목적: 본 연구는 건강 행동을 설명하기 위해 새롭게 떠오르고 있는 시간적 자기조절 이론에 대한 부분적인 검증으로, 운동 참여 정도에 따라 운동의 이득과 비용을 인지하는 시점에 차이가 있는지 확인하고 의도와 의도-행동 불일치에 있어서 조절효과를 나타내는 변인을 검증하는 것에 있다. 방법: 이를 위하여 단계적 변화모형의 운동 행동 변화 단계(Prochaska & Marcus, 1994)를 기준으로 계획, 준비, 행동, 유지 단계에 해당하는 20대 여성을 단계별로 25명씩 모집하여 총 100명을 대상으로 3가지 인지테스트를 실시하고 자료를 수집하였다. 수집된 자료는 SPSS 21.0을 이용하여 기술통계, 요인분석 및 신뢰도 분석, 상관관계 분석, 일원배치 분산 분석, 단순 회귀분석, 다중 회귀분석을 실시하였다. 결과: 첫째, 운동행동 단계와 관계없이 모든 집단에서 운동에 대한 비용을 이득 보다 먼저 인지하는 것으로 나타났다. 그러나 계획단계보다 유지단계에서 운동에 대한 이득을 인지하는 시점이 빨랐고, 이득과 비용을 인지하는 시간적 격차가 작은 것으로 나타났다. 둘째, 운동의도가 의도-행동 불일치에 유의 한 부(-)적 영향을 미치는 것으로 나타났다. 즉 의도가 높아질수록 의도-행동 불일치는 낮아지는 것으로 확인되었다. 셋째, 의도가 의도-행동 불일치에 영향을 미치는데 있어서 Stroop test의 불일치 조건 반응시간, Tower of London의 total move score 및 initial time이 조절 효과를 나타냈다. 넷째, 의도가 의도-행동 불일치에 영향을 미치는데 있어서 자기통제의 하위요인인 자제력과 집중력은 조절 효과를 나타내지 않았다. 결론: 본 연구는 시간적 자기조절 이론의 바탕이 되는 시간적 특성을 운동 단계에 따라 살펴보고, 자기 조절능력을 자기 통제의 개념과 구분하여 검증하였다는 것에 의의가 있다. 시간적 자기 조절이론이 건강 행동에 대한 설명력을 높이고 다양한 연 구 분야에서 유용성을 확장해 나가기 위해선 추후 이론을 구성하는 변인들에 대한 추가적인 검토가 함께 이루어져야 할 것으로 사료된다.

Angelica gigas Nakai (AGN) is a traditional medicinal herb especially in Korea. It contains pyranocoumarins, which are major active components including decursin (D) and decursinol angelate (DA). This study was carried out to determine the change in active component content and antioxidant activity depending on the root diameter of AGN. Several processing steps are involved to use AGN roots as medicine. The dried AGN roots are divided into body (B), thick root (TkR), medium root (MR) and thin root (TnR) according to their diameter before cutting into medicine. The recovery rates of each root parts per 100 ㎏ were measured as 32.3±2.5, 9.0±1.0, 39.3±2.1 and 15.0±1.0%, respectively and the mean diameters were measured as 51.95±4.55, 7.05±0.89, 2.88±0.49 and 1.57±0.32 ㎜. Two index components, D and DA, were analyzed. The change of both D and DA content showed a similar tendency. Both D and DA content were increased as the root diameter decreased (higher in TnR). In addition, antioxidant activity was higher in B and TnR, and lower in TkR and MR than control. This study showed that the thinner the root diameter, the higher the D and DA content in AGN roots and that TnR has excellent antioxidant activity compared to other root parts, suggesting that the thinner root part of AGN could be used as a potential material.

