  • The purpose of this study was to investigate the pulpal responses to adhesive resins as phosphoric ester system: "Clearfil F II" (Composite filling material), "Panavia EX" (Composite cementing Material) and "Silar" (Microfilled Compsoite resin) comparing with Zinc-Oxide-Eugenol cement. Total 70 cavities of the permanent healthy teeth from 5 dogs were prepared and placed with experimental resins and Zinc-Oxide-Eugenol cement as control. The dogs were sarificed at 5 intervals of 3 days, one, two, four, six weeks. The specimens were routinely prepared and stained by Hematoxylin-Eosin. Followings were the results obtained through microscopic examination. 1. In cases of Clearfil F II and Panavia EX without etching and lining, pulp response in the early stage showed more severe vascular congestion and hemorrhage than that of Zinc-Oxide-Engenol cement. 2. The pulp response of totally etched cases was similar to that of unetched cases in the groups of Clearfil F II and Panavia EX. 3. The cases of Clearfil F II and Panavia EX with enamel etching showed no significant histologic change compared to that of total cavity etching. 4. The Silar case with total etching showed retarded tendency of histologic recovery compared to Clearfil F II and Panavia EX group. 5. Generally, pulp responses of experimental groups were not severe and the six week case showed the evidence of a histologic recovery.

  • Objective : The purpose of this study was to develop the somatization rating scale (SRS), and then to use the scale in clinical pracitice. Methods: First, a preliminary survey was conducted for 109 healthy adults to obtain 40 response items. Second, a preliminary questionnaire was completed by 215 healthy subjects. Third, a comparison was made regarding somatization responses among 242 patients (71 with anxiety disorder. 73 with depressive disorder, 47 with somatoform disorder, and 51 with psychosomatic disorder) and 215 healthy subjects. Results : Factor analysis yielded 5 subscales : cardiorespiratory and nervous responses, somatic sensitivity, gastrointestinal responses, general somatic responses, genitourinary, eye and muscular responses. Reliability was computed by administering the SRS to 62 healthy subjects during a 2-week interval. Test-retest reliability for 5 subscales and the total score was significantly high, ranging between .86-.94. Internal consistency was computed, and Cronbach's ${\alpha}$ for 5 subscales ranged between .72-.92, and .95 for the total score. Convergent validity was computed by correlating the 5 subscales and the total score with the total score of the global assessment of recent stress (GARS) scale, the perceived stress questionnaire (PSQ), and the symptom checklist-90-revised (SCL-90-R). The correlations were all at significant levels. Discriminant validity was computed by comparing the total score and the 5 subscale scores of the patient and control groups. Significant differences were found for 5 subscales and the total score. Only the depressive disorder group was siginificantly higher than control group in all the subscale scores and total scores of SRS among 4 patient groups. In somatic sensitivity, only depressive disorder patients were significantly higher than the normal controls, whereas in general somatic subscale, depressive disorder and somatoform disorder groups were significantly higher than the normal controls. In total scores of the SRS, female subjects were significantly higher than males. Conclusion : These results indicate that the SRS is highly reliable and valid, and that it can be utilized as an effective measure for research in stress- and somatization-related fields. The depressive disorder and somatoform disorder groups showed more widespread somatization than the anxiety and psychosomatic disorder groups.

  • The purposes of this study were to determine the actual state of the indoor air quality by TVOC concentration and residents' responses and to analyze the influencing factors of IAQ in newly built university dormitory. The field measurements on the levels of TVOC and HCHO were carried out three times at an interval of 4 weeks in 3 rooms of a dormitory. The questionnaire survey on the residents that inquired into the lifestyle, the consciousness related to IAQ, and the responses of SHS was fulfilled. According to the results, the level of TVOC was approximately $0.14{\sim}18.5ppm$ and HCHO was $0.23{\sim}6.89ppm$ during 3 month since construction completion, which are seriously in excess of standard level, and seemed to be on the decrease as time goes by. The factors influencing the differences of the levels of TVOC or HCHO were the amount of ventilation including infiltration, heating temperature, relative humidity, or the use of living things including chemical. However, the residents rarely felt the responses of SHS and did not be conscious of the importance of ventilation.

  • The purpose of the present study is to investigate the effect of time remaining to use mileage in the notification message from retailers on consumer responses. A total of 577 consumers participated in experiments involving different notification messages of the time remaining to use mileage. Results showed: 1) a significant difference in mileage benefit perception, positive emotion, negative emotion, attitude toward retailers, and repurchase intention according to the remaining time to use mileages, 2) benefit perception positively affected positive emotion and negatively affected negative emotion; positive emotion positively affected and negative emotion negatively affected attitude toward retailers; and attitude positively affected repurchase intention on retailers, and 3) the remaining time to use mileages moderates the relationship between attitude and repurchase intention. Findings highlighted the importance of timing of the message to notify the consumer as to remaining time to use mileage. In the case of a message indicating long remaining time to use mileage, consumers showed more positive responses toward retailers than did consumers who had a message indicating short remaining time to use mileage. These results can be used as guidelines to select the optimal time to send notification messages of remaining time to use mileage in order to generate positive consumer responses.

