  • 굼벵이는 각종 작물과 나무에 피해를 줄 뿐만 아니라 특히 골프장 잔디에 피해를 주는 주요해충의 하나이다. 본 연구는 18종의 식물정유(anise oil, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, turpentine)를 이용하여 굼벵이의 환경친화적 방제 가능성을 알아보고자 실내와 온실, 야외에서 실험을 수행하였다. Cap vial실험에서 홈줄풍뎅이 3령충에 효과가 높은 정유는 anise (88.9%)와 linseed oil (100%) 및 tea-tree oil (88.9%)이었다. 온실 pot에서 왜콩풍뎅이 3령충에 대한 anise와 linseed oil의 효과는 낮게 나타났다. 야외에서 anise와 linseed 및 tea-tree oil의 효과도 대상 굼벵이의 종류에 따라 차이를 보였다. 주둥무늬차색풍뎅이 번데기에 대해서는 tea-tree oil 처리에서만 32.6%의 보정사충율을 보였으나 등얼룩풍뎅이 3령충에 대해서는 anise와 linseed, tea-tree oil이 각각 54.8%, 51.6%, 56.5%의 보정사충율을 보였다.

  • 식물 정유로부터 신규 제초제 개발을 위한 살초활성물질을 탐색하였다. 실험에 사용된 10종의 식물정유는[basil(Ocimum basilicum), blackpepper(Piper nigrum), clary sage(Salvia sclarea), ginger(Zingiber pfficinale), hyssop(Hyssopus officinalis), nutmag (Myristica fragrance), palmarosa(Cymbopogon martini), fennel(Foeniculum vulgare), sage(Salvia leucantha), spearmint(Mentha spicta)] 등이었으며, 이중 palmarosa 정유가 유채에 대한 살초력이 가장 높았다($GR_{50}$값, $201{\mu}g\;mL^{-1}$). Palmarosa 정유에 함유된 휘발성 유기화합물로는 alpha-humulene, betacaryophyllen, cis-ocimene, citral, dipentene, geraniol, geranyl acetate, myrcene, nerol, terpinolene, transocimene이었다. Palmarosa 정유에는 geraniol(40.23%), geraniol acetate(15.57%), cis-ocimene(10.79%), beta-caryophyllene(8.72%)이 다량 함유되어 있었고, geraniol과 citral의 $GR_{50}$값은 각각 151과 $224{\mu}g\;mL^{-1}$로 매우 낮았으며 이들 2종의 휘발성 유기화합물이 palmarosa 정유의 살초력에 크게 기여했다고 추론된다. 온실조건에서 palmarosa 정유 $80kg\;ha^{-1}$ 경엽처리는 수수, 돌피, 개밀, 바랭이, 자귀풀, 어저귀, 도꼬마리, 메꽃을 완전 방제하였다. 포장조건에서 민들레, 망초, 쇠비름은 $40kg\;ha^{-1}$ 경엽처리에도 모두 100% 방제가 이루어졌으나 질경이의 방제가는 50% 이었다. 본 연구 결과는 palmarosa 정유에 함유되어 있는 geraniol과 citral이 살초활성에 크게 기여했다는 것을 시사하여 준다.

  • The two existing romanization systems in Korea, namely the recently promulgated Ministry of Education version sponsored by the National Academy of Sciences incorporating for the most part the McCune-Reischauer system and the Hangeul Haghoe or the Korean Language Society's version, must be judged as failures: He fennel for its disregard of Korean orthography and pronunciation, use of Latin-oriented pronunciation despite its assertion that English is the standard used, and the greatest weakness of all, its use of phonetic symbols neither found in regular typewriters, teleprinters, word processors and telex machines nor understood by laymen, sometimes not even by specialists. And the latter suffers from its undue emphasis on Korean orthography, Latin-oriented pronunciation being only partly capable of representing Korean pronunciation, among other shortcomings. Since the two existing romanization systems of Korean in South Korea, and romanization system of Japanese with Latin-oriented pronunciation are woefully inadequate, in today's world where English is used as if it were the international language almost all over the world, the present writer has invented a completely new system of romanizing Korean and Japanese by the so-called pseudo-phonetic method. This method employs the roman letters only and uses thorn in place of phonetic symbols as long as the letters thus applied are believed to have constant sound value. The English pronunciation is the standard used for this system.