Arsenic is among the heavy metals commonly found in aqueous environments. Iron oxide is known as an efficient adsorbent for the arsenic. A new synthetic method was applied to provide iron oxide giving a large specific surface area. The mixing method affects the formation of iron oxide. Ultrasonic waves assisted the formation of very fine iron oxide in an organic phase. The synthesized iron oxide is amorphous type with a high surface area of more than 181.3 m2/g. Sorption capacity of the synthesized adsorbent was relatively very high for arsenic and varied depending on the oxidation state of arsenic: a higher capacity was obtained with As(V). Lower solution pH provided a higher sorption capacity for As(V). The competitive effect of co-exist anions such as chloride, nitrate, and sulfate was minimal in sorption capacity of the iron oxide for arsenic.

Background: Angelica gigas Nakai is a perennial herb belonging to the family Umbelliferae. Its roots are utilized in traditional medicine. The aim of this study was to increase the yield of and the content of two indicator components (decursin and decursinol angelate) in A. gigas Nakai. Methods and Results: The roots of A. gigas Nakai were harvested 4-times from late August to late October in 2017. Two agents (trace element-TE, and plant hormone-HM) were applied 4 times at intervals of 2 weeks. The content of the two indicator components were analyzed by high performance liquid chromatography. The HM treatment showed the greatest increase in underground part yield and root diameter. The content of the two indicator components in the control (non-treatment) group was the highest in the underground part, but was higher in the aerial parts in the agent treatment group. After treatment with the agents, the content of the indicator components tended to decrease in the underground part. However, the total content of the indicator components in the two agent treatment groups exceeded the level of 6% set by the Korean Pharmacopoeia. Conclusions: The highest underground part yield was found in the HM treatment group, while the highest content of decursin and decursinol angelate were found in the control group. This study provides basic information for yield improvement in A. gigas.

Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside- Re content of ginseng roots, which are used as food, medicine, or cosmetic materials. Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per 1.62㎡ ranged from 43.4 to 61.4, while the weight of berries per 1.62㎡ was the greatest when they were collected 49 days after flowering. The root fresh weight per 1.62㎡ was increased by 0.21 - 1.00 ㎏ compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering. Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.

Background : Ginseng root rot is a devastating disease caused by the fungus, Ilyonectria mors-panacis that generally attacks younger roots (-2 years), leading to defects in root quality, ginsenoside accumulation and also life cycle of the plant. Hence, there is an indispensable need to develop strategies resulting in tolerance against ginseng root rot. The protective role of silicon during pathogen infestation is well documented in other plant systems and a previous study demonstrated that silica nanoparticles are absorbed and accumulated more than the bulk silica in maize. However, the role of silica in ginseng-root rot pathosystem is unknown. Methods and Results : In the present study, we evaluated the effect of silica nanoparticles (N-SiO2) in Panax ginseng during I. mors-panacis infection. Long term analysis (30 dpi) revealed a striking 50% reduction in disease severity index upon 1 mM and 2 mM treatment of N-SiO2. However, N-SiO2 did not have any direct antifungal activity against I. mors-panacis. Candidate genes and metabolites based approach revealed jasmonic acid (JA) mediated sterol accumulation and incresed ginsenside biosyntesis as the key transcriptional reprogramming events orchestrated by N-SiO2 during the fungal infection. Conclusion : In a nut shell, N-SiO2 administration induces transcriptional reprogramming in ginseng roots, leading to increased phytosterol and ginsenosides synthesis resulting in enhanced tolerance against I. mors-panacis.

Background : Rehmannia glutinosa belonging to the family of Scrophulariaceae have been utilized as a traditional medicine. This study was conducted to elucidate an effect of air curing for seed rhizome of R. glutinosa on storaging ability and yield. Methods and Results : The root of R. glutinosa cultivar (Dagang) was harvested in the end of November.

