A hierarchical representation scheme for planar curves, MBO-tree, is proposed in this paper, which provides natural approximation and efficient localization. MBO-tree is based on the Douglas-Peucker algorithm (iterative end-point fit algorithm), but approximation errors that are stored with corresponding points in MBO-tree nodes and are used for abstraction measures are adjusted by force to eliminate unnatural approximation. The error adjusting is just making the approximation error of a node in a MBO-tree to be less than or equal to that of its parent. In point of localization, the bounding area of a curve is represented with a minimum bounding octangle (MBO), which can enclose the curve more compactly compared with those of other hierarchical schemes, such as the strip tree, the arc tree and the HAL tree. The MBO satisfies the hierarchical inclusion property that is useful for hierarchical geometrical operations, such as the point-inclusion test and the polygon intersection test. Through several experiments, we found that the proposed scheme was able to approximate more naturally and to localize more effectively.

Purpose: It is a descriptive study to analyze correlation between the perception of management by objectives(MBO) and organizational effectiveness among clinical nurses. Methods: The subjects were 315 nurses at two hospitals (A and B) of C university, who have had more than 3.5 years of nursing experience. The survey instrument included two major concepts, perception of MBO (29 items) and organizational effectiveness, which has three sub-concepts, job satisfaction (18 items), organizational commitment (12 items), and motivation (20 items). The data analyses included t-test, ANOVA, Scheffe test, Pearson's correlation coefficients, and Stepwise multiple regression. Result: The mean score of the perception of MBO was 3.13 out of 5. In organizational effectiveness, job satisfaction was 3.09, organizational commitment 3.25, and motivation 3.38. The perception of MBO had significantly positive correlation with job satisfaction(r=.71), organizational commitment(r=.65) and motivation (r=.61). The perception of MBO explained 50.4%, 42.4%, and 37.1% for job satisfaction, organizational commitment, and motivation respectively. Conclusions: The results show that the MBO affected the organizational effectiveness, and the MBO serves as a useful system to improve the organizational effectiveness in a nursing department.

Objective: Microencapsulation is a technique to improve stability, bioavailability, and controlled release of active ingredients at a target site. This experiment aimed to investigate the effects of microencapsulated basil oil (MBO) on growth performance, apparent ileal digestibility (AID), jejunal histomorphology, bacterial population as well as antioxidant capacity of broiler chickens in a tropical climate. Methods: A total of 288 one-day-old female broilers (Ross 308) were randomly allocated into 4 groups (6 replicates of 12 birds), based on a completely randomized design. Dietary treatments were as follows: i) basal diet (NC), ii) basal diet with avilamycin at 10 ppm (PC), iii) basal diet with free basil oil (FBO) at 500 ppm, and iv) basal diet with MBO at 500 ppm, respectively. Results: Dietary supplementation of MBO improved average daily gain, and feed conversion ratio of broilers throughout the 42-d trial period (p<0.05), whereas MBO did not affect average daily feed intake compared with NC group. The broilers fed MBO diet exhibited a greater AID of crude protein and gross energy compared with those in other groups (p<0.05). Lactobacillus spp. and Escherichia coli populations were not affected by feeding dietary treatments. Both FBO and MBO had positive effects on jejunal villus height (VH), villus height to crypt depth ratio (VH:CD) and villus surface area of broilers compared to NC and PC groups (p<0.05). Superoxide dismutase level in the duodenal mucosa of MBO group was significantly increased (p<0.01), whereas malondialdehyde level was significantly decreased (p<0.01). Conclusion: Microencapsulation could be considered as a promising driver of the basil oil efficiency, consequently MBO at 500 ppm could be potentially used as a feed additive for improvement of intestinal integrity and nutrient utilization, leading to better performance of broiler chickens.

Malignant bowel obstruction (MBO), an occasional complication in patients with advanced urological cancer, causes gastrointestinal symptoms such as nausea and vomiting leading to suffering which severely impairs quality of life (QOL). Drug therapy, especially octreotide, a synthetic analog of somatostatin, is reportedly effective in controlling the symptoms of MBO. In the present study, we administered octreotide to urological cancer patients with MBO and evaluated the improvement of subjective symptoms, oral intake, and nasogastric intubation. Fourteen terminally ill urological cancer patients suffering with MBO were included (age range 55-92, 10 male, 4 female). Octreotide was administered at $300{\mu}g/day$ to those patients subcutaneously as a continuous injection. Significant improvements in subjective symptoms were observed in thirteen patients (92.8%), and ten patients (71.4%) were able to resume oral intake. Four patients required nasogastric drainage before the administration of octreotide, but nasogastric intubation was discontinued in all these cases after the use of octreotide. Early initiation of octreotide resulted in better improvement of MBO symptoms, and no adverse event was observed in any of the patients. These results revealed that $300{\mu}g/day$ dose of octreotide is safe and effective for managing gastrointestinal symptoms of terminally ill urological cancer patients with MBO. We also recommend starting the treatment with ocreotide as soon as MBO is diagnosed.

Utilizing fit theory in strategic human resource management, this study examines the impact of two HR practices on newcomer turnover rates. While there is a growing body of research identifying the linkage between high-performance work systems(HPWS) and improved organizational performance through higer employee commitment, little research addresses how specific mechanisms among the systems deliver different performances to organizations. Using management by objective(MBO) and job rotation in HPWS, we found a strong main effect of each practice-it decreases newcomer turnover rates. This main effect becomes stronger when one practice combined with another, showing synergy exists. Linking HPWS research to turnover, this study provides insightful evidence of interactions between MBO and job rotation for organizational performance.

This methodological research was designed to develop performance evaluation key indicators (PEKIs) for management by objectives (MBO) and to estimate their weights for hospital nurses. Methods: The PEKIs were developed by selecting preliminary indicators from a literature review, examining content validity and identifying their level of importance. Data were collected from November 14, 2007 to February 18, 2008. Data set for importance of indicators was obtained from 464 nurses and weights of PEKIs domain was from 453 nurses, who worked for at least 2 yr in one of three hospitals. Data were analyzed using $X^2$-test, factor analysis, and the Analytical Hierarchy Process. Results: Based upon Content Validity Index of .8 or above, 61 indicators were selected from the 100 preliminary indicators. Finally, 40 PEKIs were developed from the 61 indicators, and categorized into 10 domains. The highest weight of the 10 domains was customer satisfaction, which was followed by patient education, direct nursing care, profit increase, safety management, improvement of nursing quality, completeness of nursing records, enhancing competence of nurses, indirect nursing care, and cost reduction, in that order. Conclusion: PEKIs and their weights can be utilized for impartial evaluation and MBO for hospital nurses. Further research to verify PEKIs would lead to successful implementation of MBO.

The contribution of a type II restriction-modification system (R-M system) to genome integrity and cell viability was investigated. We established experimental conditions that enabled the achievement of hemimethylated and unmethylated states for the specific bases of the recognition sequences of the host's DNA. To achieve this, we constructed the MboII R-M system containing only one (i.e., M2.MboII) out of two functional MboII methyltransferases found in Moraxella bovis. Using the incomplete R-M system, we were able to perturb the balance between methylation and restriction in an inducible manner. We demonstrate that upon the SOS-induced DNA repair in mitomycin C treated cells, restriction significantly reduces cell viability. Similar results for the well-studied wild-type EcoRI R-M system, expressed constitutively in Escherichia coli, were obtained. Our data provide further insights into the benefits and disadvantages of maintaining of a type II R-M system, highlighting its impact on host cell fitness.
