This paper presents a case study on BSC(Balanced Scorecard) system development of Korea Post as a Korean public firm. BSC models of public or private sector are generally developed in different types due to their different strategic goals. Korea Post as a government firm has dual characteristics of BSC similar to both public and private sector. This firm has the organizational type of public firms, not private firms. To date many government subsidiary organizations have already introduced BSC or are trying to introduce BSC, but have difficulty in developing BSC successfully because of insufficient understanding of BSC. Based on a case study of Korea Post, this study analyzed key success and failure factors and suggested prospects on BSC system development of public firms.

Parallel processing algorithms, coupled with advanced networking and distributed computing architectures, improve the overall computational performance, dependability, and versatility of a digital signal processing system In this paper, novel parallel algorithms are introduced and investigated for advanced sonar algorithm, conventional matched-field processing (CMFP). Based on a specific domain, each parallel algorithm decomposes the sequential workload in order to obtain scalable parallel speedup. Depending on the processing requirement of the algorithm, the computational performance of the parallel algorithm reveals different characteristics. The high-complexity algorithm, CMFP shows scalable parallel performance on the array of DSP processors. The impact on parallel performance due to workload balancing, communication scheme, algorithm complexity, processor speed, network performance, and testbed configuration is explored.

The Analytic Hierarchy Process (AHP) has been widely used as a comprehensive evaluation method since it can include various evaluation standards of both the public and private sectors. It also provides the objective mathematics to process subjective and Personal preferences of an individual or a group in making a decision. This study tried to use AHP to determine the priority of roads investment, considering various effects in a hierarchy such as environmental effects, residential life, and regional development which has not been treated explicitly. As a case study, roads in Gyeongsangbukdo province have been chosen for the evaluation in this research. For the application, it used relative measurements to estimate the weight of upper level structure, and absolute measurement for low level structure instead of pairwise comparisons.

세계화 추세의 가속, 급속한 기술진보 및 정보화의 확산 등은 국제간의 분업구조 뿐만 아니라 국내의 산업구조 및 취업구조를 급격히 변화시키고 있다. 국내 취업구조의 변화는 산업간 직업간 취업비중을 모두 변화시키고 있어 고용의 양적 측면은 물론이고 질적 측면에서도 큰 변화가 예상된다. 그러므로 중장기적인 노동력수요 예측은 향후 인력양성의 방향과 체계를 결정하는 데 중요한 지표가 될 뿐만 아니라 노동시장 정책에 있어서도 반드시 필요한 자료가 되고 있다. 따라서 본 연구에서는 향후 노동력에 대한 중장기 수요를 일반균형적인 접근을 통하여 산업별 직업별로 예측하고 이 예측결과에 따른 향후 노동시장 및 인력정책의 방향을 제시하는 데 있다. 본 연구에서는 기존의 연구들이 사용한 방법의 이론적 약점을 보완하면서 실증 결과의 예측성을 높일 수 있는 개선된 방법을 사용하였다. 산업별 취업자를 전망하는데 있어 기존 연구결과들은 주로 노동시장의 단일방정식만을 추정함으로써 생산요소의 수요가 비탄력적이지 않음에도 불구하고 생산요소간의 대체가능성을 무시하고 있으며, 인력수요에 중요한 결정 요인인 기술변화를 고려하지 못하고 있거나, 취업계수의 변화를 통해 기술진보의 효과를 고려한다고 하여도 기술진보가 생산요소간에 비중립적(factor non-neutral technology changes)으로 일어날 경우 요소간 대체가능성을 간과하고있다. 이러한 단점을 보완하기 위해 본 연구에서는 산업별 취업자 전망에서 노동시장의 단일방정식 추정이 아닌 일반균형에 입각한 경제 모형을 사용하였다. 또한 직종별 취업자 전망을 위해서는 일반적으로 이용되는 필요 인력량에 대한 고정계수(fixed coefficient manpower requirement)를 추정할 때 이중비례행렬모형(二重比例行列模型)을 이용하여, 산업구조의 변화로 인한 직업별 인력수요 변화가 충분히 고려되도록 하였다. 전망의 결과에 따르면 향후 우리 경제는 지식기반경제(knowledge-based economy)로 이행하고 있다고 볼 수 있다. 우선 산업구조면에서 지식집약적산업으로의 구조조정이 일어나게 되고 이에 따라 산업별 취업구조에서도 고기술산업의 취업준비중이 급속히 증가하게 된다. 직업별 취업분포에 있어서도 전문기술직 행정관리직 등의 고숙련 사무직의 비중은 크게 증가하는 반면 생산관련직과 농림어업직의 비중은 감소하게 된다. 이처럼 경제가 지식집약화되어 감에 따라 고학력자에 대한 수요는 지속적으로 증가하지만 현재 적절한 인력양성과 공급이 이루어지지 않고 있어 향후 기술이나 기능에 따른 수급부일정(需給不一政)(skill mismatch)현상이 매우 심해질 것으로 보인다. 따라서 앞으로의 인력정책에서 가장 주안점을 두어야 할 부분은 첨단기술산업과 관련된 인력의 양성에 있다고 하겠다.

