In flue-cured tobacco, the relationships between the quality of tobacco leaves (productivity according to quality grade) and specific meteorological factors were noted showing different significances according to different seasons during the growing period of the tobacco plants. The thick leaf high quality was significantly correlated with average temperature in late April, late May, early July and late July. The degree of contribution was greatest in middle May and lowest in late May. In the highest and lowest temperatures, the relations to leaf quality had similar tendency like in the average temperature; the thick leaf low quality showed opposite tendency relative to the high quality in the degrees of correlations and contributions. Amount of precipitation was significantly correlated with the thick leaf high quality in late April, early May, middle May, late June and late July. The degree of positive contribution was shown in order of late April, middle July and early July, and that of negative one was in order of middle June, early June and late June, respectively. Duration of sunshine period was highly associated with thick leaf high quality of tobacco leaves in all of the growing season except for middle April and middle July. The degree of positive contribution was in order of late May, late April, early July and middle July, and that of the negative one was in order of late June, early May, middle June and middle May.

The study was conducted to investigate the relationships between tobacco leaf pro-duction rate by quality grade and the value of climatic factors in tobacco growing season. In flue cured tobacco（NC82）, high quality was positively corretated with precipitation in late April and May, with sunshine' hours in early May and late June, with average temperature in middle July, significanly. In Burley tobacco（Br21）, high quality was positively correlated with precipitation in late April and May, with sunshine hours in early May and early July, with average temperature in middle July, significantly.

Seasonal climatic factors associated with tobacco quality grade and production rate were analyzed. The degree of influence on yield distribution rate in high guality tobacco leaues was highly positive with the average temperature in early May, but negatively related to those in late May and early June. Positive correlations were noticed between the degree of influence and sunshine hours in Middle June, late June and late May in decrease order, while negative degree of influence was higher in early May than in late May, The order influenced by recipitation in a positive direction was early May, late May and middle May. Negative influence was noticed in middle and early June with a great degree.

Until the late 19th century, $\ulcorner$Gagogwonryu(歌曲源流)$\lrcorner$ was a collection of songs which had powerful influence on Gagog tradition. However, its role on Gagog(歌曲) tradition since then is less well known. Generally, it is presumed that Gagog tradition might disappeared by giving way to modern song genre. So this article question that $\ulcorner$Gagogwonryu$\lrcorner$ became extinct rapidly between the late 19th century and early 20th century, and follow $\ulcorner$Gagogwonryu$\lrcorner$ tradition of early 20th century. Gagog instruction for beginner had a clue to answer this question. This instruction was written by Ha Son-il(河順一) who was a teacher and singer in a private music institute. named 'ChoyangGurakbu(調陽俱樂部). Accordingly, this article has processed two phases in order to find out this question. First of all, this article analyzed Gagog instruction that Ha soon-il edited. As a result, it found out that Gagog instruction included the whole $\ulcorner$Gagogwonryu$\lrcorner$'s contents in the 19th century and was transmitted actively until the early 20th century. Second, this article found out $\ulcorner$Gagogwonryu$\lrcorner$ tradition of the early 20th century by analyzing character of ChoyangGurakbu. And also this article discovered ChoyangGurakbu had been managed by an vigorous aid association. Gagog instruction for beginner written by Ha Son-il had spreaded from strength to strength in the early 20th century.