  • This study was carried out to get basic information about the morphological and production characteristics of fennel populations different origin under different ecological conditions in Hungary. The Korean population can be registered as a medium high genotype and showed a more accelerated growth characters than Hungarian taxon and the two populations have a medium homogeneity $(CV\;=\;4{\sim}22%)$. In the second year plant height in Hungarian taxon was significantly higher than that of the Korean population. The shooting dynamic of individual plants might be heterogeneous in both taxa and the Korean population was not only shorter in the height but had also less shoots by 16% than the Hungarian one. The Hungarian taxon exceeded the umbel size and numbers to the Korean one (by 3.62 cm in the average) and the variability in the populations was high $(CV\;=\;29{\sim}49%)$. Seed size was proved to be also a discriminative feature between the examined taxa. With small deviations (CV < 2) the Hungarian population produced seeds longer by 38%. Homogeneity in the populations was dependent more on the vegetation years and on the characteristics measured but less on the origins, respectively.

  • The various plant organs of fennel (Foeniculum vulgare Mill.) were investigated to identify their volatile components using Dynamic Headspace (purge & trap). They showed slight differences concerning the volatile components both qualitatively and quantitatively. Results revealed that trans-anethole (12.65%) was the major compound in the leaf. The highest compound was ${\alpha}-pinene$ (28.78%), and trans-anethole (7.90%) was highly detected in the stem. The maximum values were 5.64, 4.59, 1.58, 1.51, and 1.04% for ${\alpha}-pinene,\;{\gamma}-terpinene,\;{\beta}-pinene$, 1,8-cineol and fenchone, respectively in the flower. However, very little trans-anethole was detected (0.27%) in the flower. From these results, it was suggested that the major components were different depending on the plant organs. However it was demonstrated that the related plant organs like flower-fruit and leaf-stem contained the similar components.

  • Algeria is located at the Mediterranean coast of north Africa, 90% of its population is concentrated in the coastal area which is mainly devoted to agriculture. Highland steppe and vast desert climate have determined its food culture. Long arab domination has influenced food of Algeria which has also undergone certain impact of Spanish, Turkish and French occupation. A variety of agricultural products, vegetables, fruits, spices and herbs have determined cooking method and food combination of Algeria. It use neither pork nor alcohol. Its main food consists of bread made from wheat flour and couscous cooked with semoule, Mechuwi, roast lamb and chorba, mixed soup are also typical foods of this region. For climatic reason lamb and chicken are prefered. Energy efficient method is applied to cooking through using oil for saute and water for boiling. Under european influence, Algerian salad used dressing for leaf vegetables, root and other kind vegetables were boiled. Serving with cake and cookies as dessert may possibly be the influence from the French occupation. The cake and cookie are made of wheat flour or other grain flour and take a specific form to be fried sweet with honey. Herbs and spices are widely used in cooking which are easily cultivated in household: mint, basil, rosemary, bayleaf, thyme, sage, fennel, marjoram, coriander, celery. Garlic, onion, piment, red pepper, cinammon are also widely used in an ordinary cooking. Reasonable food combination and economic cooking method could be subject of Algerian food study.

  • Skeletal muscle, essential for metabolism, thermoregulation, and immunity, undergoes myogenic differentiation that results in myotube formation. Trans-anethole (TA), the major constituent in essential oil produced by anise, star anise, and fennel, whose function in skeletal muscle has not yet been elucidated. Therefore, we investigated whether TA influenced muscle differentiation in mouse C2C12 myoblasts. Cells were induced to differentiate using a differentiation medium with or without TA (50 or 200 mg/mL) daily for 5 days. We measured myotube length and diameter after differentiation days 1, 3, and 5 and analyzed the expression of myogenic markers (myoblast determination protein 1, myogenin, myocyte enhancer factor 2, muscle creatine kinase, and myosin heavy chain) and atrophy-related genes (atrogin-1 and muscle ring finger-1 [MuRF-1]) using quantitative real-time PCR. Additionally, we observed the expression of total protein kinase B (Akt) and phosphorylated Akt (p-Akt) using western blotting. Our data showed that TA significantly induced the formation of smaller and thinner myotubes and reduced the myogenic factor expression. Furthermore, the atrogin-1 and MuRF-1 expression markedly increased by TA. Consistent with these findings, TA significantly decreased the expression of total Akt and p-Akt. Taken together, these results indicate that TA inhibits myogenic differentiation of C2C12 cells via reduction of both total Akt and p-Akt. Our findings may provide valuable insights into the impact of PAA on individuals at risk of muscle atrophy.
