfied. For the test of the mediation effect, the beta coefficients of fatigue on psychosocial adjustment on the second and third regression equations were compared. The beta coefficients were decreased from .69 (p < .001) on the second regression equation to .63 (p < .001) on the third regression equation. Thus, the hypothesis of this study was supported. As a result of this study, the negative Influence of fatigue on psychosocial adjustment is dampened through the mediator effect of hope in women with breast cancer. Therefore, when planning care for the adverse effect of fatigue on psychosocial adjustment, oncology nurses should consider hope as a mediator between fatigue and psychosocial adjustment to breast cancer.

A study was made to investigate a relationship existing in the dentoskeletal framework and the soft tissue profile around the face, and compare the sexual differences between boys and girls having the normal occlusion in the mixed dentition. The lateral cephalograms were composed of 67 boys aged 10.3 years and 68 girls aged 10.4 years, respectively. By means of the lateral cephalograms, both the hard-and soft tissue structures were simultaneously analyzed, measured and evaluated by introducing the several reference items: S-N plane, palatal plane, mandibular plane, N-A line and A-P line for the dentoskeletal structures and N’-P’line for the soft tissue, and the 21 measuring points for the both structures. The significant findings were as follows: 1. In general the boys showed the larger nasal component dimension than did the girls, but the length and height of nose(N’-Prn and NA-Prn) showed the significant sexual difference among those when evaluated statistically. 2. The lip-thickness was found to be minimal in the region of nasion, greater in the region of pogonion, and much greater in the region of point A in the both sexes, but the only thickness over point A(A-A’) showed the significant sexual difference statistically. 3. The upper and lower lip position were found to be located anteriorly to the esthetic line in the both sexes, but upper lip position showed the significant sexual difference when evaluated statistically. 4. The regions of nose and upper lip had a tendency not to be following the underlying skeletal profile.

Knowledge of how metal releases from the stainless steels used in food processing applications and cooking utensils is essential within the framework of human health risk assessment. A new European standard test protocol for testing metal release in food contact materials made from metals and alloys has recently been published by the Council of Europe. The major difference from earlier test protocols is the use of citric acid as the worst-case food simulant. The objectives of this study were to assess the effect of citric acid at acidic, neutral, and alkaline solution pH on the extent of metal release for stainless steel grades AISI 304 and 316, commonly used as food contact materials. Both grades released lower amounts of metals than the specific release limits when they were tested according to test guidelines. The released amounts of metals were assessed by means of graphite furnace atomic absorption spectroscopy, and changes in the outermost surface composition were determined using X-ray photoelectron spectroscopy. The results demonstrate that both the pH and the complexation capacity of the solutions affected the extent of metal release from stainless steel and are discussed from a mechanistic perspective. The outermost surface oxide was significantly enriched in chromium upon exposure to citric acid, indicating rapid passivation by the acid. This study elucidates the effect of several possible mechanisms, including complex ion- and ligand-induced metal release, that govern the process of metal release from stainless steel under passive conditions in solutions that contain citric acid.