잇꽃(Carthamus tinctorius L.)은 국화과에 속하는 두해살이 초본 식물로 한자명은 홍화(紅花), 영명으로는 Safflower를 사용하고 있다. 우리나라의 잇꽃 재배는 2010년 39ha 수준이 재배되다가 2014년에는 76ha까지 확대되었으나, 점차 감소하는 추세를 보이고 있으며 2020년에는 52ha가 재배되고 있는 것으로 보고되었다. 잇꽃은 종자를 약용으로 이용하거나 꽃잎을 건조하여 천연 염색제 및 향신료로 이용하고 있으나, 일본 산형(山形)현에서는 잇꽃의 경관적 가치를 이용해 홍화 축제를 개최함으로써 소득작목으로 자리매김하고 있다. 본 연구는 지리산을 중심으로 한 준고랭지 지역에서 잇꽃의 경관적 가치의 활용 가능성을 검토하고자, 국립농업유전자원센터로부터 총포에 가시가 없는 무가시형 유전자원(IT323225, IT333473, IT333482)을 분양받아 가시가 있는 재배종과 파종시기별로 개화 특성 등을 비교하였다. 표고 500m 준고랭지의 비가림 하우스에서 3월 하순부터 6월 상순까지 파종시별로 출현율을 검토한 결과, IT 323225 자원은 관행의 3월 하순 파종에서도 40.5%의 낮은 출현율을 보였다. 3월 하순 파종에서 재배종은 6월 22일경에 개화기에 도달하였으나, 무가시형 유전자원들은 7월 2일~5일경에 개화기에 도달하여 만생종의 특성을 보였다. 파종시기를 늦춰 5월 하순에 피종하는 경우 무가시형 자원들은 7월 27일~29일경에 개화기에 도달하였으며, 개화기 전후의 개화 지속기간은 8~10일이 소요되어 3월 하순에 파종하여 7월 상순에 개화하는 경우보다 2~4일이 단축되는 경향이었다. IT333473 자원의 개화기 초장은 5월 하순 파종하는 경우 관행의 3월 하순 파종보다 43.6%가 즐어든 71.1cm를 보였고, 분지수는 41.6% 감소한 8.0개/주 수준을 보였다. 식물체당 착화수 또한 파종시기를 늦춤에 따라 감소하는 경향이었으나 화당 종자수는 IT323225 자원은 5월 중순과 하순 파종시에 증가하는 양상이었고 IT333473 자원과 IT333482 자원은 재배종과 같이 감소하였다. 하계 휴양지로 각광받고 있는 지리산권에서 무가시형 잇꽃 자원의 경관적 가치 활용 가능성을 검토한 결과, 파종시기를 5월 하순으로 늦추는 경우 성수기인 7월 하순과 8월 상순에 개화가 가능하였다. 또한 식물체의 초장이 71.1~83.6cm 수준으로 단축되어 경관 조성에 유리한 특성을 보였다.

Clearwing moths (Lepidoptera: Sesiidae) are economically important pests of fruit trees, such as apple, peach, and grape in Korea. Larvae feed on the phloem and cambium within tree branches of host plants. In this study, the seasonal fluctuation in male catches of four clearwing moths, Synanthedon haitangvora, S. bicingulata, Nokona regalis, and Glossosphecia romanovi, were monitored with the respective sex pheromone traps in Suwon for three years. In apple orchards, S. haitangvora males were captured from May to October, with two peaks in early June to middle June and late August to early September. Similarly, S. bicingulata males were trapped from May to October, with two peaks in late May and late August to middle September in peach orchards. In vineyards, N. regalis males were captured from late May to middle June with one peak in late May to early June, while G. romanovi males were trapped from early June to late July with one peak in late June to early July.

The pathogenic fungi associated with blight of leaf and stem in peony were leaf spot (Alternaria sp.), powdery mildew (Erysiphe aquilegiae) and rust (Cronartium flaccidum). The infection of leaf spot and powdery mildew begins from late April to midMay and rust was infected in early June. Blight time of aerial part in peony started from late May and the ratio of blight on leaf and stem was more than 50% in late Aug. Yields of root by the incidence time of blight of leaf and stem were 69.1% in late June, 65.4% in late July and $87.6{\sim}92.7$% in August and September. The number of root of more than 10mm in root diameter blighted in late June and July was much lower than in August, but the paeoniflorin content in the former was much higher than the latter.

As attractive lips are important component of appealing faces, the study was conducted to investigate the association of mouth-breathing and thickness of lower lips in mouth-breathers and nasal-breathers. The subjects were 436 adolescent patients aged 8~18 years who took cephalometrics. The results were as follows. The ratio of lower lip thickness to that of upper lip thickness in mouth breathing and nasal breathing groups were $1.13{\pm}0.14$, $1.02{\pm}0.14$, respectively. According to subjects' skeletal pattern, the ratio in Class I sample was $1.05{\pm}0.09$. Class II subjects showed $1.20{\pm}0.12$, and Class III showed $0.97{\pm}0.11$. Mouth - breathers had higher lower/upper lip ratio than nasal breathers meaning their lower lips were thicker. Skeletal Class II patients group showed the most thickest lower lips among Class I, II, III subgroups.