Aa-AgNPs and Aa-Au NPs were found to be spherical, face-centered cubic nanocrystals with hydrodynamic diameter of 190 and 258 ㎚. In vitro cytotoxic analysis revealed that up to 50 ㎍/㎖-1 concentration Aa-Au NPs did not exhibit any toxicity on 3T3-L1, HT29 and MCF7 cell lines, while being specifically cytotoxic to A549 cell line. On the contrary, Aa-Ag NPs displayed a significantly higher toxicity in all cell lines specially MCF7 cell line. ROS generation was not affected by Aa-Au NPs, but Aa-AgNPs has a higher potential to induce oxidative stress in A549 cells than HT29 and MCF7 cells. Aa-Au NPs have the potential for anticancer agent during lung cancer treatment. Aa-AgNPs is also exhibited to inhibit cell migration by induce oxidatie stress. Conclusion : The Aa-Au/AgNPs might have the anticancer potential and might be effective in the lung cancer therapy, however further evaluation is must needed.

증강현실(AR) 게임 유행과 함께, 게임 유저들이 게임 중 지역 사회에 각종 피해를 발생키고, 이에 대해 게임 회사 책임을 묻는 새로운 유형의 민사 분쟁이 발생하고 있다. 이 같은 분쟁은게임을 하지 않는 제3자들에게도 피해를 끼친 점에서 기존 게임 상 분쟁과 다르다. 본 글은 해외 분쟁 사례들을 살펴보고, 무단침입, 생활방해, 부당이득과 같은 피해 유형, 관련 국내외법과판례들을 분석한다. 정리 결과, AR 게임 피해 사실만으로는 게임 회사에 법적 규제나 손해배상을 가하기 힘들다. 사전적 규제는 헌법상 과잉금지 원칙 위반 여부, 사후적 규제는 기존 법상의방해 유형, 게임과 피해 사이 인과 관계, 피해의 구체성과 지속성 등을 검토해 결정해야 한다.

모바일은 새로운 커뮤니케이션 수단을 넘어서 일상이 되어가고 있으며 현대정치 문화에서도 모바일을 활용한 홍보는 필수적인 요인이 되어 있다. 많은 정치 후보자들이 선거 캠페인 문화 및 전략에 있어 모바일을 비중이 높은 홍보수단으로 활용하고 있지만 이에 비해 모바일을 활용한 정치 광고에 대한 연구가 부족한 것이 현실이다. 특히 모바일을 활용한 문자메시지 홍보는 현대 정치 문화로 자리 잡아 가고 있으며, 이에 따라서 좀 더 정교하고 유권자들의 호감을 이끌어낼 수 있는 모바일 메시지 활용이 필요한 시점임을 알 수가 있다. 본 연구는 이러한 배경 하에 모바일을 활용한 정치 후보자들의 문자메시지에 대한 인게이지먼트 요인들이 유권자 반응에 미치는 영향을 알아보고자 연구를 진행하였다. 기존 선거에 사용되었던 문자메시지를 수집 분석해 상호 이해형, 조작형, 정보 전달형으로 나누고 선거권이 있는 전국 남녀 120명을 통해 인게이지먼트 속성(만족, 유익성, 주목성)이 유권자 반응에 미치는 영향을 서베이를 통해 분석해 보았다. 분석결과 첫째, 상호이해형 메시지에서 후보자태도에 영향을 미치는 요인은 만족과 유익성이고 투표의향에 영향을 미치는 요인은 만족인것으로 나타났다. 둘쨰, 조작형 메시지에서는 만족과 유익성 요인이 후보자 태도에 영향을 미치는 것으로 나타났고 투표의향에 영향을 미치는 요인은 만족과 주목 요인인 것으로 나타났다. 셋째, 정보 전달형 메시지에서는 만족과 유익성 요인은 후보자 태도에, 만족과 주목성 요인은 투표의향에 영향을 미치는 것으로 나타났다. 따라서 인게이지먼트 요인이 메시지 유형별로 유권자 반응에 미치는 영향에 대한 연구는 효과적인 메시지 운용 전략을 펼칠 수 있으며, 한 두표 차이로 당락이 결정되기도 하는 선거에서 향후 더 발전적이고 정교한 선거 캠페인 문화에 실무적 시사점을 제공할 수 있을 것이다.
