Soil organic matter and nutrient accumulation at the abandoned fields

박병배,신준환 한국산림과학회 2008 한국산림과학회지 Vol.97 No.5

Since vegetation significantly influences on soil carbon and nutrient storage, vegetation change has been focused on terrestrial carbon and nutrient cycling studies. In this study we investigated soil carbon and major nutrient capitals at the abandoned fields, which had different vegetation composition: a three year abandoned field (AGR3), two ten years abandoned fields (PD10 dominant with Pinus densiflora and Fraxinus rhynchophylla and PM10 dominant with Populus maximowiczii), and an over sixty years forest (FOR60), which were located at Hongcheon-gun, Kangwon-do, South Korea. Both main effects for organic matter (%) were significant: shallow soil > deep soil and FOR60 = PM10 > AGR3 = PD10. Nitrogen concentrations at PM10 were the highest, while the lowest at PD10. Available phosphorus concentrations were the highest at PD10, which were over 10 times of site FOR60 and AGR3 at 0-10 cm soil depth. The average organic matter (173 Mg ha-1) and nitrogen contents (10 Mg ha-1) of PM10 and FOR60 were higher than those of AGR3 and PD10 by 57% and 42%, respectively. The available phosphorus contents above 30 cm mineral soil at PD10 (3.8 Mg ha-1) and PM10 (1.3 Mg ha-1) were over 120 times and 40 times more than at FOR60. Calcium (3.7 Mg ha-1) and magnesium contents (2.8 Mg ha-1) at FOR60 were twice or three times higher than at other sites. Organic matter amounts in 0-10 cm and 10-30 cm soil had significant positive relationships with nitrogen, calcium, and magnesium contents, but not available phosphorus and potassium contents. This study could not identify the effect of chronological factor and vegetation composition on soil carbon and nutrient capital owing to diverse topography as well as limited study sites. However, this study suggests the accuracy of investigation for regional carbon and nutrient sequestration can be achieved by considering the period of abandoned time on the fields and the land use types. These results may suggest the benefits of forest restoration for soil carbon and nutrient accumulation in marginal agricultural lands in South Korea.

This study was conducted to determine the optimum amount of fertilizer for Fraxinus rhynchophylla, Fraxinus mandshurica, Pinus koraiensis, and Abies holophylla seedlings with vector analysis. As the amount of fertilizer increases, the height and root collar diameter of F. rhychophylla and F. mandshurica increased and those of P. koraiensis and A. holophylla were not significantly changed. Treatment 1x (N 6.9 g m-2, P 3.1 g m–2, K 3.7 g m-2), 2x (two times of 1x) and 4x (four times of 1x) improved the dry weight of F. rhynchophylla by 43, 11, and 87% and that of F. mandshurica by 36, 145 and 143% respectively compared with the control. However, the dry weight of P. koraiensis and A. holophylla was not different among fertilization treatments. The responses of vector exhibit a different inclination depending on tree species and the amount of fertilizer. F. rhynchophylla is in the status of N “deficiency” which means the N concentration does not increase as much as the increment of growth and nutrient content; F. mandshurica is in a condition of N “dilution” which refers the concentration decreases since the growth increases more than the absorption of nutrients; P. koraiensis and A. holophylla show the state of N “antagonism” which indicates the concentration decreases slightly while the growth does not increase nearly. This study suggests that F. rhynchophylla and F. mandshurica require to fertilize 2x or more and P. koraiensis and A. holophylla do not need to fertilize at the initial stage of outplanting. 묘목 생산성과 적절한 품질을 유지하기 위하여 시비는 매우 중요하지만, 수종에 따른 최적의 시비량을 결정하기는 어렵다. 이 연구에서는 경제림 육성 수종인 물푸레나무, 들메나무, 잣나무, 전나무를 대상으로 복합비료 1x(N 6.9 g m-2, P 3.1 g m-2, K 3.7 g m-2), 2x(1x의 2배), 4x(1x의 4배) 처리가 묘목의 생장과 양분변화에 미치는 영향을 양분벡터분석(Vector diagnosis)을 이용하여 정량화하였다. 시비량이 증가함에 따라 물푸레나무와 들메나무의 수고와 근원경은 증가하는 경향을 보였고 잣나무와 전나무는 시비량에 따른 차이를 보이지 않았다. 처리 1x, 2x, 4x는 대조에 비하여 물푸레나무의 건중량을 각각 43, 11, 87% 증가시켰고, 들메나무는 각각 36, 145, 143% 더 증가시켰다. 반면 잣나무와 전나무 건중량은 시비량에 따른 유의한 차이가 없었다. 시비에 대한 양분벡터반응은 수종과 시비량에 따라 상이한 경향을 보였는데, 물푸레나무 조직의 질소 농도는 생장 및 질소함량의 증가만큼 증가하지 않는 “양분결핍” 상태였고, 들메나무는 흡수한 것보다 생장이 증가하여 농도가 감소하는 “양분희석” 상태였으며, 잣나무와 전나무는 생장이 거의 증가하지 않으면서 농도는 약간 감소하는 “과량길항” 현상을 보였다. 본 연구는 물푸레나무와 들메나무는 처리 2x 또는 그 이상의 시비가 요구되고, 잣나무와 전나무의 경우 초기 시비를 하지 않아도 생장과 양분 흡수에 문제가 없음을 보여주고 있다.

