Objectives: The purpose of this study was to determine whether the sacrooccipital category II blocking technique may improve abdominal muscle endurance and alleviate shoulder pain caused by pelvic tilting. Methods: A total of 50 subjects diagnosed with category II sacroiliac joint instability and lower back pain were randomly assigned to the control or treatment group. The sacrooccipital technique category II blocking procedure (2-min duration) was performed 3 times a week until the category II indicator of joint instability had subsided. The control subjects were subjected to a sham procedure of equal duration and frequency. We assessed abdominal muscle endurance using the partial curl-up test and shoulder pain using a visual analogue scale, before and immediately after the intervention and 2 weeks after the intervention. Results: On two-way analysis of variance with repeated measures on time factor, significant treatment and interaction effects on muscle endurance were found. A significant interaction effect, but not treatment effect, was found for shoulder pain. Post hoc test showed that the shoulder pain was reduced immediately after intervention (treated group) and 2weeks (control and treated group) after the intervention as compared to before the intervention. Conclusions: This study suggests that sacrooccipital category II blocking can be used to alleviate shoulder pain caused by pelvic instability. The mechanisms behind the long-term benefits may include an increase in abdominal muscle endurance.

Extending the findings of Rajagopal and Burnkrant (2009), this research examines the moderating role of consumers' goals (i.e., head category-relevant goal vs. modifier category-relevant goal) in the effects of two different interpretation strategies (i.e., relational interpretation vs. property interpretation) on product beliefs and attitudes toward hybrid products. In the current research, we make two predictions. First, we predict that both head category and modifier category beliefs will be higher under property interpretations than under relational interpretations in the modifier category-relevant goal priming conditions, whereas there will be no significant differences between each product category beliefs across the two interpretation conditions in the head category-relevant goal priming conditions. Second, we predict that attitudes toward hybrid products will be higher under property interpretations than under relational interpretations in the modifier category-relevant goal priming conditions, whereas there will be no significant differences between the attitudes toward hybrid products across the two interpretation conditions in the head category-relevant goal priming conditions. These predictions are tested and confirmed in two experiments. Finally, we discuss theoretical and practical implications of our findings and develop directions for future research.

Semantic Role Decision defines the semantic relationship between the predicate and the arguments in natural language processing (NLP) tasks. The semantic role information and semantic category information should be used to make Semantic Role Decisions. The Sejong Electronic Dictionary contains frame information that is used to determine the semantic roles. In this paper, we propose a method to extend the Sejong electronic dictionary using word embedding and synonyms. The same experiment is performed using existing word-embedding and retrofitting vectors. The system performance of the semantic category assignment is 32.19%, and the system performance of the extended semantic category assignment is 51.14% for words that do not appear in the Sejong electronic dictionary of the word using the word embedding. The system performance of the semantic category assignment is 33.33%, and the system performance of the extended semantic category assignment is 53.88% for words that do not appear in the Sejong electronic dictionary of the vector using retrofitting. We also prove it is helpful to extend the semantic category word of the Sejong electronic dictionary by assigning the semantic categories to new words that do not have assigned semantic categories.

In this paper, we try to generalize ultraproducts in the category of locally convex spaces. To do so, we introduce D-ultracolimits. It is known [7] that the topology on a non-trivial ultraproduct in the category T $V^{ec}$ of topological vector spaces and continuous linear maps is trivial. To generalize the category Ba $n_{1}$ of Banach spaces and linear contractions, we introduce the category L $C_{1}$ of vector spaces endowed with families of semi-norms closed underfinite joints and linear contractions (see Definition 1.1) and its subcategory, L $C_{2}$ determined by Hausdorff objects of L $C_{1}$. It is shown that L $C_{1}$ contains the category LC of locally convex spaces and continuous linear maps as a coreflective subcategory and that L $C_{2}$ contains the category Nor $m_{1}$ of normed linear spaces and linear contractions as a coreflective subcategory. Thus L $C_{1}$ is a suitable category for the study of locally convex spaces. In L $C_{2}$, we introduce $l_{\infty}$(I. $E_{i}$ ) for a family ( $E_{i}$ )$_{i.mem.I}$ of objects in L $C_{2}$ and then for an ultrafilter u on I. we have a closed subspace $N_{u}$ . Using this, we construct ultraproducts in L $C_{2}$. Using the relationship between Nor $m_{1}$ and L $C_{2}$ and that between Nor $m_{1}$ and Ba $n_{1}$, we show thatour ultraproducts in Nor $m_{1}$ and Ba $n_{1}$ are exactly those in the literatures. For the terminology, we refer to [6] for the category theory and to [8] for ultraproducts in Ba $n_{1}$..

New types of fire accidents appear or the existing types disappeared because of rapidly changing society. We proposed a methodology of extracting new nouns from fire investigation data each of which is an accident report producted by fire investigators. The new nouns could be used in modifying the existing categories for classifying fire accidents. We analysed morphology of the product names and the ignition summaries using the proposed method for the fire accidents classified as the etc sub-category of the category of equipments involved in ignition. In this paper, we found "dryer" as a new sub-category of the agricultural equipment category and "boiler" in the seasonal appliance category from the product names of the fire accidents. We also extracted the new input keywords of "aquarium" and "monitor" in the commercial facilities category and the video, audio apparatus category from the ignition summaries respectively. Using the four subcategories, we reclassified 548 (14.39%) of 3,808 fire accidents assigned to the etc sub-category.

This study was undertaken in an attempt to; 1) measure value orientation of nursing activities, 2) identify the relationship between nurse's role perception and patient's expectation, and 3) evaluate the pattern of nursing education and nursing service administration. 203 hospitalized adults and 203 professional nurses from 11 general hospitals in Seoul during the period of July to December 1973 were tested according to questionnaire based on 4 categories of clinical nursing activities, 1) physical care, 2) observation and control, 3) psycho-social care and 4) therapeutic measures. Results of the study are as follows: 1. Nurses were more concerned than patients in the physical care category. Significant difference was revealed by p<.01 level (t=2.800). Mean value score of nurses was average (2.84), and mean value score of patients was relative' y low (2.49). None of the physical care category questionnaire items were over 3.5. 2. Respondents from hospitals of total care system revealed significant difference in the physical care category by P〈.025 level. (t=2.242). Mean value score of both group were average level (nurse 2.90, patient 2.53), nurses showed higher concern. 3. Difference between nurse's role perception and patient's expectation in observation and control category was revealed non- significance by p〉0.05. level (t=1.238). Mean value score of both group revealed relatively high (nurse=3.44, patient 3.19). 4. Difference between nurse's role perception and patient〉expectation in psycho-social cart category revealed non- significance by p〉.05 level (t=0.758), Mean value score of both group revealed average level (nurse =2.71, patient =2.53), 5. Non- significant difference was noted between B. S. N. and diploma nurse's role perception in the psycho- social care category by p> 0.1 level (t=0.316). 4. Difference between nurse's role perception and patient's expectation in the rapeutic me assures category revealed non- significance by p〉0.05 level) t=0.503). Horses showed high concern by mean value score 3.56 level and patients relatively high by 3.41. All items of this category revealed very high or relatively high value score.
