The aim of this research was to verify the mediating effects of ambivalence over emotional expressiveness and distress tolerance on the relationship between harm avoidance and depression. A total of 403 university students completed TCI-RS(Temperament and Character Inventory-Revised Short version), AEQ-K(Ambivalence over Emotional Expressiveness Questionnaire-Korean), DTS (Distress Tolerance Scale) and CES-D(The Center for Epidemiologic Studies Depression Scale). The results revealed that harm avoidance and ambivalence over emotional expressiveness were positively related with depression, and negatively related with distress tolerance. In addition, the relationship of harm avoidance and depression was successively mediated by ambivalence over emotional expressiveness and distress tolerance. That is, the motivation of emotional expression conflict may have an effect on depression and the distress tolerance would play an important role in therapeutic intervention of depression.

This study proposes a novel reverse N-Gram approach to overcome the limitations of traditional N-Gram methods and enhance performance in building an entity dictionary specialized for the healthcare sector. The proposed reverse N-Gram technique allows for more precise analysis and processing of the complex linguistic features of healthcare-related big data. To verify the efficiency of the proposed method, big data on healthcare and digital health announced during the Consumer Electronics Show (CES) held each January was collected. Using the Python programming language, 2,185 news titles and summaries mentioned from January 1 to 31 in 2010 and from January 1 to 31 in 2024 were preprocessed with the new reverse N-Gram method. This resulted in the stable construction of a dictionary for natural language processing in the healthcare field.

In spite of much progress in vitro fertilization and embryo transfer (IVF-ET) program, the pregnancy rate remains at 20-30%, and the endometrial implantation rate per embryo transferred at 10-15%. As a result, about 90% of embryos may fail to implant to the endometrium, and many attempts such as optimization of follicular development, improvement of in vitro culture system including coculture, and micromanipulation of zona pellucida have been made to improve embryonic implantation after IVF-ET. Recently, several procedures of assisted hatching (AH) using micromanipulation have been introduced, and pregnancies and births have been obtained after AH. To develop and establish AH as an effective procedure to improve embryonic implantation, AH with partial zona dissection (PZD) was performed in 116 cycles of 89 infertile couples who had previous repeated failures of standard IVF-ET more than two times (Group I: 71 cycles in 54 patients), or who had implantation failure of embryos with good quality (Group II: 15 cycles in 13), or who had undergone AH without specific indication (Group III: 30 cycles in 22) from January, 1995 to Februry, 1996, and the outcomes of AH were analyzed according to pregnancy rate. The number of oocytes retrieved after controlled ovarian hyperstimulation (COH) was $9.9{\pm}7.1$ in Group I, $11.5{\pm}4.5$ in Group II, and $7.9{\pm}6.4$ in Group III. The number of embryos transferred after AH was $4.7{\pm}1.8$ in Group I, $5.3{\pm}1.3$ in Group II, and $3.5{\pm}2.4$ in Group III. The mean cumulative embryo score (CES) was $56.8{\pm}30.0$ in Group I, $76.1{\pm}35.9$ in Group II, and $38.5{\pm}29.9$ in Group III. The overall clinical pregnancy rate per cycle and per patient was 12.7% (9/71) and 16.7% (9/54) in Group I, 33.3% (5/15) and 38.5% (5/13) in Group II, and 6.7% (2/30) and 9.1% (2/22) in Group III, respectively. There were significant differences in the numbers of oocytes retrieved and embryos transferred, CES, and the clinical pregnancy rate per cycle among three groups. There was a significant inverse correlation between basal serum FSH level and CES, and no pregnancy occurred in patients with CES less than 20. In conclusion, AH of human embryos with PZD prior to ET has improved the implantation and pregnancy rates in IVF-ET patients with the past history of repeated failures, especially in spite of transfer of embryos with good quality, and AH will provide a range of novel techniques which may contribute much to effective management of infertile couples.

Objectives : The objective of the present study was to investigate alexithymia in major depressive disorder(MDD) and subclinical depression(SCD). Methods : Three hundred eighty-six community-dwelling adults(238 females and 148 males, age 19-79; mean age $43.0{\pm}13.9$) were recruited. Structured clinical Interview for DSM-IV(SCID) was conducted for the diagnosis of MDD or other Axis I psychiatric disorders. The Center for Epidemiological Studies for Depression Scale(CES-D) and the Totonto Alexithymia Scale(TAS) were administered to assess depressive symptom and alexithymia, respectively. Among subjects without MDD, those who had minor depressive disorder on the SCID or high scores(i.e. over 16) on the CES-D were defined as subjects with SCD. TAS total score and factor I, II, III scores of TAS in MDD, SCD, and non-depressive controls were compared. Results : Among 386 subjects, 38 subjects(9.8%) were diagnosed as MDD by DSM-IV criteria, while 57 subjects(14.8%) were classified into SCD group. There were significant differences between 3 groups(MDD, SCD and non-depressive controls) in total score($F_{2,383}=14.0$, p<0.01), factor I(difficulty in identifying feeling)($F_{2,383}=23.4$, p<0.01) and factor II(difficulty in describing feeling)($F_{2,383}=7.8$, p<0.01), but not factor III(external oriented thinking)($F_{2,383}=1.8$, p=0.16) of TAS. In post-hoc analysis, both MDD subjects and SCD subjects had higher scores in TAS total, factor I and factor II, compared to non-depressive controls(all p<0.01). In contrast, there were no significant differences between MDD subjects and SCD subjects in any TAS factor. Conclusion : In this study, both MDD subjects and SCD subjects were more alexithymic than non-depressive control subjects. These findings suggest that SCD, as well as MDD, is also related to alexithymia.

The existed transmissions have PDH and SDH transmission system, which are based on PSTN network. But as the future ATM network is going to be constructed, it is very necessary for ATM network to interwork with PSTN for telephony service. The international standardization organizations like ITU-T, ATM Forum offered CES, VTOA1, VTOA2 and so on for interworking with PSTN service, which spend many network resources and considerable transmission delay. So in this paper, new interworking PSTN for transmission will be proposed to lessen the transmission delay and the network resources.

Many research and development activities have found that Superconducting Generators (SCG) have advantages such as high efficiency, light weight, small size, large unit size and good steady-state stability over conventional ones. However the transient stability of SCG is comparable to that of conventional ones. One way to improve the transient stability of SCG is to apply quick-response excitation system to the SCG. For this purpose, an SCG with an electrothermal shield of short electric time constants should be developed. In this paper, a new electrothermal shield, called slitted electrothermal shield(SES), is proposed. The SES can easily transmit radiated heat into the ends of the shield as in the conventional electrothermal shields(CES) and can easily pass magnetic flux produced by armature and field windings. By finite element analysis and experimental test, the slitting effects of SES on magnetic shielding are compared. Good agreement is obtained between simulated and test results.

Purpose: The study was designed to examine the relationship of perceived entrapment to anger and depression in adolescent women. Method: Seven hundred sixty-five adolescent women were recruited from two high schools located in Seoul, Korea for a descriptive study. The instruments used were The Entrapment Scale for perceived entrapment, Spielberger's state trait anger expression inventory-Korean version for state anger and trait anger, and The Center for Epidemiology Studies Depression Scale(CES-D) for depression. Results: The score of perceived entrapment significantly correlated with state anger, trait anger and depression. The significant predictors of depression in adolescent women were perceived entrapment, state anger and trait anger explaining 47.6% of the variance in depression. Conclusion: This study showed that perceived entrapment is an important predictor for depression. Therefore, in order to reduce depression in adolescent women, it is necessary to design an intervention program that helps with coping and reduces perceived entrapment.
