Utilizing information and knowledge is one of the major objectives in the management of construction firm. This trend has been developed both inside of the firms and overall industry-wise. Therefore conventional methods of performance evaluation based on the financial statements such as balance sheet under GAAP(Generally Accepted Accounting Principles) are not sufficient to cover various Performance of constriction firms. Core competency of construction firms needs to be evaluated by the new performance evaluation model. In this research, the concept of BSC (Balanced Score Cards) is utilized to develop the performance evaluation model for construction firms considering four major performance indicators including financial perspective, customer perspective, learn and growth perspective, anti internal business perspective. A model of performance evaluation including criteria is proposed to evaluate construction firms based on their vision and strategy.

Purpose: This study was to analyze the quality of life of married women practicing a natural family planning method based on given parameters in order to obtain some specific basic data for developing holistic programs to enhance the quality of life of married women practicing natural family planning. Methods: The subjects of this study were selected from married women who had been practicing natural family planning over two years. Data were collected from May 20 2001 to March 5 2002 using a structured questionnaire and interviews. The total number of subjects was 239. Collected data were analyzed using PC-SAS, which utilized descriptive statistics. In addition, LISREL 8.0 program was used to utilize covariance matrix. Results: The hypothetical model was reasonably fitted to commonly accepted data. Revision was required for the x2 value and RMR, and the model was revised by eliminating 6 paths. The revised model was fit well for commonly accepted data (x2 = 86.26, GFI = 0.97, NFl = 0.98, NNFI = 0.99, AGFI = 0.96, RMR = 0.02, CN= 422). Variables that influence the practice of natural family planning were communication of spouses, knowledge about natural family planning, self-efficacy and perceived benefits. Variables that control the quality of life were self-efficacy, internal health locus of control, attitude toward natural family planning, communication of spouses, perceived benefits and natural family planning behaviors. Conclusions: These findings prove that the quality of life of married women practicing natural family planning can be improved through developing programs that enhances communication of spouses, self-efficacy and perceived benefits.

BACKGROUND/OBJECTIVES: North Korean refugees (NKRs) in South Korea are a unique population as they must adapt in a new country with similar cultural traits but different social, political, and economic systems, but little research has been conducted on diet and nutrition in this population. This study examined food security, dietary behaviors, and nutrient intakes among adult NKRs living in South Korea and compared them to those of South Koreans. SUBJECTS/METHODS: The subjects were 139 adult NKRs (25 men, 114 women) living in the Seoul metropolitan area, and 417 age- and sex- matched South Korean controls (SKCs; 75 men, 342 women) selected from the Korea National Health and Nutrition Examination Survey (KNHANES). Food security and dietary behaviors (meal skipping, eating-out, meals with family, nutrition education and counseling, and nutrition label knowledge and utilization) were obtained using self-administered questionnaires. Nutrient intakes were assessed by 24-hr recall. The statistical analysis was performed using IBM SPSS ver. 23.0. RESULTS: In South Korea, food security had improved over the previous 12 months, but remained significantly poorer for NKR women than SKC women. Meal skipping was three times more frequent than for SKCs and eating-out was rare. Average energy intake was 1,509 kcal for NKR men and 1,344 kcal for NKR women, which was lower than those of SKCs (2,412 kcal and 1,789 kcal, respectively). Significantly more NKRs (men 24.0%, women 21.9%) showed simultaneously deficient intake in energy, calcium, iron, vitamin A, and riboflavin than SKCs (men 2.7% (P = 0.003), women 7.0% (P < 0.001)). NKR women had a significantly higher index of nutrient quality (INQ) for some nutrients than SK women. CONCLUSIONS: This study reports significant differences in food security, dietary behaviors, and nutrient intakes between NKRs and SKCs. Generally, NKRs reported lower intakes despite improved food security, but relatively good INQs across nutrients. Further research is needed to understand processes of food choice and consumption among NKRs to provide appropriate support aimed at improving diets.

Background: The use of herbal preparations as remedies for various medical conditions has continuously increased in Korea Large proportions of Korean patients use herbal medicinal products, folk remedies, and food supplements. However, studies on the safety of herbal products arc conducted on a less than sufficient basis even in the countries like Korea where herbal medicine is being used extensively. Some of the reports on the safety of herbs were done by the doctors of western medicine but lack of knowledge and misclassification led to misunderstandings. Objecitves: This study aims to review the recent evidences on hepatotoxic events associated with the use of herbal medicinal products, folk remedy, and food supplements. In the process, this review will grasp trends in this field of studies and will direct further researches into the right direction. Methods: Systematic literature searches were performed on MedRic and MEDLIS in Korea. Screening and selection of the articles and the extraction of data were performed independently by two of authors. There were no restrictions regarding the published date. In order to avoid bias, the articles written by medical doctors, not by oriental doctors were selected. 43 journals were chosen for the review. Results: Analyzing the number of journals, studies on the drug-induced liver injury were increased after the year 2000. The proportion of herbal and folk remedy associated hepatotoxic injuries in all drug-induced liver injury was $21.0\%-30.0\%$. But criterion for herbal medicine is rather vague and limited objective data hindered objectiveness. Few of single medicinal herbs and combination preparations were associated with hepatotoxic injuries. But because of lack of objectivity, further researches must be conducted to yield more concrete results. Conclusions: yield more concrete results. Incidence figures are largely unknown, and in most cases a causal attribution is not established. The challenge for the future is to systematically research this area, educate all parties involved, and minimize patient risks.

