Ten promising polyvoltine mulberry silkworm strains(SDMGl, SDMG2, SDMG3, SDMG4, SDMWl, SDMW2, RMWl, RMW2, RMW3 and RMW4) that are superior in quantitative and qualitative traits have been synthesized in the polyvoltine breeding laboratory of Andhra Pradesh State Sericulture Research ＆ Development Institute, Hindupur through systematic hybridization and appropriate selection methods. After the genotypes were found homozygous for the desired traits, they have been crossed with 3 bivoltine testers $(APS8, APS4 and {NB_2}{D_4})$ and thirty new hybrid combinations were developed for the assessment of their hybrid performance. Phenotypic expressions of economically important quantitative and qualitative traits of fist filial generation were measured and subjected for statistical analysis. Evaluation Index and Subordinate Function methods were employed for the assessment of hybrid performance since they are widely used in silkworm hybrid evaluation. Total of seven poly${\times}$bivoltine combinations, which ranked high in both the methods, were selected as potential combinations for further field test. These combinations also ranked significantly higher than the control hybrid (APMl${\times}$APS8).

This study aimed to assess the roll of various abusive factors on suicide thoughts. In particular, the effects of negligence, physical and emotional abuse, as the subordinate variables of abuse, were examined on suicide ideation. In addition, the mediation effects of shame-proneness and friendships were also investigated. To achieve these specific objectives, subordinate dimensions of abuse such as negligence, physical abuse and emotional abuse were measured for 277 male and 275 female students from Seoul middle schools using a measurement tool. Specifically, experiences of being abused and neglected, the level of suicide thoughts using scale for suicidal ideation (SSI), the level of shame-proneness and friendships using personal feelings questionnaire-2(PFQ-2), and schoolmate relationships were measured using a questionnaire. Analysis of collected data revealed that while suicide thoughts showed significant positive relationship with abuse and shame-proneness, there was a significant negative relationship between suicide thoughts and friendships. In particular, negligence, physical abuse and emotional abuse had significant effects on suicide ideation, while emotional abuse had the greatest effect on suicide ideation. Shame-proneness and friendships partially mediated abuse and suicide thoughts. The findings of this study have contributed to understanding of factors related to suicide thoughts. In particular, the mediation effects of shame-proneness and friendships have been highlighted.

There are customer services jointly provided by two facilities so that each customer will complete the course made up of both facilities' sub-services. The two facilities are assumed invested respectively by an infrastructure owner and one subordinate facility owner, whose partnership is built on their capital investments. This paper presents a mathematical model of Stackelberg competition between the two facility owners to derive their optimal Nash equilibrium. In this study, each facility owner's profit is consisted of fixed revenue fractions of sold services, operating costs (including depreciation cost) and maintenance costs of her facility. The maintenance costs of one facility are incurred both by failures and deterioration due to usage. Moreover, for both facilities, failures are rectified immediately by minimal repairs and preventive maintenance is carried out at a fixed time epoch. Additional assumptions are also employed to develop the model such as customer arrivals are manipulated to follow a Poisson process, and each facility's lifetime is independently Weibull-distributed. The Stackelberg game proceeds as follows. At the first stage of decision making process, the infrastructure owner (acting as a leader) decides the allocation of revenue shares based on her self-interest. After observing the allocation of revenue shares, the subordinate facility owner determines her own optimal price of services. This paper investigates actions and reactions of the two partners in the system. Then analytical conditions are proposed to achieve a unique optimal Nash equilibrium. Finally, some suggestions for further research are discussed.

With increasing number of dental patients, it is also increasing patient's desire to get better medical service. As the concern for improvement of dental medical service quality is growing, satisfaction degree of dental patients is becoming very important. This study was to investigate difference of patients' satisfaction degree concerned with installation of dental labs and the reason. The data for this study were collected through Self-Administered Questionnaires from 284 patients who had visited dental clinics more than two times. The results are as follows: Female respondents ratio was as twice much as male ones. And 54.2% of the respondents were found out to have completed university education. Dental clinics with dental labs scored higher than others in patients' satisfaction and recommendation willingness degree. Dental clinics without dental labs scored higher in patients' revisiting willingness degree. With simple Correlation Analyses it was found out that the most influential variable concerned with patients' general satisfaction degree was medical facility in dental clinics with dental labs, dentist ability to cure in dental clinics without dental labs. There were some discrepancies with other subordinate variables. Through Stepwise Multiful Regression Analyses it was found out that the most influential variable with patients' general satisfaction degree was dentist ability to cure in total and dental clinics without dental labs and medical facility in dental clinics with dental labs. There were also some discrepancies with other subordinate variables.