  • This study explores the effect of information direction and order of cosmetics power bloggers on consumer responses. A total of 488 undergraduate students participated in experiments with mock-up stimuli of sunscreen product reviews by power bloggers. The study was conducted with four stimuli of product review posts (i.e., positive reviews only, positive-negative reviews in order, negative-positive reviews in order, negative reviews only) of the power bloggers. The results showed a significant difference in consumer responses according to information direction and order of product reviews of the power bloggers. Specifically, negative reviews were considered more objective and more useful than positive reviews were. However, positivity of reviews is crucial in generating more positive attitudes toward products, greater purchase intention, and greater word-of-mouth intention. In regard to information order, the negative-positive reviews generated more positive attitudes toward the product and greater purchase intention than did the positive-negative reviews, emphasizing the importance of ending product reviews with positive information so as to create positive responses. Referring to the findings, power bloggers and marketers using bloggers as a promotional tool would benefit by carefully designing information content in consideration of an appropriate direction and order of information to better fit their purpose.

  • Great efforts have been conducted to investigate the seismic performances of the arch and rectangular underground structures, however, the differences between seismic responses of these two types of underground structures, especially the vault radian influencing the seismic responses of arch structures are not clarified. This paper presents a detailed numerical investigation on the seismic responses of arch underground structures with different vault radians, and aims to illustrate the rule that vault radian affects the seismic responses of underground structures. Five arch underground structures are built for nonlinear soil-structure interaction analysis. The internal forces of the structural components of the underground structures only under gravity are discussed detailedly, and an optimum vault radian for perfect load-carrying functionality of arch underground structures is suggested. Then the structures are analyzed under seven scaled ground motions, amounting to a total of 35 dynamic calculations. The numerical results show that the vault radian can have beneficial effects on the seismic response of the arch structure, compared to the rectangular underground structures, causing the central columns to suffer smaller axial force and horizontal deformation. The conclusions provide some directive suggestions for the seismic design of the arch underground structures.

  • This paper presents an experimental investigation of asymmetric impact effects on hydroelastic responses. A 1:64 scaled segmented ship model with U-shape open cross-section backbone was newly designed to meet elastic similarity conditions of vertical, horizontal and torsional stiffness simultaneously. Different wave heading angles and wavelengths were adopted in regular wave test. In head wave condition, parametric rolling phenomena happened along with asymmetric slamming forces, the relationship between them was disclosed at first time. The impact forces on starboard and port sides showed alternating asymmetric periodic changes. In oblique wave condition, nonlinear springing and whipping responses were found. Since slamming phenomena occurred, high-frequency bending moments became an important part in total bending moments and whipping responses were found in small wavelength. The wavelength and head angle are varied to elucidate the relationship of springing/whipping loads and asymmetric impact. The distributions of peaks of horizontal and torsional loads show highly asymmetric property.

  • Plants are challenged by various pathogens throughout their lives, such as bacteria, viruses, fungi, and insects; consequently, they have evolved several defense mechanisms. In addition, plants have developed localized and systematic immune responses due to biotic and abiotic stress exposure. Animals are known to activate DNA damage responses (DDRs) and DNA damage sensor immune signals in response to stress, and the process is well studied in animal systems. However, the links between stress perception and immune response through DDRs remain largely unknown in plants. To determine whether DDRs induce plant resistance to pathogens, Arabidopsis plants were treated with bleomycin, a DNA damage-inducing agent, and the replication levels of viral pathogens and growth of bacterial pathogens were determined. We observed that DDR-mediated resistance was specifically activated against viral pathogens, including turnip crinkle virus (TCV). DDR increased the expression level of pathogenesis-related (PR) genes and the total salicylic acid (SA) content and promoted mitogen-activated protein kinase signaling cascades, including the WRKY signaling pathway in Arabidopsis. Transcriptome analysis further revealed that defense-and SA-related genes were upregulated by DDR. The atm-2atr-2 double mutants were susceptible to TCV, indicating that the main DDR signaling pathway sensors play an important role in plant immune responses. In conclusion, DDRs activated basal immune responses to viral pathogens.

  • This study examines the effects of collaboration type and brand sensitivity on consumer responses toward fashion collaboration brands. For this study, six brands of fashion collaboration were selected by collaboration types: collaboration with same industry (Uniqlo-Jill Sander, H&M-Sonia Rykiel, and Levis-Jean Paul Gaultier) and collaboration with different industries (LG-Prada, Samsung-Armani, and LG-Levis). A selfadministered questionnaire was developed based on the literature that mainly included brand sensitivity, consumer response (brand association, brand values, and purchase intention), and marketing strategic elements in the context of fashion collaboration. For collecting the data, respondents were asked to choose and assess a previously purchased brand. A total of 299 usable data responses were obtained from Korean consumers aged from 15 to 40 years old. The consumer response toward the fashion collaboration brand consisted of four factors: Emotional value, perceived quality, symbolic value, and brand association. The results showed that the collaboration type had the main effect on emotional value, symbolic value, and purchase intention. Brand sensitivity had the main effect on brand association, emotional value, symbolic value, and purchase intention. There was also an interaction effect on emotional value. With respect to strategic marketing elements, product differentiation, premium pricing, and value pricing had partially positive effect on consumer responses; however, promotion had a negative effect on consumer responses (e.g., perceived quality, and emotional value). In addition, collaboration type or brand sensitivity moderated the effect of strategic marketing elements on consumer responses. This study discussed a managerial implication to develop a strategic brand alliance to manage brand equity in the fashion marketplace.