As a result of a growing demand for various mobile devices, the demand for application programs on the devices is on the rise. The Java language that is platform-independent rapidly rose as the best programming language for mobile devices. However, the Java has a problem that does not support platform-dependent features needed by the application. To solve this problem, the JNI technology was introduced by Sun Microsystems. Programmers using the JNI to write native methods need to have a lot of knowledge about the JNI and the internal structure of the JVM. Also, the increased load by using a number of JNI functions may decrease software productivity and quality. Demands for tools writing native method without understanding of JNI are progressively increasing. To develop these tools, it is necessary to translate automatically the differences between Java and C/C++. In this study, I suggested a way to overcome differences between both languages and developed JNI editor that is an integrated develope environment on the basis of this.

Several recent advances in our knowledge of thyroid physiology have broad application to the diagnosis and management of thyroid disorders. For in the thyroid, more than other endocrine organs, pathophysiology can be translated directly into the diagnosis and management of thyroid disease. Graves' disease is a syndrome including goiter with hyperthyroidism, exophthalmos and dermopathy. The pathogenesis of Graves' disease is not yet clearly identified, but various autoantibodies to the thyroid gland and immunopathologic studies indicate that autoimmune processes are involved in the pathogenesis of the disease. The diagnosis and management of Graves' disease are largely dependent on radionuclide techniques as radioimmunoassay, radioactive iodine therapy and so on. Several laboratory tests are also developed to determine the remission of this disase including TRH stimulation test, $T_3$ suppression test and detection of thyroid stimulating immunoglobulins. Autoimmune thyroiditis is almost certainly a primary immunologic disease and the incidence tends to increase recently, mainly due to the application of biopsy technique in thyroid diseases. Thyroid nodules have been a great challenge to physicians because of the possibility of malignancy. But recently, cytologic examination of thyroid aspirate provides a very simple and also reliable diagnostic method in patients with thyroid nodules. In 163 patients with thyroid nodules, only 19.3% was revealed to be malignant. Therefore cytologic examination of thyroid aspirate and thyroid biopsy should be included in the diagnosis of nodular patients prior to surgical intervention. In this paper, a comprehensive review is presented on the pathogenesis, clinical features, laboratory findings and therapeutic modalities of various thyroid diseases on the basis of over 80 researches performed during the past 20 years at radioisotope clinic, Seoul National University Hospital.

Since Anton van Leeuwen­hoek first observed a surface-associated multicellular structure of bacterial cells in the 17th century, it has been shown to exhibit an ability to form a biofilm by numerous bacterial species. The biofilm formation is composed of distinct developmental stages, which include an attachment/adhesion of a single cell, a proliferation toward monolayered coverage, a propagation to aggregated microcolony, a maturation to 3-dimensional structure, and subsequently a local degradation. Investigation to identify the essential factors for bacterial biofilm formation has been performed via classical genetic approaches as well as recently developed technologies. The initial stage requires bacterial motility provided by a flagellum, and outermembrane components for surface signal interaction. Type IV-pilus and autoaggregation factors, e.g., type I-fimbriae or Ag43, are necessary to reach the stages of monolayer and micro colony. The mature biofilm is equipped with extracellular polymeric matrix and internal water-filled channels. This complex architecture can be achieved by differential expressions of several hundred genes, among which the most studied are the genes encoding exopolysaccharide biosyntheses and quorum-sensing regulatory components. The status of our knowledge for the biofilms found in humans and natural ecosystems is discussed in this minireview.

Nondestructive testing methods are required to assess the condition of civil structures and formulate their maintenance programs. Axial force identification is required for several structural members of truss bridges, pipe racks, and space roof trusses. An accurate evaluation of in situ axial forces supports the safety assessment of the entire truss. A considerable redistribution of internal forces may indicate structural damage. In this paper, a novel compressive force identification method for prismatic members implemented using static deflections is applied to steel beams. The procedure uses the Euler-Bernoulli beam model and estimates the compressive load by using the measured displacement along the beam's length. Knowledge of flexural rigidity of the member under investigation is required. In this study, the deflected shape of a compressed steel beam is subjected to an additional vertical load that was short-term measured in several laboratory tests by using fiber Bragg grating-differential settlement measurement (FBG-DSM) sensors at specific cross sections along the beam's length. The accuracy of midspan deflections offered by the FBG-DSM sensors provided excellent force estimations. Compressive load detection accuracy can be improved if substantial second-order effects are induced in the tests. In conclusion, the proposed method can be successfully applied to steel beams with low slenderness under real conditions.

There exists a many-to-many mapping relationship between persons and their names. A person may have multiple names, and different persons may share the same name. These synonymous and homonymous names may severely deteriorate the recall and precision of the person search, respectively. This study addresses the characteristics of features for resolving homonymous author names appearing in citation data. As disambiguation features, previous works have employed citation-internal features such as co-authorship, titles of articles, titles of publications as well as citation-external features such as emails, affiliations, Web evidences. To the best of our knowledge, however, there has been no literature to deal with the influences of features on author disambiguation. This study analyzes the effect of individual features on author resolution using a large-scale test set for Korean.
