This study estimates the classification criteria which distinguishes the types of omega-3 health functional foods, fish oils and fish oil usages through 13C-NMR spectra and fatty acids contents analysis. The major fatty acids of omega-3, eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6) are being analyzed. 10 ethyl ester (EE) forms and 10 triglyceride (TG) forms are the most common types of fish oils for 20 omega-3 products. Gas chromatography (GC) analysis generally shows the matching EPA and DHA contents of the products listed on the notation. But EE form contents of EPA and DHA are higher and are more varied than the TG form. Most of the samples of EPA/DHA ratio show different content ratios of indicated on the products when comparing with standards. The 13C-NMR analysis of EPA and DHA on sn-1,3 and sn-2 carbonyl peak position with fish oil triglycerides display whether the reconstituted triglycerides (rTG) are being confirmed or not. As a result of the 9 TG form, the 10 TG products showed similar values: EPA sn-1, 3; 13.46~15.66, sn-2; 3.00~4.52, DHA sn-1, 3; 2.43~4.40, sn-2; 3.84~6.36. But one product showed lower contents (EPA: sn-1, 3; 5.88, sn-2; 2.86, DHA sn-1, 3; 2.29, sn-2; 5.95) of EPA, thus it can be considered a different type of oil and only matched six products according to the label. This study is intended to provide basic materials which identify the status for the types and quality of omega-3 fish oil products according to fatty acids profiles and the 13C-NMR spectrum confirmed the location specificity of EPA and DHA.

4'-formylbenzo-15-crown-5와 RHD, RED의 반응에 의해 새로운 두 종류의 크라운 에테르 RHDC 와REDC를 합성하였다. RHD, RED는 로다민 6G와 hydrazine, ethylenediamine을 이용하여 합성하였다.합성된 화합물들에 여러 가지 금속 양이온을 첨가하여 선택적인 형광 인식 특성을 알아보고, 형광 센서로서의 가능성에 대해 검토하였다. 합성된 화합물의 금속 인식 특성을 형광스펙트럼으로 측정한 결과 형광이 증가하였으며 Fe3+ 대한 인식이 가장 좋았다.

In an industrial Era, OJT(On-the-Job Training) has been accepted as the field learning. But in a breaking up era, traditional field training needs to change and make an evolutionary model. Also, we need to make evolutionary model for various changing ways and means and need means to maximize the transformation of learning by operating learning organization. In knowledge based society, as people work and learn new knowledge in order to pass the experience knowledge and capabilities, they are not the traditional relationship between trainer and trainee but maximize work and learning, development and performance through several different ways. So, the study about new learning model is needed because the learning is creating the value and makes low cost and high efficiency about the elements of cost and time. We study the evolutionary model, OJF(On-the-Job Facilitating) - new learning methodology - through operating learning organization in S Electronics and its application practices.

Citrus계 식용 코팅제인 beeswax-hydroxypropyl methylcellulose(BW-HPMC), soybean oil-carboxymethyl cellulose(SBO-CMC), carnaubawax-shellac-locust bean gum(CW-SL-LBG)를 각각 사용하여 레몬에 먼저 1차 코팅하고 항산화제인 비타민 C와 E를 섞어 그 위에 제 2차 코팅하여 이중층의 multilayered 레몬을 제조하였다. 레몬 껍질 위에 형성된 막의 양은 CW-SL-LBG, BW-HPMC, SBOCMC의 순으로 높게 나타났다. 가속 저장 실험 조건으로 30oC의 항온기에 12일 동안 저장하면서 유자의 중량감소율, 부패율, 경도, pH, 가용성 고형분, 적정산도, 갈변도의 변화를 측정하고 관능검사를 실시하였다. 중량감소율, 부패율, 경도, 갈변도는 CW-SL-LBG가 가장 작은 변화를 보였고, pH, 가용성 고형분, 적정산도의 변화는 SBO-CMC가 가장 작게 나타났다. 저장성의 관능검사에서는 CW-SL-LBG가 가장 양호하게 나타났다. 결과적으로 CW-SL-LBG가 비타민 C와 E를 함유한 multilayer 코팅에 가장 적합한 물질로 평가되었다.

The object of this paper is established for a paradigm for the organization. Although concerns on management get increased in these days, there is no general and systematic framework for a unified sector. Therefore this study proposes the new general and systematic framework for managing in organization, through applying Service-Engineering model. The new framework of this study provides the general sector of organization model, the method of analyzing BSC and RMS, and system model for Risk Management. Furthermore, this study suggests the practical ways of developing a paradigm.
