In this paper, we identify risk factors that are likely to occur during the lifecycle of a new product development (NPD) project from the literatures, and identify the three objectives or three constraints that will ultimately be achieved for project success in the ICT industry : performance (scope/quality), schedule (time), and cost. Firstly, we interviewed the project experts to classify the risk factors according that the final project objectives are changeable based on scope/quality, time and cost budget constraints. Secondly, the survey for pairwise comparisons between the risk factors was asked to the project managers and members who had ever actually participated in the NPD projects of ICT industry to determine the priority ranks on relative importance using AHP (Analytic Hierarchy Process). The risk factors negatively affecting the goals of projects were analyzed by using the AHP respectively in four project stages during the life cycle of the project. The comparison of risk factors within each stage is a different approach unlike the literatures which have covered project's overall risk assessment. There is an advantage that risk management can be effectively performed with priorities according to each stage from the start to the end of the project. In other words, it is necessary to identify what risk factors will occur in each stage, and to have ideas at each stage with the priorities so that they can be mitigated and eliminated before actual occurrence. As a result, risks on scope & quality changes were found to be the most important considerations for initiative stage of NPD projects in the ICT industry, whereas in the final stage, risks on schedule (time) changes were the most important priorities. Among the ICT industry product categories, 'communication and broadcasting devices' and 'IT and communication based devices' generally have a high priority in terms of risks on scope & quality changes when initiating the project. At the closing stage of the project, however, considering that schedule (time) changeable risk is getting higher, these products tend to target at B2B market rather than B2C because the new products must be delivered and launched in time as customer firm required.

많은 엔젤 투자자들이 초기단계기업에 투자하는 것을 주저하고 있다. 초기단계기업은 대부분 매출이 없고, 개발단계이거나 시장진입초기단계인 경우가 많아서 기업 가치를 정량적으로 평가할 수 없기 때문이다. 따라서 엔젤 투자자들이 기업을 평가하고 투자의사를 결정하는 경우 기업가의 성향에 의존 할 수밖에 없는 경우가 많다. 이에 본 연구는 엔젤 투자자의 투자의사결정요인에 영향을 주는 기업가적 특성의 요인과 그 중요도를 도출하였다. 연구방법은 엔젤 투자클럽, 벤처캐피털리스트, 기업 대표 및 임원 등의 엔젤 투자자 전문가 그룹 20인을 선정하여 델파이 기법(Delphi Technique)에 따라 설문조사를 실시하였다. 3차에 걸친 조사 결과 투자의사결정요인 중에서 기업가적 특성에 해당하는 요인으로 신뢰성, 위험감수성, 열정, 인내력, 진실성, 리더십, 창업경험, 조직관리능력, 혁신성, 인맥(네트워크)의 10개의 요소들을 도출하였다. 또한 도출된 기업가적 특성 요소의 중요도를 분석하기 위하여 AHP(Analytic Hierarchy Process) 이론에 근거하여 각 요소에 대한 쌍대비교(Pair-wise Comparison)를 통하여, 그 중요도를 분석한 결과 신뢰성(18.1%), 진실성(15.9%), 리더십(11.7%), 조직관리능력(10.0%), 인맥(네트워크)(9.5%), 열정(9.1%), 인내력(8.4%), 혁신성(8.1%), 창업경험(5.3%), 위험감수성(3.9%)의 순으로 나타났다. 본 연구는 의의는 투자자의 투자 의사 결정에 영향을 주는 요인들 중에서 초기 단계의 기업에 가장 큰 영향 요인이라 할 수 있는 기업가적 특성 요인을 도출하여 중요도를 비교함으로써 엔젤 투자의 불확실성으로 인하여 생기는 한계를 다소나마 줄이고, 엔젤 투자자의 판단에 도움을 줄 수 있다는 점이다.

Genome-wise association studies (GWASs) have become popular approaches to identify genetic variants associated with human biological traits. In this study, we applied Structural Equation Models (SEMs) in order to model complex relationships between genetic networks and traits as risk factors. SEMs allow us to achieve a better understanding of biological mechanisms through identifying greater numbers of genes and pathways that are associated with a set of traits and the relationship among them. For efficient SEM analysis for GWASs, we developed a procedure, comprised of four stages. In the first stage, we conducted single-SNP analysis using regression models, where age, sex, and recruited area were included as adjusting covariates. In the second stage, Fisher's combination test was conducted for each gene to detect significant genes using p-values obtained from the single-SNP analysis. In the third stage, Fisher's exact test was adopted to determine which biological pathways were enriched with significant SNPs. Finally, based on a pathway that was associated with the four traits in common, a SEM was fit to model a causal relationship among the genetic factors and traits. We applied our SEM model to GWAS data with four central obesity related traits: suprailiac and subscapular measures for upper body fat, BMI, and hypertension. Study subjects were collected from two Korean cohort regions. After quality control, 327,872 SNPs for 8842 individuals were included in the analysis. After comparing two SEMs, we concluded that suprailiac and subscapular measures may indirectly affect hypertension susceptibility by influencing BMI. In conclusion, our analysis demonstrates that SEMs provide a better understanding of biological mechanisms by identifying greater numbers of genes and pathways.

Background: The Pakistan Atomic Energy Commission Cancer Registry (PAECCR) program has made availability of a common cancer incidence database possible in Pakistan. The cancer incidence data from nuclear medicine and oncology institutes were gathered and presented. Materials and Methods: The cancer incidence data for the last 30 years (1984-2014) are included to describe a data set of male and female patients. The data analysis concerning occurrence, trends of common cancers in male and female patients, stage-wise distribution, and mortality/follow-up cases is also incorporated for the last 10 years (2004-2014). Results: The total population of provincial capital Lahore is 9,800,000. The total number of cancer cases was 80,390 (males 32,156, females 48,134). The crude incidence rates in PAECCR areas were 580.8/$10^5$ during 2010 to 885.4/$10^5$ in 2014 (males 354.1/$10^5$, females 530.1/$10^5$). The cancer incidence rates for head and neck (15.70%), brain tumors (10.5%), and non-Hodgkin lymphoma (NHL, 9.53%) were found to be the highest in male patients, whereas breast cancer (46.7%), ovary tumors (6.80%), and cervix (6.31%) cancer incidence rates were observed to be the most common in female patients. The age range distribution of diagnosed and treated patients in conjunction with the percentage contribution of cancer patients from 15 different cities of Punjab province treated at the Institute of Nuclear Medicine and Oncology, Lahore are also included. Leukemia was found to be the most common cancer for the age group of 1-12 years. It has been identified that the maximum number of diagnosed cases were found in the age range of 51-60 years for males and 41-50 years for female cancer patients. Conclusions: Overall cancer incidence of the thirty years demonstrated that head and neck and breast cancers in males and in females respectively are the most common cancers in Punjab province in Pakistan, at rates almost the highest in Asia, requiring especial attention. The incidence of brain, NHL, and prostate cancers among males and ovarian and cervix cancers among females have increased rapidly. These data from a major population of Punjab province should be helpful for implementation of appropriate planning, prevention and cancer control measures and for determination of risk factors within the country.