This study aimed to identify the respiratory viral etiology and clinical features in febrile neonates and young infants younger than 3 months of age. From June 2015 to March 2016, 126 patients who admitted to the pediatrics department of Kwangju Christian Hospital due to febrile illness (body temperature ≥ 38.0℃) without definite focus of fever. We tested nasopharyngeal aspiration specimens with real time reverse transcriptase polymerase chain reaction. Respiratory viruses identified in 66 patients, and not identified in 60 patients. Among identified viruses, the most common pathogen was rhinovirus. Respiratory virus identified patients showed significantly higher presence of sibling (p=0.015), sibling who attending day care center (p=0.022), respiratory symptoms of family members (p=0.022), concomitant respiratory symptoms of the patient (p=0.001).

Helianthus tuberosus is a perennial plant in the genus, Asteraceae. Pork potato has various pharmacological functions such as improving constipation, preventing bowel disease, inhibiting colon cancer, reducing serum cholesterol, lowering blood lipids, and enhancing blood sugar. This study investigated the physicochemical properties of fermented milk by adding Helianthus tuberosus powder. During the fermentation process, the pH of the fermented milk with added Helianthus tuberosus was higher after 16 hours of fermentation. At 48 hours of fermentation, the pH decreased to 3.70, 3.65, 3.63, and 3.59 with 0% (the control group), 1%, 3%, and 5% Helianthus tuberosus added, respectively. In the last 48 hours of fermentation, the acidity increased to 2.35%, 2.57%, and 3.17% with 0% (the control group), 1%, 3%, and 5% Helianthus tuberosus added, respectively. The number of lactic acid bacteria increased as the quantity of Helianthus tuberosus added increased. The highest number of lactic acid bacteria was 9.96 log CFU/g after 16 hours of fermentation with a 5% addition of Helianthus tuberosus . After 48 hours of fermentation, the amount of lactic acid bacteria decreased to 7.84 log CFU/g and 7.88 log CFU/g in the control group and the 1% added Helianthus tuberosus group, respectively. The addition of 3% and 5% Helianthus tuberosus increased the lactic acid bacteria count to 9.48 log CFU/ g and 9.81 log CFU/g, respectively. As the fermentation time increased, oxalic acid and tartaric acid decreased but lactic acid increased. Lactose degraded galactose and glucose over time. After 48 hours of fermentation, the viscosity in the control, 1%, 3%, 5% added Helianthus tuberosus groups increased to 1,006 cP, 1,026 cP, 1,040 cP, and 1,106 cP, respectively. The antioxidant effect was higher in the 5% added Helianthus tuberosus group (84.14%) than in the control group (80.39%) at 48 hours of fermentation. The concentration of polyphenol was 1.6 mg/g and antimicrobial activity was strong against E. coli and Staphylococcus aureus.

비소세포폐암의 세포독성 항암화학요법

박병배 한양대학교 의과대학 2014 Hanyang Medical Reviews Vol.34 No.1

Non-small-cell lung cancer is one of the leading causes of deaths from cancer worldwide. There have been remarkable advances in the targeted treatment of advanced non-small cell lung cancer (NSCLC) over the past several years. Survival outcomes are steadily improving as management paradigms shift in the diagnosis and treatment of advanced NSCLC. Customizing treatment based on histology and molecular typing has become a standard of care in this era of targeted therapy. Even as new chemotherapeutic agents are proving effective, a pivotal role for platinum-based chemotherapy doublets has been confirmed. Maintenance chemotherapy has become an option, but determining which patients will most benefit from it remains controversial in the real-world setting. Ongoing efforts to overcome resistance to targeted agents utilizing combination regimens of chemotherapy plus targeted agents, are currently being explored and optimized. This review highlights recent developments in novel chemotherapeutics. Despite advances in molecular medicine, there remains an essential role for chemotherapy in advanced NSCLC, even in the recent targeted therapy era.
