The aim of this study was to assess effects of aromatherapy on anxiety and depression of caregivers for patients in rehabilitation therapy and to provide basic data for the aromatherapy. Beck Anxiety Inventory(BAI) and Beck Depression Inventory(BDI) for the preliminary assessment of anxiety and depressive mood were administered to caregivers for patients in rehabilitation therapy in Chungbuk National University Hospital. Forty two out of seventy subjects who got scores above 10 in BDI were selected. Forty two Participants were divided into orange group, lavender group and control group. They had got the aromatherapy by using the lamp diffusion method for 4 weeks. Only forty participants completed a trial. Effects of the aromatherapy were measured using BAI, Hamilton Anxiety Rating Scale(HAM-A), BDI, Hamilton Depression Rating Scale(HAM-D), Self Esteem Scale(SES) and Index of Wellbeing(IOWB) before and after the aromatherapy. Orange group showed significant difference in the change of BDI scores compared with control group. Lavender group showed significant difference in the mean change of BAI, BDI and IOWB scores compared with control group. These results suggested that aromatherapy with orange oil was effective for depression and the aromatherapy with lavender oil was effective for anxiety as well as depression.

Sequential estimation of parameters in a compound Poisson process whose jump sizes are one-parameter exponential class random variables is discussed. Cramer-Rao type information inequality is used as an efficiency cirterion. Unbiased estimators for certain parametric functions whose variance attain the lower bound are all characterized with the corresponding sampling plans.

In this paper, finite p-groups G satisfying $N_G(H){\leq}H^G$ for every non-normal subgroup H of G are completely classified. This solves a problem proposed by Y. Berkovich.

In this paper, we propose an analysis model for the performance of channel error probability in Stream Control Transmission Protocol (SCTP) using Markov model. In this model it is assumed that the compressor and decompressor work in Unidirectional Mode. And the average throughput of SCTP protocol is obtained by finding the throughputs of when the initial channel state is good or bad.

Objectives : The aim of this study was to determine whether intervention using a multidisciplinary approach affects maternal mental health, parenting stress, and sense of parenting competence in children with feeding disorder and failure to thrive (FTT). Methods : Children with feeding disorder and FTT were randomized to the intervention group (N=11) or control group (N=8). We administered the Korean standardization of Parent Temperament Questionnaire for Children (K-PTQ) in both groups before intervention, and the Korean version of the Parenting Stress Index-Short Form (K-PSI-SF), Korean version of the Parenting Sense of Competence (K-PSOC), Korean version of the Beck's Depression Inventory (K-BDI), Korean version of the Beck Anxiety Inventory (K-BAI), and Korean version of the Mood Disorder Questionnaire (K-MDQ) in both groups before and after the intervention. Results : In the intervention group, the K-BDI (p=.068), K-BAI (p=.068), and K-MDQ (p=.066) scores tended to show a decline, the K-PSI-SF scores for stress related to child learning showed a significant decline, and the K-PSOC scores for sense of parenting competence showed significant improvement. However, no significant changes were observed in the control group. Conclusion : Use of a multidisciplinary approach improved maternal mental health, parenting stress, and sense of competence. Comparison of these results with those of normal control will be necessary in a future study.

Two forms of glucoamylase (GI and GII) from starch-grown Lipomyces kononenkoae CBS 5608 mutant were purified to apparent homogeneity by means of ultrafiltration, Sephacryl S-200 gel filtration and DEAE Sephadex A-50 chromatography. The apparent molecular weight was calculated as ca. 150 kDa for GI and ca. 128 kDa for GII, respectively. Both enzymes were glycoproteins with isoelectric points of 5.6 (GI) and 5.4 (GII). They had a pH optimun of 4.5 and were stable from pH 5 to 8. The temperature optimum for both enzymes was $60^{\circ}C$, but they were rapidly inactivated above $70^{\circ}C$. The $K_m$ values toward starch were estimated to be 6.57 mg per ml for GI and 4.52 mg per ml for GII, and the $V_{max}$ values were 16.28 ${\mu}M$ per mg for GI and 32.25 ${\mu}M$ per mg for GII, respectively. The $K_m$ and $V_{max}$ values of GII for ${\alpha}-$ or ${\beta}-cyclodextrin$ were estimated to be 0.15 mg per ml and 2.0 mg per ml, respectively ($K_m$) and 1.02 ${\mu}M$ per mg or 1.02 ${\mu}M$ per mg, respectively ($V_{max}$). Neither enzyme exhibited pullulanase activity but they released only glucose from starch or cyclodextrin. Amino acid analysis indicated that both glucoamylases were enriched in proline and acid amino acids. Glucoamylase GII strongly cross-reacted with a monoclonal antibody raised against GI enzymes, and the two enzymes shared very similar amino acid composition. Western blot analysis indicated that L. kononenkoae CBS 5608 mutant produced two forms of glucoamylase on starch, and that synthesis of them was subject to glucose repression.
