Intertidal community recovery and resilience were investigated with quantitative and qualitative perspectives as a function of disturbance timing. The study was conducted in a lower intertidal rock bed of the southern coast of South Korea. Six replicates of artificial disturbance of a $50cm{\times}50cm$ area were made by clearing all visible organisms on the rocky substrate in four seasons. Each of the seasonally cleared plots was monitored until the percent cover data reached the control plot level. There was a significant difference among disturbance timing during the recovery process in terms of speed and community components. After disturbances occurred, Ulva pertusa selectively preoccupied empty spaces quickly (in 2-4 months) and strongly (50-90%) in all plots except for the summer plots where non-Ulva species dominated throughout the recovery period. U. pertusa acted as a very important biological variable that determined the quantitative and qualitative recovery capability of a community. The qualitative recovery of communities was rapid in summer plots where U. pertusa did not recruit and the community recovery rate was the lowest in winter plots where U. pertusa was highly recruited with a long duration of distribution. In this study, U. pertusa was a pioneer species while being a dominant species and acted as a clearly negative element in the process of qualitative recovery after disturbance. However, the negative effect of U. pertusa did not occur in summer plots, indicating that disturbance timing should be considered as a parameter in understanding intertidal community resilience in temperate regions with four distinct seasons.
Purpose: The present study was conducted to develop the Life Respect Enhancement Program and test its effectiveness on suicide knowledge, suicide intervention skills, self-efficacy in suicide prevention, and gatekeeper behaviors among nursing officers. Methods: The program was developed according to the ADDIE model and finalized after practical need analysis, expert verification, and a preliminary study. The present study used a concurrent embedded mixed-method research design. To compare the effects of the Program and the control group on the outcome variables, a quantitative study was conducted using a nonequivalent control group with a pretest-posttest design. Quantitative data were analyzed using χ2-tests, t-tests, and RM-ANOVA. A qualitative study was conducted using FGI with six members of the experimental group 3 months after intervention completion. Results: In total, 56 nursing officers participated in the 3-month follow-up test. Compared to the control group, the experimental group showed significant improvements in suicide knowledge, suicide intervention skills, and self-efficacy in suicide prevention scores at post-test. The significant group differences in suicide knowledge and suicide intervention skills were maintained at 3 months. The gatekeeper behavior scores of the experimental group were also significantly higher than those of the control group at 3 months. Qualitative analysis of the participants' experiences with the Program yielded two themes and seven sub-themes. Conclusion: The newly developed Life Respect Enhancement Program demonstrates significant effects on suicide knowledge, suicide intervention skills, and gatekeeper behaviors. Thus, this program is recommended to promote suicide prevention competencies among nursing officers in military clinical settings.
This empirical test of the efficacy of the literature-based reading instruction was conducted with 63(31 male and 32 female) 2nd grade elementary school children. Subjects in the experimental group had 40-45 minutes literature-based reading instruction twice weekly; those in the control group had only basic text reading. Procedures included a pilot study, pre-test, experimental period, and post-test. Research instruments included the Basic Learning Skill Test(Park et al., 1988), the Qualitative Reading Inventory(Leslie & Caldwell, 1990), and the Elementary Reading Attitude Survey(Mckenna & Kear, 1990). Data were graded and scored by each research question and then analyzed with a t-test of differences between the groups. The experimental group showed higher word recognition, text comprehension, and story grammar strategies than the control group. They also showed more improvement in each of these categories than the control group.

