  • 해삼은 고형분의 50% 이상이 단백질이며, 그 외 기능성 물질로써 사포닌, 뮤코다당류 등 다양한 생리활성 물질들을 보유하고 있다. 해삼 성분을 미생물의 효소로써 분해하기 위해 Bacillus 및 유산균 유래 각종 효소의 활성을 분석하였다. 분석된 균주 중에서, B. subtilis K26은 protease의 활성과 xylanase의 활성이 가장 높았으며, cellulase의 활성도 비교적 높은 것으로 나타났다. 따라서 해삼과 정제수를 동일 비율로 혼합하고 멸균한 후 B. subtilis K26를 접종하여 발효를 실시하였다. 그 결과 1.5-7.5시간에서 가장 높은 잔존 아미노산의 함량이 평가되었으며, 잔류고형분도 비교적 낮게 나타났고, 발효취도 적게 나타났다. 발효해삼분말을 부탄올로 추출하여 사포닌 함량을 측정한 결과 1.12 mg/g로 나타났다. Chondroichin sulfate 함량은 5.11 mg/g 생해삼으로 평가되었으며, 총 폴리페놀 함량은 6.95 mg gallic acid equivalent/g 생해삼, 총 플라보노이드 함량은 3.69 mg quercetin equivalent/g 생해삼 등으로 평가되었다. 발효해삼의 항산화효능은 0.59 mg ascorbic acid equivalent/g 생해삼으로 항산화능력이 우수한 것으로 평가되었다. 다른 한편으로 발효해삼액의 DNA 손상 보호효과는 발효액의 농도 의존적으로 생성되었으며, 매우 저 농도에서 매우 우수한 효과가 있는 것으로 평가되었다. 이상의 결과로 볼 때, 해삼발효액은 아미노산, 사포닌, 페놀류, 콘드로이친 황산, 플라보노이드류 등에 기인하여 우수한 항산화능력과 DNA 손상 방지능력이 있는 것으로 제의된다. 따라서, B. subtilis K26의 발효해삼액은 인체에 있어서 산화억제, 면역증강 및 근 개선 식품으로 가능성이 높은 것으로 추정된다.

  • 백조는 신의 전령사로 여길 만큼 서조이자 귀중한 겨울 철새이다. 백조도래지는 처음 천연기념물로 지정될만큼 중요한 역사적 의미를 지닌다. 본 연구에서는 천연기념물로 지정된 합천 백조도래지에 대한 지정과 해제과정을 살펴보고자 했다. 합천 백조도래지는 지정 이전에 있었던 역사적 사실이 영향을 끼쳤다고 판단된다. 일제강점기인 1929년 일본왕에게 새해 인사로 합천군 용주면에서 생포한 백조를 진상하였던 것이 계기가 아니었을까 한다. 이러한 사실은 5여 년 뒤 천연기념물을 지정할 때, 합천 백조도래지 선정에 긍정적으로 작용하였을 것으로 추론된다. 합천 백조도래지는 1934년 8월 27일, 처음 우리나라 천연기념물로 지정되었다. 그 흔적으로 용주면 해곡마을 입구에는 일제강점기 조선 총독부에서 만든 석표가 유물로 남아 있다. 이러한 천연기념물 합천 백조도래지는 1973년 8월 14일 해제되었다. 전쟁과 다양한 개발을 통한 과도한 인간의 간섭, 불법 포획, 그리고 그들을 잡기 위한 독극물 사용으로 인해 겨울 철새의 개체수가 급격히 줄어들어 백조도래지의 기능을 상실하였기 때문이다. 천연기념물 지정 당시 합천군 백조도래지는 3개소였다. 청덕면 가호(嘉湖)는 완전히 매립되어 사라져 농지로 전환되었고, 용주면 박곡지(朴谷池)는 상류의 댐 건설로 인해 습지가 사라져 가고 있으며, 대양면 정양지(正陽池)만이 습지가 존속되면서 백조 등 겨울 철새가 날아들고 있어 많은 시사점을 남기고 있다.

  • 본 연구는 가맹사업자의 자기효능감에 주목하여 정부가 예비가맹사업자들을 보호하기 위해 가맹본부에 다양한 규제와 정책을 사용하는 것이 최선의 방법이 아니라는 것에 관심을 두고 있다. 본 연구에서는 경로-목표이론(path-goal theory)에서 제시한 가맹본부의 리더십 행동 유형과 가맹사업자의 관계결속의 영향관계에 있어서 가맹사업자의 특성으로 자기효능감의 조절효과를 규명하고, 실증 분석한 결과 다음과 같은 연구의 시사점을 발견할 수 있었다. 첫째, 가맹본부의 리더십 행동유형이 관계결속에 긍정적 효과를 가져 온다는 사실이 확인됨으로써 가맹본부는 가맹사업자에게 맞는 리더십 행동유형을 적용할 수 있도록 하여야 한다. 둘째, 가맹사업자의 자기효능감이 관계결속에 긍정적 효과가 있을 뿐만 아니라, 리더십 행동유형과 관계결속 사이에 상당한 조절효과가 있기 때문에 가맹본부는 가맹사업자들의 개인차(individual difference) 관리가 필요하다. 셋째, 정부는 가맹본부를 규제할 것만이 아니라 가맹본부가 가맹사업자들의 특성을 확실하게 파악하고 기업의 목표달성을 위한 정당한 통제가 가능하도록 제도적 지원을 해야 할 것이다.
