This paper presents a process and operation planning system with an NC code post-processor for effective machining of press dies for production of cars. Based on the machining features, major parts of press dies are categorized into 15 groups and a standard process plan is defined for each group. The standard process plan consists of a series of processes where a process is defined as a group of operations that can be done with one setup. Details such as cutting tools, cutting conditions, and tool paths are decided at the operation planning stage. At the final stage of process and operation planning, the NC code post-processor we developed adjusts feedrates along the tool path to reduce machining time. The adjustment rule is selected based on the metal removal rate estimated by virtually machining with virtual cutting tool.

SK group has been a pioneer in overall brand management and, more recently, in CSR-imbedded brand management. SK vision of "improving itself to give greater happiness to all of its customers" and the symbol mark of "Wings of Happiness" are some good examples of integrating distinct brand identities of various member companies. After impressive growth and expansions into diverse business areas, SK group is ranked as the third largest company based on asset amounts according to the Fair Trade Commission of Korea, only after Samsung and Hyundai Motor groups. SK brand management can be analyzed, using the framework of 4 stages - 'infrastructure', 'planning', 'doing', and 'seeing' stages. In order to secure 'infrastructure' of brand management system, SK has invested huge resources to the 'SK BMS' (SK Brand Management System). At the 'planning' stage, the most important task of SK like other Korean business groups is perhaps to adopt a well-organized 'brand identity (BI) system' which may consolidate brand values of individual member companies. In actuality, SK BI consists of Customer Happiness located at the center and 3 other elements of Pride, Professionalism, and Customer-orientation. At the 'doing' stage, the slogan of 'OK! SK' and the logo of 'Wings of Happiness' have been placed at the core of the SK group brand building programs. SK adopts the principle of 'independent yet united', pinpointing that each member company independently works for its business performance but it is, at the same time, encouraged to integrate its capabilities for the SK group brand. In addition, SK has sought 'shared growth' with business partners for happiness for all the members in the society. 'Social Contribution Philosophy' based on SK value of 'creation of greater happiness' is again one of the most important guidelines for CSR (corporate social responsibility) at the doing stage. At the seeing stage, SK regularly evaluates its branding programs. SK has shown some very impressive achievements in brand management: (1) a core identity of 'Customer Happiness' participating member companies may share, (2) harmonious relationships between the group brand management office and brand management divisions of member companies, and (3) consistency-keeping in brand management over time. However, there remain two major challenges: (1) globalization of SK and (2) reinforcing sustainable superiority over not only Korean rivals but also global ones.

Ilizarov limb lengthening has been the new method to deal with a variety of orthopaedic problems. Ilizarov apparatus consists of stainless steel rings that surround the limb and are interconnected by threaded rods. Tensioned wires pierce the bone in the plane of each ring and are tightly attached to the ring. Ilizarov has reported distraction osteogenesis with the use of the typical fixator that allows functional loading. The purpose of this commentary is to introduce a four-stage rehabilitation protocol currently used by the authors in the physical therapy management of a post -limb lengthening. Each treament stage corresponds to a medical stage in the lengthening process. Treatment goals for each of the physical therapy treatment stage are presented to guide treatment planning. Two case examples are presented to illustrate the use of the management goals in treatment planning.

When planning buildings, safety should be considered as a priority over any other performance. The study aims to derive and systematize elements that can be reflected in the design stage, which affects the safety of construction workers and building users. The elements for safety of workers are classified by type of work, and the elements for safety of users are classified by fields. Elements that are difficult to be reflected in design stage or those whose effects are insignificant are excluded. In addition, application scenarios have been proposed for each element so that the elements created in this study can be directly applied and utilized in practice. This will contribute to lowering the accident rate of construction projects by evaluating the harmful risks of construction projects at the design stage.

건설사업관리 업무를 수행하는데 있어 설계이전단계인 사업기획단계, 기본설계 및 실시설계단계가 시공단계보다 중요한 비중을 차지하고 있다. 그러나 건설기술관리법상 건설사업관리 대가 기준으로 본 인력투입기준은 설계이전단계의 중요성을 고려하지 않고 있는 실정이다. 이러한 현실적 상황에 따라 본 연구에서는 건설사업관리 업무의 설계이전단계 인력투입 적정성을 분석하여 개선방안을 제시하는 것을 목적으로 건기법의 용역대가기준과 건설사업관리 용역 4곳의 현장을 비교 분석 하였다. 연구결과 사업수행에 있어 개선된 인력투입의 적정성 분석은 다음과 같이 나타났다. 1)실제 건설사업관리 용역의 단계별 대가평균기준의 인력투입현황을 사업기획단계 신설(6.6%), 기본설계단계(3.9%$\rightarrow$5.6%), 실시설계단계(7.6%$\rightarrow$13.5%), 시공단계(88.5%$\rightarrow$64.0%), 유지관리단계 신설(10.3%)로 제안하였다. 제안된 대가평균기준을 총공사비 기준으로 분류하여 개선후의 요율과 단계별로 산정하여 제시하였다. 2) 건설기술관리법 기준인 3단계기준을 사업기획단계, 유지관리단계를 포함하여 단계별 업무를 구분하여 5단계로 제시하였다. 이와 같은 결과는 건설사업관리 용역현장의 대가 표준 산정이 현실적이고 탄력적으로 운용되고 단계별 인력투입에 대한 제도개선이 현실적으로 이루어져야하는 것으로 볼 수 있다.

The purposes of this study were to analyze chemistry problem solving processes of middle school students and to compare their problem solving behaviors in the aspects of the cognitive developmental level of student, the success in problem solving, and the context of problem. Their failures in solving problems were also analyzed in the aspects of problem solving stage and prior knowledge. Forty-two students individually solved four problems regarding density and solubility using a think-aloud method. Students' responses were analyzed after intercoder agreement for analyzing problem-solving processes had been established to be 0.94. The results were as follows: 1. Most students solved chemistry problems following the stages of understanding, planning, and solving, while few exhibited the behaviors of the reviewing stage. There was also individual difference in the number of the stages repeated and their behaviors at each stage. 2. Most students were successful in understanding problems. However, unsuccessful and/or concrete-operational students had more difficulties in understanding problems than successful and/or formal-operational students, and students tended to have more difficulties in understanding problems in everyday contexts than in scientific contexts. 3. Successful and/or formal-operational students exhibited more behaviors of the planning stage than unsuccessful and/or concrete-operational students. Students showed more behaviors of the planning stage, but failed more at this stage, in everyday contexts than in scientific contexts. 4. Most students did not review their solutions. Successful and/or formal-operational students exhibited these behaviors more than unsuccessful and/or concrete-operational students. Students tended to exhibit the behaviors more in everyday contexts than in scientific contexts. 5. Many students failed to solve problems correctly due to the lack of prior knowledge and the inability to plan appropriately.

In this study, SWMM model is used to reproduce the main storm sewer system located in the Nae-Hang drainage basin of the Mokpo city and keep track of flood discharge. Given the outlet of the reaches border the coastline, this paper has taken the dual-drainage approach to perform inundation simulation, considering both the overflows and inflows at the manholes of the sewer system, and at the same time, taking the impacts of tidal stage into consideration. The following conclusions are reached in this study: First, when planning lowland sewer system alongside the coastline or the riverside, the tidal stage or flood stage need to be considered in the planning and design processes. Second, an analysis that fails to consider overflow and inundation at the manholes may overestimate inundation depth of the flooded area. In other words, in order to estimate flood discharge and flood stage in a lowland storm sewer system, it is desirable to analyze the conveyance capacity of storm sewer system and simulate overflow and inundation at the manholes at the same time.
