This study summarizes domestic and foreign previous works on fluvial terrace with absolute ages to discuss formative process of climatic terrace in Korea. Different from traditional climatic terrace model, approximately three quarters from foreign works have argued that formation of climatic terrace can be attributed to medium- and short-term climatic change or other environmental factors, rather than long-term climatic change of glacial and interglacial cycles. Based on previous works on fluvial terrace in Korea, it can be suggested that fluvial terrace in Korea formed not due to long-term climatic change of 100,000-year cycles related to glacial and interglacial cycles, but due to medium- and short-term climatic change or climatic event of tens of thousands of years related to intensity change in summer monsoon, one of the important factors affecting precipitation in Korea.

It has been suggested that morphologic characteristics of the periodontium are partly related to the shape and form of the teeth. Furthermore, the severity of symptoms of periodontal disease have been proposed to differ among these various morphologic entities or "biotypes". The purpose of the present study was to examine the relationship between the form of the crowns in the maxillary anterior tooth segment and (1) a group of morphological characteristics and (2) the thickness of the gingiva. The thickness of gingiva was measured by ultrasonic device(SDM). 100 subjects devoid of symptoms of destructive periodontal disease were examined regarding, e.g., probing depth, gingival recession, width of keratinized gingiva, thickness of the keratinized gingiva. From maxillary study cast, the width(at the apical third-CW) and the length(CL) of the crowns of the 6 anterior teeth were determined. A CW/CL-ratio was calculated for each tooth and averaged for each tooth region. The individual mean CW/CL-ratio values for the central incisors were ranked. The 10 subjects ranked highest and the 10 ranked lowest were selected as having either a long-narrow(group N) or a short-wide(group W) form of the crown of the tooth. The data for each of the examined parameters were averaged for each tooth region in each subject and mean values for subjects in groups W and N were compared using the Student t-test. Stepwise multiple regression analysis, including data from the whole sample, was performed for each tooth region with the thickness of the free gingiva as the dependent variable. The results from the analyses demonstrated that individuals with a long-narrow form of the central incisors displayed, compared to individuals with a short-wide crown, form (l) a narrow zone of keratinized gingiva, (2) a pronounced "scalloped" contour of the gingival margin. There was no significant difference between groups N and W with respect to the thickness of the keratinized gingiva. The CW/CL-ratio data revealed that a certain form of the crowns in the central incisors was accompanied by a similar form in the lateral incisors and canine tooth region. The regression analyses demonstrated that the thickness of the keratinized gingiva in central, lateral incisors and canines was significantly related to the width of the keratinized gingiva.

Objectives : The purpose of this study is to find out the effects of muscle energy techniques on nuchal pain caused by traffic accidents. Methods : The 20 patients were divided into 2 groups: group A was treated except muscle energy techniques and group B was treated with muscle energy techniques. Both groups were treated with acupunture treatment, physical theraphy and herbal medication. Patients were evaluated by McGill Pain Questionnaire-Short Form(SF-MPQ), Pain Disability Index(PDI) and Neck Disability Index(NDI) in traffic accident patients. Results : 1. Both Group were significantly decreased in sensory of SF-MPQ, VAS, PDI and NDI after 7 days of treatment. 2. Group B compared with the Group A was significantly decresed in VAS, PDI after 7 days of treatment. Conclusions : We found out that muscle energy techniques is considered to be effective and useful on nuchal pain caused by traffic accidents.

Researchers have been long studying new building implementation methods to improve the quality of construction, reduce the time of assembly, and increase productivity. One of these methods is the use of modular pre-fabricated structural forms that are composed of a beam, column, short column, pyramidal end block, and connection plates. In this study, a new geometry for the pyramidal end block was proposed that helps facilitate the assembly procedure. Since the proposed configuration affects the performance of this form of connection, its behavior was evaluated using finite element method. For this purpose, the connection was modeled in ABAQUS and then validated by comparing the outputs with experimental results. The research proceeded through analyzing 16 specimens under monotonic and cyclic loading. The results indicated that using the pyramidal end block not only makes the assembly process easier but also reduces the out-of-plane displacement of the short column webs and the vertical displacement of beam end. By choosing appropriate section properties for column and beam, the connection can bear a rotation up to 0.01 radians within its inelastic region and a total of 0.04 radians without any significant reduction in its bearing capacity.