Purpose: The purpose of this study was to conduct a pre-conception care program for women of childbearing age with inflammatory bowel disease (IBD) in Korea and verify its effects on self-efficacy for IBD management, IBD-related pregnancy knowledge, and IBD-related pregnancy anxiety. It also aimed to explore the changes in participants through the program. Methods: A convergent mixed-methods study design was adopted. In the quantitative phase, 35 women (17 and 18 in the intervention and control group, respectively) participated. The intervention group attended a program that included small-group sessions and individual tele-coaching. To confirm the effects, data were collected before and one and four weeks after the intervention. In the qualitative stage, focus group interviews and tele-coaching were conducted with the intervention group. Results: After the program ended, significant differences were observed over time between the intervention and control groups for self-efficacy for IBD management (Wald χ2 = 4.41, p = .036), IBD-related pregnancy knowledge (Wald χ2 = 13.80, p < .001) and IBD-related pregnancy anxiety (Wald χ2 = 8.61, p = .003). Qualitative data analysis revealed the following themes: (1) improving confidence in IBD management and awareness for planned pregnancy; (2) improving IBD awareness related to pregnancy and childbirth; and (3) relieving anxiety about and actively facing pregnancy. Conclusion: This study is meaningful in that, to the best of our knowledge, it is the first to develop a pre-conception care program for women diagnosed with IBD and confirm its effectiveness. Furthermore, this program is expected to be suitable for patient counseling and education in clinical practice.

This study analyzed some of the discrepancies in quantitative and qualitative data focusing on cognitive and affective achievement in science education. Academic and affective achievement score of 308 high school students were collected as quantitative data, and 33 students were interviewed for qualitative data. We examined the causes and types of discrepancies in terms of testing tools. As a result from quantitative data, there were a large number of students with a big difference between subjects in cognitive achievement, and constructs in affective achievement. More than 20% of the students did not match tendency between achievements in two areas. Through interviews, some examples such as intentional control of science learning for future study and careers, different responses by differences in perception between school science and science, appeared. A comparison of quantitative data by testing tool between qualitative ones and interviews showed conflicting result, where most students evaluated themselves differently from their own quantitative data. That is due to the students' interaction with the testing tools. Two types of discrepancy related to testing tool are found. One is 'the concept difference between the item developer and students,' the other is 'the difference between students' exposed response and their real mindset.' These are related to the ambiguity of the terms used in the tool and response bias due to various causes. Based on this study, an effort is required to elaborate the testing item that matches students' actual perception and to apply students' science learning experience to testing items.

Introduction: Andhra Pradesh (AP) is one of the largest tobacco producing states in India. About 29% of adults in AP currently use tobacco in some form. Almost 24% of males and 4% of females are smokers. The prevalence of tobacco use in the state is higher than the national average of 15% for male and 2% for female smokers. However, few attempts have been made to understand the current situation of tobacco control resources, activities and strategies in the context of such a high tobacco prevalence state. The present study aimed to identify the gaps in existing tobacco control program and areas where tobacco control efforts can be integrated. Methods: Data were collected using both quantitative and qualitative methods. Semi-structured interviews were undertaken with a total of 95 key officials of state health departments, program managers, and project directors in six districts to understand ongoing tobacco control efforts. To facilitate the interviews, semi-structured guides were developed. Simple descriptive statistical analysis was conducted on the quantitative data using SPSS version 17. Results: The results of the situational analysis suggest that a sufficient health workforce and infrastructure with the potential to integrate tobacco control activities is available in the surveyed districts. However, lack of integration of the tobacco control program intothe tuberculosis control program and the National Rural Health Mission was observed. Information, education and communication activities were lacking at block level health facilities. Conclusions: Our findings indicate that lack of trained health professionals, paucity of dedicated funds, lack of information, education and communication materials and low priority given to tobacco control activities are some of the factors which impede integration of tobacco control into existing health and developmental programmes in the districts of Andhra Pradesh, India.