The construction industry has mainly relied on financially focused performance measurements, and studies on performance measurement systems (PMSs) have been carried out at the project level. However, recently, the demand for performance evaluation and management at the company level has increased. A few previous efforts have aimed to develop a conceptual model for company performance, but there have been few follow-up studies. From this perspective, we have developed a web-based performance and informatization measurement system to measure and compare the business performance and the level of informatization of construction companies. Then, we carried out a performance evaluation and system test using the data set of 78 Korean construction companies and identified practical issues for the implementation of our PMS.

The increases of industrial and technological development and human activities have disturbed the balance of natural nitrogen (N) circulation. These phenomena have induced that large amounts of N are to be present in excess in air, soil and water environment. We investigated the effects of excess of reactive nitrogen ($N_r$) compounds on soil and water environment ecosystems through literature and case studies, and suggested the strategy of mitigating the acidification in soil and water ecosystems. $N_r$ moves to air, soil and water media, can be converted to different types, and interacts with other chemical compounds. As an efficient N management plan, the evaluation (application of monitoring and safety index) and the chemical restoration (research and development) of the acidification in soil and water environment ecosystems are required to minimize the effects of $N_r$ as well as policies to regulate the various emission sources and amounts of $N_r$.

Bone undergoes continuous remodeling throughout the life and bone health is governed by the balance of bone resorbing osteoclast and bone forming osteoblast. Bone resorption is reflected in tartrate resistant acid phosphatase, pyridinium cross link and collagen telopeptide, whereas bone formation activity can be expressed as bone specific alkaline phosphatase, osteocalcin and procollagen I extension peptide. Milk basic protein and lactoferrin have been reported as active proteins to modulating bone metabolism. In addition to these proteins, some bioactive milk peptides released during lactic fermentation may provide beneficial effect on bone metabolism. The effects of fermented products of Lactobacillus casei ATCC 393 on bone metabolism were investigated using a variety of biochemical markers in osteoblastic MC3T3-E1 cells and ovariectomized rats. Based on the results, the fermented products of Lactobacillus casei ATCC 393 played an functional role in bone metabolism by suppressing bone resorption and by increasing bone formation.

This research examines performance evaluatees' opinions regarding the institutional performance evaluation systems of Government S&T Research Institutes (GRI). Research methodology is as follows: first, four perspectives of Kaplan & Norton (1992) Balanced Scorecard Model are revised into six perspectives suitable to GRI's characteristics. Second, experts classify current performance evaluation measures into the six perspectives. This enables different evaluation systems of three GRI evaluation groups to be compared under the same evaluation measures. Third, GRI's evaluatees are asked to allocate ideal weights on the performance measures. The evaluatees' weights are compared with the weights of current performance measures, and the characteristics of evaluatees' opinions about current performance evaluation systems are analyzed. Results are as follows; first, six perspectives for Korean GRIs are financial, long-term outcome, short-term outcome, strategic direction, project management, human resources perspectives. second, GRI evaluation systems put the most weights on the long- and short-term outcome perspectives and the least weights on the financial perspective. This result complies with theoretical model: in performance evaluation of GRIs, the customer perspective is the most important one while the financial perspective is the least important one. Third, evaluatees think that the long-term outcome perspective of the Basic-technology GRI group and the short-term outcome perspective of the Applied-technology GRI Group needs more weight. Fourth, it is found that the current systems have more weights on the project management and strategic direction perspectives than evaluatees think. The possible explanation of this result would be that since the measures of these perspectives are relatively easier to set up than those of other perspectives, the current systems contains larger number of measures and, accordingly more weights.
