The central focus of this research paper is to enlarge the spectrum for manpower projection methodology and practical policy use. This study considers to have accurate creation and generation of statistic indices and information about education and labor in the construction of human resources development policies system.Given this necessity, manpower demand & supply estimation is a very important issue for basic HRD policy. Such estimation methodologies are mainly divided into 2 ways of quantity and quality, the one is model specification technique and the other is market signaling technique. These 2 ways have been debated on usefulness. Because the objective of the model specification technique is to estimate the precisive number of manpower, it has the advantage of being transparent.And then this study tried to link model specification technique with market signaling technique to evaluate the credibility of the outcome. However, this linking trial study is only a first step and, because it had limited data and any other problems, future studies need to be undertaken continuously are necessary to link quality with quantity estimation.Finally this study suggested policy issues for human resources development. This study placed a particular emphasis on higher education policy which was the fixed capacity number coordination issue.

The susceptibility values for field‐collected (BG‐BG) and laboratory (KS‐BG) strains of German cockroaches (BS‐BG), Blattella germanica (L.) to five synthetic pyrethroid and three organophosphate insecticides were assessed by topical application. Both KS‐BG and BS‐BG strains demonstrated the highest levels of susceptibility to deltamethrin with LD50 values of 0.0035 μg/female and 1.5744 μg/female, respectively. The KS‐BG strain demonstrated the lowest susceptibility level to fenthion with an LD50 value of 0.0698 μg/female, while the BS‐BG field population showed the lowest susceptibility to bifenthrin with 4.6811 μg/female. The BS‐BG field population showed resistance levels of 50 to 640 fold higher against the eight pesticides evaluated compared to the KS‐BG strain. The resistance ratios (RR) of the eight pesticides were compared using populations of B. germanica that were collected from the same locality during 2007 and 2014. The field population of B. germanica collected during 2014 demonstrated significantly high resistance to an organophosphates and all pyrethroids when compared with those collected during 2007, but RR values were <10 except for chlorpyrifos‐methyl and chlorpyrifos with RR values of 74 and 104, respectively.