The purpose of this study was to examine the effects of peer scaffolding on the writing fluency of English language learners. This study was intended to confirm that peer scaffolding in English as a foreign language (EFL) writing classes can improve students' English proficiency. An analysis of 20 EFL learners studying at a university in Gyeonggi Province was conducted based on the English Proficiency Test. In this study, 20 intermediate learners with similar proficiency levels were included in the sample. Randomly, 10 students were designated as members of the control group, and 10 students were designated as members of the experimental group. In the experimental group, students practiced essay writing, while a skilled student provided scaffolding for a less skilled student. A variety of tools were used to gather data, including tests, questionnaires, and interviews Statistical analyses of quantitative data were conducted using t-tests for independent samples, whereas analyses of qualitative data were conducted based on themes. Pre-test results indicated a significant value of sig. =0.87, which was higher than α = 0.05. According to the results of this study, the writing performance of both experimental and control groups of students was equal and homogeneous prior to treatment. However, there were significant differences between the writing of students in the two groups after the completion of the program. Due to the post-test analysis of the writing test, the test resulted in a sig. =0 .043, a value lower than α = 0.05. As a result, the experimental group participants showed a marked improvement in their writing abilities after treatment.

The purpose of this study is to construct a substantive theory that described and explained how pregnant women are seeking information in context of pregnancy. A qualitative design based on the method of grounded theory was utilized. In-depth interviews were conducted with 16 pregnant women, selected by theoretical sampling who receiving antenatal care 3 different university hospitals. The interview data were transcribed and systematically analyzed according to the open coding, axial coding and selective coding. 'Increasing Sense of Self-Control over Pregnancy' was the core category for describing and guiding the process of seeking information during the pregnancy. To construct a theory of 'Increasing Sense of Self-Control over Pregnancy' in this study, eight hypothetical statement were generated from the relationships among the core category and the other categories, thus four patterns were derived as follows: 'Desperately Seeking', 'Actively Seeking', 'Unconcernedly Seeking', 'Resignedly Seeking'. The implications of the findings are discussed in terms of development of LIS theory in Korea, theory development of information behavior, education for LIS, and information service practice. The suggestions for further research are provided.
The purpose of this study was to verify the effects of psychodrama group counselling, and to determine its applicability as a nursing intervention for the promotion of mental health of clients in their developmental stages. Methodological triangulation was used for research design. For quantitative study, quasi experimental study design with nonequivalent control group was used to test the effects of psychodrama group counselling. For each experimental and control group convenient samples of 15 nursing students were selected, and observed from May to Nov. 2000. For experimental group, the treatment was given for 2 hours each week, totaling 20 hours. The questionnaire consisted of 24 items of physical symptoms from CMI. 40 items of Spielberger Anxiety Scale, and 21 items of Beck Depression Scale. Reflective journal was written by the experimental group. The data were analyzed using chi-square and Mann-Whitney U test. For the qualitative study, the contents of the reflective journal were analyzed into categories and classifications. The results of the study were as follows; 1. There was a significant difference on physical health status between the experimental and the control group 2. There was a significant difference between two groups on the mean scores of mental health before and after psychodrama group counselling. 3. The qualitative analysis of reflective journal resulted in 4 categories and 13 classifications, which was reflected by the experience of the psychodrama group counselling. The four categories were self introspection, psychological support, improvement of interpersonal relationship and self development. The thirteen classifications are self-discovery, discovering others, emotional catharsis, positive thinking, formation of consensus, comforting, being free, being comfortable, understanding, maturing personal relationship, acquiring self-confidence, new challenges, and planning for the future. Based on the study findings, the psychodrama group counselling had promoted not only physical but also mental health of nursing students. The characteristics identified by the study suggested the applicability of psychodrama group counselling as an effective measure of nursing intervention for clients.

This study investigated how air traffic controllers (ATCs) perceive the visual information on radar screen and examined quantitative and qualitative differences as a function of expertise. Little research has shown that how much information is processed by ATC visually and perceptually, how ATCs represent the information, and what difference exists between experts and novices. Participants were asked to draw representing visual information on the blank sector map after a 5-second exposure. Data were analyzed by a superimposing method to identify correctly represented information. Results showed that the expert group had much larger size of chunking and their pattern was wider and more accurate than the novice group. The practical application and methodological implications are also discussed for further research.
