The morphometry and distribution of the unarmoured dinoflagellates Brachidinium capitatum F.J.R. Taylor, Asterodinium gracile Sournia, Microceratium orstomii Sournia and the toxic species Karenia papilionacea Haywood et Steidinger have been investigated in open waters of the SE Pacific Ocean. The genus Microceratium Sournia is recorded for the first time since the initial description. These taxa showed a high morphological similarity and they may correspond to life stages of a highly versatile single species that is able to project body extensions. Karenia papilionacea showed the higher abundance in the surface waters of the more productive areas (the Marquesas Archipelago and the Perú-Chile Current). Brachidinium capitatum and K. papilionacea often co-occurred, predominating B. capitatum in offshore surface waters. Asterodinium gracile was recorded at the bottom of the euphotic zone (down to 210 m depth), with a shallower distribution in more productive areas. Intermediate specimens of Asterodinium-Brachidinium-Karenia, with variable disposition and size of the body extensions were illustrated.

This paper reviews various models of technological innovations at different levels: project level and productive segment level. Firstly, it examines a number of significant factors influencing the success and failure of technological innovation at project level. Specifically, the role and characteristics of technical information for the success of innovation is analyzed. Secondly, the paper discusses in detail the relationship between technological innovation and the evolution of a firm. Product and process innovations are analyzed in accordance with a three stage model; the stages are performance maximizing (uncoordinated), sales maximizing (segmental) and cost minimizing (systemic). Various implications of the model are presented in terms of the business policy variables such as diversification, standardization, productivity improvement, marketing, etc. The applicability of the model to a developing country is sought and a few suggestions to develop new model of technological innovations in LDC are discussed.

In a basic engineering design class, first year engineering department students learn about engineering design relevant theories and carry out simple projects in teams. By doing a group project in this subject, students develop basic skills such as creativity, teamwork, communication, and problem solving. Before, class proceeded in a way where teams were randomly configured in the beginning of semester and students began working on their project immediately. However, this research introduces a new method where at the beginning of the semester, students are assigned group assignments. Teammates are randomly chosen and constantly switched so that students get a chance to work with different people and experience diverse styles and characteristics. Then, they autonomously form into teams with people they work best and carry out their project. We present the behavior of a monkey robot that recognizes emotions as a case of applying the proposed method. The feedback from the students suggest that this proposed team forming method serves to be effective especially since students who were not aware of other students' characteristics can get to know one another better and form a productive team.

Statistical thinking has a broad definition but focuses on the context of regression modelling in the present study. To foster students' statistical thinking within the context, teaching should no longer be seen as transfer of knowledge from teacher to students but as a process of engaging with learning activities in which they develop ownership of knowledge. This study aims at collaborative learning contexts; students were divided into small groups in order to increase opportunities for peer collaboration. Each group of students was asked to do a regression project after class. Through doing the project, they learnt to organize and connect previously accrued piecemeal statistical knowledge in an integrated manner. They could also clarify misunderstandings and solve problems through verbal exchanges among themselves. They gave a clear and lucid account of the model they had built and showed collaborative interactions when presenting their projects in front of class. A survey was conducted to solicit their feedback on how peer collaboration would facilitate learning of statistics. Almost all students found their interaction with their peers productive; they focused on the development of statistical thinking with concerted effort.

Data from 22837 lambings of Lohi and Kajli ewes from 1962 through 1994 were used to analyse productive and reproductive traits and wool production, Overall litter size at birth averaged 1.33 being 1.45 for Lohi and 1.21 for Kajli ewes. The corresponding values at weaning were 1.23, 1.32 and 1.14, respectively. Litter size was consistently lowest for one year old, with a substantial increase at two, three and four years of ewe age and marginal increase thereafter, Ewes lambing in spring weaned 0.08 more lambs per parturition than ewes lambed in Autumn (p<0,01). Lamb birth weights were affected by ewe breed (p<0.01) and increased with ewe age. Overall lamb weaning weight (120 d) of 17993 lambs was 20.3 kg. Weaning weight was affected by breed, sire, year of birth, sex, rearing rank and weaning age (p<0.01). The highest mean weaning weight was 21.9 kg for Lohi lambs followed by Kajli lambs (18.8 kg), Lambs from Kajli ewes were 9% heavier at birth but 14% lighter at weaning. Twin born lambs were 18% lighter at birth and 13% at weaning than single born lambs. Male lambs were 3% heavier at birth and 4.5% heavier at weaning than female lambs. Overall annual mean wool production was 2,64 kg, Kajli ewes were heavier at breeding than Lohi ewes (i.e. 46.2 vs 44.8 kg). Lohi ewes being 3% less body weight produced 38% more wool and 18% more litter weaning weight than Kajli ewes, When average weight of lamb weaned per ewe weaning lambs was adjusted for ewe average metabolic body size, Lohi ewes were most efficient (i.e. arbitrary assigned value of 100) compared to Kajli ewes achieving only 83% of Lohi level.

This study examined the effect of behavior on leader' s impersonal behavior and organizational members 'semi - productive task and the moderating effect of organizational support perception. As a result of conducting a questionnaire survey on SMEs of auto parts industry in Chungnam, Sejong, and Daejeon, the non-personality behaviors of the top leaders had a significant effect on the non-personality behaviors of the middle leaders (p <.001, ${\beta}=.910$). The results of this study are as follows. First, the relationship between the leader and the supervisor was significantly influenced by the non-personality behaviors. In addition, higher leaders have a moderating effect on negative behaviors and semi-productive task behaviors toward the organization of members. The control effect of semi - productive task behavior was confirmed. The results of this study provide suggestions for reducing economic loss and social loss due to semi-productive task behavior of organizational members by revealing the phenomenon of non-personality behavior of middle leader to non-personality behavior of upper leader.

Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.
