This paper reports a safe and environmentally-benign demilitarization method for the K305 35mm CS gas grenades launcher set(also known as E-8 launcher). The launcher system was disposed by a two-step process; complete recovery of the explosive cords and the gas grenades from the launcher followed by incineration of the recovered items in the APE-1236 Flashing Furnace. All of the 64 grenades within the 16 tubes of the E-8 launcher were safely recovered and incinerated. In this study, 32 sets of the launcher were used to make a standard operating procedure for the safe demilitarization of the launcher system and the 35mm CS cartridges were all safely destroyed in the experimental burning tests meeting the related environmental regulations.

산지(産地) 반양직묘포(半養直苗圃)(활엽수(闊葉樹)를 많이 넣고 여러번 경운(耕耘)한 밭흙을 곱게 쳐서 만든 묘포(苗圃)) 29개포장(個圃場)에서 묘포토양(苗圃土壤) 이화학성(理化學性)과 묘삼수량(苗蔘收量)과의 관계룰 조사한 결과(結果)는 다음과 같다. 1. 사용가능묘삼생산량(使用可能苗蔘生産量)은 간(間)($90{\times}180cm$) 당(當) $362{\pm}226$본(本)이었다. 2. 세사(細砂)+극세사(極細砂)의 함량(含量)이 많을수록 묘삼개체근중(苗蔘個體根重)이 감소(減少)되었다. 3. 묘포토양내(苗圃土壤內)에서 pH는 OM, K, Ca 및 Mg와, EC는 Ca, Mg 및 N와 각각(各各) 정상관(正相關)이 있었다. 4. 묘삼개체중(苗蔘個體重)은 토양내(土壤內) pH 상승(上昇)과 OM, K, Ca 및 $P_2O_5$ 함량(含量)이 많을수록 증가(增加)되나 N과는 상관(相關)이 없었다. 5. 토양내(土壤內)에 $P_2O_5$, K 및 Ca 함량(含量)이 많을수록 묘삼근내(苗蔘根內) 함량(含量)이 증가(增加)되었다. 6. 근내(根內)의 $P_2O_5$, K의 흡수(吸收)가 증가(增加)될수록 묘삼개체근중(苗蔘個體根重)이 증가(增加)되었다. To get the basic information about ginseng seedling production, yield of ginseng seedling and soil physico-chemical components of Ban-Yang-Jik (semimodified soil) nursery in 29 farmer's field were investigated. The number of available seedling per Kan (Kan means $180{\times}90cm$ area) is $362{\pm}226$. Root weight per seedling was negatively correlated with ammount of fine and extremely fine sand. Positive correlations were shown between pH and OM, K, Ca and Mg, and also between EC and Ca, Mg and ammonium and nitrate nitrogen in soil of nursery. There were significant linear relations between root weight and OM, K, Ca and Mg in soil of nursery. On the other hand, quadratic relation was held between the root weight and $P_2O_5$, but the root weight has no correlation with nitrogen. The nitrogen contents of soil might not influence on the growth of ginseng seedling as greatly as those of $P_2O_5$, K and Ca. The contents of $P_2O_5$, K and Ca in root were increased with increase of the contents of $P_2O_5$, K and Ca in soil of nusery, respectively. It showed the linear correlation between the root weight and $P_2O_5$ and Ca, otherwise quadratic correlation between the root weight and K in root.

Objective: The aim of this study was to investigate the wound healing effect of herbal ointment, Gamijaungo, on the burn-induced model. Reports about Gamijaungo on the wound healing effect by local application in mice model or human study have published in the several domestic or internationally, but most are anecdotal and lack solid scientific evidence. Method: We observed the morphologic and histologic changes in the burn-induced mice model. we counted white blood cell and platelet changes. we confirmed VEGF, PI3K and pAkt protein expression by Western blot analysis. Result: In this study, we observed that Gamijaungo showed strong wound healing effects in the morphologic and histologic changes in the burn-induced mice model. Also we found that the significant changes of white blood cell and platelet changes by the treatment of Gamijaungo. In molecular mechanism, we got the strong positive effect by Gamijaungo treatment on angiogenesis, a key process in the formation of the granulation tissue during wound healing. Conclusion: These findings suggest the potential use of Gamijaungo as a therapeutic in thermal burn-induced skin injuries.