Negative expressions have their semantic function of classical negation as a pure reverser of truth-values. They also have various kin and foes of their pragmatic functions such as association of bad feelings (Russell 1948), emphasis/attenuation by negative polarity items, sarcasm, and metalinguistic negation (MN). This paper explores how MN and descriptive negation (DN) differ and whether the difference creates pragmatic ambiguity (Horn 1987) or reflects merely contextual variations of one logical negation (Carston 1996). To test the debate, this paper treats certain degree modifiers licensed exclusively by MN as in Mia-ka POTHONG/Yekan yeppu-n key an-i-a [external neg] (vs. modifier NPIs like cenhye 'at all', licensed only by DN) and contrasts them with bad utterances of the MN modifiers in [short form neg] sentences (not for MN) such as Mia-ka POTHONG an yeppu-e. The ERP results of the well-formed vs. ill-formed conditions evoked the N400 at Cz in written stimuli and the N400 near the center on both hemispheres in spoken stimuli. The results suggest that the anomalies are meaning-related and tend to support the pragmatic ambiguity.

The aim of this study was to review studies on factors related to empowerment of patient with chronic diseases in Korea. By a literature search of databases, a total of 14 quantitative studies published in both Korean and English between January 2011 and April 2020 were identified. All the studies used a cross-sectional design and the majority of the studies used regression analyses. In 4 (28.6%) studies adopted Diabetes Empowerment Scale-Short Form (DES-SF) as the instrument to measure empowerment. The results confirm that self-care, social support, health literacy, and quality of life are associated with empowerment of patients with chronic diseases in Korea. This study will provide basic data with developing instruments and intervention programs of empowerment of patients with chronic diseases in Korea.

Purpose: This study examined the effects of individual reminiscence therapy on older adults' depression, morale, and the quality of life. Methods: The design was a single-group pre-test and post-test study. Subjects consisted of 31 older adults from two senior centers and a welfare center in Seoul. Individual reminiscence therapy was applied to study subjects four times, once a week for an hour at each time. Measurement tools were the Geriatric Depression Scale Short Form Korea (GDSSF-K) for depression, Mun Ae-ri's (1996) scale for morale, and Medical Outcomes Study Short Form 36 (SF-36) for the quality of life. Data was analyzed using descriptive statistics, paired t-test, and pearson correlation. Results: The application of individual reminiscence therapy reduced older adults' depression (t=-5.65, p=.000), and enhanced older adults' morale (t=4.65, p=.000). The application of individual reminiscence therapy improved older adults' quality of life (t=5.00, p=.000). Conclusion: Findings of the study suggest that individual reminiscence therapy may be applied as a nursing intervention that contributesto the improvement of older adults' quality of life, reduces their depression, and enhances their morale.

Objectives: Experiencing early childhood trauma is related to multiple psychiatric problems in adolescents and adulthood. This study aimed to examine the reliability and validity of the Korean version of the Early Trauma Inventory Self Report-Short Form (ETISR-SF) among Korean adolescents. Methods: A total of 86 adolescents aged 12-17 years (mean age $14.50{\pm}1.35years$, range 12-17) were assessed using the ETISR-SF. Other instruments, including the Children's Depression Inventory (CDI), the revised Children's Manifest Anxiety Scale (RCMAS), and the List of Threatening Experiences Questionnaire (LTE-Q), were used to assess clinical symptoms. After 2 months, 51 of the 86 participants were evaluated using the ETISR-SF to assess test-retest reliability. Results: The Cronbach's coefficient alpha for the ETISR-SF was high (0.803). Adolescents with depressive disorder showed higher ETISR-SF scores compared to healthy controls. The ETISR-SF scores were correlated higher with the scores on the LTE-Q (r=0.485) than with the scores on the CDI or RCMAS (r=0.165 and 0.347, respectively). Conclusion: The ETISR-SF was temporally stable, showing acceptable reliability (r=0.776). These findings suggest that the Korean version of the ETISR-SF appears to be a reliable and valid instrument for the measurement of reported childhood trauma.

Purpose: The International Classification of Functioning, Disability and Health (ICF) model was proposed by the World Health Organization for enhancing interdisciplinary communication. The purpose of this study was to examine the functional status of acute stroke patients using ICF core sets-short form. Methods: A set of 15 ICF items on functional status was used by nurses for their daily nursing assessment on functional status in 44 acute stroke patients in a university hospital. Results: The highest level of function was "consciousness", while the lowest was "defecation". Compared with functional status on the first day, consciousness, ingestion, language (mental), and defecation functions were significantly improved on the 14th day. However, there was no significant changes in items on activity and participation or environmental functions. Conclusion: These findings suggest that the function-specific nursing interventions for acute stroke patients need to be developed. Future research needs to test the usefulness of ICF items as an measurement tool.
